A model of the Transonic Truss-Braced Wing aircraft in a wind tunnel at NASA's Ames Research Center. By early 2019, following extensive wind tunnel testing at NASA Ames Research Center, an optimized truss and more sweep for the 170 ft (52 m) span wing allowed flying higher and faster, up from Mach 0.70–0.75 to Mach 0.80 like current jetliners.

A fixed-wing aircraft may have more than one wing plane, stacked one above another: Biplane: two wing planes of similar size, stacked one above the other. The biplane is inherently lighter and stronger than a monoplane and was the most common configuration until the 1930s. The very first Wright Flyer I was a biplane.
For aircraft of moderate engine power and speed, lift struts represent a compromise between the high drag of a fully cross-braced structure and the high weight of a fully cantilevered wing. They are common on high-wing types such as the Cessna 152 and almost universal on parasol-winged types such as the Consolidated PBY Catalina .
The Henderson Longster is a conventional landing gear equipped, wire braced parasol wing aircraft. Aeronautical designer Ivan Diggs designed a new 30 ft wing for the Longster. [1] The wire bracing is supported by a central cabane post located over a 1 U.S. gallon (3.8 L; 0.83 imp gal) above-wing fuel tank. The fuselage is steel tubing.

Eight aircraft were ordered by the IGN, based at Creil airfield to the north of Paris. The aircraft's wing design made it ideal for long-duration, low-speed flight, ideal for aerial photography and survey work. These machines were designated HD.34 and were fitted with an extensively glazed nose and an offset retractable nosewheel. They flew ...
Lachassagne estimated that the camber-changing features added about 15% to the weight of the wing. Broad chord ailerons occupied about 40% of the span. Each wing was wire braced with two pairs of long Vs from the spars at about mid-span, one to the upper fuselage and the other to the landing gear. [1]
