초록

A thin, high performance swept wing of the tapered type with an improved leading edge characterized by a first portion that extends from near the wing root at a fixed radius to a transition point where twice the fixed radius does not exceed about 100.6 percent of wing thickness at about 5 percent of the local chord at the transition point, and a second leading edge portion extending from the transition point to the wing tip that has a radius expressed in percent of local chord which does not exceed that percent of local chord at the transition point. Win...
