Foldable bionic flapping wing aircraft

Abstract

The invention discloses a foldable bionic flapping wing aircraft which comprises a fuselage and wings, and further comprises a telescopic piece. The wing folding mechanisms are symmetrically arrangedat the two sides of the telescopic piece and comprise a connecting rod, one end of the connecting rod is connected with a transmission rod, and the end, away from the connecting rod, of the transmission rod is fixedly connected with a supporting column. The foldable bionic flapping wing aircraft also comprises a guide column, the transmission rod movably sleeves the guiding column, and a containing cavity is formed at the upper end of the supporting column. A circular ring is slidably connected into the containing cavity, a rotating shaft is connected to the inner wall of the circular ring, and the wings movably sleeve the rotating shaft. The foldable bionic flapping wing aircraft also comprises a wing folding mechanism, and the wing folding mechanism comprises a four-connecting rod mechanism formed by an input rod, a first connecting rod, an output rod and a second connecting rod. The foldable bionic flapping wing aircraft also comprises a cross-shaped rod piece, a sliding blind holeis arranged at the upper end of the cross-shaped rod piece, and an adjusting rod is connected into the sliding blind hole slidably. According to the scheme, the wings can be effectively folded on thefuselage, so that the wings are prevented from being abraded and damaged by external factors, and the utilization rate of the storage space is increased.

Description

technical field [0001] The invention relates to the technical field of micro-aircraft, in particular to a foldable bionic flapping-wing aircraft. Background technique [0002] Since the end of the last century, the aircraft has developed rapidly, especially the common fixed-wing aircraft and rotary-wing aircraft technology has become more and more mature, and began to develop towards civilian use, which has triggered a boom in the use of aircraft in recent years. At the same time, because traditional aircraft have too many scene limitations and functional defects, flapping-wing aircraft has also begun to develop rapidly. [0003] Flapping wing is an important structure of a new type of aircraft designed and manufactured based on the principle of bionics to imitate the flight of birds and insects. If this type of aircraft is successfully developed, it will have unique advantages compared with fixed-wing and rotary-wing flight: Such as taking off in situ or small venues, exce...

AI Technical Summary

Problems solved by technology

[0005] However, compared with fixed-wing and rotary-wing aircraft, the traditional flapping-wing aircraft has made great progress in flexibility and maneuverability, but it is still not close to the flying attitude of real creatures. Traditional flapping-wing aircraft have no way to adjust the wings in the air. The sensitivity needs to be improved for flying postures such as dive and side flight. At the same time, the flapping wing aircraft mainly includes the fuselage and wings. If the direction of the fuselage is regarded as the vertical space, then the direction of the wings is the horizontal space. Due to the needs of flight, the space span occupied by the wings in the lateral direction is relatively large, and the wings are relatively fragile. When in a non-working flight state, the wings are easily worn and damaged by external unpredictable factors. At the same time, during storage and transportation In the middle, the utilization rate of the storage space is low, and the wings are also easily damaged
