Load Spectrum Measuring Equipment. Part 1. Details of Mk 1 System Presently Used to Acquire Data in Wessex Mk 31B Helicopters.

摘要

Measuring equipment has been developed which uses a set of electromechanical counters to indicate the integrated time inseconds for which torque loading on a transmission component falls within each of a number of bands. Separation of the torque level into bands is made possible using a single transducer, an amplifier with zero and gain adjustments for setting the extremes of the torque range of interest, an analogue to digital converter and decoder to separate the torque range into bands and counters to totalize contributions in each band.
