JAPANESE JOURNAL OF MULTIPHASE FLOW, 1997 PURPOSE:To boost propellant to a high pressure without using a subcombustor by reheating a part of the propellant heated by the heat of a combustor by using a heat exchange means in a nozzle part. CONSTITUTION:The liquid hydrogen as fuel and liquid oxygen as oxidizer are pressurized to each high pressure by boosters 3 and 4.

Resonance in Liquid Rocket Engine Systems [PDF]
Journal of Basic Engineering, 1965 A transient flow analysis of a longitudinal vibration in a liquid rocket engine propellent feed system and its supporting structural framework is described, together with supporting experimental tests. Nonlinear friction losses are used in the partial differential equations of continuity and momentum describing the unsteady flow.
