Abstract

A vertical take-off and landing aircraft including a propulsion mechanism that generates lift and thrust, a main frame that supports seating and a landing undercarriage, a subframe which supports the propulsion mechanism and which is arranged so as to be swingable back and forth relative to the main frame, motive power supply means supported by the main frame and supplying motive power to the propulsion mechanism, and a control stick connected to the subframe in which the propulsion mechanism includes a pair of ducted fans arranged on a left side and a right side, respectively, of the main frame, swing shafts arranged in the ducted fans, and extending in a horizontal direction, and control vanes connected to the swing shafts, and swinging the control vane enables the subframe to move relative to the main frame. Maneuverability can be improved with addition of control mechanisms restrained.

Claims (12)

1. A vertical take-off and landing aircraft comprising:

a propulsion mechanism that generates lift and thrust;

a main frame that supports seating and a landing undercarriage;

a subframe which supports the propulsion mechanism and which is arranged so as to be swingable back and forth relative to the main frame;

motive power supply means supported by the main frame or the subframe and supplying motive power to the propulsion mechanism; and

a control stick connected to the subframe,

wherein the propulsion mechanism comprises at least a pair of ducted fans arranged on a left side and a right side, respectively, of the main frame, a swing shaft arranged in each of the ducted fans and extending in a direction perpendicular to a front-back direction of the vertical take-off and landing aircraft, and a control vane connected to the swing shaft; and

wherein the swing shaft includes a central swing shaft arranged in a central portion of the ducted fan in the front-back direction and a side swing shaft arranged at a front or at a back in a channel in the ducted fan, and

the control vane connected to the central swing shaft is used to deflect the thrust of the ducted fan, and swinging the control vane connected to the side swing shaft enables the subframe to swing back and forth relative to the main frame.

2. The vertical take-off and landing aircraft according to claim 1 , wherein the swing shaft and the control vane are arranged in an upper portion or a lower portion of the ducted fan.

3. The vertical take-off and landing aircraft according to claim 1 , wherein the propulsion mechanism is connected to the main frame via the subframe so as to be arranged above or below the seating.

4. The vertical take-off and landing aircraft according to claim 1 , wherein the control stick extends from the subframe to a front of the seating, and is swung back and force to swing the subframe back and forth relative to the main frame.
