The article "CFD Technology for Rotorcraft Gearbox Windage Aerodynamics Simulation" appeared in the August 2009 issue of Gear Technology.

Summary
A computational fluid dynamics (CFD) method is adapted, validated and applied to spinning gear systems with emphasis on predicting windage losses. Several spur gears and a disc are studied. The CFD simulations return good agreement with measured windage power loss.
