Abstract
Die Erfindung stellt einen Mantelpropeller (10) mit den folgenden Merkmalen bereit: Der Mantelpropeller (10) umfasst einen Elektromotor (12) mit einem Ständer (11) und einem Läufer; der Mantelpropeller (10) umfasst einen drehstarr mit dem Läufer verbundenen Rotor (13); und der Ständer (11) lagert den Rotor (13). The invention provides a jacket propeller (10) with the following features: the jacket propeller (10) comprises an electric motor (12) with a stator (11) and a rotor; the jacketed propeller (10) comprises a rotor (13) connected to the rotor in a torsionally rigid manner; and the stand (11) supports the rotor (13).
Description
Die vorliegende Erfindung betrifft einen 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.
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). Bekannte VTOL-Luftfahrzeuge bedienen sich unterschiedlichster Antriebsarten.In the aerospace industry, VTOL refers to any type of aircraft, drone or rocket that has the ability to take off and put back on essentially vertically and without a runway. This collective term is used in a broad sense below, which includes not only fixed-wing aircraft with wings, but also rotary-wing aircraft such as helicopters, gyroplanes, flight screwdrivers and hybrids such as compound helicopters or combination screwdrivers and convertible aircraft. Also included are aircraft with the ability to take off and land on particularly short distances (short take-off and landing, STOL), take off on short distances but land vertically (short take-off and vertical landing, STOVL). or take off vertically, but land horizontally (vertical take-off and horizontal landing, VTHL). Known VTOL aircraft use a wide variety of propulsion types.
Ein Hochgeschwindigkeits-Zentrifugalkompressor zum Komprimieren von Fluiden gemäß
Die Erfindung stellt einen Mantelpropeller (ducted fan) sowie ein - insbesondere vollelektrisches, im obigen Sinne senkrecht start- und landefähiges - Luftfahrzeug gemäß den unabhängigen Ansprüchen bereit.The invention provides a ducted fan and a - in particular fully electric, vertically launchable and landable in the above sense - aircraft according to the independent claims.
Ein Vorzug dieser Lösung liegt in der gegenüber herkömmlichen Mantelpropellern erzielbaren Gewichts- und Kostenreduktion. Für die Umsetzung wird dabei ein besonders kurzer Bauraum benötigt.One advantage of this solution is the weight and cost reduction that can be achieved compared to conventional jacketed propellers. A particularly short installation space is required for the implementation.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben. So 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.Further advantageous refinements of the invention are specified in the dependent claims. For example, the aircraft can be equipped with kinked or even optionally kinkable wings. A corresponding variant increases the wing area effective in horizontal flight, but without extending the footprint 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 quickly chargeable battery system which provides the drive energy for vertical take-off and landing as well as horizontal flight and enables the aircraft to be charged at short notice when stationary.
Zum Antrieb des Luftfahrzeuges können hierbei mehrere Mantelpropeller 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 propel the aircraft, several jacketed propellers of different sizes can also be used, as are known apart from aeronautical engineering, for example from hovercraft or sump boats. In such an embodiment, the cylindrical housing surrounding the propeller can considerably reduce the thrust losses due to turbulence at the blade tips. Suitable jacketed propellers may be aligned horizontally or vertically, designed to be pivotable between the two positions, or covered in horizontal flight by louvers for aerodynamic reasons. In addition, pure horizontal thrust generation by means of fixed jacket 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 preferably fully autonomous operation of the aircraft - with sufficient qualification, manual control can also be given to the human pilot, which gives the device according to the invention the greatest possible flexibility in handling.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.
Die Figur zeigt einen Längsschnitt des Mantelpropellers eines Luftfahrzeuges.The figure shows a longitudinal section of the jacket propeller of an aircraft.
Die einzige Figur illustriert die konstruktiven Merkmale einer bevorzugten Ausgestaltung des erfindungsgemäßen Mantelpropellers (
Der abgebildete Mantelpropeller (
Wie der Zeichnung unschwer zu entnehmen ist, erfordert diese bauliche Integration des Antriebsmotors und des Schubrotors nur wenige Bauteile. Eine Motorkühlung wird hierbei entweder durch einen ausreichenden Luftdurchlass oder anderweitige Kühlmedien gewährleistet.As can easily be seen from the drawing, this structural integration of the drive motor and the thrust rotor requires only a few components. Engine cooling is ensured either by sufficient air passage or other cooling media.
