Blackburn B-54
The Blackburn B-54 and B-88 were prototype carrier-borne anti-submarine warfare aircraft of the immediate post Second World War-era developed for the Royal Navy's Fleet Air Arm (FAA). They shared a conventional monoplane design with a mid-mounted inverted-gull wing and tricycle undercarriage. The pilot and observer sat in tandem under a long canopy atop the fuselage. The B-54 had a piston engine and the B-88 a gas turbine driving a large contra-rotating propeller. The radar scanner was mounted in a retractable radome in the rear fuselage, behind a long internal weapons bay. The program was cancelled in favour of the Fairey Gannet aircraft.
==History==
The B-54, or Y.A.5, was designed to meet Specification "G.R.17/45" for an advanced carrier-borne anti-submarine aircraft by Blackburn Aircraft. Rivals Fairey designed their Fairey 17 to the same specification, which would eventually evolve into the winning design, the Fairey Gannet. The original Y.A.5 was designed to take the new Napier Coupled Naiad turboprop engine, consisting of two single Naiads driving a contra-rotating propeller through a common gearbox. This engine was ultimately cancelled, so the Y.A.5 flew as the Y.A.7 with a Rolls Royce Griffon 56 piston engine driving a contra-rotating propeller. This aircraft made its maiden flight on 20 September 1949 ahead of the compteting Fairey design. In 1950, the Admiralty added the requirement for a radar and radar operator to the specification. The Y.A.7 was further refined into the Y.A.8, first flying on 3 May 1950, with aerodynamic refinements to improve handling and the third crew position. The Y.A.8 design was used as the basis for the B-88 Y.B.1 which first flew on 19 July 1950. The B-88 had an Armstrong Siddeley Double Mamba engine similar in design to the original Naiad that was to be fitted to the Y.A.5. Development of this design was protracted and the FAA lost interest in favour of the promising Fairey Gannet, which had already flown with the Double Mamba and carried out landing trials, and which was to enter operational service fulfilling the original specification.
