Avro 584 Avocet
|FIGHTER||Virtual Aircraft Museum / United Kingdom / Avro|
The Avocet was designed to the requirements of Specification 17/25, which, issued in June 1926, called for an all-metal stressed-skin shipboard fighter with interchangeable wheel and float undercarriages and powered by a 180hp Armstrong Siddeley Lynx IV nine-cylinder air-cooled radial engine. Two prototypes were ordered, these being identical apart from the vertical tail surfaces, but for manufacturer's trials the first prototype was completed as a landplane and the second prototype as a twin-float seaplane, these flying respectively in December 1927 and April 1928. The second prototype was also fitted with a land undercarriage in June 1928. Armament comprised two 7.7mm Vickers machine guns synchronised to fire through the propeller disc. Performance of the Avocet during evaluation at Martlesham proved unspectacular and no production order was placed.
