The mathematical model allowing one to describe interior ballistics processes in the barrel and in the combustion chamber of a compact pulse jet engine (CPJE) located within the model while it moves in the barrel is presented. On the basis of the scheme with a traveling charge (TC), a modification creating various conditions of charge burning in the combustion chamber of the engine of the mathematical model is described. The calculation of the interior ballistics processes in the barrel and chamber of CPJE in adjoint problem formulation corresponds to the known laws of inside-chamber processes in jet engines. The critical mode expiration of the nozzle and transient mode of the CPJE behavior are discussed. The calculated curves of the maximum pressure distribution along the barrel and graphs of pressure products combustion in the axial coordinate at different times are presented. The calculated and experimental values of the velocity coincide with an accuracy of 3–5%. The gas-dynamic features of the moving model with a CPJE inside the barrel were researched via this mathematical model. Experimental results of the body motion during the exterior part of the trajectory with a running CPJE are presented.
Keywords: mathematical modeling (simulation), interior ballistics, pulse jet engine.
