DIRECT THRUST AND EFFICIENCY MEASUREMENTS OF A CONTINUOUS PLASMA ACCELERATOR

摘要: Experiments were performed with a continuous Lorentz or J x B accelerator, using an arc jet plasma source and argon nitrogen expellants. At flow rates of 0.003 lb/sec, directly measured thrusts up to 3,6 lbf, exclusive the jet, obtained, acceleration efficiencies as high 54%. The specific impulse increment due accelerator was 1200 sec corresponding addition 300% used in these experiments. (auth)
