The '''Blackburn B-54''' and '''B-88''' were prototype [[aircraft carrier|carrier-borne]] [[Anti-submarine warfare]] aircraft of the immediate post [[World War II|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 gear|tricycle undercarriage]]. The [[aviator|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 [[turboprop|gas turbine]] driving a large [[contra-rotating propellers|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.

Number built 3

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.

Design[]

The B-54 / B-88 shared a common airframe. It was a large, single-propeller conventional monoplane with a mid-mounted, inverted-gull wing and a mid-mounted horizontal tail-plane with considerable dihedral. Unlike the Fairey Gannet, it had a simple wing folding mechanism that split once at the angle of the gull-wing. The deep fuselage accommodated the engine(s), a large weapons bay and the crew of two were seated high up in tandem under a single canopy (the third crewman in the Gannet was specified after the cancellation of the Blackburn design). The undercarriage was a conventional tricycle type and a radar scanner was carried in the rear fuselage in a retractable dome, much like in the Fairey Gannet.

Engine[]

After the cancellation of the Napier Naiad programme, the prototype was fitted with the readily available Rolls-Royce Griffon 56 engine, delivering 2,000 hp (1,491 kW) to a 13 ft (4 m), six-blade (two three-bladed propellors) contra rotating propeller mechanism. In the B-88, an engine plant based on the Armstrong Siddeley Mamba gas turbine; the Double Mamba - also known as the "Twin Mamba" - driving an eight-blade counter-rotating propeller through a common gearbox. The ASMD.1 engine used on the B-88 was rated at 2,950 hp (2,200 kW).
