This article presents the results of research on manufacturing and testing a target missile cruise engine using RST solid propellant. In particular, we have researched and calculated the design of a test engine, and built a flow chart to calculate the system of internal discharge equations of the engine. Research on the design and manufacture of propellant doses for cruise engines, including presenting the technology for manufacturing fireproof coatings for solid propellant ingots and perfecting the complete propellant dose. Test combustion of the cruise engine on a static stand has been conducted. The results of the tested engines are stable, the main parameters obtained are as follows: Pressure Pmax = 61,9 bar; Burning time 31,75 seconds; Average engine thrust: 670,7 N, Total thrust impulse: 21247,9 N.s, Engine housing temperature during the engine working period is equivalent to the ambient temperature after the engine stops thermal operation Engine cover temperature increased to 86 oC. This is the largest solid propellant cruise engine researched and manufactured by domestic units, on that basis creating a new type of MTB01 flying target with a maximum speed of 248 m/s, flight time of not less than 60 seconds.
