From Wikipedia, the free encyclopedia

I Triplane
Type Experimental aircraft
Manufacturer Alliott Verdon Roe
Designed by Alliott Verdon Roe
Maiden flight 5 June 1909 (but sources differ as to which attempt should first be regarded as a "flight")
Number built 4

The Roe I Triplane (often later referred to as the Avro Triplane) was an early aircraft, the first all-British aircraft to fly (Roe's previous biplane had a French engine). It featured not only a triplane wing, but a triplane tail as well. It was of extremely flimsy construction; financial hardship compelled Roe to use wood for structural elements where he would have preferred steel, and the wings and fuselage were paper-covered. Roe nicknamed the aircraft The Blues after the braces manufactured by his brother's firm that had helped pay for it. Beginning on 5 June 1909, he made a series of short hops on the Walthamstow Marshes in Essex. The triplane's wings were damaged by crashes during these attempts, but Roe persevered.

On 13 July, he achieved a flight of 100 ft (30 m), and ten days later, one of 900 ft (275 m). With confidence building, he swapped the original 6 hp (5 kW) JAP motorcycle engine for a 24 hp (18 kW) Antoinette. With this engine, he piloted the aircraft on several short flights at the Blackpool Meeting in October before it was damaged beyond repair in a crash at Wembley on 24 December.

Roe constructed three more machines to this design, powering them with ever-larger JAP engines. One example is preserved at the Science Museum in London, and the Museum of Science and Industry in Manchester has a full-scale replica on display.
