Embodiment Construction

[0031] This embodiment is a reentry inflation system for spacecraft recovery. During the reentry process, the aerodynamic rudder surface formed by inflation is used to provide the recovered object with resistance for deceleration and moment for attitude control. At the same time, the trapezoidal aerodynamic rudder surface increases the mutual distance between the complex eddies in the wake area, thereby suppressing the irregular swing phenomenon of the recovery system as a whole caused by the unsteady vortex.

[0032] The present embodiment comprises four rudder surfaces 1, a speed reduction cover 2, an instrument compartment 3, a payload compartment 4, an air compressor 6 and corresponding inflation and exhaust ducts and a micro control system. in:

[0033] The deceleration cover is conical, arranged around the payload compartment, and one end of the deceleration cover is communicated with the lower end of the payload compartment 4, and is deployed to the upper end of the pay...

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 field of recovery of modern aerospace vehicles, in particular to a stabilized inflatable reentry vehicle. 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 and deployable technology. Type aerodynamic deceleration field. The most representative is the inflatable reentry and landing technology IRDT that Russia is researching. With the help of European Space Agency (ESA), German DASA and Astrium and other companies, Russia has successfully developed the inflatable reentry system IRDT. The periphery of the aircraft forms a heat shield. The heat shield is inflated before entering the atmosphere, forming an inverted cone to wrap the returning aircr...
