The Application of Horizontal-reentry Recovery Technology to Micro-gravity Scientific Research Rocket
Stage with experiment samples is called experiment stage which will reentry and recover safely, this part can be recycled by horizontal-reentry style. To speak particularly, when the experiment stage accomplishes the mission, before entering the aerosphere, Attitude Control Power System adjusts it to high attack, angle attitude, then experiment stage begins revolving about its axis after the attitude control completed, because revolving movement prevents the experiment stage from over-hot. There is no more attitude control after the experiment stage enters the aerosphere, aerodynamic force will keep attitude of the big angle of attack, maximizing the resistance, so that the experiment stage can decelerate rapidly. During the process of reentry, Inertial Measurement Unit measures the attitude, altitude, velocity parameters real time, once satisfying the condition of opening parachute, the parachute opening signal will be sent out, and the drogue and main parachute opens in turn, thus the experiment stage can be recovered safely.
