Research overview:
The thermal battery is developed as a power source for the electric actuator for driving movable nozzle to reduce cost of M-V rocket. So far, the electric power to the third step electric actuator was supplied by the silver oxide cell but by changing it to the thermal battery significant reduction in cost is attained. On the other hand, as a power source for the second step actuator, which requires a large amount of current, the power source except for the thermal battery cannot be admitted. In 2001, the ground combustion test was performed and specification of the flight model was completed for the second step battery. For the third step battery, FM development has been completed.
