초록

An airplane has a plurality of airfoils with leading edges. A partition and a nose cap are located at a forward surface of the airfoil, creating upper and lower cavities. The nose cap may be positioned in an extended position or a retracted position. The nose cap is retracted when the airplane reaches supersonic speed. At supersonic speed, a shock wave forms on the leading edge of the airfoil. A compression zone forms between the shock wave and the leading edge, diverting the heat and pressure of the shock wave away from the airfoil. Downstream from the ...
