A variable-sweep wing, colloquially known as a "swing wing", is an airplane wing, or set of wings, that may be modified during flight, swept back and then returned to its previous straight position. Because it allows the aircraft's shape to be changed, it is a feature of a variable-geometry aircraft.
Willard Ray Custer (June 6, 1899, Warfordsburg, Pennsylvania – December 25, 1985, Hagerstown, Maryland) was an American engineer and aircraft visionary, inventor of the channel wing concept. [ 1 ] Custer left school at age 13, working as a blacksmith and, later, an engineer and mechanic.
Custer developed a wing design incorporating a semi-circular channel or "half barrel" shape in which an engine was to be fitted, in order to draw air over the wing and, in 1929, he received a United States patent. [1] The arrangement is intended to draw enough air over the wing, even when moving slowly, to create sufficient lift to fly.
The first was completed 15 February 1951, and the two aircraft made their first flights on 20 June and 10 December 1951. Almost 200 flights were made at speeds up to Mach 0.9 and altitudes of 40,000 ft (12,000 m). One aircraft was lost on 14 October 1953, when it failed to recover from a spin at 60° sweepback.
Channel Wing aircraft CCW-5. The channel wing is an aircraft wing principle developed by Willard Ray Custer in the 1920s. The most important part of the wing consists of a half-tube with an engine placed in the middle, driving a propeller placed at the rear end of the channel formed by the half-tube.

The Custer CCW-5 was a twin-engined, 5-seat aircraft of pusher configuration, which used a channel wing claimed to enable low speed flight and short take-offs. Two CCW-5s flew, eleven years apart, but the type never entered production. The aircraft was the third and last of a series of Custer Channel Wing designs.
A second U.S. carrier strike group departs from Norfolk, Virginia, on Friday. Scores of aircraft are heading to U.S. military bases around the Middle East. The US is moving quickly to boost Israel ...
The aircraft is predominantly made from wood and covered in doped Ceconite. The wing leading edge is made from poplar plywood and supported by nose ribs made from marine-grade plywood. The wing spar cap strips and tail ribs are fashioned from spruce. The tailboom is an aluminium tube. Its wing is cantilevered and tapered from wing root to wing ...
