A robotic or remotely controlled flying platform (10) with reduced drag stabilizing control apparatus constructed having an air duct (12) with an air intake (14) on the top and an exhaust (16) at the bottom, containing supported therein a clockwise rotating fan (22) and a counter-clockwise rotating fan (24). Directly below the perimeter of the air duct exhaust are mounted a plurality of trough shaped air deflection assemblies (32) each including a rotatably adjustable half trough (44) for selectively scooping a portion of the drive air, and a stationary adjacent half trough (36) for receiving the scooped drive air and redirecting it outward and upward from the air duct. A centrally positioned plate (112) has a plurality of rods (106), each pivotably connected between the plate (74) and a corresponding lever associated with each of the adjustable half troughs (44) so as to couple the adjustable half trough (44) in or out of the drive air steam according to the position of the plate (74), thereby providing control over the pitch and roll of the flying platform. The plate is driven by first and second motors responding to input control signals. The control signals also direct the yaw of the flying platform by selectively providing independent speed control to each of the clockwise and counter clockwise fan motors resulting in duct rotation in a clockwise or counter clockwise direction accordingly.

1. A vertical take-off and landing aircraft comprising:air duct means including a duct wall having a duct periphery, and air intake at a top end and an air exhaust at a bottom end; first fan means mounted within said air duct means including a plurality of fan blades driven by a first motor means in a clockwise direction for pulling drive air into said duct means from said air intake end and pushing said drive air out said exhaust end; second fan means mounted coaxially with said first fan means within said air duct means including a plurality of fan blades driven by a second motor means in a counterclockwise direction for pulling air into said duct means from said air intake end and pushing it out said exhaust end; a plurality of adjustable trough shaped air deflector means positioned exterior to and along the periphery of said air duct means at said exhaust end; aircraft control means including deflector control means for adjusting said adjustable trough shaped air deflector means responsive to control signals for providing roll and pitch control of said VTOL aircraft; and fan control means responsive to control signals for adjusting the speed of said first and second fans for generating required drive air, and for adjusting the relative speed of said first fan to said second fan thereby causing yaw control of said VTOL aircraft.
