The McDonnell Douglas MD-94X was a planned propfan aircraft. Planning began in January 1986, and the aircraft was to go into production eight years later. The MD-94x was designed as a short-haul aircraft for 160 to 180 passengers, which should compete with the Boeing 7J7, which is currently being planned.
The construction of the aircraft by McDonnell was dependent on the oil price. This would at least at 1.40 USD per gallon must be.
The MD-94X configuration was similar to the MD-80 , except that advanced technologies such as canards , side-stick flight control controlled by fiber optics , and aluminum-lithium alloy construction should be used. Despite the brand new Propfan technology and a fuel consumption reduction of up to 60%, the interest of the airlines was so low that the project was discontinued in the planning phase.
At the same time, two Propfan variants of the MD-80 were developed. The successor models MD-91X (100 to 110 seats) and MD-92X (150 seats) should be put into service in 1991 and 1992 respectively. The existing models DC-9 and MD-80 could have been upgraded to the new Profan engines.
