Technical Report of National Aerospace Laboratory TR-670
For a three-axis-stabilized satellite with reaction-control thrusters and extended solarcell paddles, the thruster-exhaust-plume impingement on the paddle causes a plume-impingement disturbance torque. A method of theoretical estimation of the plume torque is established and the PITS (plume-impingement torque simulation software) is produced. The plume torque obtained by the PITS is compared with the plume-torque data of the Japanese medium-scale broadcasting satellite for experimental purpose (BS). The roll, pitch, and yaw torque indicate resasonable agreement with the BS data, although the roll torque is in partial disagreement. Since the present theoretical model can reasonably estimate the BS plume torque, the PITS may be available for plume-torque estimation in forthcoming three-axis-stabilized satellites.
