Cutaway showing the configuration : 1 fan, 2A+1C HP compressor, 1 HP and 2 LP turbine Type Turbofan: National origin: Canada: Manufacturer Pratt & Whitney Canada: First run November 1993 [1] Major applications: Cessna Citation II Bravo Cessna Citation V Encore Cessna 560XL Embraer Phenom 300 MQ-20 Avenger: Number built: 4,600 (May 2023) [2]
The stall zone for the single axial fan and axial fans operated in parallel are shown in the figure. [4] The Figure shows the Stall Prone Areas differently for One fan and Two fans in parallel. [4] The following can be inferred from the graph : For the Fans operated in parallel, the performance is less when compared to the individual fans.
On the LP spool a three-stage turbine drives a single-stage fan and a four-stage LP compressor. The engine made its first flight August 21, 2000 on a test aircraft flown from Plattsburgh International Airport (KPBG), successfully completing a 1-hour-20-minute flight. [ 1 ]
The list price was $12 million in 2011. [26] At the start of its production in 2016, each GTF was costing PW $10m to build, more than the sale price, but should become less than $2m per engine. [27] MTU provides the first four stages of the high-pressure compressor, the low-pressure turbine and other components.
The two-shaft engine architecture includes a 42.5 in (108 cm) fan with solid wide-chord swept blades, followed by 4 booster stages, all driven by a 4-stage low pressure turbine. The high pressure spool has 4 axial compressor stages and 1 centrifugal stage, driven by a single-stage turbine. [1]

This type of fan is used in a wide variety of applications, ranging from small cooling fans for electronics to the giant fans used in cooling towers. Axial flow fans are applied in air conditioning and industrial process applications. Standard axial flow fans have diameters of 300–400 mm or 1,800–2,000 mm and work under pressures up to 800 ...
The engine featured a single-stage fan, a three-stage low-pressure compressor, and an eleven-stage high-pressure compressor coupled to a two-stage high-pressure turbine and four-stage low-pressure turbine. The JT9D-3, the earliest certified version of the engine, weighed 8,470 lb (3,840 kg) and produced 43,500 lbf (193 kN) thrust. [7]
