Note: This is a sub-section of Westland Aircraft.
The Westland Dreadnought was an experimental single-engined fixed-wing monoplane design for a mail plane created to trial the aerodynamic wing and fuselage design ideas of Woyevodsky. It was designed and built by British aircraft manufacturer Westland Aircraft for the Air Ministry. Only a single aircraft was ever built, and it crashed on its initial flight, badly injuring the test pilot.
The design was aerodynamically advanced, featuring a continuous aerofoil section over all parts of the aircraft, including the fuselage and, unusually for British aircraft at that time, had no form of wing bracing.
Construction was all-metal, comprising drawn channeling with a skin of corrugated sheet panels. The method may be compared to the modern stressed skin construction.
Another advanced feature was the fail-safe ejection system.
Although conceived as a twin-engined type with retractable undercarriage, the design that emerged was fitted with a single 450 horsepower Napier Lion II 12 cylinder engine that allowed the Dreadnought speeds of up to 102 miles per hour.
