Abstract

The invention provides a variant flexible tail edge structure based on a bionic conception, and belongs to the technical field of variant aircraft. The variant flexible tail edge structure provided by the invention is characterized in that an elastic base plate is arranged between a first flexible honeycomb and a second flexible honeycomb, a first air-operated muscle driver is arranged at the outer side of the first flexible honeycomb, and a first large transformation skin is arranged at the outer side of the first air-operated muscle driver; a second air-operated muscle driver is arranged at the outer side of the second flexible honeycomb, and a second large transformation skin is arranged at the outer side of the second air-operated muscle driver; a fracture surface combined by the first flexible honeycomb and the second flexible honeycomb is a put-down trapezoid, and a tail edge rigidity section is connected with an upper bottom of the trapezoid. The variant flexible tail edge structure provided by the invention realizes the driving / transformation / bearing integrated design, realizes the driving transformation of a flexible tail edge, and simplifies the tail edge structure. The variant flexible tail edge structure provided by the invention has the advantages that structure is simple, the weight is light, the driving / transformation / bearing are integrative.

Description

technical field [0001] The invention relates to a variant flexible trailing edge structure based on a bionic concept, and belongs to the technical field of variant aircraft. Background technique [0002] Since ancient times, nature has been the source of various technical ideas, engineering principles and major inventions of human beings. The invention of the airplane was inspired by human observation of the flight of birds. In 1903, the Wright brothers designed the world's first manned powered airplane. After more than a century of development, the comprehensive performance of modern aircraft has been greatly improved. However, most of the aircraft's control surfaces (such as ailerons, rudders, and elevators) and increasing lift devices (such as trailing edge flaps) are mostly hinged structures, which cannot be deformed as smoothly as bird wings, and the result is that the wing surface is damaged. smoothness and continuity. [0003] To this end, a variant flexible trail...
