One potentially attractive propulsion concept offering significant payload gains for orbit transfer from LEO to higher orbits, station keeping and attitude control of spacecraft is thermal propulsion using light gas (typically hydrogen) as propellant and various kinds of heat energy. Solar Thermal Propulsion (STP) is a typical thermal propulsion with high Isp (500 - 1,000 s) in an appropriate thrust...
The heart element of solar thermal propulsion (STP) system is a thruster made of refractory metals such as tungsten, tantalum and molybdenum or advance high temperature ceramics because of the high operating temperature (1000-2500 K) involved. In this paper, design, fabrication and preliminary experimental results in the JSUS Research Plan are presented, using 20 mm diameter of thrusters made of...
