Operational Context
The American manufacturing company Curtiss-Wright developed the CW-25 prototype with fuselage and tail surfaces covered in fabric upon anticipating the need for a high-performing aircraft powered by twin engines. The prototype was built with the characteristics of a light bomber in taking off and landing.
In 1941, it took to the air for the first time. In 1942, the production variant designated as AT-9 entered into service. The manufacturing company gave the aircraft the name “Fledgling”; however, it became more popular with the United States Army Air Forces designation “Jeep”. The AT-9A version was powered by two Lycoming R-680-11 radial engines and equipped with a modified hydraulic system. The Jeep was produced until 1943 with a total number of 792 aircraft built including prototype and AT-9A versions.
The AT-9 is a two-crew production version with an external length of 9.65 meters, an external height of 2.4 meters, and a fuselage diameter of 1.5 meters. It has a tail height of 3 meters and a wheelbase of 6.6 meters. The wingspan is 12.29 meters and the wing area is 21.6 square meters. The aircraft has an empty weight of 2,038 kg and a gross weight of 2,749 kg.
The AT-9 is powered by twin Lycoming R-680-9 engines. It is a nine-cylinder air-cooled radial engine with one inlet and one exhaust valve per cylinder at 30 degrees, a single-barrel carburetor, a full pressure type oil system, and an air cooling system. The engine produces a maximum thrust of 295 hp each and drives two-bladed propellers. It has a maximum speed of 171 knots and a cruise speed of 152 knots. The travel range is 650 nautical miles. It can fly up to 19,000 feet and can climb at a rate of 1,175 feet per minute.
