Westland Aircraft was a British aircraft manufacturer located in Yeovil, Somerset. Formed as a separate company by separation from Petters Limited just before the start of the Second World War, Westland had been building aircraft since 1915. During the war the company produced a number of generally unsuccessful designs, but their Lysander would serve as an important liaison aircraft with the Royal Air Force. After the war the company focused on helicopters, and was merged with several other British firms to create Westland Helicopters in 1961.
In 1915 the Westland Aircraft Works was founded as a division of Petters in response to government orders for the construction under licence of initially 12 Short Type 184 seaplanes, followed by 20 Short Admiralty Type 166. Orders for other aircraft followed during First World War, including the Sopwith 1½ Strutter, the de Havilland designed Airco DH.4, Airco DH.9 and Airco DH.9A and the Vickers Vimy. The name "Westland" was chosen by Mrs Petter as new land purchased as part of an expansion in 1913 at West Hendford which had been earmarked for a new foundry, but ended up becoming the centre for aircraft production. As a result of the experience gained in manufacturing aircraft under licence, Westland began to design and build its own aircraft, starting with the Westland N.1B in 1917, which was followed in 1918 by the Wagtail and the Weasel.
Following the end of war, Westland produced the Limousine and Woodpigeon light aircraft for the civilian market, but most successful was the Wapiti close support aircraft. In 1935 Petters split its aircraft manufacturing from its aircraft engine concerns to form Westland Aircraft Limited, based in Yeovil, Somerset.
The Whirlwind was the UK's first cannon-armed fighter and faster than many other British aircraft at the time but was troubled by the inability of Rolls-Royce to produce the engines. The Lysander army co-operation aircraft was displaced for reconnaissance as too vulnerable but found favour for specialist missions into occupied Europe carrying agents. Westland tendered designs for new aircraft during the war but only the Welkin was accepted. The Welkin was a twin-engine high altitude design to intercept attempts by high-flying German bombers to attack Britain. When the threat never appeared production was limited.
For much of the war their factories were used to build Supermarine Spitfires, after the Supermarine factory in Southampton was bombed out of action during the Battle of Britain; indeed Westlands built more Spitfires than any other manufacturer. Westland would then go on to be the major designers of the Supermarine Seafire, a navalised conversion of the Spitfire.
The Westland Wyvern was a post-war design of carrier-based strike-fighter for the Fleet Air Arm serving up to 1958.
Post-war the company decided to get out of fixed-wing aircraft and concentrate solely on helicopters under a licensing agreement with Sikorsky. This upset W.E.W. Petter, the chief designer, who left to form a new aircraft division at English Electric that would go on to be very successful.
Production started with the Sikorsky S-51 flying for the first time in 1948 and as the Westland-Sikorksy Dragonfly entering service with the Royal Navy and RAF from 1950. Westland developed an improved version the Widgeon which was not a great success. Success with the Dragonfly was repeated with the Sikorsky S-55 which became the Whirlwind, and a re-engined Sikorsky S-58 in both turboshaft and turbine engine powered designs as the Wessex.
In 1952 Westland decided on four helicopter designs for possible development:
None of these Westland helicopters advanced further than the paper study. Westland did progress as a private venture, a large space-frame cargo helicopter design using a Sikorksy rotor head - the Westland Westminster - but this was dropped later in favour of the government funded Fairey Rotodyne.
From 1959 to 1961 the British government forced the consolidation of 20 or so British aviation firms into three larger groups with the threat of withheld contracts and the lure of project funding. While the majority of fixed-wing aircraft design and construction lay in the British Aircraft Corporation and the Hawker Siddeley Group, the helicopter divisions of Bristol, Fairey and Saunders-Roe (with their hovercraft) were merged with Westland to form Westland Helicopters in 1961.
Normalair was created to continue the development and marketing of the pressure relief valves used in the Welkin project.
