Abstract
The mass-spring damper model is used to analyze the effect factors on drag parachute deployment,including resistance area,elastic modulus and diameter of the parachute system,etc.Results show that drag parachute duration and the maximum falling distance decrease with the increase of deploy velocity.But system tension becomes larger by increasing the deploy velocity (200-300 km/h).Both the increase of pilot chute resistance area and the decrease of parachute system linear density can decrease the deployment duration and the maximum falling distances obviously.The effects on the trajectory of deployment,caused by elastic modulus and diameter of parachute system are insignificant.The key factors affecting drag parachute deployment are resistance area of pilot chute,deploy velocity and linear density of parachute system.Results provide analytical basis for engineering design of drag parachute system in aerospace industry.关键词
