The novel concept of body self-propulsion by static-pressure thrust has been introduced and verified in the wind-tunnel by direct integration of radial pressure distributions for self-propelled axisymmetric bodies with slot suction BLC and stern jet discharge. This concept also means that power can be supplied only to BLC, since the jet discharge is achieved at jet total-head equal to free-stream's; the skin-friction drag is offset entirely by the pressure thrust . It is the most efficient form of body self-propulsion. It also has been shown that 50 % power reduction has been achieved as compared to the test body/wake-propeller NASA configuration, with only 15 % of its mass flow. A total aircraft power reduction of 40 % to 60 % is feasible as compared to current General Aviation aircraft at 200 MPH cruise speed.
