Hybrid Gear Preliminary Results-Application of Composites to Dynamic Mechanical Components [PDF]
, 2012 Composite spur gears were fabricated and then tested at NASA Glenn Research Center. The composite material served as the web of the gear between the gear teeth and a metallic hub for mounting to the torque-applying shaft.

Effect of operating conditions on gearbox noise [PDF]
, 1992 Low contact ratio spur gears were tested in the NASA gear noise rig to study the noise radiated from the top of the gearbox. The measured sound power from the gearbox top was obtained from a near field acoustic intensity scan taken at 63 nodes just above

Effect of extended tooth contact on the modeling of spur gear transmissions [PDF]
In some gear dynamic models, the effect of tooth flexibility is ignored when the model determines which pairs of teeth are in contact. Deflection of loaded teeth is not introduced until the equations of motion are solved.
