The Bristol Racing Biplane was a British single-seat biplane designed to combine the performance of a monoplane but using the strength of the biplane. It was designed by Robert Grandseigne and Léon Versepuy, who were supervised by George Challenger for the British & Colonial Aeroplane Company of Bristol, it crashed on its first flight.[1]

Design and development[edit]

The Racing Biplane, also known as The Racer or Biplane No. 33 from its Bristol sequence number, was powered by a 50 hp (37 kW) Gnome engine driving a four-bladed tractor propeller.[1] It had unequal span wings each with a single steel-tube spar.[1] The rectangular fuselage was a composite structure of wood and steel tubes covered in fabric. It had a twin-skid steel-tube chassis fitted with two wheels on a rubber-sprung cross axle and also had a tail skid, the main skids were long enough to act as brakes on landing.[1] The aircraft was displayed at Olympia in 1911 and was then taken to Larkhill in April 1911 where it was wrecked when it overturned attempting its first flight.[1]
