  2. Fan disk - Wikipedia

    en.wikipedia.org/wiki/Fan_disk

    Diagram of a fan disk Fan disk assembly diagram, showing one blade and attachment hardware Cross section of fan disk Failed fan disk recovered from the center engine of UAL 232. A fan disk is the central hub of a fan in a turbofan engine. Fan blades are attached to the fan disk, which is rotated by a shaft driven by a gas turbine. [1]

  3. Fan (machine) - Wikipedia

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

    A household electric fan A large cylindrical fan. A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner.

    A proposed variant targeted toward the Regioplane consortium's 80-130-seat Regioliner RL 92/RL 122 (the successor to the MPC 75), [18] with a 55 in diameter (140 cm) fan, [17] 14,000–20,000 lbf (62–89 kN; 6,400–9,100 kgf) of thrust, a new eight-stage compressor, dual-bank combustor, and a four-stage low pressure turbine [19]

  5. Centrifugal fan - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_fan

    A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).

  6. Ducted fan - Wikipedia

    en.wikipedia.org/wiki/Ducted_fan

    A ducted fan may be powered by any kind of motor capable of turning the fan. Examples include piston, rotary (Wankel), and turboshaft combustion engines, as well as electric motors. The fan may be mounted directly on the powerplant output shaft, or driven remotely via an extended drive shaft and gearing.

  7. Turbofan - Wikipedia

    en.wikipedia.org/wiki/Turbofan

    A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion.The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage.

  8. Fan clutch - Wikipedia

    en.wikipedia.org/wiki/Fan_clutch

    Engine fan with viscous drive. A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.

  9. 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 ...
