Abstract:

Break-up activity of water by injection of hot propellant gas into channels of a thrust expansion engine is suppressed to prevent rapid cooling of the gas, utilizing one or more methods including injection of a secondary inflow of the propellant gas andor the water under lower pressures into the channels, injection of a viscosity enhancer andor surfactant into the inflow stream of the water and restricting outflow of the water from the channels by means of convergent nozzles.
