ABSTRACT:
A line-controlled, centrifugal fan, jet-propelled model airplane is disclosed in which the impeller of a fan contained within the fuselage of the aircraft is driven from a remote drive unit by an elongated flexible cable contained within a flexible sheath. The impeller rotates about an axis perpendicular to the longitudinal axis of the airplane and is driven in a direction of rotation tending to rotate the airplane about its lateral axis in a nose-up direction, due to the frictional contact of the compressed air between the rotating impeller and the housing of the centrifugal fan mounted within the fuselage. A flywheel powered by the electric motor in the remote drive unit controls the rate of acceleration and deceleration of the aircraft as an electric motor in the drive unit is switched on and off.
