Performance characteristics of a high-pressure jet generator

Over the last several years, Rocketdyne has conducted a number of experiments on advanced jet generators. A number of these experiments were described last year at this conference. In this paper, additional detail describing the experiments are presented and new analyses are included. The experiments show that the jet generator is operating in the kinetic limited regime. A nozzle power flux of almost 400 watt/cm2 was demonstrated at a 20 kW power level.
