CONTROL PECULIARITIES OF ROCKET ENGINE WHICH RUNS ON ECOLOGICALLY-FRIENDLY STORABLE PROPELLANT

On the hydrodynamics of rocket propellant engine inducers and turbopumps

The lecture presents an overview of some recent results of the work carried out at Alta on the hydrodynamic design and rotordynamic fluid forces of cavitating turbopumps for liquid propellant feed systems of modern rocket engines. The reduced order models recently developed for preliminary geometric definition and noncavitating performance prediction of tapered-hub axial inducers and centrifuga...

Substructure Method for Thermal-Stress Analysis of Liquid-Propellant Rocket Engine Combustion Chamber

This article is devoted to an important problem of calculation of deflected mode of the combustion chamber and the nozzle end of a new liquid-propellant rocket cruise engine. A special attention is given to the methodology of calculation. Three operating modes are considered. The analysis has been conducted in ANSYS software. The methods of conducted research are mathematical modeling, substruc...

Dispersion of Toxic Exhausts from Liquid Rocket Propellant Combustion 25 Dispersion of Toxic Exhausts from Liquid Rocket Propellant Combustion

Environmental impact assessment of liquid rocket motor exhaust obtained due to mainly liquid propellant combustion have been highlighted. Exhaust product analysis has been carried out theoretically by computer software NASA CEC -71 to identify toxic emissions of rocket combustion. In the present study a high volume Air Samplers (APM-430) was deployed at predetermined locations near launch pad f...

Regression rate study in a small Hybrid Rocket Engine using N 2 O / paraffin propellant

1 Abstract: In the frame of the FAST20XX project under the supervision of ESA, two hybrid rocket engines are developed at Université Libre de Bruxelles (ULB) in collaboration with the Royal Military Academy of Belgium to assess the performance of paraffin/N2O propellants. The goal behind the study is to measure the regression rate and optimize the size of ALPHA, which is a sub-orbital vehicle d...
