A vertical takeoff and landing aircraft is disclosed that includes a
support structure having a motor mounted vertically thereto, with the
motor having a propeller for rotation in a horizontal plane. A power
supply for the motor is mounted to the support structure below the motor
and electrical coupled thereto. A plurality of fins are attached by their
first end to the power and extending radially outward therefrom. Vertical
posts have there first ends attached to the second end of the fins and
extend upward to the plane of rotation of the propeller. A ring is mounted
horizontally to the second ends of the plurality of vertical posts
surrounding the propeller. The torque produced by the drag of fins as the
aircraft rotates in the opposite direction reacting the torque of the
propeller equal to the torque of the propeller necessary to achieve hover.
The rotational inertia of aircraft is made equal to the rotational inertia
of the propeller.
