摘要：
Double-guided deceleration parachute is widely used in large-scale space return activities. Compared with single-guided parachute, it has higher security, but its structure is more complex. This paper aims to study on line sail and analyse the effects of different initial dynamic pressure, separation speeds and angles of attack on the phenomenon during double-guided parachute deployment. The results show that for the double-guided parachute, the bigger the dynamic pressure of the return cabin is, the smaller the separation speed is, the bigger the angle of attack is, the more serious the line sail phenomenon will be.
