Description
Summary:Based on the results of studies of jet power propulsion systems with a pulsating working process, the thrust in which is significantly increased due to the gas mass attachment, and the analysis of the operation of a laser jet engine (LJE), we consider the possibility of such an effect in an LJE. The thrust characteristics of pulsating jet engines with the gas mass attachment are studied numerically and theoretically. Investigation of the effect of the attached mass of a gas or ablation products of the reflector material in the LJE is promising for optimising the gas-dynamic parameters that ensure the implementation of the maximum thrust efficiency of such an engine.
