Hydraulic and Direct Drive Fans


Mechanical Drive Fans
Mechanical Drive Fans

AMETEK Airscrew has developed a range of mechanically driven fans for cooling systems in aerospace applications. Both mixed flow and axial fan types can be offered, providing extremely high performance together with robustness and low weight. A number of drive options are supported: these include belt drive from an engine or gearbox; shaft drive, via a splined quill shaft; or direct drive via a high precision, spur gear. AMETEK Airscrew can also offer a complete system including a fan, heat exchanger and all associated ductwork. We are experienced in working with the airframer to fully integrate the system into the aircraft, thereby ensuring optimum performance.

AMETEK Airscrew’s design capability encompasses the following elements:

  • Aerothermal design including   modelling of the system geometry and aerodynamic losses
  • Calculation of the cooling element core mass flow and pressure drop to determine heat dissipation
  • Optimization of the system for minimum losses/maximum fan efficiency
  • Detailed design of the impeller and cooler packaging
  • Detailed design of the casing, mounting and airframe interfaces to ensure mechanical integrity in high vibration applications
AMETEK Airscrew direct Drive Fans are designed for cooling of engine or gearbox oil. We currently produce a number of systems for a variety of rotary wing apllications.

Hydraulic Drive Fans

<p>Designed for high performance with low power consumption, the Airscrew Hydraulically driven range of fans have non-stall performance and non-overloading power characteristic, together with low noise emission levels. The backward-inclined impeller blades are particularly suited for use in dusty conditions in that the blades remain clean, thus avoiding loss of efficiency. </p>

<p>Depending on the complexity of the installation, mounting methods can be adapted to suit individual requirements of compact, robust construction and manufactured to meet the requirements of Government defense equipment specifications. These fans are especially suitable for military vehicle engine-cooling applications.</p>

<p>With applications including Main Battle Tanks, Armored Personnel Carriers, Infantry Fighting Vehicles, light tanks, all terrain vehicles, down to 4 x 4 Scout vehicles, there are many thousand of these fans successfully installed either as stand alone units, or as part of Engine Cooling Systems. </p>
