"Basic Study on Carbon Nanotube Actuator aimed at Flatness Controllingof Large Antenna Panel of SPS"

SSPS is a large-scale power generation satellite that is constructed from power generation and transmission panels. Solar arrays will be mounted on the power generation side and generate electricity by the sunlight. Microwave antennas will be mounted on the transmission side and transmit energy to the earth by the microwaves. Power transmission side will always face to the earth. Cyclic thermal deformation will occur in the power generation and transmission panel because the irradiation conditions of the panel by the sunlight are cyclically changed. Thermal deformation in the panel will decrease the power transmission efficiency. So we have been developing the flatness controlling of the large-scale antenna panel of SPS using carbon nanotube actuators. We describe the experimental results of generating power by CNA and prediction of figure of CNA.
