Abstract
Die Erfindung stellt ein Luftfahrzeug (10) mit den folgenden Merkmalen bereit: Das Luftfahrzeug (10) umfasst mindestens einen Rotor (12) und eine Beleuchtung (11), derart konfiguriert, dass auf dem in Drehung befindlichen Rotor (12) eine Botschaft (13) erscheint.The invention provides an aircraft (10) with the following features: The aircraft (10) comprises at least one rotor (12) and lighting (11), configured in such a way that a message (13 ) appears.
Description
Die vorliegende Erfindung betrifft ein Luftfahrzeug, insbesondere ein vollelektrisches, senkrecht start- und landefähiges (vertical take-off and landing, VTOL) Luftfahrzeug.The present invention relates to an aircraft, in particular a fully electric, vertical take-off and landing (VTOL) aircraft.
Stand der TechnikState of the art
Als VTOL wird in der Luft- und Raumfahrttechnik sprachübergreifend jedwede Art von Flugzeug, Drohne oder Rakete bezeichnet, welche die Fähigkeit besitzt, im Wesentlichen senkrecht und ohne Start- und Landebahn abzuheben und wieder aufzusetzen. Dieser Sammelbegriff wird nachfolgend in einem weiten Sinne verwendet, der nicht nur Starrflügelflugzeuge mit Tragflächen, sondern ebenso Drehflügler wie Hub-, Trag-, Flugschrauber und Hybride wie Verbundhub- oder Kombinationsschrauber sowie Wandelflugzeuge einschließt. Erfasst seien des Weiteren Luftfahrzeuge mit der Fähigkeit, auf besonders kurzen Strecken zu starten und zu landen (short take-off and landing, STOL), auf kurzen Strecken zu starten, aber senkrecht zu landen (short take-off and vertical landing, STOVL) oder senkrecht zu starten, aber horizontal zu landen (vertical take-off and horizontal landing, VTHL).In aerospace engineering, VTOL is any type of aircraft, drone or rocket that has the ability to take off and touch down essentially vertically and without a runway. This collective term is used in a broad sense in the following, which includes not only fixed-wing aircraft with wings, but also rotary-wing aircraft such as helicopters, gyroscopes, aircraft helicopters and hybrids such as composite helicopters or combination helicopters as well as convertible aircraft. Aircraft with the ability to take off and land on particularly short routes (short take-off and landing, STOL), take off on short routes but land vertically (short take-off and vertical landing, STOVL) are also included. or take off vertically but land horizontally (vertical take-off and horizontal landing, VTHL).
In Verbindung mit unbemannten Drohnen ist es grundsätzlich bekannt, dass im Bereich der Rotoren angeordnete Lichtquellen zur Informationsdarstellung genutzt werden können. Hierzu sei beispielhaft auf die Schriften
Offenbarung der ErfindungDisclosure of the invention
Die Erfindung stellt ein Luftfahrzeug, insbesondere ein vollelektrisches, im obigen Sinne senkrecht start- und landefähiges Luftfahrzeug gemäß dem unabhängigen Anspruch 1 bereit.The invention provides an aircraft, in particular a fully electric aircraft capable of taking off and landing vertically in the above sense, according to independent claim 1.
Ein Vorzug dieser Lösung liegt in der erfindungsgemäß eröffneten Möglichkeit, sich drehende Rotoren durch aktive oder passive Beleuchtung dazu zu nutzen, für Dritte sichtbare Botschaften zu tragen. Dies kann von der Erteilung von Warnhinweisen (z. B. „keep clear“ bei geplanter Landung, „turn right“ bei Richtungswechsel usw.) über eine Kennzeichnung der Rotorkreise im Hinblick auf den einzuhaltenden Sicherheitsabstand bis hin zur Darstellung von Werbung dienlich sein.An advantage of this solution lies in the possibility opened up according to the invention of using rotating rotors by means of active or passive lighting to carry messages that are visible to third parties. This can be useful from issuing warning notices (e.g. “keep clear” when landing, “turn right” when changing direction, etc.) to marking the rotor circles with regard to the safety distance to be observed and displaying advertising.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben. So könnte gerade bei frei drehenden Rotoren ohne Mantel die optische Kennzeichnung der Blattspitzen ein vorteilhaftes Sicherheitsmerkmal darstellen.Further advantageous refinements of the invention are specified in the dependent claims. For example, in the case of freely rotating rotors without a casing, the optical marking of the blade tips could represent an advantageous safety feature.
Darüber hinaus kann das Luftfahrzeug etwa mit abgeknickten oder gar wahlweise abknickbaren Tragflächen ausgestattet sein. Eine entsprechende Variante vergrößert die im Horizontalflug wirksame Flügelfläche, ohne aber die Standfläche des Luftfahrzeuges auszudehnen.In addition, the aircraft can be equipped, for example, with angled or even optionally angled wings. A corresponding variant increases the wing area effective in level flight, but without expanding the standing area of the aircraft.
Ferner mag das Luftfahrzeug über ein schnell ladbares Batteriesystem verfügen, welches die Antriebsenergie für Senkrechtstart und -landung sowie Horizontalflug bereitstellt und eine kurzfristige Aufladung des Luftfahrzeuges im Stand ermöglicht.Furthermore, the aircraft may have a battery system that can be charged quickly, which provides the drive energy for vertical take-off and landing as well as level flight and enables the aircraft to be charged at short notice when the vehicle is stationary.
Zum Antrieb des Luftfahrzeuges können hierbei anstelle freifahrender Rotoren mehrere Mantelpropeller (ducted fans) auch unterschiedlicher Größe zum Einsatz kommen, wie sie abseits der Luftfahrttechnik etwa von Luftkissenfahrzeugen oder Sumpfbooten bekannt sind. Das den Propeller umgebende zylindrische Gehäuse vermag in einer derartigen Ausführungsform die Schubverluste infolge von Verwirbelungen an den Blattspitzen beträchtlich zu reduzieren. Geeignete Mantelpropeller mögen horizontal oder vertikal ausgerichtet, zwischen beiden Stellungen schwenkbar ausgeführt oder aus aerodynamischen Gründen im Horizontalflug durch Lamellen (louvers) abgedeckt sein. Zudem ist eine reine Horizontalschuberzeugung mittels feststehender Mantelpropeller denkbar.To drive the aircraft, instead of free-moving rotors, several ducted fans, also of different sizes, can be used, as they are known from air-cushion vehicles or swamp boats, for example. In such an embodiment, the cylindrical housing surrounding the propeller is able to considerably reduce the thrust losses due to turbulence at the blade tips. Suitable ducted propellers may be aligned horizontally or vertically, designed to be pivotable between the two positions or, for aerodynamic reasons, be covered by louvers in horizontal flight. In addition, a pure horizontal thrust generation by means of fixed ducted propellers is conceivable.
Schließlich kommt - neben einem vorzugsweise vollautonomen Betrieb des Luftfahrzeuges - bei hinreichender Qualifikation auch die Einräumung einer manuellen Kontrolle an den menschlichen Piloten in Betracht, was der erfindungsgemäßen Vorrichtung eine größtmögliche Flexibilität in der Handhabung verleiht.Finally - in addition to a preferably fully autonomous operation of the aircraft - with sufficient qualification, the granting of manual control to the human pilot comes into consideration, which gives the device according to the invention the greatest possible flexibility in handling.
