Black Dog A48061 OH-58 D Kiowa engine for Italeri

Allison T63 (alternate designation: Allison Model 250 ) is an American turbo-shaft engine from the Cold War and modern times. Its first successful start-up took place in the early 1960s. The main manufacturer of these engines was the Allison Engine Company (now owned by Rolls-Royce Corporation), with total production in excess of 30,000 units. In the T63-A5 version, this motor is 1.03 meters long with a diameter of 0.57 meters. The "dry" weight of this type of engine does not exceed 62 kilograms. The engine in this version is able to generate a maximum power of 250 HP. The presented engine was developed at the request of the US Army, which wanted to acquire an engine that would be the main propulsion unit for a new, light observation plane, which was to replace the Cessna O-1A Bird Dog machine. It is worth adding that the engine from the very beginning was developed in both turboshaft and turboprop versions. We also tried to achieve the lowest possible weight, while maintaining the highest possible power and long service life. Actually, all these assumptions were met and a very successful, light and widely used aircraft engine was created. Various versions of this engine were used on such airplanes and helicopters as, for example: Britten-Norman BN-2T, GAF Nomad or Hughes OH-6 Cayuse or PZL SW-4 Puszczyk.
