Description

Die Erfindung betrifft ein Reinigungsfahrzeug zur Reinigung einer Landezone einer Flugzeuglandebahn.The invention relates to a cleaning vehicle for cleaning a landing zone of an aircraft runway.

In der Landezone einer Flugzeuglandebahn kommt es aufgrund der vielen landenden Flugzeugen zu erheblichem Gummiabrieb, wenn die Räder der Flugzeuge durch Kontakt mit der Flugzeuglandebahn auf die Geschwindigkeit des Flugzeugs beschleunigt werden. Hierbei lastet gleichzeitig ein hoher Druck auf dem Flugzeugrad, wodurch der Gummiabrieb hoch verdichtet wird. Dieser Gummiabrieb kann, wenn die Schichtdicke des Gummiabriebs dick genug wird, zur Reduktion des Reibwerts zwischen Flugzeugreifen und Landebahn sorgen. Besonders bei einer nassen Flugzeuglandebahn verringert sich dann die Haftung des Flugzeugreifens auf der Flugzeuglandebahn.In the landing zone of an aircraft runway, there is considerable gum abrasion due to the many landing aircraft when the wheels of the aircraft are accelerated to the speed of the aircraft by contact with the aircraft runway. At the same time a high pressure on the aircraft wheel, whereby the rubber abrasion is highly compressed. This rubber wear can, if the layer thickness of the rubber wear becomes thick enough, reduce the coefficient of friction between the aircraft tire and the runway. Especially in a wet aircraft runway then reduces the liability of the aircraft tire on the aircraft runway.

Aus dem Stand der Technik sind Reinigungsfahrzeuge und Verfahren bekannt, bei denen der Gummiabrieb innerhalb einer Landezone einer Flugzeuglandebahn mittels einem Wasserhöchstdruck (WHD)-Verfahren entfernt wird. Eine Reinigung wird so ca. vier bis sechs Mal jährlich durchgeführt. Hierfür wird ein Fahrzeug mit einem Wassertank benötigt, das über die Landebahn fährt und das Wasser unter höchstem Druck auf die Landezone der Flugzeuglandebahn aufbringt. Ein weiteres Fahrzeug wird dafür benötigt, das durch die Reinigung entstehende Schmutzwasser aufzusammeln und zu entsorgen. Bei der Entsorgung muss das Wasser vom dem Gummiabrieb getrennt werden. Dies bedeutet einen enormen Aufwand. Daher ist eine solche Reinigung der Landezone auch besonders kostenintensiv.Cleaning vehicles and methods are known in the prior art in which rubber abrasion within a landing zone of an aircraft runway is removed by means of a high pressure water (WHD) method. Cleaning is carried out about four to six times a year. For this, a vehicle with a water tank is needed, which runs over the runway and applies the water under the highest pressure on the landing zone of the aircraft runway. Another vehicle is needed to collect and dispose of the waste water produced by the cleaning. For disposal, the water must be separated from the rubber. This means a huge effort. Therefore, such a cleaning of the landing zone is also particularly costly.

Zusätzlich ist die Entsorgung des vom Wasser getrennten Gummis umweltbelastend. Der entfernte Gummiabrieb wird als Sondermüll entsorgt. Diese gesonderte Entsorgung bedeutet abermals einen hohen Aufwand und hohe Kosten.In addition, the disposal of the rubber separated from the water is harmful to the environment. The removed rubber is disposed of as hazardous waste. This separate disposal again means a lot of effort and high costs.

Außerdem ist eine Reinigung der Landezone mittels Wasserhöchstdruck-Verfahren witterungsabhängig. Eine Reinigung kann beispielsweise bei Schnee oder Eis nicht erfolgen, da das Wasser gefrieren würde. Außerdem wird durch den hohen Wasserdruck ebenfalls die Oberfläche der Flugzeuglandebahn angegriffen. Diese muss also nach einer bestimmten Anzahl von Reinigungen erneuert werden.In addition, a cleaning of the landing zone by means of high-pressure water method is weather dependent. A cleaning can not be done for example in snow or ice, as the water would freeze. In addition, the surface of the aircraft runway is also attacked by the high water pressure. This must therefore be renewed after a certain number of cleanings.

Dadurch, dass die Reinigung mit dem Wasserhöchstdruck-Verfahren so aufwendig und kostenintensiv ist, wird die Reinigung ca. vier bis sechs Mal jährlich durchgeführt. Es bildet sich also mindestens über drei Monate eine immer dicker werdende Gummischichtdicke, die dann über Nacht fast vollständig abgetragen wird. Es liegt somit eine stark schwankende Qualität der Landezone der Flugzeuglandebahn vor.The fact that cleaning with the high-pressure water process is so complicated and expensive, the cleaning is carried out about four to six times a year. Thus, for at least three months, an ever thicker rubber layer thickness is formed, which is then almost completely removed overnight. There is thus a strongly fluctuating quality of the landing zone of the aircraft runway.

Dies macht es für Piloten schwierig, einzuschätzen, wie gut die Haftung des Flugzeugs bei der Landung auf der Flugzeuglandebahn sein wird.This makes it difficult for pilots to assess how good the aircraft's adhesion will be when landing on the aircraft runway.

Zur Reinigung werden außerdem große Wassermengen benötigt, die die Umwelt belasten.For cleaning also large amounts of water are required, which pollute the environment.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, ein verbessertes Reinigungsfahrzeug und ein verbessertes Verfahren zur Reinigung einer Landezone einer Flugzeuglandebahn zu schaffen.In contrast, the invention has for its object to provide an improved cleaning vehicle and an improved method for cleaning a landing zone of an aircraft runway.

Diese Aufgabe wird durch die unabhängigen Patentansprüche gelöst. Ausführungsformen der Erfindung sind in den abhängigen Patentansprüchen gegeben.This object is solved by the independent claims. Embodiments of the invention are given in the dependent claims.

Die Erfindung betrifft ein Reinigungsfahrzeug zur Reinigung einer Landezone einer Flugzeuglandebahn. Das Reinigungsfahrzeug weist ein Fahrwerk zum Befahren der Landezone auf. Außerdem umfasst das Fahrzeug zumindest eine Laserquelle. Die Laserquelle ist zur Abgabe eines Laserstrahls in einem für die Ablation von Gummi geeigneten Frequenzbereich ausgebildet. Dies kann zum Beispiel ein CO2- oder ein YAG-Laser sein. Die Ablation des Gummis umfasst ein Verdampfen des Gummis. Das Gummi wird also durch den Laserstrahl so stark erhitzt, dass es verdampft. Zusätzlich umfasst das Reinigungsfahrzeug einen Strahlaufweiter für die Aufweitung des Laserstrahls. Der Strahlaufweiter kann beispielsweise eine optische Linse sein, die zur Aufweitung des Laserstrahls ausgebildet ist, z.B. eine Zerstreuungslinse.The invention relates to a cleaning vehicle for cleaning a landing zone of an aircraft runway. The cleaning vehicle has a chassis for driving on the landing zone. In addition, the vehicle comprises at least one laser source. The laser source is designed to emit a laser beam in a frequency range suitable for the ablation of rubber. This can be for example a CO 2 or a YAG laser. The ablation of the gum involves evaporation of the gum. The rubber is so heated by the laser beam that it evaporates. In addition, the cleaning vehicle comprises a beam expander for the widening of the laser beam. The beam expander may for example be an optical lens which is designed to widen the laser beam, for example a diverging lens.

Es trifft also beim Befahren der Landezone mit dem Reinigungsfahrzeug der aufgeweitete Laserstrahl auf die Oberfläche der Landezone. Dort befindlicher Gummiabrieb von Flugzeugreifen wird durch Ablation entfernt. Es ist zu beachten, dass der Gummiabrieb, der durch die Flugzeugreifen bei der Landung entstanden ist, hoch verdichtet ist. Es muss also ein Laserstrahl mit einer hinreichend großen Leistung verwendet werden, um einen so stark komprimierten Gummiabrieb verdampfen zu können.Thus, when driving on the landing zone with the cleaning vehicle, the expanded laser beam strikes the surface of the landing zone. There located rubber abrasion of aircraft tires is removed by ablation. It should be noted that the rubber abrasion caused by the aircraft tires on landing is highly compressed. So it must be a laser beam with a sufficiently large power can be used to evaporate such a highly compressed rubber abrasion can.

Nach Ausführungsformen der Erfindung umfasst das Reinigungsfahrzeug eine Absaugvorrichtung. Die Absaugvorrichtung ist zum Absaugen von bei der Ablation entstehenden Dämpfen ausgebildet. Die Absaugvorrichtung kann beispielsweise rund um den Bereich angeordnet sein, in dem der Laserstrahl auf die Landezone trifft. So werden entstehende Dämpfe optimal abgesaugt. Dadurch, dass sich das Reinigungsfahrzeug bei der Reinigung nach vorne Richtung bewegt, kann die Absaugvorrichtung auch hinter dem Bereich angeordnet sein, in dem der Laserstrahl auf die Landezone trifft. In diesem Fall fährt also die Absaugvorrichtung über den Bereich der Verdampfung und saugt dann die kurz zuvor entstandenen Dämpfe ab.According to embodiments of the invention, the cleaning vehicle comprises a suction device. The suction device is designed to aspirate fumes produced during ablation. The suction device may, for example, be arranged around the area in which the laser beam strikes the landing zone. Thus, the resulting vapors are optimally extracted. Due to the fact that the cleaning vehicle moves forward during cleaning, the suction device can also be arranged behind the area in which the laser beam strikes the landing zone. In this case, therefore, the suction device moves over the range of evaporation and then sucks the vapors formed shortly before.

Nach Ausführungsformen der Erfindung umfasst das Reinigungsfahrzeug eine Filtervorrichtung zur Filterung der Dämpfe. Dies kann beispielsweise ein Kohlefilter sein, der Schadstoffe aus dem entstandenen Dämpfen herausfiltert. Ein solcher Filter wird regelmäßig erneuert, damit die Filterwirkung auf einem hohen Niveau bleibt.According to embodiments of the invention, the cleaning vehicle comprises a filter device for filtering the vapors. This can be, for example, a carbon filter that filters out pollutants from the resulting vapors. Such a filter is renewed regularly, so that the filter effect remains at a high level.

Nach Ausführungsformen der Erfindung umfasst das Reinigungsfahrzeug einen Katalysator zur Katalyse der Dämpfe.According to embodiments of the invention, the cleaning vehicle comprises a catalyst for catalyzing the vapors.

Nach Ausführungsformen der Erfindung weist das Fahrzeug Mittel zur Lenkung des Laserstrahls auf die Landezone auf. Außerdem umfasst das Fahrzeug eine Steuerung zur Steuerung des Laserstrahls. Die Lenkung des Laserstrahls ist durch die Steuerung steuerbar. Der Laserstrahl ist durch die Steuerung in zumindest einer Dimension über die Landezone bewegbar. Vorzugsweise ist der Laserstrahl in einer ersten Richtung über die Landezone bewegbar, wobei die Bewegungsrichtung des Reinigungsfahrzeugs mit der ersten Richtung einen Winkel einschließt. Vorzugsweise liegt der Winkel zwischen 70 und 110°. So wird eine möglichst optimale Reinigung der Landezone erreicht. Die Mittel zur Lenkung des Laserstrahls können beispielsweise Spiegel oder Lichtwellenleiter, wie zum Beispiel Glasfasern, sein.According to embodiments of the invention, the vehicle has means for directing the laser beam to the landing zone. In addition, the vehicle includes a controller for controlling the laser beam. The steering of the laser beam is controllable by the controller. The laser beam is movable by the controller in at least one dimension over the landing zone. Preferably, the laser beam is movable in a first direction over the landing zone, wherein the direction of movement of the cleaning vehicle with the first direction forms an angle. Preferably, the angle is between 70 and 110 °. This ensures the best possible cleaning of the landing zone. The means for directing the laser beam may be, for example, mirrors or optical waveguides, such as glass fibers.

Die Laserquelle kann sich also entweder direkt unterhalb des Reinigungsfahrzeugs befinden und direkt auf die Landezone der Flugzeuglandebahn abstrahlen, wobei sich zwischen Laserquelle und Landezone noch der Strahlaufweiter befindet. Alternativ kann sich die Laserquelle an einem anderen Ort im Reinigungsfahrzeug oder am Reinigungsfahrzeug befinden. Der Laserstrahl wird dann mit dem Spiegelsystem oder dem Lichtwellenleiter so gelenkt, dass er auf den Strahlaufweiter und danach auf die Landezone trifft.The laser source can therefore either be located directly below the cleaning vehicle and radiate directly onto the landing zone of the aircraft runway, wherein the beam expander is still located between the laser source and the landing zone. alternative The laser source may be located elsewhere in the cleaning vehicle or on the cleaning vehicle. The laser beam is then directed with the mirror system or optical fiber so that it meets the beam expander and then the landing zone.

Nach Ausführungsformen der Erfindung ist die Steuerung für eine Bewegung des Lasers in einer ersten Richtung ausgebildet und das Reinigungsfahrzeug für eine Bewegung in einer zweiten Richtung. Die erste und die zweite Richtung schließen einen Winkel ein.According to embodiments of the invention, the controller is configured to move the laser in a first direction and the cleaning vehicle to move in a second direction. The first and second directions include an angle.

Nach Ausführungsformen der Erfindung umfasst das Reinigungsfahrzeug zumindest eine Ultraschall-Sendevorrichtung und zumindest eine Ultraschall-Messvorrichtung. Die Ultraschall-Sendevorrichtung ist zur Aussendung eines Ultraschallsignals in Richtung der Landezone ausgebildet. Die Ultraschall-Messvorrichtung ist zur Messung eines von der Landezone reflektierten Ultraschallsignals ausgebildet. Die zumindest eine Ultraschall-Messvorrichtung ist zur Berechnung von Werten einer Schichtdicke des Gummiabriebs in einem Bereich der Landezone unter Verwendung des reflektierten Ultraschallsignals ausgebildet. Das Reinigungsfahrzeug weist zusätzlich einen Datenspeicher zur Speicherung der berechneten Schichtdickenwerte auf. Die berechneten Schichtdickenwerte werden also von der Ultraschall-Messvorrichtung in dem Datenspeicher gespeichert. Vorzugsweise geschieht die Messung der Schichtdicke des Gummiabriebs nach der Ablation durch den Laser. Der Datenspeicher kann beispielsweise nach der Reinigung ausgelesen werden. Alternativ oder zusätzlich kann der Datenspeicher Daten an ein Anzeigegerät in einer Fahrerkabine des Reinigungsfahrzeugs ausgeben. Dem Fahrer kann so schon während des Reinigungsvorgangs angezeigt werden, wie dick die Schichtdicke des Gummiabriebs nach der Laserablation noch ist.According to embodiments of the invention, the cleaning vehicle comprises at least one ultrasound transmitting device and at least one ultrasound measuring device. The ultrasonic transmitting device is designed to emit an ultrasonic signal in the direction of the landing zone. The ultrasonic measuring device is designed to measure an ultrasound signal reflected by the landing zone. The at least one ultrasonic measuring device is designed to calculate values of a layer thickness of the rubber abrasion in a region of the landing zone using the reflected ultrasound signal. The cleaning vehicle additionally has a data memory for storing the calculated layer thickness values. The calculated layer thickness values are thus stored by the ultrasonic measuring device in the data memory. Preferably, the measurement of the layer thickness of the rubber abrasion occurs after the ablation by the laser. The data memory can be read, for example, after cleaning. Alternatively or additionally, the data memory may output data to a display device in a driver's cab of the cleaning vehicle. The driver can already be shown during the cleaning process, how thick the layer thickness of the rubber abrasion after laser ablation is still.

Bei der Auslesung des Datenspeichers nach erfolgter Reinigung der Landezone können die Messwerte weiterverarbeitet werden. So kann beispielsweise die ordnungsgemäße Reinigung der Landezone nachgewiesen werden.When reading the data memory after cleaning the landing zone, the measured values can be further processed. For example, the proper cleaning of the landing zone can be proven.

Nach Ausführungsformen der Erfindung umfasst das Reinigungsfahrzeug zwei Ultraschall-Sendevorrichtungen und zwei Ultraschall-Messvorrichtungen. Dies kann vorteilhaft dafür sein, dass die Schichtdicke des Gummiabriebs einmal vor der Laserablation und einmal nach der Laserablation bemessen wird. So kann der Erfolg der Reinigung nachverfolgt werden.According to embodiments of the invention, the cleaning vehicle comprises two ultrasonic transmitting devices and two ultrasonic measuring devices. This can be advantageous in that the layer thickness of the rubber abrasion is measured once before the laser ablation and once after the laser ablation. So the success of the cleaning can be traced.

Nach Ausführungsformen der Erfindung umfasst das Reinigungsfahrzeug zwei Laserquellen. Dies ist vorteilhaft, da der zweite Laser beispielsweise nach der zumindest einen Ultraschall-Messvorrichtung angeordnet sein kann. In diesem Fall wird eine zweite Ablation des Gummiabriebs durch den Laser vorgenommen, falls die zumindest eine Ultraschall-Messvorrichtung eine Schichtdicke des Gummiabriebs oberhalb eines Grenzwertes misst.According to embodiments of the invention, the cleaning vehicle comprises two laser sources. This is advantageous because the second laser can be arranged, for example, after the at least one ultrasonic measuring device. In this case, a second ablation of the rubber abrasion by the laser is performed if the at least one ultrasonic measuring device measures a layer thickness of the rubber abrasion above a limit value.

Nach Ausführungsformen der Erfindung umfasst das Reinigungsfahrzeug Mittel zum Empfang eines Signals eines Satelliten-Navigationssystems und eine robotische Steuerung. Die robotische Steuerung ist zur Steuerung des Reinigungsfahrzeugs unter Verwendung des Signals des Satelliten-Navigationssystems über die Landezone ausgebildet. In diesem Fall erfolgt die Reinigung der Landezone durch das Reinigungsfahrzeug voll automatisch. Das Signal des Satelliten-Navigationssystems kann beispielsweise mit einer Antenne für ein Global Positioning System-Signal oder ein Signal des Systems Galileo sein. Das Satelliten-Navigationssystemsignal wird an die robotische Steuerung ausgegeben. Außerdem hat die robotische Steuerung Zugriff auf einen Speicher, in dem die Koordinaten der Landezone gespeichert sind. Unter Verwendung der Daten der Landezone und des Satelliten-Navigationssystemsignals steuert die robotische Steuerung das Reinigungsfahrzeug so, dass die Landezone gereinigt wird.According to embodiments of the invention, the cleaning vehicle comprises means for receiving a signal of a satellite navigation system and a robotic control. The robotic controller is configured to control the cleaning vehicle using the signal of the satellite navigation system over the landing zone. In this case, cleaning of the landing zone by the cleaning vehicle is fully automatic. The signal of the satellite navigation system may be, for example, an antenna for a Global Positioning System signal or a signal of the Galileo system. The satellite navigation system signal is output to the robotic controller. In addition, the robotic control has access to a memory in which the coordinates of the landing zone are stored. Using the data of the landing zone and the satellite navigation system signal, the robotic control controls the cleaning vehicle to clean the landing zone.

Nach Ausführungsformen der Erfindung weist das Reinigungsfahrzeug Mittel zum Empfang eines Freigabesignals auf. Das Freigabesignal signalisiert hierbei eine Freigabe der Landezone. Die robotische Steuerung ist zur Verwendung des Freigabesignals zur Steuerung des Reinigungsfahrzeugs ausgebildet. Dies ist vorteilhaft, da so eine Reinigung der Landezone immer dann erfolgen kann, wenn die Landezone zur Reinigung freigegeben ist. Es ist hierbei nicht nötig, die Reinigung manuell zu initiieren. Durch Versendung des Freigabesignals wird die Reinigung automatisch initiiert.According to embodiments of the invention, the cleaning vehicle has means for receiving an enable signal. The enable signal signals a release of the landing zone. The robotic controller is configured to use the release signal to control the cleaning vehicle. This is advantageous because such a cleaning of the landing zone can always take place when the landing zone is released for cleaning. It is not necessary to initiate the cleaning manually. By sending the release signal, cleaning is initiated automatically.

Nach Ausführungsformen der Erfindung umfasst das Reinigungsfahrzeug eine Stromquelle zur Versorgung der Laserquelle mit elektrischer Energie und einen Verbrennungsmotor zum Antrieb des Fahrzeugs. Der Verbrennungsmotor ist hierbei dazu ausgebildet, die Stromquelle aufzuladen. Die Stromquelle kann beispielsweise eine Brennstoffzelle oder ein elektrischer Akkumulator sein.According to embodiments of the invention, the cleaning vehicle comprises a power source for supplying the laser source with electrical energy and an internal combustion engine for driving the vehicle. The internal combustion engine is in this case designed to charge the power source. The power source may be, for example, a fuel cell or an electric accumulator.

Nach Ausführungsformen der Erfindung weist das Reinigungsfahrzeug einen Verbrennungsmotor auf. Der Verbrennungsmotor ist zum Antrieb des Reinigungsfahrzeugs und zur Versorgung der Laserquelle mit elektrischer Energie ausgebildet. Mit anderen Worten treibt der Verbrennungsmotor das Fahrwerk oder zumindest einen Teil des Fahrwerks des Reinigungsfahrzeugs an. Zusätzlich wird durch den Betrieb des Verbrennungsmotors elektrische Energie erzeugt, die an die Laserquelle ausgegeben wird.According to embodiments of the invention, the cleaning vehicle has an internal combustion engine. The internal combustion engine is designed to drive the cleaning vehicle and to supply the laser source with electrical energy. In other words, the engine drives the landing gear or at least part of the landing gear of the cleaning vehicle. In addition, the operation of the internal combustion engine generates electrical energy that is output to the laser source.

Nach Ausführungsformen der Erfindung weist die Laserquelle eine Leistung von mehr als 100 W auf. Die ist vorteilhaft, damit der hochverdichtete Gummiabrieb im Bereich der Landezone verdampft werden kann.According to embodiments of the invention, the laser source has a power of more than 100W. This is advantageous so that the highly compressed rubber abrasion can be evaporated in the landing zone.

In einem weiteren Aspekt betrifft die Erfindung ein Verfahren zur Entfernung von auf einer Landezone einer Flugzeuglandebahn anhaftendem Gummiabrieb von Flugzeug reifen mit einem Laserstrahl.In a further aspect, the invention relates to a method for removing adhering to a landing zone of an aircraft runway rubber abrasion of aircraft tires with a laser beam.

Nach Ausführungsformen der Erfindung umfasst das Verfahren das Befahren der Landezone mit einem Reinigungsfahrzeug. Ein Laserstrahl wird während des Befahrens der Landezone mit einem für die Ablation von Gummi geeigneten Frequenzbereich erzeugt. Der Laserstrahl wird auf die Landezone gelenkt. Dies kann beispielsweise durch Lichtwellenleiter oder ein Spiegelsystem geschehen. Noch vor dem Auftreffen des Laserstrahls auf die Landezone wird der Laserstrahl aufgeweitet, sodass beim Befahren der Landezone der aufgeweitete Laserstrahl auf die Oberfläche der Landezone trifft. Das Aufweiten des Laserstrahls ist vorteilhaft, damit ein großer Bereich der Landezone von Gummiabrieb bereinigt wird. Durch das Auftreffen des Laserstrahls auf die Landezone folgt eine Ablation des Gummiabriebs durch den Laserstrahl.According to embodiments of the invention, the method comprises driving the landing zone with a cleaning vehicle. A laser beam is generated while traveling the landing zone with a frequency range suitable for the ablation of rubber. The laser beam is directed to the landing zone. This can be done for example by optical fibers or a mirror system. Even before the impact of the laser beam on the landing zone, the laser beam is widened so that when approaching the landing zone the expanded laser beam strikes the surface of the landing zone. The expansion of the laser beam is advantageous in order to clear a large area of the landing zone of rubber abrasion. The impact of the laser beam on the landing zone is followed by ablation of the rubber abrasion by the laser beam.

Nach Ausführungsformen der Erfindung umfasst das Verfahren das Messen einer ersten Schichtdicke des Gummiabriebs. Dies kann beispielsweise durch ein Ultraschall-Schichtdicken-Messverfahren geschehen. Bei der Ablation entstehende Dämpfe werden abgesaugt und gegebenenfalls gefiltert oder katalysiert. Eine zweite Schichtdicke des Gummiabriebs wird von einer zweiten Messvorrichtung nach der Ablation gemessen. Die erste und die zweite Schichtdicke können in einem Speicher gespeichert werden.According to embodiments of the invention, the method comprises measuring a first layer thickness of the rubber abrasion. This can be done for example by an ultrasonic layer thickness measurement method. Vapors produced during ablation are drawn off and, if necessary, filtered or catalyzed. A second layer thickness of the rubber abrasion is measured by a second measuring device after the ablation. The first and the second layer thicknesses can be stored in a memory.

Ausführungsformen der Erfindung sind vorteilhaft, da das kostenintensive, witterungsabhängige, abrasive, aufwendige und umweltschädliche Wasserhöchstdruck-Verfahren durch das kostensparende, witterungsunabhängige, einfache und umweltschonende Laserablationsverfahren ersetzt werden kann. Das Laserablationsverfahren kann auch durch die kostengünstigere und einfachere Durchführungsweise öfter durchgeführt werden als das Wasserhöchstdruck-Verfahren, sodass sich eine relativ konstante Qualität der Landezone bezüglich der Traktion der Flugzeugreifen ergibt. Es entsteht keinerlei Schmutzwasser, das entsorgt werden müsste. Die entstehenden Dämpfe können abgesaugt, gefiltert und/oder katalysiert werden. Dies macht das Laserablationsverfahren im Vergleich zum Wasserhöchstdruck-Verfahren außerordentlich umweltfreundlich.Embodiments of the invention are advantageous because the cost-intensive, weather-dependent, abrasive, complex and environmentally harmful high-pressure water process can be replaced by the cost-saving, weather-independent, simple and environmentally friendly laser ablation process. The laser ablation process may also be performed more often than the high-pressure water process by the more cost effective and simpler procedure, resulting in a relatively constant landing zone quality with respect to the traction of the aircraft tires. There is no waste water that needs to be disposed of. The resulting vapors can be sucked off, filtered and / or catalyzed. This makes the laser ablation process extremely environmentally friendly compared to the high pressure water process.

lm Weiteren werden zur Verdeutlichung von Ausführungsformen der Erfindung ein Reinigungsfahrzeug zur Reinigung einer Landezone einer Flugzeuglandebahn gezeigt. Es zeigt:

Figur 1
eine schematische Darstellung eines Reinigungsfahrzeugs zur Reinigung einer Landezone einer Flugzeuglandebahn.
In addition, to illustrate embodiments of the invention, a cleaning vehicle for cleaning a landing zone of an aircraft runway is shown. It shows:
FIG. 1
a schematic representation of a cleaning vehicle for cleaning a landing zone of an aircraft runway.

Figur 1 zeigt schematisch ein Reinigungsfahrzeug 100 zur Reinigung einer Landezone einer Flugzeuglandebahn. Das Reinigungsfahrzeug 100 weist ein Fahrwerk 102, eine Laserquelle 104, einen Strahlaufweiter 108, eine Absaugvorrichtung 110, eine Ultraschall-Aussende- und -Messvorrichtung 112, Stromquelle 114, Leitungen 116 und 118 und einen Motor 120 auf. FIG. 1 schematically shows a cleaning vehicle 100 for cleaning a landing zone of an aircraft runway. The cleaning vehicle 100 has a chassis 102, a laser source 104, a beam expander 108, a suction device 110, an ultrasonic transmission and measuring device 112, power source 114, lines 116 and 118 and a motor 120.

Im Betrieb wird das Reinigungsfahrzeug 100 durch den Motor 120 angetrieben. Das Reinigungsfahrzeug 100 bewegt sich mit dem Fahrwerk 102 über die Landezone der Flugzeuglandebahn. Die Laserquelle 104 erzeugt einen Laserstrahl 106, der durch hier nicht dargestellte Mittel zur Lenkung des Laserstrahls so gelenkt werden kann, dass er in Richtung der Landezone strahlt. Der Laserstrahl 106 wird durch den Strahlaufweiter 108 noch vor Auftreffen des Laserstrahls 106 auf die Landezone aufgeweitet. Hierdurch wird der Bereich der Säuberung vergrößert.In operation, the cleaning vehicle 100 is powered by the engine 120. The cleaning vehicle 100 moves with the landing gear 102 over the landing zone of the aircraft runway. The laser source 104 generates a laser beam 106, which can be directed by means not shown here for guiding the laser beam so that it radiates in the direction of the landing zone. The laser beam 106 is widened by the beam expander 108 before the laser beam 106 strikes the landing zone. This enlarges the area of the purge.

Wenn der Laserstrahl 106 auf die Landezone trifft, wird dort befindlicher Gummiabrieb von dem Laserstrahl so stark erhitzt, dass eine Ablation erfolgt. Die hierbei entstehenden Dämpfe werden durch die Absaugvorrichtung 110 abgesaugt und gegebenenfalls durch zusätzliche Filter und/oder Katalysatoren gefiltert und/oder katalysiert.When the laser beam 106 strikes the landing zone, rubber abrasion there is heated to such an extent by the laser beam that ablation occurs. The resulting vapors are sucked through the suction device 110 and optionally filtered and / or catalysed by additional filters and / or catalysts.

Die Ultraschall-Aussende- und -Messvorrichtung 112 sendet ein Ultraschallsignal aus und misst eine Reflektion des Ultraschallsignals durch die Landezone. Das Reflektionssignal wird durch die Messvorrichtung ausgewertet. Die Messvorrichtung errechnet aus dem reflektierten Ultraschallsignal eine Schichtdicke des Gummiabriebs. So kann kontrolliert werden, wie dick die Schichtdicke des Gummiabriebs nach der Ablation durch den Laser ist.The ultrasound emitting and measuring device 112 emits an ultrasound signal and measures a reflection of the ultrasound signal through the landing zone. The reflection signal is evaluated by the measuring device. The measuring device calculates a layer thickness of the rubber abrasion from the reflected ultrasonic signal. This makes it possible to check how thick the layer thickness of the rubber abrasion is after ablation by the laser.

Die Laserquelle 102 wird durch die Stromquelle 114 mit elektrischer Energie versorgt. Die Verbindung zwischen Laserquelle 104 und Stromquelle 114 erfolgt über Leitung 116. Über Leitungen 118 und 116 kann die Stromquelle durch den Motor 120 aufgeladen werden. Alternativ kann der Motor 120 die Laserquelle 104 direkt über die Leitung 118 mit elektrischer Energie versorgen.The laser source 102 is powered by the power source 114 with electrical energy. The connection between the laser source 104 and current source 114 via line 116. Via lines 118 and 116, the power source through the motor 120 charged. Alternatively, the motor 120 may provide the laser source 104 with electrical energy directly via the lead 118.
