Influence of jet thrust on penetrator penetration when studying the structure of space object blanket
Engineering Education # 02, February 2014
DOI: 10.7463/0214.0699035
The paper presents calculations to determine a penetration depth into low-strength soil targets provided by penetrators equipped with the pulse jet engine when studying a structure of space object blanket. In movement the penetrator is considered as a rigid body of variable mass, which is subjected to the drag force and the reactive one applied at the moment the jet engine fires. Dynamics of moving penetrator with its conic nose part is described with binomial empirical law of target drag force and with assumption that the jet thrust force is constant during its application time. It is established that penetration depth into low-strength soil target can be several times increased owing to use of the jet engine. A rational time for the jet engine firing and operation is defined.
