Breguet 892S Mercure

 

With a French Air Force requirement to replace the Douglas C-47 and Amiot AAC-1, in 1948, Breguet came to the conclusion that in the near future a high capacity transport aircraft would be needed that could be used for by both civilians and military.


Prototype 890J Mercure commercial transport was originally to be powered by two Jumo 211 but with the availability of the British Hercules engine the designation was changed to 890H.


The prototype of the basic model Breguet Br.890H Mercure is a cantilever monoplane with a high-wing, construction - all metal, except fabric covering control surfaces of the empennage. The power plant consisted of two Bristol Hercules 739 engines rated at 2000 hp. The aft fuselage contains a swing tail to allow access. On the ceiling of the cargo compartment rails fastened to the lift / winch designed for the download directly from the truck through the back as well as through a side door. It had a retractable tricycle landing gear. One was built and first flown in April 1950.


Br.891R Mars was a military transport version of Br.890H Mercure, retained the structural features of the latter, but distinguished by folding the seats for 20 paratroopers laid along the sides, and doors on the sides for dropping paratroopers in the air, as well as the hatch to clear the cargo container, and fixing landing site for towing gliders. The power plant consisted of two Gnome-Rhone 14R-200 rated at 1600 hp (1,193 kW). One was built and first flew in November 1949.


The first to fly on 1 March 1949, the Breguet 892S Mercure had four 500 hp (373 kW) Renault 12S inline piston engines. A convertible cargo/passenger variant, one was built and the 892S was later converted to be the second 890H.


Only one prototype of each variant was built, the French Air Force ordered the Nord Noratlas rather than the Mars and with the availability of war-surplus aircraft like the Douglas DC-3 available to commercial operators the type did not enter production.
