Boeing 7J7 (artist's concept)

The Boeing 7J7 was a short- to medium-range airliner proposed by Boeing in the 1980s, but never built. It would have carried 150 passengers and was touted as the successor to the successful Boeing 727. It was initially planned to enter service in 1992. This was intended as a highly fuel-efficient aircraft employing new technologies, but it was cancelled when the price of oil dropped during the 1980s. Image File history File links 7J7. ...

Technological features

The 7J7 was planned to include advanced technology and electronics such as:

  • fly-by-wire flight control system by Bendix
  • glass cockpit by Honeywell utilizing LCDs
  • advanced integrated avionics suite
  • widespread use of high-strength composites such as carbon-fibre
  • two General Electric GE-36 UDF rear-mounted advanced technology contra-rotating unducted fan engines

The sum of all these features promised better fuel consumption by more than 60% compared to any existing large passenger aircraft technology at the time. "Efficiency" was the key theme. The 7J7 was to have a 2+2+2 seating configuration, giving an unprecedented wide and spacious cabin for its class, with no passenger more than one seat from an aisle.

Foreign partnership

It was also unprecedented in its foreign content with Japan having 25% industrial workshare. Potential airlines customer were concerned about the economics and noise of the unproven propfan engines. Boeing cancelled the 7J7 in 1987 and instead concentrated its resources on further developments of the Boeing 737 and the Boeing 757.

The projects cancellation (as disappointing as it was to the Japanese aviation industry) signalled a new era of cooperation between Boeing and Japanese suppliers.

Competition

Competing with the 7J7 for airline interest was the McDonnell Douglas MD-94X, also powered by propfans, and the (then proposed) Airbus A320. The A320 featured a lot of similar advanced technology and electronics but was powered by conventional turbofan engines. With the cancellation of the 7J7 and the MD-94X offerings, the A320 sold well until Boeing regained parity with the introduction of the next-generation Boeing 737-600 to -900. The next-generation 737s and the 777 incorporate many of the proposed 7J7 improvements. The McDonnell Douglas MD-94X was a planned propfan-powered airliner, intended to begin production in 1994. ...
