Abstract
A vertical lift aircraft includes a central cabin and a set of concentric, circular, counter-rotating power blade assemblies. Gas turbine engines located in the central cabin provide power for rotating the power blade assemblies to cause lift and motion of the aircraft. The turbine engine exhaust gases are directed through a rotatable exhaust nozzle for aiding in the thrust and momentum of the aircraft. The gas turbine engines drive electric power generators which provide the necessary power for operation of the aircraft.
