Electrification of nozzle in a liquid rocket engine
Combustion, Explosion, and Shock Waves, 1995A method of electrical-physical diagnostics is developed and experimental studies are conducted of the process of nozzle electrification in a liquid rocket engine operating on a hydrocarbon fuel. The highest electric potential is shown to be realized at about a stoichiometric ratio of the components, i.e., when the flow velocity, temperature, and ...

Performances Study of Liquid Rocket Engine
Applied Mechanics and Materials, 2014The article presents the performance of the liquid rocket engine. It will study the combustion reaction of the liquid hydrogen and oxygen without thermal dissociation. The main elements studied are the influence of the exces of the oxidant on firing temperature, on exhaust velocity, on the evacutation temperature from the engine and on the ishotermal ...

On porous liquid propellant rocket engine injectors
Aerospace Science and Technology, 2008A 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.

Design of liquid-propellant rocket engines
Journal of Machinery Manufacture and Reliability, 2012A 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 ...

Design Procedure of a Movable Pintle Injector for Liquid Rocket Engines
, 2016Variable-area injectors are suitable choices for developing throttleable rocket engines because it is difficult to efficiently control thrust when fixed-area injectors are used. A pintle injector is a variable-area injector that can control the mass flow

Liquid oxygen monopropellants for rocket engines
30th Joint Propulsion Conference and Exhibit, 1994A series of tests were performed to determine the feasibility of premixing fuels with liquid oxygen to form a rocket engine monopropellant. The fuels sclccted for cvaluation were kerosene, motor oil, propane, natural gas, ground automobile tires, uncurcd R45HT binder and coal.
