Abstract

During the last few years there has been an increasing interest in a high-lift wing configuration known as the flex-wing, or parawing. The parawing consists basically of a flexible membrane such as cloth, attached to two leading edges (or booms) and a keel as shown in Figure 1. At angles of attack (��) greater than the billowing angle (��). the air impinges on the under side of the membrane and forces it into a double-arch shape at each cross-section. When straight leading edges are used, each arch approximates the shape of a conical section. A cylindrical section is obtained by giving the leading edge a circular arch shape as seen from head on
