Abstract
Hauptanspruch 1. Leichtbau-Rahmenkonstruktion für Multikopterfluggeräte, dadurch gekennzeichnet, dass die Ausleger (2) mittels eines Zentralverbindungsstücks (1) verbunden sind und hierdurch alle einwirkenden Kräfte aufgenommen werden können. Nebenansprüche1. Lightweight frame construction for multi-copter aircraft, characterized in that the boom (2) by means of a central connector (1) are connected and thereby all acting forces can be absorbed. In addition to claims
Description
Stand der Technik:State of the art:
Vertikal startende und landende Fluggeräte (VTOL: Vertical Take-Off and Landing), wie die Fluggeräteform des Multicopters (Multirotor, Drohne), mit wahlweise 2, 3, 4, 6 oder 8 Rotoren, werden für die unterschiedlichsten Zwecke eingesetzt und besitzen eine zentrale Rahmenkonstruktion, welche der Montage und dem mechanischen Verbinden aller flugnotwendigen Bauteile dient. Diese Rahmenkonstruktion kann aus verschiedenen Materialzusammensetzungen bestehen und stellt einen nicht unerheblichen Anteil des Fluggeräte-Gesamtgewichts dar. Multicopter-Rahmenkonstruktionen bestehen meist aus CFK-Fertigbauteilen, welche in der Gesamtkonstruktion zusammengefügt werden.Vertically taking-off and landing vehicles (VTOL: Vertical Take-Off and Landing), such as the multicopter (multi-rotor, drone) aircraft, with optional 2, 3, 4, 6 or 8 rotors, are used for a variety of purposes and have a centralized Frame construction, which serves the assembly and the mechanical connection of all flight necessary components. This frame construction can consist of various material compositions and represents a not inconsiderable proportion of the total weight of the aircraft. Multicopter frame structures usually consist of prefabricated CFRP components which are assembled in the overall construction.
Durch den Gewichtsanteil der Rahmenkonstruktion am abflugfähigen Gesamtgerät wird die Flugzeit eines Multicopterfluggerätes stark beeinflusst bzw. beschränkt. Durch das Zusammensetzen vorkonfektionierter Rahmenbauteile kann nicht das Höchstmaß an Gewichts-Stabilitäts-Optimierung erreicht werden, da hierfür eine reine Vollbauweise der einzelnen Bauteile sowie verschiedene Verbindungsmechanismen verwendet werden.Due to the weight fraction of the frame construction on the overall aircraft, the flight time of a Multicopterfluggerätes is greatly affected or limited. By assembling prefabricated frame components, the highest degree of weight stability optimization can not be achieved since a pure full construction of the individual components and various connection mechanisms are used for this purpose.
Der Schutzanspruch umfasst die zentrale Verbindung verschiedener Rahmenbauteile, speziell den Auslegern, wobei durch ein Zentralverbindungsstück ein Minimum an Verbindungsstellen sowie die Leichtbauweise der gesamten Rahmenkonstruktion erreicht wird. Durch verschiedene Leichtbauaussparungen sowie extrem strapazierfähigen und leichten Konstruktionsmaterialien wie Kohlefaserverbundwerkstoff (CFK), wird ein Höchstmaß an Stabilität bei geringem Gewicht erreicht. Das Zusammenfügen verschiedener Rahmenbauteile führt indes mit Hilfe von extrem leichten Aluminium- oder Carbonschrauben zu einer weiteren Gewichtseinsparung. Im Detail umfasst der Schutzanspruch folgende Punkte: The protection claim comprises the central connection of various frame members, especially the jibs, wherein a minimum of joints and the lightweight construction of the entire frame construction is achieved by a central connector. Through various lightweight recesses and extremely durable and lightweight construction materials such as carbon fiber composite (CFRP), the highest degree of stability is achieved with low weight. The assembly of different frame components leads meanwhile with the help of extremely light aluminum or carbon screws to a further weight saving. In detail, the protection claim includes the following points:
