赤外線によるロケットの姿勢検出

Abstract

The attitude of a rocket is determined by two kinds of angle which are formed between the axis of a rocket and two standard lines. The one is a pitch angle, and the other is a yaw angle.In this paper, the method of the design of a horizon sensor device to determine a pitch angle, the observed results using it and the discussion on them are reported.The output of this device is remarkably affected by the several factors such as the time constant of a sensor, the altitude and the attitude of a rocket and the setting angle of a sensor for a rocket. So that, making these factors as parameters, the method of the design for the optical system and the amplifier of this device were studied.Two horizon sensor devices designed based on these results were boarded on the rocket L-3H7 and the rocket K-10-10 respectively. The observed results by these two devices gave not only the pitch angles of two rockets, but also the temperature distribution of the earth from which the yaw angles were gained.
