The all-composite Triumph, an 8500-lb, 41,000-ft
capable, pressurized 8-seat corporate aircraft, was designed
around the then-unflown Williams FJ-44 turbofan engine.
In 1988, Scaled performed the first flight of the Triumph,
which was also the first flight tests of the FJ-44. Our
subsequent test program, which consisted of over 100 hours
of flight tests, confirmed the performance and operating
characteristics of both the engines and the airplane. The
Triumph was tested to over 41,000 ft, at speeds up to .69
Mach. Pressurization systems were developed, installed,
and tested, basic handling qualities and performance tests
were conducted, and a significant body of engine tests were
performed.
