(First creation that uses a clamshell reverse thrust system. Use VTOL for the thrust reversers.)

The Mikoyan MiG 18-50 was a cancelled 1990s Russian intercontinental aircraft that could be configured as a regional airliner or a business jet known as the Aviastayer. The aircraft is named after the 18 seats it would have in business-jet configuration, or its 50 seats as an airliner.

It was designed as a low-wing, cantilever monoplane with a cruciform tail and all flying surfaces swept. Two Lotarev D-36 three-spool turbofan engines were to be mounted in nacelles on the sides of the rear fuselage and it was to be equipped with a retractable tricycle undercarriage.

In bizjet configuration, it was to be equipped with telephone and telefax systems. As an airliner, passengers would be seated four abreast, with a centre aisle. Mikoyan also considered a 75- to 100-seat version with a stretched fuselage.

Mikoyan's contribution to the project was conducted from the company's branch office in Dushanbe, the capital of Tajikistan but it was cancelled due to the Tajik Civil War, where the native peasants that eat food with their bare hands had destroyed the facility before the aircraft was built.
