Abstract

The invention provides, in vertical and oblique lift and descent, horizontal flight and hovering, for maintenance of attitude of an airframe, using a single wing, large blades and a single large rudder, under divergent airflow. To change attitude in hovering from horizontal to vertical, in case three wings are provided on the airframe, the output of an engine mounted on a wing at the front part of the airframe is increased, the lifting power is increased and the front part of the airframe rises from the horizontal. Then output of an engine of the rear part of the airframe is reduced, and the lifting power of the rear part of the airframe is diminished. When an angle of the airframe is increased, a second wing located in the central part of the airframe is moved to a 90 degrees vertical direction and an output occurs so that the altitude of the airframe does not drop.

Claims

1. A vertical takeoff landing aircraft comprises:

movable wings that constitute a plurality of wings, wherein the plan part of each wing is movable from horizontal to vertical direction installed to the top of an airframe;

a jet-wind generation device installed to the plurality of wings operative to generate a jet-wind,

a rudder is operatively installed to a proximity right behind the jet-wind generation device and operatively controls a moving direction of the airframe and a flap is operatively installed to a proximity right behind the jet-wind generation device and is operative so as to control an up-and-down direction of the airframe,

a plurality of sensors operative to detect the direction/rising/down/rotation/position/airframe attitude/speed/altitude/distance to an obstacle is installed to each said movable wing, and

a control module installed to said airframe operative to conduct the attitude control based on the detected data by each sensor.

2. The vertical takeoff landing aircraft according to claim 1, wherein:

said jet-wind generation device is installed in the middle between said airframe and said plural wing tips.
