Abstract

The invention relates to the field of spaceflight and discloses a controllably and orderly inflated self-supporting type solar sail structure. A sail surface approximately triangle-shaped and formed by three curves is adopted, the sail surface can be unfolded in orbit stably and orderly, and distribution gradient of internal plane stress forced on the sail surface after unfolding is reduced by 20%; a support ring with the inner diameter equal to a winding shaft is arranged at the position of rectangular vertice of the sail surface, and concentrated stress of the sail surface can be lowered; a circular opening enclosed by 4n (n is larger than or equal to 3, and n is an integer) sawteeth, and no relative movement between the vertice of the sail surface and the winding shaft can be guaranteed; four sets of inflated extension arms used for supporting the sail surface are unfolded, each set is formed by two extension arms, straightness of the inflated extension arms and rigidity of the inflated extension arms after being unfolded can be improved, the rigidity of the structure is two times of that of a structure with a single extension arm, and unfolding stability of the extension arms is improved.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to a self-supporting solar sail structure that can be inflated and deployed in a controllable and orderly manner. Background technique [0002] After entering the 21st century, the field of deep space exploration has been paid more and more attention by human beings. As a new type of aircraft, the solar sail spacecraft can realize the accelerated motion of the aircraft without a propulsion system. The solar sail aircraft obtains flight power through the momentum exchange with the sun photons. And this propulsion resource is endless, and the propulsion sustaining force only depends on the life span of the solar sail film and the actuator and the distance from the light source. It has high research value in the field of deep space exploration. In order to provide enough propulsion for the spacecraft, the spacecraft needs a sufficiently large solar sail surface. The inflatable deployable so...
