Torque measurement
Randy G: 'The one that is used most often is the torque gauge. It measures oil pressure at a set of gears usually in the main rotor transmission . . . '
Randy, we should all be careful when suggesting anything like 'this is the way it is done'. For example, the Super-Puma series of helicopters uses a 'hall-effect' probe to measure torque (Nick Lappos may explain, if you ask) which has nothing at all to do with oil pressure and everything to do with twisting moments.
Anyone wonder why Eurocopter don't have a Nick Lappos equivalent?
Anyone wonder about the future of ECF?
Anyone wonder if the two questions are related?
