Mikoyan MiG SVB
The Mikoyan MiG SVB was a 1990s Russian project to develop a turboprop-powered regional airliner and cargo transport for hot and high environments, including operations at night and in all weather. The SVB was expected to have considerably lower operating costs than similar aircraft already in service, such as the Antonov An-32, largely due to the type's newer and lower-power Klimov TV7-117S engines.
"SVB" stood for Samolet Vysotnogo Bazirovaniya — "Aircraft for high-altitude bases" in Russian, and the project was known internally at MiG as article 801. Political and economic instability around the dissolution of the Soviet Union ended the project in 1994.
Design
The SVB design was conventional for aircraft of its type: a shoulder-wing cantilever monoplane with a conventional tail. It was to have retractable tricycle undercarriage, with the main units retracting into fairings on the sides of the fuselage, in addition to flotation devices. Power was to be provided by two turboprop engines mounted on the wings, driving tractor propellers. The wings were to be equipped with high-lift devices. One unusual feature of the design was that the fuselage maintained a constant, rectangular cross-section from aft of the flight deck all the way to the rear of the aircraft.Two basic passenger configurations were proposed for the regional airliner: a standard 40-seat version with eight rows of five seats, and a 50-seat high-density version with ten rows of five seats at a decreased pitch. In both cases, a single aisle was to be provided, offset to starboard.
In cargo configuration, the SVB was to be equipped with a loading ramp in its rear fuselage and have an electric hoist fitted on tracks on the cabin ceiling. The interior was to be fully pressurised.
