Lioré-et-Olivier LeO 452
The Lioré-et-Olivier LeO 452 was the designation given to a version of the LeO 45 medium bomber that was to be powered by two Hispano-Suiza 14 AA 12/13 engines (variously quotes as providing 1,100 or 1,150 hp). One pre-production LeO 452 was ordered in May 1937, but tests with the prototype revealed overheating problems with the Hispano-Suiza engines. The prototype was re-engined with Gnome-Rhone radial engines, and in the summer of 1938, after successful tests with the new engines, all existing production orders were changed to ones for the Gnome-Rhone powered LeO 451.
