Avro Athena
The Avro 701 Athena was a British advanced trainer aircraft built by Avro in the late 1940s. It was designed to replace the North American Harvard in the Royal Air Force, but was only brought in small numbers, the competing Boulton Paul Balliol being preferred. ==Design and development== The Athena was designed to meet the requirements of Air Ministry Specification T.7/45 for a three-seat advanced trainer powered by a turboprop engine for the RAF. The Athena was an all-metal low-winged monoplane, with a side-by-side cockpit. The Air Ministry rethought its requirements in 1947 and replaced the original specification with Specification T.14/47, which specified the use of a Rolls-Royce Merlin 35 piston engine, large stocks of which were held in store.〔Jackson 1990, p. 431.〕 Despite the change in specification, the first three prototypes were of the turboprop-powered Athena T.1, the first of which, powered by an Armstrong Siddeley Mamba engine, flew on 12 June 1948 at Woodford Aerodrome.〔Jackson 1990, p. 432.〕 The Merlin-powered Athena T.2 first flew on 1 August 1948,〔Thetford, Owen. Aircraft of the Royal Air Force 1918-57, 1st edition London: Putnam, 1957.〕 and was evaluated against the similar Boulton Paul Balliol. A small production run of 15 Athenas was ordered for the RAF, but the Balliol was preferred, and no further Athenas were ordered.
