The Custer Channel Wing Corporation was the brainchild of Willard Custer. His channel wing aircraft provided STOL capabilities by forcing airflow over the wing channels. The arrangement was quite effective at low speeds, but high speed performance suffered.
NASM's CCW-1 was the first of 4 channel-wing models eventually built. Initially it flew with conventional outboard wing sections in place (as displayed), but they were later removed and only channel sections of wings remained. Performance was satisfactory even with 1 engine out; as the motion of air on the dead side continued to produce enough lift to maintain control. Contra-rotating props later enhanced lateral stability. Cross shafting between engines was considered but was never introduced. Takeoff required as little as 200 feet and the plane could land at 36 mph. The prototype of final version, the CCW-5, a conversion of a pusher Baumann Brigadier executive aircraft, flew on July 13, 1953; and the first production model rolled out July 4, 1964. Despite remarkable low-speed handling and maneuvering qualities and serious interest of potential buyers, Custer could not secure enough resources to go into production. By 1964, the Beechcraft Bonanza had captured much of the business aircraft market and the vertical performance of turbine-powered helicopters overshadowed the short-field capabilities of the channel wing.
Later, Custer claimed the relative engine-to-wing placement on Republic (Fairchild) A-10 infringed on his patents but lost on grounds that both he and Republic had recognized similar airflow (natural) phenomena and incorporated them in their respective designs. Custer, a great grand-nephew of George Armstrong Custer, had been offered as much as $40 million for patents but refused, preferring to stay independent. Custer died in 1985.
