Description / Abstract:

To provide a standard interface adapter flange on any blade classification instrument capable of meet-ing the sensitivity requirements for the specific class.


To provide a standard Adapter Interface and establish accuracies for different sizes of blade classi-fication instruments to permit moment weighing of two blades which when placed 180 dog apart in a perfect disc, will produce no appreciable static unbalance. The standard Adapter Interface will pro-vide interchangability of adapters between instruments of different manufacturers. The moment weighing scales sizes covered by this document are intended to cover the full range of blades in com-mon use and to detect moment variations from blade to blade when it is positioned at the same radius as in its associated wheel.
