Patent ID: 8265807

Claim:
An automatic takeoff apparatus for an aircraft comprising: an altitude sensor for measuring an altitude of the aircraft from a ground; an airspeed sensor for measuring an airspeed of the aircraft; an attitude angle sensor for detecting an attitude angle of the aircraft; a direction sensor for detecting a direction of the aircraft; a takeoff command inputting section for inputting a takeoff command; and a control device for controlling a propulsion device and a control surface of the aircraft based on the altitude of the aircraft from the ground, the airspeed of the aircraft, the attitude angle of the aircraft, the direction of the aircraft and the takeoff command, wherein the control device comprises: a takeoff run control section for realizing a takeoff run by controlling the propulsion device to provide a maximum output and by controlling the control surface to maintain the attitude angle and a traveling direction of the aircraft constant, in response to the takeoff command; a rotation control section for controlling the control surface to perform a rotation when the airspeed of the aircraft exceeds a predetermined takeoff judgment speed; and an ascending flight control section for controlling the propulsion device and the control surface to make the aircraft perform an ascending flight up to a predetermined target altitude with a predetermined ascending speed maintained, when the altitude of the aircraft from the ground exceeds a predetermined takeoff judgment altitude and an altitude change rate of the aircraft, at a time when the aircraft is off the ground, exceeds a predetermined takeoff judgment altitude change rate.
