[1][2] Breguet had previously had some success with two helicopter designs, one of which had been exhibited at the Paris Aero Salon in December 1908.
The engine was mounted at the front of the aircraft in a square section nacelle projecting forwards from the lower wing, driving a three-bladed propeller.
The wings were connected by four steel tube interplane struts, each enclosed in a streamlined fairing.
The machine was displayed without an engine at the Olympia Aero Show in London in March 1909[3] and first took to the air on 28 June at La Brayelle Airfield.
[2] Bréguet flew this aircraft, given the exhibition number 19, at the Grande Semaine d'Aviation in August,[4] but crashed when the machine was caught in a gust of wind .
