Bristol B.93 Boarhound / Bloodhound

Bloodhound

Designed by Wilfrid T Reid to meet Air Ministry Specification 3/22 issued in June 1922 for a two-seat fighter, the Bloodhound was flown for the first time at the end of May 1923. Featuring a welded steel-tube fuselage and wooden wings, and powered by a 425hp Bristol Jupiter IV engine, the Bloodhound carried an armament of two synchronised 7.7mm Vickers machine guns and a 7.7mm Lewis gun on a Scarff mounting on the rear cockpit. Three additional Bloodhounds were built to the order of the Air Ministry, the first of these being of all-metal construction and the others having wooden wings and tail. All three were powered by the Jupiter IV, but the engine of the third aircraft was fitted with an RAE supercharger. The three aircraft were delivered to Martlesham and Farnborough between March and September 1925, but no production was undertaken.
The original prototype was successively fitted with the Jupiter V and VI, and served primarily as an engine test bed.

Boarhound

In 1927 a Mexican purchasing commission placed contracts in the UK for 10 new Hispano-Suiza engined Bristol Fighters and two Type 93B Boarhound II reconnaissance fighters.

Bristol B.72 Racer

The Bristol 72 Racer was designed in 1922, by engineer Wilfrid Thomas Reid. It has a cylindrical monocoque fuselage and retractable landing gear. Of mixed construction wood and metal for the fuselage, the wings fabric covered. Power way provided by a Bristol Jupiter IV of 480 hp.

Controlled by Mr. FC Uwins, it first flew in June 1922. The Racer encountered many problems with instability. Envisaged entering the Aerial Derby of 1922, it was painted red, registered G-EBRD, and given the number 10, it did not take part as it was not ready. With continuing difficulties with development, it was abandoned in 1924 after having flown only 8 times.

Bristol Tourer

The Bristol Tourer was originally a conversion of the Bristol F.2b Fighter built for and flown by the RAF in World War I. At the end of the war a number were converted in the UK as low-cost commercial airliners, fitted with a 134 kw (180 hp) Wolseley Viper, 179 kw (240 hp) Siddeley Puma, or 224 kw (300 hp) Hispano Suiza engine. Four distinct conversions were built, all flown from the front seat, varying in type of accommodation provided for the passengers, ie an enclosed cabin or open cockpit. Bristol type-numbers 27, 28, 29 and 47 were allotted to the series in 1923.

The first conversion was flown in 1919 and another was shown at the Paris Salon in December of that year. Two were sold in the USA and two others were fitted with floats. Two went to Spain and eight to Australia.

Bristol TTA

Designed by Frank Barnwell assisted by Leslie G Frise, the T.T.A. (Twin Tractor Model A) was intended to meet a requirement for a two-seat twin-engined local defence fighter, the gunner in the nose having an unobstructed field of fire for two free-mounted 7.7mm Lewis guns. Dual controls were fitted and the intended power plant comprised two 150hp R.A.F.4a engines. In the event, non-availability of these engines resulted in the installation of two 120hp six-cylinder Beardmore water-cooled engines in the two prototypes ordered. The first T.T.A. was flown in April 1916, but displayed poor lateral control and was adversely criticised on the grounds of poor pilot view. As by this time synchronising mechanisms for guns were becoming available, no further development of this category of aircraft was pursued.
