He was an Italian polymath of mystery, mischief and mayhem who also managed to make significant contributions to gear technology and games of chance along the way.
The oil-off (also known as loss-of-lubrication or oil-out) performance evaluation of gears is of significant interest to the Department of Defense and various rotorcraft manufacturers, so that the aircraft can safely land in an accidental loss-of-lubricant situation. However, unlike typical gear failure modes such as pitting or bending fatigue where early detection is possible, gear failure in an oil-off situation is very rapid and likely catastrophic. Failures rapidly result in the loss of torque transmission and the inability to control the aircraft.
Finding capable, dependable machinists is one of the great challenges of modern manufacturing. Most gear manufacturers we talk to would hire more machine
operators - if only they could find them. They lament the fact that their workforce is getting older and grayer, and they don't know what to do.
