Knowledge of the dynamic performance of turbopumps is essential for the prediction of instabilities in hydraulic systems; the necessary information i s in the form of a transfer function relating the instantaneous pressures and mass flow rates at inlet and discharge. Cavitation has a significant effect on this transfer function since dynamical changes in the volume of cavitation contribute to t...

Method of obtaining tangential holes in the shell a combustion chamber liquid-propellant rocket engine is presented this article. Advantages and disadvantages technologies for making small diameter are consired. The developed technology tooling made it possible to obtain designed swirl coolant flow veil belt shell. As result, material labor costs were reduced manufacture components.
