Template:Infobox Aircraft The Hawker Hawfinch was a British single engined biplane fighter of the 1920's. It was unsuccessful, with the Bristol Bulldog being selected instead.
Development
The Hawker Hawfinch fighter aircraft was designed in 1925 as a replacement for both the Armstrong-Whitworth Siskin and the Gloster Gamecock fighters. It participated in the competition to meet Specification F9/26, together with other aircraft manufacturers, that included nine different designs, of which five were built [1]. The Hawfinch first flew in March 1927 [2]. The Bristol Bulldog and the Hawfinch were considered to be the best of the aircraft evaluated, and were selected for more detailed evaluation. The contract was finally awarded to the Bristol Bulldog, because of its slightly higher maximum speed. After the completion of the competition, the prototype Hawfinch was used for experimental purposes, being tested with single bay wings and with a twin float undercarriage.
Only one prototype was built.
Description
Twe Hawfinch was a two bay biplane with staggered wings. The structure was the patented Hawker metal tube & "fishplate" system, with fabric covering. It was the first all-metal fighter to be built by Hawker. The powerplant was initially a Bristol Jupiter VI engine, but this was changed to a Jupiter VII (450 hp) before the performance trials. The armament consisted of two Vickers machine guns synchronised to fire through the propeller.
