- Scaled Composites ATTT
The Scaled Composites Model 133-4.62 ATTT, or Advanced Technology Tactical Transport was a technology demonstration project built by
Burt Rutan 'sScaled Composites in1986 under contract toDARPA . The aircraft built was a 62% scaled version of a proposedSTOL transport. The project's goal was to demonstrate novel applications of technology to enable new transport aircraft to operate out of shorter airfields. The core of this technology was a novel utilization of eightFowler flap s, which proved quite successful.The ATTT was essentially two different aircraft during the life of the program. Initially, the aircraft was built with a standard-configuration cruciform tail. In this mode, it flew 51 test flights which evaluated performance and handling qualities. After deficiencies were identified by the flight test program, the tail was redesigned, and the aircraft was rebuilt with a twin-boom type tail.
The ATTT was powered by a pair of
Pratt & Whitney Canada PT6A turboprop engines.The aircraft has been de-registered and is currently in storage at the Air Force Flight Test Center Museum at
Edwards Air Force Base .Trivia
Although the aircraft's official name was the Advanced Technology Tactical Transport, around the Scaled factory (which has a renown sense of humor) the working name for the project was Special-Mission Utility Transport, or SMUT.
