Calculation of the parameters and characteristics of a rotating lunar jet penetrator

The purpose of the work is to determine the parameters of the internal ballistics of a solid fuel jet engine mounted on a jet penetrator entering the ground at a high rotation speed around its own axis. Research methods: to determine the pressure in the chamber of a rotating engine, the known equations for the balance of gas inflow and consumption are usually used, as in the case of a non-rotating solid fuel jet engine. The difference between the internal ballistics of a rotating solid fuel jet engine is that the effect of rotation on the operating process is taken into account by the coefficient of gas flow from the chamber of the rotating engine; a change in the rate of erosive combustion of solid fuel during rotation of a solid fuel jet engine; heat loss coefficient.
