Abstract

The invention discloses a detent force umbrella for reentry deceleration of a reentry capsule, comprising plasma collecting electrodes arranged in the front and back of the reentry capsule, and multiturn coils arranged on wall of the reentry capsule, wherein the plasma collecting electrodes are electrically connected with two ends of the multiturn coils; the multiturn coils are uniformly arranged around the wall of the reentry capsule; two collecting electrodes are electrically charged in an unequal manner; the voltage difference caused by the unequal charge enables the multiturn coils to produce current and produce magnetic dipole magnetic field around the reentry capsule after being energized; the ions having an inclined angle between the incidence direction and the dipole magnetic field change movement direction; and some ions are reflected by the magnetic field so as to provide extra resistance for the reentry capsule. The detent force umbrella disclosed by the invention can make full use of plasmas around the reentry capsule during high-speed reentry of the reentry capsule to decelerate, further improve deceleration efficiency of the reentry section of the reentry capsule, reduce control difficulty and risk of the landing section of the reentry capsule, and provide a new technical support for safe and accurate landing of the reentry capsule of the Shenzhou spacecraft.

Description

Technical field [0001] The invention belongs to the application field of magnetic technology for the return capsule of a spacecraft to return to the ground, and in particular relates to a magnetic device used for deceleration of the return capsule reentry. Background technique [0002] When the Shenzhou spacecraft returns to the cabin, it needs to pass through the atmosphere again and return to the ground. The process of entering the atmosphere when the return module returns is called "reentry". After re-entering the atmosphere (about 10km altitude), the return module opens the parachute and landed to the ground. [0003] Due to the high speed of the return capsule in orbit, the low-Earth orbit speed of 200km / 300km is about 7.6km / s. Some special engineering methods must be adopted to decelerate the return capsule to re-enter the atmosphere at a slower speed. . At present, the method used for reentry of the return capsule is the high-speed reentry method. This method first uses t...
