The YC-14 was Boeing 's entry into the USAF 's Advanced Medium STOL Transport (AMST) competition, to replace the C-130 Hercules as the USAF's standard STOL tactical transport. The AMST project introduced a number of innovative features, such as Under-surface Blowing , which used double-slotted Flap s to direct part of the jet exhaust downwards, while the rest of the exhaust passed through and downward over the flaps, introducing the Coandă Effect . The unusual location of the General Electric F103 engines, seen only on a few other aircraft, such as the Antonov An-72 'Coaler' (which flew later), increased lift by passing the exhaust directly over the wing. This also made the aircraft quieter. The YC-14, as well as McDonnell-Douglas ' entry into the competition, the YC-15 , met or exceeded the specifications of the contest. However, the project was cancelled before either product could be chosen. Two YC-14s were built and tested. One is stored at the Aerospace Maintenance and Regeneration Center at Davis-Monthan Air Force Base ; the other is on display at the nearby Pima Air & Space Museum . EXTERNAL LINKS |
