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.

Liquid-Propellant Rocket Engines

2012
The liquid-propellant rocket engine has the characteristics that allow it to deliver thrust at a high-performance level, with an efficiency and operational flexibility that enables a number of mission applications to go forward. Monopropellant and bipropellant versions of this category of engine are discussed in some detail in this chapter.

MODELING TECHNIQUES FOR LIQUID PROPELLANT ROCKET COMBUSTION PROCESSES

Symposium (International) on Combustion, 1963
A qualitative physical processes description of stable and unstable combustion in rockets is presented to establish the basis for choosing model hardware design criteria. It is concluded that it is not possible to scale rocket combustion processes in the usual sense of the term.

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.

Rocket Classifications, Liquid Propellant Rockets, Engine Selection, and Heat Transfer

1968
In a broad sense, propulsion is the act of changing the motion of a body. Propulsion mechanisms provide forces which move bodies that are initially at rest, change a constant velocity motion, or overcome retarding forces when a body is propelled through a medium.

High Energy Liquid Propellants for Rockets

1960
High energy rocket propellants (such as fluorine, hydrogen, hydrazine, etc.) are of great interest because they result in large increases in vehicle performance over that possible with conventional propellants. This means that for any mission to be accomplished the size and weight of the vehicle required would be smaller for the high energy propellants

Fundamental of Acoustic Instabilities in Liquid-Propellant Rockets

1992
Abstract : The objective of this research was to improve understanding of the mechanisms by which flow, mixing and combustion processes are coupled to acoustic fields in liquid propellant rocket motors. Particular attention was focused on analyses of amplification mechanisms coupled with finite rate chemical reactions by use of numerical and analytical
