Abstract

The invention provides a deformable missile wing and a flight device, and relates to the technical field of space flight and aviation. The deformation missile wing comprises a deformation driving mechanism and at least two layers of missile wings; one deformation driving mechanism is arranged between any two adjacent layers of missile wings, and the deformation driving mechanism is used for driving one layer of missile wing in the two adjacent layers of missile wings to move relative to the other layer of missile wing, so that the layer of missile wing is contained in the other layer of missile wing, or the layer of missile wing is unfolded relative to the other layer of missile wing. According to the deformable missile wing, complete recovery of the deformable missile wing is achieved, and space is saved. And when the device is applied to the flight device, the transportation and mounting space of the flight device is greatly improved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a deformable wing and a flying device. Background technique [0002] The deformable wings have the function of stretching and folding, and are widely used in aircraft such as missiles and aircraft carriers, which can reduce the space for aircraft transportation and mounting. Modern missiles are developing in the direction of high Mach number, high maneuverability, and ultra-long attack range. This requires that the overall aerodynamic shape of the missile be changed by changing parameters such as the airfoil shape, span length, chord length, and sweep angle of the missile, so that it can operate under different conditions. It can obtain better lift-to-drag ratio and aerodynamic characteristics at all flight speeds, enhance maneuverability, and improve combat capabilities. [0003] In the prior art, the deformed wings are usually folded and unfolded. When the deformed wings a...
