Abstract
This paper shows design, fabrication and experimental results of a large (50mm) cavity diameter windowless type of solar thermal propulsion (STP) thruster made of single crystal molybdenum (SCM) with tungsten chemical vapor deposition (W-CVD) coating. The nitrogen or helium propellant in the thruster plenum chamber was heated up to about 2,OOOK (750s of Isp for hydrogen) by the 10m diameter big concentrator of Tohoku Univ. of very precise paraboloidal shape. But it was difficult to measure the very small thrust under the very high temperature and vacuum condition.
