Abstract

An automatic takeoff apparatus for an aircraft includes: an altitude sensor; an airspeed sensor; an attitude angle sensor; a direction sensor; a takeoff command inputting section; and a control device for controlling a propulsion device and an control surface of the aircraft, wherein the control device includes: 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 the traveling direction constant, in response to the takeoff command; a rotation control section for controlling the control surface to rotate when the airspeed exceeds a predetermined speed; and an ascending flight control section for controlling the propulsion device and the control surface to perform an ascending flight up to a target altitude with a predetermined speed maintained, when the altitude exceeds a predetermined altitude.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The disclosure of Japanese Patent Application No. 2004-120814 filed on Apr. 15, 2005, including the specification, drawings and abstract is incorporated herein by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to an automatic takeoff apparatus for an aircraft, an automatic landing apparatus for an aircraft, an automatic takeoff and landing apparatus for an aircraft, an automatic takeoff method for an aircraft, an automatic landing method for an aircraft and an automatic takeoff and landing method for an aircraft. [0004] 2. Description of Related Art [0005] So far, several technologies for realizing an automatic landing of an aircraft have been proposed. As shown in FIG. 9, what is proposed for example is an automatic landing apparatus (ILS: Instrument Landing System) for making an airframe approach and land on a predetermined airstrip 300 by transmitting a gui...

AI Technical Summary

Benefits of technology

[0015] According to the first, third, fourth and sixth aspects of the present invention, the control device (in the control step), in response to the takeoff command, controls the propulsion device of the aircraft to provide a maximum output and controls the control surface to maintain the attitude angle and the traveling direction of the aircraft constant, for realizing a takeoff run. Next, the control device (in the control step) controls the control surface to perform a rotation when the airspeed of the aircraft exceeds a predetermined takeoff judgment speed. Continuously, the control device (in the control step) controls 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.

[0016] In other words, whether shifting from the takeoff run control to the rotation control should be done is judged by referring to “airspeed” of the aircraft, and whether shifting from the rotation control to the ascending flight control should be done is judged by referring to “altitude from the ground” (above ground level) of the aircraft. Thereby, it is possible to realize a full automatic takeoff from a ground run to an ascending flight. Furthermore, at this time, since judgment of takeoff (whether a takeoff is completed and it is possible to shift to the ascending flight) is done by referring to “altitude from the ground” of the aircraft, it is not necessary to use a landing gear for judging the takeoff. Therefore, it is possible to realize the full automatic takeoff without using a complicated loaded device or a complicated control logic.

Problems solved by technology

Therefore, in reality, it was difficult to perform a landing under a full automatic control.

Since it is necessary to provide landing gear switches as many as the number of feet, a structure of loaded apparatuses became complicated.

Further, since the landing gear switch easily malfunctions, it was necessary to establish a complicated control logic under an assumption of a case of malfunctioning.
