Dr. Robert F. Handschuh

has over 30 years of experience with NASA and Department of Defense rotorcraft drive system analysis and experimental methods. He serves as the Chief for the Rotating and Drive Systems Branch at NASA Glenn Research Center in Cleveland. He has recently led research at Glenn in high-speed gearing, including windage, loss-of-lubrication technology, and hybrid gearing. Handschuh is credited with successfully developing many experimental research test facilities at Glenn and has conducted testing in the following areas: high-temperature, ceramic seal erosion; blade-shroud seal rub; planetary geartrains; spiral bevel gears and face gears; high-speed, helical geartrains; single-tooth-bending fatigue; and high-speed gear windage.
