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. ==Design and development== The Dreadnought was distinct for its futuristic design and method of construction, based on the theories of the Russian inventor N. Woyevodsky. After preliminary tests of the idea were tried in a wind tunnel and met with some degree of success, the design was given to Westland Aircraft to construct an aircraft. The design at the time was for a 70 ft wingspan twin-engine aircraft. 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.〔("Dreadnought." ) ''aviationarchive.org''.
