Abstract
PURPOSE: To reduce the wave making resistance at a transonic and supersonic flight time by cutting off the rear edge of a wing end. CONSTITUTION: An wing end of a sweepforward wing 1 is formed in a shape removed a triangular rear edge cut off part 5 from the area surrounded by a linear front edge 2 shown by a solid line and a rear edge 3 on the straight line shown by solid line and a two dots chain line. As the pressure of the rear edge is almost same under the same flow condition generally, regardless of a wing section, in the position of the wing end rear edge 6, for example, the pressure distribution near the position shown by the two dots chain line of the rear edge 3 assumes the aspect advanced in nearly parallel with a wing chord length S as it is. From the principle of the continuity of material phenoma, the pressure distribution of the front part is deviated forward correspondingly and as the result, an isobar 4 gradually approaches to the front edge 2 of the wing end like a drawing. For example, as the isobar advance angle θ2 on the drawing is not changed largely, even if it reaches the wing end but a sufficient advance angle is kept, a harmful wave making resistance is not generated.
