Nord Noratlas: Διαφορά μεταξύ των αναθεωρήσεων

Accordingly, in 1947 [[Direction Technique Industrielle]] organized a design competition for medium-weight cargo aircraft offering great flexibility in use. Société Nationale de Construction Aéronautique du Nord ([[SNCAN]]) answered with the Nord 2500, while their competitors, [[Société Anonyme des Ateliers d'Aviation Louis Breguet|Breguet]] and [[SNCASO]], offered the [[BR-891R Mars]] and [[SO-30C]] respectively. The Nord 2500, with its rear-opening clamshell doors allowing ease of loading, was considered the most promising, and DTI ordered two prototypes on April 27, 1948. The first prototype took to the air on September 10, 1949 powered by two [[Gnome et Rhône]] 14R 1600-hp engines driving 3-bladed variable pitch propellers, but it was found to be too slow for most applications. The second prototype replaced the 14Rs with two [[Media:SNECMA]]-built [[Media:ExampleBristol Hercules]] 738/9 2040-hp engines driving four-bladed propellers, and this model was rechristened the Nord 2501.ogg DTI ordered 3 more preproduction Nord 2501s, which they flight-tested extensively against the similar [[Fairchild]] [[C-82 Packet]]. The N-2501 was found superior, and the first 34 were ordered on July 10, 1951. After an eventual production run of some 425 planes, the last Noratlas was constructed in 1961.
