PROBLEM TO BE SOLVED: To improve the opration performance of an engine by constituting the alley of a solar cell panel for supplying an electric power to a space ship thrust engine by plural solar cell panels connected in series and outputting the total voltage equal to the sum of voltage supplied from respective solar cell panels. SOLUTION: A spaceship 10 has an electric thrust engine 16 driven by the electric circuit including an electric start circuit 18 and is provided with the developed solar cell panel 12 provided on a hull as a power source. Here, the solar cell panel 12 is electrically connected as series-parallel alley 20 and connected to the input terminal couple of the electric start circuit 18. In other words, respective solar cell panels 12 are connected in series as rows 28A-28C and joned for terminals 22, 24 in a row. A diode 30 is included to connect the panels 12 of respective rows 28A-28C with a common connection point 32. The electric start circuit 18 is composed of a condensor 36, inductor 38, transistor 40 and start pulse generator 44. |
