(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 for a reason I'm not allowed to say and I'm not allowed to mention the site's authority.
