Aerospatiale SN.600 / SN.601 Corvette
In 1967, Nord Aviation began design studies for a business jet designated the Nord 400. Sud-Aviation was also working on a business jet and in 1968 they joined the projects. The co-operation resulted in the SN-600 of 1969, a low wing business jet with two Larzac engines in rear fuselage pods.
With the 1970 nationalisation of Sud-Aviation, Nord Aviation and the missile manufacturing company, SEREB, the SN-600 became an Aerospatiale project.
The first prototype SN-600, F-WRSN c/ 01, first flew on 16 July 1970 and completed more than 270 flying hours before being lost in a crash in 1971. Two Pratt & Whitney JT15D-1 turbojets powered this aircraft. As a result of the test program the aircraft was redesigned.
The production version of the SN-600, the SN-601, had a stretched fuselage, a taller fin and more powerful Pratt & Whitney JT15D-4 turbofans. The first SN-601, F-WUAS c/n 1, made its maiden flight on 20 December 1972. In September 1974 the Corvette Model SN 601 was approved by the FAA.
The SN-601 Corvette entered production at St.Nazaire in 1973 and deliveries began in September 1974. When production ended in 1977, only 40 were built.
The Corvette has no leading edge flaps or slats. The flight control system has no hy-draulics; it is completely manual, using rods and cables. The engines have no thrust reversers. The basic engineering extends to the wing design, which is derived from a DC-9 -type airfoil. It contains no supercritical technology, yet lateral control is enhanced by wing spoilers, which operate in conjunction with the ailerons, manually.
Crucial systems, such a fuel, electrical trim, flap, speed brake, landing gear and brakes each have adequate backups.
