Embodiment Construction

[0031] This embodiment is a reentry inflation system for spacecraft recovery. In the reentry process, the aerodynamic rudder surface formed by inflation is used to provide the recovered object with resistance for deceleration and torque for attitude control. At the same time, the trapezoidal aerodynamic rudder surface enlarges the mutual distance between the complex vortices in the wake area, thereby suppressing the irregular oscillation of the entire recovery system caused by the unsteady vortices.

[0032] This embodiment includes four rudder surfaces 1, a reduction cover 2, an instrument compartment 3, a payload compartment 4, an air compressor 6, and corresponding inflation and exhaust pipes and a micro control system. among them:

[0033] The deceleration cover is tapered and arranged around the payload compartment, and one end of the deceleration cover is connected to the lower end of the payload compartment 4, and is expanded toward the upper end of the payload compartment a...

Abstract

The invention provides a stability augmentation inflation type reentry vehicle. An umbrella-shaped inflation body is formed by an inflation type speed reduction cover and an instrument cabin. Four inflation type control surfaces are evenly distributed on the outer edge of the speed reduction cover. An air compressor and a control system are placed in an effective load cabin from bottom to top. A main valve of the air compressor is communicated with inflation openings of the control surfaces and inflation openings of the speed reduction cover through inflation pipelines respectively. In the stability augmentation inflation type reentry vehicle, the control surfaces and the speed reduction cover can be opened through an inflation device when used, and are put away after being used. The stability augmentation inflation type reentry vehicle is light in structural weight and convenient to design, machine, maintain, control and the like. Under the condition that the structure of the speed reduction cover does not need to be changed and no complex propelling systems need to be added, the aerodynamics characteristics required for control are obtained, the active control over the atmospheric reentry aircraft is achieved, and unsteady influences of complex eddy of the leeward area of the speed reduction cover on the posture of the reentry vehicle are avoided.

Description

Technical field [0001] The invention relates to the recovery field of modern aerospace vehicles, in particular to a stabilizing inflatable reentry aircraft. Background technique [0002] Spacecraft recovery technology is a comprehensive application technology involving multiple disciplines. In recent years, with the development and progress of the aerospace industry, the research on aerodynamic recovery technology has expanded from the traditional parachute technology field to flexible deployment. Type aerodynamic deceleration field. The most representative one is IRDT, an inflatable reentry and landing technology under study in Russia. With the help of European Space Agency (ESA), German DASA, Astrium and other companies, Russia has successfully developed an inflatable reentry system IRDT. The working characteristics of IRDT are: the IRDT cabin is folded by a high temperature resistant flexible braid and wrapped in a return type A heat shield is formed on the periphery of the ...
