Bristol Type 84 Bloodhound
The Bristol Bloodhound was a British two-seat reconnaissance/fighter aircraft designed as a possible replacement for the Bristol F.2 Fighter for the Royal Air Force. It was unsuccessful and only four prototypes were built.
The first prototype was fitted with a Jupiter V engine, and received a civil certificate of airworthiness before being flown in the 1925 King’s Cup Race. It was then fitted with a Jupiter VI engine and long-range fuel tanks as an engine testbed, proving the reliability of the Jupiter for Imperial Airways before finally being scrapped in 1931.
