King Air C 90 GTi

 

The Beech Model 90 King Air is a light multipurpose aircraft developed by the American company Beech Aircraft. In 1963, Beech began to conduct flight tests of the aircraft, which later received the designation BeechQueenAir Model6580. It was seen as a continuation of the QueenAir type and was developed for the US Army as a general purpose transport or command aircraft. Its designation led to some confusion, since the aircraft models 80 and 65 QueenAir were still produced. Therefore, the aircraft was temporarily designated Model 6590T (the letter T stands for "turboprop"). Then one more step was taken to clarify this situation, and all aircraft of the QueenAir series with a turboprop engine were renamed to KingAir.

As a result, the 6590T aircraft became the prototype for the Beech Model 90 King Air series, more precisely, the prototype of the King Air military non-pressurized aircraft. After the first flight of the 6590T model, a civilian version was designed with a pressurized cabin. Its production prototype, designated Model90 King Air, took off for the first time on 20.01.1964/XNUMX/XNUMX.

These aircraft marked the beginning of the three thousandth series of the King Air. Tests of the 6590T model, which were conducted by the US Army (where it had the designation NU8F), demonstrated full compliance with all the necessary requirements. As a result, the first order for 48 aircraft followed under the designation U21A. The plane could accommodate a crew of two and 10 servicemen, or 6-8 command personnel, or 3 stretchers. At the same time, the chairs were easily removed and there was a place for the location of cargo weighing up to 1361 kg. The first deliveries of U21A Ute production aircraft started on 16.05.1967. As a result, contracts followed and more than 160 vehicles were built. These included U21A models, RU21A / RU21D models with Pratt & WhitneyCanadaPT6A20 turboprop engines, shaft power 550hp. and models RU21B / RU21C / RU21E with PT6A29 engines, shaft power 620 hp.

RU21 plane was specially designed for use in Southeast Asia, as an electronic intelligence. He had a set of antennas and sensors on the fuselage, and inside - appropriate systems and avionics and navigation systems that provide all-weather operation. RU21B and RU21C had from the company designation Beech Model65A902 and Model65A903 respectively, and assigned the designation U21G 17 aircraft, which were intended for the US Air Force, and were similar to the planes U21A.

Deliveries civilian version 90KingAir, which had a pressurized cabin, and up to ten seats, including pilot, started at the end of 1964. In the early 1966 the aircraft supplanted model KingAirA90, on which was mounted a more powerful motors RT6A20. One of these aircraft was used by the military code VC6A.

The next A90 was the King Air B 90, which had minor improvements, and in September 1970, the King Air C 90, which was equipped with more advanced cabin heating and air conditioning systems. The S90 aircraft was in serial production during 1982, with approximately 1000 of these aircraft manufactured. One of them, coded VC6B, was also in service with the US Air Force. Since its inception, the C90 aircraft has been constantly improving, with the PT6A21 engines mounted on it.
