Westland Widgeon: An Overview
The Westland Widgeon was a British light aircraft that emerged in the 1920s, representing the era’s burgeoning interest in civil aviation. This single-engined parasol monoplane was developed during a time when the British Air Ministry sought to promote affordable aircraft for private owners and flying clubs. Although production was limited and ultimately ceased in 1929, the Widgeon left an indelible mark on aviation history with its unique design and performance capabilities.
Development and Design
The development of the Westland Widgeon began in 1924, when the British Air Ministry initiated a competition aimed at stimulating the creation of inexpensive civil aircraft. The criteria specified that the aircraft must be a two-seater capable of carrying a payload of at least 340 pounds (150 kilograms) and powered by an engine with a displacement of no more than 1100 cc. In response to this challenge, Westland Aircraft produced two designs: the Woodpigeon biplane and the Widgeon parasol monoplane.
Despite their initial enthusiasm, Westland faced a dilemma in choosing which design would be superior. Consequently, they decided to build both aircraft. The first flight of the Widgeon took place on September 22, 1924, just eight days after the Woodpigeon’s maiden flight. The Widgeon featured a fuselage constructed from a combination of steel tubing and wood, while its distinct wooden parasol wing was designed to fold for easy storage. It was powered by a Blackburne Thrush three-cylinder radial engine capable of producing 35 horsepower (26 kW).
However, during the Light Aircraft competition that commenced at Lympne Aerodrome on September 27, the Widgeon struggled due to its underpowered engine. It crashed on the first day of trials but still demonstrated potential superiority over the Woodpigeon. Following this setback, Westland rebuilt the aircraft, upgrading it to include a more powerful Armstrong Siddeley Genet engine rated at 60 horsepower (45 kW). This transformation significantly improved performance, increasing speed by nearly 40 mph (64 km/h).
Competitive Performance
The newly configured Widgeon II participated in the prestigious Grosvenor Cup air race on September 18, 1926. During this event, it achieved an impressive average speed of 105 mph (169 km/h), which was the fastest recorded speed in that race. However, due to a handicapping system in place at the time, the race was ultimately won by a Blackburn Bluebird rather than the Widgeon II.
Despite its promising performance, only one unit of the Widgeon II was produced and later sold in January 1928. Tragically, this aircraft met with disaster when it was involved in a fatal crash on October 10, 1930.
Transition to Production
Building upon the insights gained from their earlier prototypes, Westland decided to enter into production with a redesigned version of the Widgeon aimed at private owners. This iteration led to the creation of the Widgeon III, characterized by its simpler constant chord wing that replaced the tapered wing design used in previous models. This change streamlined production and made assembly easier.
The first flight of the Widgeon III occurred in March 1927, with production commencing later that year. To further enhance its design, Westland introduced a duralumin tube fuselage along with a new undercarriage configuration for improved performance and durability. The Widgeon III could accommodate various engines for flexibility; it could be powered by either a radial engine like the Genet or an inline engine such as the Cirrus.
Widgeon IIIA and Production Challenges
The final variant produced was known as the Widgeon IIIA. This version featured further refinements including a metal fuselage and an updated undercarriage design. It utilized either Cirrus or de Havilland Gipsy engines for power. In total, seven units of this variant were built.
Despite its innovative features and capabilities, production numbers for all variants of the Widgeon remained low due to high manufacturing costs compared to competing aircraft of similar roles. Ultimately, only 26 units across all types were constructed before Westland ceased production in 1930. The decision to halt production allowed Westland to redirect its resources toward other projects such as the Wapiti general-purpose military aircraft and the Wessex airliner.

Conclusion
The Westland Widgeon stands as a testament to early British aviation efforts during a transformative period for civil aviation. Although production numbers were modest and its operational life was cut short by various challenges, its innovative design elements and competitive spirit contributed significantly to aviation development in Britain during the late 1920s. Today, it remains an interesting chapter within aviation history as enthusiasts remember both its achievements and shortcomings.
