2. Axial fan design - Wikipedia

   en.wikipedia.org/wiki/Axial_fan_design

   An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the ...

4. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   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 ...

5. Pratt & Whitney JT8D - Wikipedia

   en.wikipedia.org/wiki/Pratt_&_Whitney_JT8D

   The JT8D is an axial-flow front turbofan engine incorporating a two-spool design. There are two coaxially-mounted independent rotating assemblies: one rotating assembly for the low pressure compressor (LPC) which consists of the first six stages (i.e. six pairs of rotating and stator blades, including the first two stages which are for the bypass turbofan), driven by the second (downstream ...

6. Pratt & Whitney Canada PW500 - Wikipedia

   en.wikipedia.org/wiki/Pratt_&_Whitney_Canada_PW500

   The PW530 has a single stage fan, driven by a 2-stage LP turbine, supercharging a 2A/1CF axial-centrifugal HP compressor, driven by a single stage HP turbine. Although similar in configuration, the PW535 has a booster stage, mounted on the LP shaft behind the fan, to increase overall pressure ratio and core flow.

7. Pratt & Whitney PW4000 - Wikipedia

   en.wikipedia.org/wiki/Pratt_&_Whitney_PW4000

   The Pratt & Whitney PW4000 is a family of dual-spool, axial-flow, high-bypass turbofan aircraft engines produced by Pratt & Whitney as the successor to the JT9D.It was first run in April 1984, was FAA certified in July 1986, and was introduced in June 1987.
