Editing SNCASE Armagnac (section)

==Design and development==
Designed originally around a French requirement for an 87-passenger, long range airliner issued in 1942, the S.E. 2000 was to have been powered by four 2,100&nbsp;hp [[Gnome-Rhône]] 18R engines. At an early stage, the S.E. 2000 was abandoned in favour of a larger, more capable version, the S.E. 2010 Armagnac. 
The Armagnac was a cantilever mid-wing monoplane with retractable tricycle landing gear designed for [[transatlantic flight|transatlantic]] service. A number of versions were planned from a 60-passenger "sleeping berth" version to 84-passenger, 108-passenger and 160-passenger versions.<ref name= "Stroud p. 61">[[#refStroud1993|Stroud 1993]], p. 61.</ref><ref name="Green and Pollinger p. 175"/>
 
After delays to the planning because of [[World War II|wartime]] conditions, work proceeded quickly at Toulouse, Marseilles and Paris, where various components were being built and tested. The Armagnac was designed from the outset in a [[Cook-Craigie plan|Cook-Craigie]] production line prior to the first prototype which flew on 2 April 1949 with Sud-Est Chief Pilot Pierre Nadot at the controls but was lost on 30 January 1950 while still undergoing tests.<ref name= "Stroud p. 59">[[#refStroud1993|Stroud 1993]], p. 59.</ref> The first production series aircraft F-BAVD flew on 30 December 1950.<ref name="Green and Pollinger p. 175"/> Examples of the S.E.2010 were demonstrated at the 1951 and 1953 Paris ''Grand Palais''.

Although the S.E.2010 was powered by [[Pratt & Whitney R-4360|Pratt & Whitney R-4360-B13 Wasp Major]] engines, the most powerful [[piston engine]] ever placed into production for aircraft use, a concern that the final design was underpowered led to a planned redesign.<ref name= "Stroud p. 59"/> The final (15th) production aircraft was intended to be re-engined with 5,400&nbsp;hp [[Allison T40]] turboprops, but production was curtailed at eight and the more advanced version was never built.<ref name= "Stroud p. 59"/> An Armagnac, S.O. 2060, ended its days as an engine test-bed, alternately fitted with turbojet engines fitted in a nacelle below the fuselage. It was tested with two [[Snecma Atar]] 101 turbojets each engine having a different system of afterburner.<ref name= "Stroud p. 61"/> The [[Snecma Vulcain]] was also tested in a similar manner.<ref name="Green and Pollinger p. 175">[[#refGreenandPollinger1955|Green and Pollinger 1955]], p. 175.</ref>
