Boulton Paul Balliol
The Boulton Paul Balliol and Sea Balliol were the single-engine military trainer aircraft of the British manufacturer Boulton Paul Aircraft from the late 1940s. They were commissioned by the Royal Air Force and the Royal Navy as a replacement for the North American Harvard.
History
The Balliol was in competition with the Avro Athena and met the requirements of the Air Ministry for a three-seater training aircraft with a Turbopropmotor. The all-metal aircraft was designed as a low-wing and had a retractable spur wheel chassis. Student pilot and instructor sat side by side, behind them was an additional seat
The first prototype made its maiden flight on 30 May 1947. He had initially over a Bristol Mercury radial engine 30. The second prototype of 1948 was from the beginning a Armstrong Siddeley Mamba engine.
Meanwhile, the Air Ministry had changed its requirements and required a two-seater model with a Rolls- Royce Merlin piston engine. The adapted version was given the designation Balliol T.2 and first flew on 10 July 1948. For use on aircraft carriers, the Sea Balliol T.21, which had folding wings and a tail hook was.
The Balliol occurred in 1950 in the service of the Royal Air Force. In 1951, the Ministry again changed his plans and called for a trainer aircraft with jet propulsion. On the other hand generating further Balliol was omitted. In 1956 they were replaced by the de Havilland Vampire T.Mk.11.
