Analysis for initial status parameters of parachute aircraft

Transformation from bullet to aircraft is the key technology for parachute aircraft. The transformation occurs at the end of initial bullet trajectory, so the simulation of trajectory can help us to analysis the affect factors. Contrast with tradition trajectory, the initial trajectory of parachute aircraft contains three phases: launch inside trajectory, free-control trajectory and parachuting trajectory. This work adds parachuting model into tradition trajectory model, and built simulation model on computer. Furthermore, to confirm the effect from parachute area and time of unfolding parachute, analysis for falling speed and time of stability (attack angle and roll) are made, and then the relates among these factors are summarized.
