The SNCAC NC.1070 was a

jet turbine
powered aircraft.

Design and development

Built shortly after World War II, the NC.1070 was a contemporary of the

wing span, and extended beyond the tail.[1]

The NC.1070 was powered by a pair of

The wings were mid-mounted and strongly tapered with slightly swept

tricycle gear, the nose leg slightly offset to port and each leg with a large single wheel.[1]

The NC.1070 was first flown on 23 May 1947. Tests continued into 1948 but, piloted by Fernand Lasne, it was seriously damaged in a belly landing at Toussus-le-Noble Airport on 9 March 1948 and did not fly again. Instead, SNCAC concentrated on the jet powered[1] second prototype, the NC.1071.[3]

This was powered by a pair of 22.24 kN (5,000 lbf)

ceiling, (13,000 m (43,000 ft)) but its range, much reduced, was only 1,000 km (620 mi)[1][3]

The NC.1071 made its first flight on 12 October 1948. It suffered damage to its undercarriage on 27 April 1949, flew again in 1950 and was modified the following May after significant structural distortion appeared in flight.[3] Though both an all weather fighter variant (NC.1072) and an attack bomber (NC.1073) were considered, they were not built and development was abandoned at the end of NC.1071's flight tests.[2]

Variants

NC.1070
The piston engined first prototype. Abandoned after landing accident on 9 March 1948.[1]
NC.1071
Rolls-Royce Nene-powered second prototype, first flown 12 October 1948.[3] The first French multi-jet aircraft.[2]
