HISTORY: The Custer Channel Wing Corporation

In 1951, Willard Custer formed the Custer Channel Wing Corporation with a registered address at 1905 West Washington Street, Hagerstown, Maryland.

Taylorcraft Inc of Conway, Pennsylvania were the first manufacturers to be licensed for the production of both military and private aircraft using the Channel Wing principles. The first type intended to be produced was an experimental military aircraft to comply with United States Air Force specifications for a liaison aircraft. It was to carry a pilot and three fully equipped combat troops or 10 litter patients. Performance envisaged was a 1,000-pound (450 kg) load, cruising at 150 knots (280 km/h; 170 mph) or better over a five-hour cruise range. Taylorcraft never put the plans into action. A design had been prepared by early 1952 for a single-engined channel wing aircraft with the engine fitted in a single channel immediately behind the crew cabin, but this aircraft was not built. Design numbers CCW-3 and CCW-4 were not used.

In 1978, Custer filed an US$80 million (equivalent to US$374 million in 2023) suit against the designers of the A-10 for using his idea of induced lift from the proximity of the engines to the wings. The suit was dismissed.

Custer's Corporation went on to develop and build the five-seat CCW-5, intended for commercial sale. The first example N6257C was designed by Custer but built by the Baumann Corporation of Santa Barbara, California. It utilized an adapted fuselage and tail assembly of a Baumann Brigadier. Power was from two pusher 225 h.p. Continental O-470 engines. The first flight was made on July 13, 1953.

The second example N5855V was manufactured at the Custer factory. It again used a Baumann Brigadier fuselage and tail assembly. This aircraft first flew on June 19, 1964. Although several firms expressed interest in production of the design, all failed to provide the necessary down payment.

The CCW-5 accommodated five persons, and its power plants are suspended in the center of the 6-foot (1.8 m)-chord wing channels on tubular frameworks attached to the wing spars. The aircraft draws air through the channels at high velocity, decreasing pressure over the wings and increasing lift. The CCW-5 was claimed to be capable of flying at a sustained speed of 35 miles per hour (56 km/h).

The CCW-5 continued to make developmental flights during the 1960s and 1970s, but no production orders were obtained.

N5855V was donated to the Mid-Atlantic Air Museum at Reading Airport, Pennsylvania and is on restricted display.
