Summary
Pratt & Whitney Canada began development of small gas turbines in the mid-1950s. Experience was first gained with the JT12 turbojet, and P&WC's initial commercial success was with the PT6 turboprop powered Beech King Air, which first flew in 1964.
P&WC began designing the JT15D in 1966 at the request of Cessna, which was developing the new entry-level Citation business jet that first flew in 1969. Simplicity and low cost were key objectives. The JT15D was P&WC's first turbofan engine, and is fairly unique among modern turbofans in that it uses a centrifugal compressor as its main high-pressure system.
The JT15D family produces thrust to 15,100 N (3,400 lb) and has powered several Cessna Citation models, the Aerospatiale Corvette, Mitsubishi Diamond 1/1A, and Beechjet 400A business aircraft.
This artifact was one of two engines that powered the prototype Cessna Citation on its first flight in 1969. It was used mainly during the Citation flight test program.
