Breguet 27/270 Series
The Breguet 27 was a 1930s French biplane military reconnaissance aircraft, built for French Air Force and for export to Venezuela and China.
The Bréguet 27 was designed in response to a 1928 request for proposals by the Armée de l’Air for a two-seat observation aircraft to replace the Bréguet 19.
Bréguet submitted a large all-metal sesquiplane with an unusual fuselage that ended abruptly, aft of the two open cockpits.
The empennage was mounted on a boom behind the fuselage. Construction was largely of steel tubing with non-structural aluminium alloy sheeting and fabric covering for wings and empennage.
The prototype exhibited mediocre performance during flight trials.
Nonetheless the military placed orders for 85 aircraft in 1930 and 45 in 1932, this latter batch having a more powerful engine fitted.
Two high-altitude reconnaissance versions were also built as the Breguet 33, but these did not lead to further production.
A single Bre.27S was constructed, modified from the Bre.330 No.2, powered by a single Hispano-Suiza 12Nb engine.
Prototypes (ten built) and initial production version (143 built) powered by a single Hispano-Suiza 12Hb engine.
Version powered by the Hispano-Suiza 12Y engine, 45 built.
Version powered by the Gnome-Rhône 9Kdrs engine, two built.
(Théatres des Operations Extérieures) Version optimised for harsh colonial conditions with Renault 9Fas radial engine, 1 built.
Reconnaissance-bomber variant for export, powered by a Hispano-Suiza 12Ybrs engine, 13 built and one converted from a Bre 270.
Ten more were built for China powered by Hispano-Suiza 12Ydrs engines, with three also being modified from Hispano-Suiza 12Ybrs powered versions.
Version powered by the Gnome-Rhône 14Kdrs engine, raced by Maryse Hilsz in 1936, one built.
High-altitude version of Breguet 27 with Hispano-Suiza 12Nb engine, one later redesignated Bre.27S, two built.
Second Bre.330 prototype optimised for long-duration flight.
