A highly tapered wing tip extension added to the tip of an existing swept, trapezoidal airplane wing for reducing high speed drag significantly. A smaller, highly swept, extension does not require a leading edge device to protect against low speed stall. A larger, less swept, extension requires a tapered slat for which two mechanisms are presented. The principles of the present invention are also applicable to the design of new aircraft.
Apparatus for improving the aerodynamic performance of an aircraft capable of attaining but not exceeding high transonic speeds, said aircraft having a tapered planform, geometrically twisted, main wing, said main wing having a leading edge sweepback angle greater than about twenty-seven degrees (27°) and less than about forty degrees (40°), said apparatus comprising a tapered wing tip member adapted to be secured to each outboard end of said main wing, said main wing and said wing tip member having a spanwise lift distribution approximating that of an e...
