초록

A supersonic aircraft having highly swept subsonic leading edge portions of the wings provided with boundary layer control suction slots. When the airplane is operating at high angles of attack under circumstances where noise is objectionable, air is drawn in through the suction strips to alleviate separated air flow and substantially eliminate (or at least alleviate) vortices that would otherwise develop over the upper wing surface. This improves the L/D ratio and permits the engines to be at a lower power setting, thus alleviating noise. There are show...

청구항

A supersonic aircraft comprising: a. an airfoil having an upper surface and a highly swept subsonic leading edge portion which is arranged to develop at high angles of attack separated flow that develops into a vortex that travels over the upper surface of the airfoil; b. said leading edge portion having an outer surface and having at said outer surface a boundary layer control suction strip means extending along said leading edge portion; c. suction means to draw in outside air through said suction strip means; and d. said suction means being arranged a...
