Liquid Rocket Engine Concept for SMILE Launcher
21st AIAA International Space Planes and Hypersonics Technologies Conference, 2017The development of the liquid propellant engine within the frame of the SMILE Project is described in the current paper. The analysis of a generic liquid propelled rocket launcher was performed and resulted in a description of the engines of each stage. The focus of this work is on the performance analysis of the first stage engine.

Transverse Waves in Simulated Liquid Rocket Engines [PDF]
AIAA Journal, 2011 This work seeks to provide a closed-form analytical solution for the transverse vorticoacoustic wave in a circular cylinder with headwall injection. This particular configuration mimics the conditions leading to the onset of traveling radial and tangential waves in an idealized liquid rocket engine.

Regenerative cooling for liquid rocket engines [PDF]
Journal of Thermal Science, 1995 Heat transfer in the thrust chamber is of great importance in the design of liquid propellant rocket engines. Regenerative cooling is an advanced method which can ensure not only the proper running but also higher performance of a rocket engine. The theoretical model is complicated, it relates to fluid dynamics, heat transfer, combustion, etc...

Laser Ignition in Liquid Rocket Engines [PDF]
30th Joint Propulsion Conference and Exhibit, 1994 The objective of this study was to evaluate the feasibility of using laser ignition in liquid rocket engines. Three mechanisms of laser ignition were evaluated. One method, Laser Induced Spark (LIS) ignition, was tested and the results are presented. For the LIS ignition tests, a Nd:YAG laser, at a wavelength of 1064 nm and repetition rates up to 20 Hz,

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 ...

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 ...

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.

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.
