Nieuport Nighthawk
The Nieuport Nighthawk was a British fighter aircraft developed by the Nieuport & General Aircraft company for the RAF towards the end of the First World War.
The Nieuport & General Aircraft Co. Ltd. was formed on 16 November 1916 to produce French Nieuport aircraft under licence.During 1917,Henry Folland was hired as chief designer, the company started to design its own aircraft, with the first type, the Nieuport B.N.1 fighter (the designation signifying British Nieuport) flying early in 1918.
Folland designed the Nighthawk, a wooden two-bay biplane to be powered by a new Dragonfly engine.. An initial order for 150 Nighthawks was placed in August 1918,before prototypes or flight-ready engines were available, with the first prototype,flying in April or May 1919.
By this time, it was clear that the Dragonfly engine had serious problems, being prone to extreme overheating, high fuel consumption and severe vibration.When the engine did operate as planned to, the Nighthawk showed excellent performance, but in September 1919, it was finally recognised that the Dragonfly was unsalvagable and the engine programme was cancelled, although by this time 1,147 engines had been delivered.
In an attempt to work out the problems with the Dragonfly engine, four Nighthawks were also retained by the R.A.E. with trials carried out in 1920–21.Nieuport & General closed down in August 1920, and the rights to the Nighthawk were purchased by the Gloster Aircraft Company, who also hired Folland as chief designer. Gloster proceeded to produce a number of derivatives of the Nighthawk, using stocks of Nighthawk components acquired by the company from the cancelled production run, calling them the Gloster Mars.
The Gloster Nighthawk, or Mars VI, replaced the Dragonfly with either an Armstrong-Siddeley Jaguar or a Bristol Jupiter radial. In 1922, the RAF acquired 29 aircraft converted from Nieuport Nighthawks, powered by both Jaguar and Jupiter engines, while Greece purchased 25 Jaguar powered fighters.
