Air-injection reversing mechanism of aircraft

Abstract

The invention relates to an air-injection reversing mechanism of an aircraft. One or more reversing mechanism is installed on a fuselage of the aircraft. The reversing mechanism comprises a reversing base and a plurality of flow guide plates. Each flow guide plate is provided with a fulcrum and installed below an air inlet of the reversing base through the fulcrum. All the flow guide plates are connected through connecting rods so as to be in linkage. A propeller is installed at the air inlet of the reversing base, and tail jet nozzles are arranged on the lower portion and the tail of the reversing base correspondingly. The air-injection reversing mechanism of the aircraft has the beneficial effects that firstly, the reversing mechanism is simple and reliable, and the implementation cost is low; secondly, the reversing angle range is wide and can theoretically reach 180 degrees; thirdly, the reversing speed is adjustable, the requirement for rapid reversing can be met, and it is actually measured that reversing by 90 degrees can be completed in 0.5 second; and fourthly, the torque requirement required by reversing is extremely low, and theoretically, as long as the effect that the sum of the projection areas, on the left side, of the fulcrums of all the flow guide plates is the same as the sum of the projection areas, on the right side, of the fulcrums of all the flow guide plates is guaranteed, no extra force is needed for maintaining the whole reversing mechanism.

Description

technical field [0001] The invention belongs to the technical field of jet reversing mechanisms, and in particular relates to a jet reversing mechanism used for aircraft on equipment such as model airplanes or unmanned aerial vehicles. Background technique [0002] The current mainstream aircraft industry, especially the UAV industry, is mainly divided into two types: multi-rotor and fixed-wing. [0003] The advantage of a multi-rotor is that it can take off and land anywhere close to the level without a runway, but its flight principle determines that the aircraft is inefficient, its flight time is short, and its activity radius is small. [0004] The efficiency of fixed-wing aircraft is much higher than that of multi-rotors, but it must take off and land on the runway, which greatly limits the scope of application of this type of flight. Contents of the invention [0005] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide ...
