A Mathematic Model Applied for the Hood Separation of Underwater Launching Aircraft's Carrier

摘要: 可水下发射飞行器是一种由水下航行体携带并在水下发射,然后在水中运动并出水飞行的新型无人飞行器。对可水下发射飞行器载体的头罩分离问题,分析头罩分离的可靠性和安全性需求和影响因素,提出一种使用爆破切割、周向和径向布置相结合的分离设计思路,并在头罩分离体受力分析的基础上对其分离计算建立了可以描述头罩分离特性,预测分离体运动轨迹的数学模型。Abstract: Underwater launching aircraft is a new unmanned aircraft which is carried,launched by an underwater vehicle,then moves in and exit the water,and flies in air eventually.For the hood separation of underwater launching aircraft,we proposed a separation design approach using circumferential and radial collocated cutting blasting considering the requirements of reliability and security.The mathematical model of the hood separation is established to calculate the hood separation characteristics and to predict the trajectory of separated bodies.The present study provides the necessary theoretical basis to the design of underwater launching aircraft.
