초록

A method to reduce the wave resistance of an airplane by disposing a fluid element such as an engine nacelle at a predetermined position on an upper surface of a main wing, positively superposing the air flow generated by the fluid element onto the air flow on the upper surface of the main wing, thereby establishing a gentle profile of pressure on the upper surface of the main wing, and retarding 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 the front end of the e...

[ What is claimed is:] [1.] A method for reducing the wave resistance of an airplane having a main wing, with a negative pressure being generated by an air flow on an upper surface of the main wing when the airplane cruises at a transonic speed, the method comprising the following steps:supporting a substantially cylindrical engine nacelle covering a gas turbine engine by a pylon extending upward from the upper surface of the main wing;locating a front end of said engine nacelle to be within a main flow of air above and at a rear of the air flow on the u...
