Design and development

The Bernard 82 was developed from the long-range Bernard 80 GR, which had been designed to set long-distance-flight records.[1] The all-metal Bernard 82 was a three-seat long-range bomber, known at the time as a bombardier de represaillies or reprisal bomber.[1] The cantilever mid-wing monoplane was powered by an 860 hp (641 kW) Hispano-Suiza 12Ybrs inline piston engine.[1] The first prototype flew from Le Bourget on 11 December 1933, and in March 1932 was joined by the second prototype.[1] Flight testing showed the twin lateral radiators to be inadequate; they were replaced by front-mounted radiators. Landing-gear deficiencies were the most persistent difficulty encountered during testing.[1] The retractable landing gear regularly failed; resulting in wheels-up landings. The problem was never resolved, and testing was halted in mid-1935; the production contract for ten aircraft was cancelled.[1]

In August 1936 the second prototype was re-engined with a 650 hp (485 kW) CLM Lille 6As, a licence-built Jumo 205 diesel engine.[1] The diesel-powered aircraft, redesignated Bernard 86, was entered into the 1936 Paris-Saigon-Paris air race. The race was run in September, but the Bernard was not ready by then, so it was not used. There were no further flight tests; the units were scrapped.[1]
