American Jet Industries Hustler

Unveiled at American Jet Industries plant in Van Nuys, California, in October, 1975, the seven-place Hustler 400 turboprop/ turbojet has been modified since announcement was made. A major change was the redesign of the tail to a "T" tail configuration, and other changes include an increase of 52 inches in the wing span and installation of double-slotted Fowler flaps on the supercritical wing. Sixteen inches have also been added to the fuselage.


An 850 shp United Aircraft of Canada turboprop PT6A-41 in the nose provides power for the Hustler while the Teledyne turbojet engine will be used for standby' power in the event of an engine failure. According to American Jet's data the standby engine will enable the aircraft to maintain an airspeed of 170 mph at 13,500 feet with the nose turboprop engine feathered. A top speed of 380 mph for the Hustler is predicted with a maximum range of 2970 miles.


Three prototypes were under construction at the American Jet California facility; two were to be used for flight testing and the third for ground structural testing. The Hustler faces some serious hurdles; for instance, no certificated jet engine of the size required by the design existed. Only various engines used for APUs, missiles or drones. If, on the other hand, a "single-engine" classification were sought, the jet engine being viewed merely as a JATO unit, then the Hustler would face the challenge of making the FAA's 70-mph land-ing speed requirement with a wing loading of at least 36 pounds per square foot.


The Hustler was powered by a Pratt & Whitney PT6A-41 turboprop in the nose and a standby turbojet in the tail and made its first flight on January 12, 1978.
Gulfstream American decided to replace the 850-shaft-horsepower Pratt & Whitney PT6 turboprop engine in the nose of the Hustler with a 900-shp Garrett TPE331. The Pratt & Whitney JT15D remains Gulfstream’s choice for the Hustler's rear-mounted turbofan. Maximum takeoff weight was been increased to 10,000 from 9,500.


Flight testing of the Gulfstream American Hustler 500 began late in January 1981 at Van Nuys, California, and continued at Mojave. This second Hustler prototype was powered by a 900 shp Garrett AiResearch TPE 331-10-501 turboprop in the nose and a 2,200 lb st (1000 kgp) Pratt & Whitney JT15D-1 turbofan in the tail.
