Bristol Type 146
The Bristol Type 146 was a British single-seat, eight-gun fighter monoplane prototype built to a mid-1930s Air Ministry contract. Powered by a radial engine, it was outclassed by Merlin-engined fighters and only one was built.
==Design and development==
The Bristol 146 was built by Bristol to an Air Ministry order for a prototype single-seat eight-gun fighter meeting Air Ministry specification F.5/34 issued in 1934. The specification further called for an air-cooled engine for overseas use. The Type 146 incorporated the experience of metal-skinned monoplanes that Bristol had gained with the earlier Type 133, but was quite different in detail.
The Type 146 was a low-wing cantilever monoplane with tapering wings of moderate dihedral on the outer sections. The wings were stress skinned with aluminium with only the ailerons and tail control surfaces fabric-covered. The two sets of four Browning machine guns were housed in the outer wing sections. The undercarriage was mounted about halfway along the centre section and retracted cleanly inwards into the wing; the tail wheel was also fully retractable. In contrast to the Type 133, the fuselage was a monocoque structure. The cockpit was enclosed with a one-piece sliding canopy.〔
The Type 146 was designed to be powered by a supercharged Bristol Perseus sleeve valve radial engine, but this was not ready and the older, lower-horsepower Mercury IX was used instead.〔
