Note (General): Solar energy is already used in the form of electric power generated by solar cells in satellites. And a solar thermal propusion system, a kind of gas jet engine, has been studied. Large expansion area engines have been studied to achieve high specific impulse, Isp. If external energy is added to an engine, Isp can be better than the theoretical Isp based on tank level enthalpy. In this report, solar energy was used as the additional energy supplied to a rocket engine. The LH2/LO2 expander cycle engine with a solar heat exchanger was studied. This engine has two merits. One is the increase of Isp, which allows a greater payload to be carried by a rocket with the solar heat exchanger than by a normal rocket. The other merit is a cycle pressure level decrease. The Isp increase is realized for every engine and for every propellant, if additional energy is available.
