Abstract: The invention relates a method and apparatus for reducing the drag on aircraft, particularly aircraft with an upswept afterbody. The method includes the steps of positioning a plurality of drag reducing elements on the fuselage of the aircraft, wherein the drag reducing elements are positioned on the fuselage from a position at the breakline of the fuselage and extending toward the tail of the aircraft. In preferred embodiments, each of the plurality of drag reducing elements is positioned such that a first end of the drag reducing element is at an angle of between approximately 15 and 35° nose up relative to the flow of air about the fuselage at the location where the drag reducing element is positioned.

Abstract: A wall structure is provided and includes a series of spaced apart studs with each stud having a web and a pair of flanges. A series of support backings are connected between the spaced apart studs. Each support backing includes an elongated main section and a first tab formed on one end of the main section and extending at an angle with respect to the main section. A corner is formed between the main section and the first tab and one or more openings are formed in the corner. One or more tabs project from the other end of the main section. To secure the support backings within the wall structure, fasteners are utilized to secure the first tab of the support backings to the webs of the studs. Furthermore, the second tabs of the respective support backings project through the openings formed in the corner.
