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.

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 ...

On porous liquid propellant rocket engine injectors

Aerospace Science and Technology, 2008
A novel injection concept for cryogenic liquid propellant rocket engines has been tested and verified successfully using an optically accessible combustion chamber. The injector consists of a porous faceplate made from sinter metal and five LOX posts arranged in a classical parallel showerhead configuration.

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.
