Abstract

The invention discloses a wing folding mechanism of a morphing aircraft, and belongs to the field of aircraft wing mechanisms. The problems that an existing wing folding mechanism is only used for ground folding, and a gap is formed between an inner wing section and an outer wing section in the folding process are solved. An inner side reinforcing rib is fixedly arranged on a wing beam of the inner wing section, an outer side reinforcing rib is fixedly arranged on a wing beam of the outer wing section, a rotary actuator is located between the inner side reinforcing rib and the outer side reinforcing rib, a fusiform fairing is composed of a fairing body and a sealing ring, and an inner side lug, the rotary actuator and the outer side lug are sealed inside the fusiform fairing. The connection end of the fairing body is connected to an outer frame of the inner side reinforcing rib in a sleeving mode, and the connection end of the sealing ring is connected to an outer frame of the outer side reinforcing rib in a sleeving mode. The wing mechanism is foldable.

Description

technical field [0001] The invention relates to a wing folding mechanism of a variant aircraft, and belongs to the field of wing mechanisms of aircraft. Background technique [0002] Wing folding can significantly change the wetted area of ​​the whole aircraft, which is a typical way for variant aircraft to change the shape of the aircraft. Especially in the case of supersonic speed, by folding the outer section of the wing downward at a certain angle, not only can the supersonic drag be greatly reduced, the directional stability can be enhanced, but also the air on the lower wing surface can be compressed to provide additional lift. Due to the above functions, the following conditions need to be met when designing the wing folding mechanism: (a) to realize the function of folding and unfolding of the wings during flight; (b) to ensure the aerodynamic and stealth performance of the aircraft, the folding and during the unfolding process, there should be no gap between the in...
