Information About

Mcdonnell Douglas Md-94x




The McDonnell Douglas MD-94X was a planned Propfan -powered Airliner , intended to begin production in 1994 . The aircraft was to seat between 160 and 180 passengers in an unknown seating configuration. An all-new design, it was begun in the late 1980s to compete with the similar Boeing 7J7 . Configuration was similar to the MD-80, but advanced technologies such as canard noseplanes, laminar and turbulent boundary layer control, side-stick flight control (via fiber optics), and aluminum-lithium alloy construction were under consideration.

Airline interest in the brand-new propfan technology was weak despite claims of up to a 60% reduction in fuel use, and both aircraft were cancelled.

Under development at the same time were two propfan variants of the MD-80 . The MD-91X would have seated 100-110 and entered service in 1991 , and the '''MD-92X''' was to seat 150 and enter service in 1992 .

Existing DC-9 s and MD-80s would also have been eligible for an upgrade to the new propfan powerplants.
