Liquid-Propellant Rocket Engine Injector Dynamics

Journal of Propulsion and Power, 1998
The dynamic characteristics of liquid-rocket injectors in the presence of intense combustion-chamber and propellant feed-line oscillations are discussed. Liquid-propellant injectors always function in nonsteady e ow environments and are therefore considered as a dynamic component of an engine.

Simulation of liquid propellant rocket engine combustion instabilities

17th Aerospace Sciences Meeting, 1979
A simulation technique for studying the high frequency combustion instabilities of liquid propellant rocket engines has been developed and used to investigate various aspects of instability phenomena. Of importance was investigation of the significance of the method of coupling the combustion and the gas dynamics of the system.

Propellant Injector Influence on Liquid-Propellant Rocket Engine Instability

Journal of Propulsion and Power, 2015
The avoidance of acoustic instabilities, which may cause catastrophic failure, is demanded for liquid-propellant rocket engines. This occurs when the energy released by combustion amplifies acoustic disturbances; it is therefore essential to avoid such positive feedback.

Design of liquid-propellant rocket engines

Journal of Machinery Manufacture and Reliability, 2012
A design method for liquid-propellant rocket engines is proposed, on the basis of models adjusted in response to test results. This method increases the reliability of the results and reduces ground testing of the motors. The effectiveness of the method is confirmed by ground testing and flight experience with the motors developed by Salyut Design ...

Thermostructural composite materials for liquid propellant rocket engines

23rd Joint Propulsion Conference, 1987
Since more than twenty years the possible utilisation of high temperature and oxydation resistance of ceramics was considered by rocket engines designers but brittleness and poor thermal choc resistance was a major disadvantage for those materials emergence.

Fundamental Concepts on Liquid-Propellant Rocket Engines

2020
The engine of a rocket vehicle is a machine which produces thrust by accelerating a gas flowing through the machine. The reaction to this acceleration is the force which drives the vehicle. The amount of thrust generated depends on the mass flow rate of the gas moving through the engine and on the exit velocity of the gas from the nozzle. The gas flow,
