This type of thruster is one of several high Isp thruster concepts being studied by the Phillips Laboratory to transfer payloads from low earth orbit to geosynchronous orbit. Soar propulsive techniques should deliver close to 1000 sec of Isp using a very low molecular weight propellant,hydrogen. The purpose of this model is to determine the dependency of thrust, specific impulse, and energy conversion efficiency upon a variety of parameters including solar concentration, and propellant mass flow rate. 收起
