Deformable nose cone for aircraft and aircraft having the same

Abstract

The invention discloses a deformable nose cone used for an air vehicle and the air vehicle comprising the same. The deformable nose cone comprises a plurality of annular body segments, a telescopic mechanism, at least one elastic supporting mechanism and at least one bending mechanism. The telescopic mechanism is connected with the multiple annular body segments and can stretch out and draw back in the front-back direction so that every two adjacent annular body segments can move relatively in the axial direction. Each elastic supporting mechanism is connected between the two corresponding adjacent annular body segments and is suitable for limiting the relative motion of the annular body segments in the axial direction and normally driving the annular body segments to move to straight positions. Each bending mechanism is arranged between the two corresponding adjacent annular body segments, and each bending mechanism and the corresponding elastic supporting mechanism are arranged at the two radial ends of the corresponding annular body segment correspondingly. The bending mechanisms can bend and deform when the telescopic mechanism stretches out and draws back so as to drive the annular body segments to move between the straight positions and the bent positions. According to the deformable nose cone disclosed by the embodiment of the invention, telescoping, bending and deforming can be achieved, and the deformable nose cone has the advantages of being simple and stable in structure, short in deforming time, adjustable in deforming amount, precise in deforming control and the like.

Description

technical field [0001] The invention relates to the field of aerospace technology, and more particularly, to a deformable nose cone for an aircraft and an aircraft with the same. Background technique [0002] An aerospace vehicle is a new type of aircraft that has both the functions of an aircraft and a spacecraft. During the flight, the aerospace vehicle needs to experience the environmental changes of flying in the atmosphere and space, and re-entering the atmosphere. At each stage, there are different requirements for the aerodynamic layout of its structure. It is the future development direction of the aerospace vehicle structure to design the aerospace morphing vehicle so that it can realize the variable aerodynamic configuration autonomously. To realize the variable structure of the aerospace vehicle, it can be carried out from the nose cone, wing leading edge, swept wing and other parts. If the nose cone has a variable body structure function, it is possible to impr...
