Description / Abstract:
This document specifies those requirements and procedures for
periodic for periodic tests to insure maintenance of balance
machine capabilities for balancing jet engine components.
It will specify:
(a) Requirements for tests
(b) Calibration tests
(c) Residual unbalance and accurate angle and amount indication
tests
(d) Plane separation test
(e) End-drive system unbalanced disturbance test
Reference Standard: See ARP 587A, Balancing Machines for
Jet Engine Components - Compressors and Turbines - Rotating Type -
For measuring Unbalance in More than One Transverse Plane.
PURPOSE
To define a standard method for the Periodic Surveillance of
Horizontal Dynamic Balancing Machines.
