摘要
文中针对大型冲压翼伞发展的两大难题:开伞动力学和收口技术,介绍了两种分析大型冲压翼伞气动力性能的方法——飞行性能模拟法和有限元模拟法,最后介绍了美国先锋公司开发的中幅收口技术。
The paper discusses two difficult problems in development of large ram air parachutes: dynamics of deploying and reefing technique. For the first problem, the paper introduces two approaches for dynamic's analysis of large ram air paracutes: flight mechanics simulations and finite element simulations. For the second one, a new reefing technique is introduced.
