Breguet 14 - Design and Development

Design and Development

The aircraft was designed by Louis Breguet, who flew the first prototype (originally designated Breguet AV Type XIV) on its first flight on 21 November 1916. The design was a come-back for Breguet to designing conventional planes, after designing pusher-type aircraft Breguet BUM. Later that month, the French Army's Section Technique de l' Aéronautique (S.T.Aé.) issued requirements for four different new aircraft types. Breguet submitted his new design for two of those categories - reconnaissance aircraft, and bomber.

Following evaluation in February, the Breguet 14 was accepted for both these roles, and in March, orders were placed for 150 reconnaissance aircraft and 100 bombers, designated Breguet 14 A.2 and 14 B.2 respectively (by 1918 written Breguet XIV A2/B2). The A.2 was equipped with a camera, with some carrying radios, while the lower wing of the 14 B.2 was modified slightly in order to accommodate bomb racks (built by Michelin). Both variants featured automatic, bungee-cord operated aerodynamic flaps, but these were not fitted to production aircraft. A number of B2 models were equipped with the U.S. built Liberty engine and were denoted Breguet 14 B2 L.

Other minor variants flown in small numbers during the war included the 14 B.1 long-range single-seat bomber, the 14 GR.2 long-range reconnaissance, the 14 H floatplane, the 14 S air ambulance and the 14 Et.2 trainer. Later variants 14bis A2 and 14bis B2 featured improved wing. An improved variant with bigger wings was the 16. There was also the two-seat fighter 17, which was built in small numbers only.
