Avro Ashton
The Avro 706 Ashton was a British prototype jet airliner made by Avro during the 1950s. Although it flew nearly a year after the de Havilland Comet, it represented an experimental programme and was never intended for commercial use.
==Design and development==
The Avro 689 Tudor 9 was based on the Avro 689 Tudor II piston-engined airliner using experience on work on the Rolls-Royce Nene jet-powered experimental variant the Tudor 8. The Avro Type 689 Tudor 9 later renamed the Avro 706 Ashton was a four-jet-engined research aeroplane powered by Rolls-Royce Nene engines paired in wing nacelles.
Six were built using the Tudor airframe, beginning with the conversion of Tudor I initially powered by Nene 5 engines. The Ashtons that followed incorporated the upgraded Nene 6 and featured an enlarged, "square-shaped" tail fin and tricycle landing gear replacing the original "taildragger" configuration. The engines were tightly grouped in two nacelles that were faired neatly into the wing but also extended below in streamlined pods. The four-engine arrangement compensated for the low thrust of the early jet engines and greatly reduced asymmetric affects in an "engine-out" scenario.〔Jackson 2000, p. 435.〕
The crew was composed of a pilot, co-pilot, navigator, flight engineer and radio operator clustered together in the cockpit and front compartment of the Ashton. A larger complement could be carried in the spacious fuselage when warranted.
