Take-off device for ornithopter

Abstract

The invention belongs to the technical field of aviation engineering, and particularly discloses a take-off device for an ornithopter. The take-off device comprises a transverse cable, two pulley components, and two drum components driven by outer rotor motors; the two pulley components and the two drum components are arranged in symmetry relative an airport runway; the transverse cable is sequentially wound around one drum component, the fixed pulley component on the same side, the fixed pulley component on the opposite side and the other drum component on the opposite side. The transverse cable crosses the airport runway, and the drum components are driven by the outer rotor motors. During take-off, the transverse cable is pulled by a towing vehicle to be hung on a padlock mechanism at the front end of the ornithopter, an ornithopter engine and the outer rotor motors are cooperatively started to assist the take-off, and the outer rotor motors help provide the initial speed of the ornithopter, so that the stability of the ornithopter is enhanced, the sliding distance of the ornithopter is shortened, and an ornithopter runway is shortened; by the design of the pulley components, the take-off direction can be selected according to the actual wind direction; through electric power assisted dragging, the fuel consumption is reduced, and the surrounding environmental pollution of an airport is reduced.

Description

technical field [0001] The invention belongs to the technical field of aeronautical engineering, and in particular relates to an airfield power-assisted take-off device for a flapping wing aircraft. Background technique [0002] At present, orptopters take off at home and abroad all adopt orptopter airport runways, which mainly have the following disadvantages: Due to the direct take-off of the orthopter, a large amount of fuel will be consumed and the surrounding environment will be polluted; When the orthopter takes off, the initial speed of the orthopter is lower than that of the fixed-wing aircraft. The crosswind at the airport will easily cause the flight stability of the orthopter, making it difficult to take off. Contents of the invention [0003] In order to solve the technical problems existing in the prior art, the present invention provides an airport-assisted take-off device for a flapper aircraft driven by an external rotor motor, which can reduce fuel cons...
