Gulfstream Peregrine


In July 1979 Gulfstream American (later Gulfstream Aerospace) revealed its plans to develop the Peregrine as a military trainer on the basis of its Hustler 500, an unusual executive jet powered by a nose-mounted turboprop and a tail-mounted turbofan. The trainer was based closely on the Hustler 500 without accommodation for passengers in the fuselage, without tip tanks, and with the forward fuselage revised to eliminate the turboprop and provide side-by-side seating for the pupil and instructor. The structure was of the conventional all-metal type with a semi-monocoque fuselage and cantilever low-set wings. As first flown in May 1981, the Peregrine had drag-reducing Whitcomb winglets on the upper surfaces of the wing tips, though these were later moved to the under surfaces. The engine was located in the rear of the fuselage, and was aspirated via a dorsal inlet whose aft contours formed the structural basis for the swept tail surfaces. The sole prototype crashed in November 1983, and further development was abandoned. A possible derivative had tandem seating and two 1,500-lb (680-kg) thrust Williams WR44 turbofans, and the details below apply to the planned basic production version.
