Oil-Out Endurance Under the Lens

January 1, 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 can't last 30 minutes under such conditions before they catastrophically fail, and the whole system usually follows shortly after. That doesn't leave pilots with a whole lot of time to find a suitable location to land in the case of an oil-out emergency.

Problem Solving for the Gear Industry

January 1, 2017

If you've got a gear performance problem, the Gear Research Institute (GRI) is here to help you. Since inception in 1982, GRI has been a primarily industry sponsored, experimentation driven research facility. Whether establishing the fatigue life of gears or evaluating the impact of manufacturing processes on the performance of gears, GRI has pioneered methods and procedures for characterizing such properties that are accepted by the aerospace, vehicle and other industry sectors.

The essence of designing gears is often by necessity risk-averse, given that many of them are used in applications where loss of life is a distinct possibility. The Gear Research Institute (GRI) at The Pennsylvania State University conducts risk reduction testing with the same goal in mind - whether it be gears in fighter jets, Ferris wheels, tanks, or countless other gear-reliant vehicles and machinery.

An Invitation To Be A Champion

November 1, 1988

Recent history has taught us that global competition has become tougher and is a major concern of American gear manufacturers from abroad have invaded American markets with products designed in an environment where management of technology has been practiced effectively. If American companies intend to compete in the changing world market, they must acquire the technologies that will allow them to do so.

Balance is Critical - Monitoring Essential

November 1, 1986

These are changing times for industry. Trauma and uncertainty are always a part of change, and change is not always for the better. Change is usually forced, most frequently by competition. Our competitive free enterprise system should be able to respond to competition because that's its basis. These are critical years. If we do not respond effectively to change and competition, it could be disasterous.
