Roe I Triplane
Avro Triplane is the better known name for triplane aircraft of the British aircraft designer Alliott Verdon Roe.
History of development
After AV Roe initially a biplane, the Roe I, had designed and built, he built a single-seat triplane, a paper- covered wooden construction. The hull had a triangular cross-section and was not covered. The outer 1.52 m of the wings could be solved for the transport and fold. The drive initially served a 9 hp ( 6.7 kW) Japanese engine. It is worth mentioning that the structure in the rear of the machine was performed in triplicate. On June 5, 1909, the machine in Essex made on the Lea Marshes the first jumps and managed on 23 July of the same year a flight of 274 m length. Shortly thereafter, the aircraft received a 24 hp (18 kW) Antoinette engine. At the October meeting in Blackpool reach several short flights. Roe managed the plane to Wembley, where it crashed on 24 December 1909. Roe presented three additional copies of the triplane I with 9 hp ( 6.7 kW ), 20 hp ( 15 kW) and 35 hp (26 kW) JAP Engines.
In April 1910, the successor model, the II with a more powerful engine, a JAP engine with 26 kW (35 hp). Launched This guy was covered with fabric instead of paper. The machine has been exhibited in July 1909 without a motor at the Olympia Travel Exhibition. Despite the more powerful engine put the aircraft in the longest flight only 183 meters back. It was dismantled in 1910.
After Roe offered at a retail price of 600 pounds sterling to another three-decker with the name Mercury. There was a plywood -clad two-seater, which was by a 35- hp ( 26 kW ) Green engine driven strong with a two -blade propeller.
A further development was the Avro Triplane No. 3 ( Roe III ), also a two-seat aircraft, but much more stable build than its predecessor, also equipped with ailerons; the roll control was still on Flächenverwindung with the predecessors. The Triplane No. 3 had its maiden flight on 24 June 1910.
The specimens Nos. 2 and 3 of the triplane No. 3 began during a rail transport to air shows, to be held in July and August 1910 in Blackpool, fire caused by sparks from the engine and burned. Roe therefore used for this event, the fourth copy which was in a hurry from parts that came from Manchester, assembled.
A total of triplane No. 3 six copies produced in Manchester. The last two Triplanes No. 3 were built for the Harvard Aeronautical Society and Cecil Grace.
In September of 1910, appeared the only copy of the single-seat triplane No. 4 ( Roe IV), such as No motorized. 2 and 3 Control is achieved by wing twist. The fuselage had a triangular cross-section again and was dressed in the front area with a thin aluminum sheet. At the rear, there was a relatively large tailplane with massive rowing.
