The nitrogen or helium propellant in the thrusters was heated to a maximum of around 2,300 K (800 s of Isp for hydrogen propellant) by concentrated solar energy, using the 0.6 and 1.6 solar concentrators of NAL, and a very precise concentrator of 10 m in diameter, made from 181 locally paraboloidal segmented mirrors by Tohoku University. Unfortunately, these axisymmetric thrusters usually only work at perigee or apogee, meaning inconvenience for the orbit transfer from LEO to GEO. The next step is therefore an opposed-cavity STP thruster heated with a pair of cavities aligned in a back-to-back position. The opposed-concentrator, which consists of a pair of face-to-face concentrators, heated the opposed-cavity thrusters successfully, allowing NAL to establish a basis for STP thruster technology.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
