Description
Die vorliegende Erfindung betrifft eine Luftfahrzeugstrukur sowie ein senkrecht start- und landefähiges (vertical take-off and landing, VTOL) Luftfahrzeug mit einer solchen Luftfahrzeugstruktur.The present invention relates to an aircraft structure and a vertical take-off and landing (VTOL) aircraft with such an aircraft structure.
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 the term used across all languages to describe any type of aircraft, drone or rocket that has the ability to take off and land essentially vertically and without a runway. This collective term is used in the following in a broad sense, which includes not only fixed-wing aircraft with wings, but also rotary-wing aircraft such as helicopters, gyroplanes, flight helicopters and hybrids such as compound helicopters or combination helicopters as well as convertible aircraft. It also includes aircraft with the ability to take off and land over particularly short distances (short take-off and landing, STOL), take off over 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).
Ein senkrecht startendes und landendes Flugzeug gemäß
Der Grundgedanke einer bevorzugten Ausführungsform ist hierbei die Verwendung eines relativ zur Nutzlastkabine schwenkbaren Rahmens zur Auftriebserzeugung im Vorwärtsflug.The basic idea of a preferred embodiment is the use of a frame that can be pivoted relative to the payload cabin to generate lift in forward flight.
Ein Vorzug dieser Lösung liegt primär in ihrer Eignung, die mögliche Maximalgeschwindigkeit deutlich zu erhöhen durch Verlagerung der Auftriebserzeugung von den Hubantrieben maßgeblich zu Strukturbauteilen des Fluggeräts. Dabei ist die zur Verfügung stehende Schubleistung der Antriebe hauptanteilig in Flugrichtung aufzubringen, nicht entgegen der nach unten gerichteten Gewichtskraft. Der Auftrieb wird im Vorwärtsflug hauptsächlich durch die relativ zur Anströmung optimiert angestellten Anteile der vorzugsweise aus Rahmen, Antriebsgehäuse und Nutzlastkabine bestehenden Luftfahrzeugstruktur erzeugt. Gleichzeitig wird der Luftwiderstand des Gesamtsystems durch eine günstige Bauteilausrichtung reduziert und damit eine höhere Maximalgeschwindigkeit möglich.One advantage of this solution lies primarily in its ability to significantly increase the maximum possible speed by shifting the lift generation from the lifting drives to the structural components of the aircraft. The available thrust of the drives to be applied mainly in the direction of flight, not against the downward force of gravity. In forward flight, the lift is generated mainly by the parts of the aircraft structure, which preferably consist of the frame, drive housing and payload cabin, which are positioned in an optimized manner relative to the airflow. At the same time, the air resistance of the entire system is reduced by a favorable component alignment, thus making a higher maximum speed possible.
