It is an object of the present invention to reduce the wave resistance by disposing a fluid element such as an engine nacelle in a predetermined position on the upper surface of the main wing, and positively superposing the air flow generated by the fluid element onto the air flow on the upper surface of the main wing, thereby reducing the peak of the negative pressure on the upper surface of the main wing to retard the generation of a shock wave. If the engine nacelle is disposed on the upper surface of the main wing, and the longitudinal position of th...
[ What is claimed is:] [1.]1. A method for reducing a wave resistance in an airplane, which comprises disposing a substantially cylindrical engine nacelle covering a gas turbine engine within a main flow above a rear portion of an air flow on an upper surface of a main wing of an airplane, for generating a negative pressure on the upper surface of the main wing of the airplane cruising at a transonic speed, superposing a decelerated region of the main flow generated in front of the engine nacelle onto the air flow on the upper surface of the main wing to...
