Design and development
editRomanian Henri Coandă, chief designer of the Bristol Aeroplane Company, developed the P.B.8 as a biplane trainer to replace the early Bristol Boxkite at the Bristol flying school at Brooklands, it was the only biplane designed by Coanda.[1] It was small biplane with equal span wings with ailerons on both the upper and lower wings.[1] The small cockpit had room for two in tandem, although access to the rear seat was restricted by the upper wing.[1] It inherited an unusual four-wheel landing gear from other Coanda designs like the T.B.8.[1] The aircraft was powered by an 80 hp (60 kW) Gnome Lambda engine fitted at the rear of the cockpit nacelle and driving a pusher propeller.[1]
The design was started November 1913 but its construction was a low priority for the company and the completed aircraft was not delivered to Brooklands until July 1914.[1] The Gnome engine was requisitioned by the war office and removed from the aircraft before it had a chance to fly.[1]
