「SSPSの形状制御を目的としたカーボンナノチューブアクチュエータの研究」

SSPSは多数の発送電一体型パネルによって構成される大規模発電衛星である.発電側に太陽電池,送電側にアンテナを搭載した発送電一体パネルが用いられ,マイクロ波で地上へエネルギーを送る.静止衛星軌道上に建設されるSPSは,送電側は常に地球方向を向き,太陽との位置関係が周期的に変化する.そのため,発送電パネルは周期的な熱変形が生じる.その変形を補正するため,カーボンナノチューブアクチュエータによる制御を提唱し,検討を行っている.本論文では,CNAの発生力と変形形状予測について論じる.

"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.
