The parachuting release command and landing trajectory simulation system

In this paper, an algorithm model concluding resultant wind, magnetic heading and running time, and a system to simulate landing trajectory have built. The system has given real-time parameters of the static-line parachuting in headwind, draw plane projection trajectory, in situ three-dimensional landing trajectory of the static-line parachuting in headwind and simulated parachuting landing trajectory. The validity and practicality of the method are examined by application example. This algorithm improves the accuracy and the efficiency of parachuting release computing, increases the efficiency of parachuting command, and realizes the automating of parachuting command.
