Abstract:
PURPOSE: A radio control miniature aircraft is provided to facilitate carriage in consideration of work conditions and to enable the miniature aircraft to take-off and land even in a limited space. CONSTITUTION: A radio control miniature aircraft comprises a body part(10) and wing parts(20) made of a lightweight material. The radio control miniature aircraft is capable of flying by utilizing power supplied from an engine. The radio control miniature aircraft has a line dropping device where an air drop(100) to which a pilot line is connected is mounted and detached. Flying and line dropping control action wherein the air drop is detached from the line dropping device are possible by worker's wireless remote control.
Abstract:
The remotely piloted aircraft has control surfaces asymmetrical in the pitch and yaw planes, a sensor, and a guidance system operative in the terminal portions of the flight of the aircraft in a yaw-to- turn mode with a zero roll rate. The system has a directional sensor for providing azimuth and elevation error signals. A device provides guidance signals indicative of the rate of change of the azimuth and elevation signals. A guidance programmer responds to the guidance signals for providing pitch control and yaw control signals. An altitude sensor provides an altitude control signal. Roll, pitch and yaw rate gyros provide a rate control signal and a three axis autopilot.
