Design and Evaluation of a Turbojet Exhaust Simulator, Utilizing a Solid-Propellant Rocket Motor, for use in Free-Flight Aerodynamic Research Models A method has been developed for modifying a rocket motor so that its exhaust characteristics simulate those of a turbojet engine. The analysis necessar...
18,774, and 47,175 were created to verify the grid independence. Numerical simulations of nozzle ablation in a solid rocket engine using an Al-containing propellant were conducted. The ablation rate results at the three different axial points are listed in Table1. Notably, the results from...
In military applications and cabinet in space research, the rocket motor sends the warhead to the intended destination. In the design of the rocket engine, the specific impulse (Isp), the burning rate (r), the propellant density (ρb), the combustion chamber pressure (Pc), the intended ...
Solid rocket motor cladding thickness has been the focus of research at home and abroad, coating layer is too thick or too thin will affect its functioning, therefore before the propellant casting, coating thickness should be measured to avoid engine failures. Solid rocket motor cladding thickness ...
The aluminum particles in the propellant cause a lot of effects on the solid rocket motor working process, for example, increasing propellant energy, causing loss induced by two-phase flow, and affecting unstable combustion. Existing studies mainly focus on the effect of aluminum content, thus ...
Currently, EPDM represents one of the best matrices among elastomers used on solid rocket motor (SRM) liners [17]. Solid rocket motor is a rocket engine that uses solid propellant as fuel. Combustion produces gases that are expanded through a nozzle to generate thrust. EPDM/aramidic ablatives...
Hence, the air-breathing engine has a comparatively higher specific impulse (Isp) [1]. In conventional rocket propulsion systems, the Isp (actual) for a typical propellant composition has not yet reached beyond ∼450 s, whereas for air-breathing engines, 500 s had been easily achieved [2]...

Typically, once the propellant grain shape of the engine is confirmed, the thickness of the burned propellant can describe the variation of Vc and Ab. By modifying Ab, it is possible to simulate the dynamic process inside the combustion chamber using numerical solution methods, thereby creating a...
