Abstract

The invention discloses a motor and air pressure integrated driving aerospace vehicle deformation nose cone device which comprises three or more stages of nose cone shells, wherein the diameters of the nose cone shells are gradually increased from back to front; all the nose cone shells are connected through connection mechanisms; the rear end of the last stage of nose cone shell is hinged with athree-star ring; the previous two stages of nose cone shells comprise annular shell bodies; the interiors of the front ends of the annular shell bodies are connected with extension and retraction mechanisms and bending mechanisms. The motor and air pressure integrated driving aerospace vehicle deformation nose cone device can simulate deformation of the abdomen of honey to realize extension, retraction and deformation motions, so that extension and retraction motions of a nose cone can be realized, and a bending motion can be realized; the motor and air pressure integrated driving aerospace vehicle deformation nose cone device has the advantages of simple and convenient driving form, easy implementation of self-locking performance, modularity, simple mechanism form and convenience in machining and manufacturing.

Description

technical field [0001] The invention belongs to the technical field of aerospace vehicles, and in particular relates to a deformable nose cone device for aerospace vehicles which is comprehensively driven by a motor and air pressure. Background technique [0002] Spacecraft will be greatly affected by the environment during high-speed flight, and bees can reduce the impact by adjusting the tail and abdomen during flight. The aircraft deformation technology based on bionics research has emerged as the times require. However, the relevant deformation fields are mostly the deformation of the engine and the wing, and there are relatively few deformations for other parts, especially the deformation mechanism for the nose cone. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of the prior art, the purpose of the present invention is to provide a kind of deformable nose cone device of an aerospace vehicle containing a comprehensive drive of ...
