Abstract

The invention belongs to the field of aircraft, and specifically discloses a bionic folding wing based on 4D printing and its preparation method and application. The folding wing sheath of the bionic folding wing is connected with the bionic flapping wing skeleton, which is used to protect and store the bionic folding wing in a folded state. The flapping wing skeleton can be stretched and folded according to the temperature of the water in the water circulation flow channel. The water circulation control system is connected with the water circulation flow channel to control the temperature of the water in the water circulation flow channel. The flapping wing film covers the surface of the bionic flapping wing skeleton. The bionic folding wing based on 4D printing provided by the present invention can ensure that the bionic folding wing has a great folding rate, and at the same time only need the water circulation control system to adjust the temperature of the water in the water circulation channel to realize the unfolding and folding of the bionic folding wing, which can avoid Using a cumbersome mechanical structure, it has the advantages of simplicity, high efficiency, high mobility, and intelligence.

Description

technical field [0001] The invention belongs to the field of aircraft, and more specifically relates to a bionic folding wing based on 4D printing and its preparation method and application. Background technique [0002] Small-sized flapping-wing aircraft will occupy a pivotal position no matter in the military field or in the civilian field. Taking the military field as an example, the use of small flapping-wing aircraft to quickly and secretly sneak into enemy positions, carry out intelligence theft, and quickly maneuver to destroy important enemy facilities (such as arsenals, important strategic electronic equipment, etc.), can cause fatal blows to the enemy. [0003] For the design and manufacture of small flapping wing aircraft, the flapping wing is its key structure. Yet the flapping wing of present small-sized flapping wing aircraft has loaded down with trivial details structure, and folding rate is low, and manufacturing method is complicated. How to design an effi...
