1 An Experimental Investigation of Aerospace-Quality Gears Operating in Loss-of-Lubrication Condition (August 2013)

This work establishes a baseline for aerospace spur gear behavior under oil-off conditions. The collected test results document a different oil-off time, dictated by material used.

2 Oil-Out Endurance Under the Lens (January/February 2017)

Oil-out conditions, or conditions in which an aircraft is operating without any oil in its gearbox or transmission, are devastating for an aircraft's hardware. Even the sturdiest gears usually canít last 30 minutes under such conditions before they catastrophically fail, and the whole system usually follows shortly after. That doesnít leave pilots with a whole lot of time to find a suitable location to land in the case of an oil-out emergency.

3 Test Facility Simulation Results for Aerospace Loss-of-Lubrication of Spur Gears (June 2015)

Prior to receiving airworthiness certification, extensive testing is required during the development of rotary wing aircraft drive systems. Many of these tests are conducted to demonstrate the drive systemís ability to operate at extreme conditions, i.e. ó beyond that called for in the normal to maximum power operating range.
