某型直升机跳伞安全性研究

Investigation About Security of Parachute Jump from a Helicopter

本文介绍了直升机用于跳伞飞行的一种改装技术,文中应用运动学、直升机空气动力学计算方法,对某型直升机用于跳伞飞行进行了安全性分析研究,分析了从侧门和尾门跳伞的利弊,建立了某型机尾门跳伞时的运动学模型,分析了无尾门飞行的气动特性,计算和分析了某型机的操纵性和稳定性,为解决某型直升机跳伞存在的技术问题提供了理论支持。

This paper introduced a refitting technology for parachute from helicopter,By the way of kinematics and helicopter aerodynamics,Analysed it's security and advantages and disadvantages jump from side door and tail door,and then found a kinematics model and analysed aerodynamic characteristic,and calculated handling and stability characteristics when bailing out from tail door in a helicopter,Consequently laid groundwork for resolving technology problem on parachute jump from the helicopter.
