Vickers Venom
The Vickers Type 279 Venom was a low-wing monoplane single-seat, single-engined, eight-gun fighter, powered by a radial engine. It was fast and maneuverable, but its engine lacked the power and development potential of its Merlin-powered competitors. Only one was built.
==Design and development==
The Vickers Venom〔Andrews and Morgan 1988, pp. 246–50, 254.〕 was designed to meet Air Ministry specification F.5/34 which called for a single-seat eight-gun aircraft with the high maximum speed and rate of climb needed to catch 200 mph (320 km/h) bombers flying at 15,000 ft (4,600 m). The aircraft would have to use a radial engine as it was intended to be used overseas in hot climates. Vickers based their entrant on the earlier Type 151 Jockey fighter, using the same wing and tail aerofoil sections and dimensions, but replacing the Wibault-Vickers corrugated construction of the Jockey with a modern stressed skin structure.〔Goulding 1986, p. 63.〕
The Venom (originally known as the Jockey Mk II) was a low-wing monoplane, with square tipped constant chord wings and tailplane. The fin, too, was square tipped, but the rather angular appearance did not extend to the fuselage, which tapered rearwards from the engine's long chord cowling back to the tail. The pilot sat over the wing in a perspex enclosed cockpit, which had unusual additional windows in the fuselage for an enhanced side and downwards view. The inverted U-shaped fairing behind the cockpit extended back to the base of the fin.
The fuselage was an alloy skinned monocoque structure of polygonal section, and the thicker plates of the wings were also stressed, taking the drag loads. The wings carried 90° flaps and there was a wide track, inward retracting main undercarriage plus a small fixed tailwheel. Both the flaps and undercarriage were electrically operated. The deep RAF 34 wing section eased the installation of the required eight Browning machine guns. The Venom was powered by a 625 hp (466 kW) Bristol Aquila AE-3S sleeve valve radial engine, hinge-mounted so it could be swung sideways for easy maintenance. The Aquila drove a three-bladed propeller. Joseph "Mutt" Summers flew the Venom on her first flight, 17 June 1936. Unlike the Hurricane and Spitfire, the Venom was fitted with full armament from its first flight.〔Mason 1992, p. 265.〕
