The scope of these standards will relate to single-axis moment scales only. Topics covered include dimensional characteristics of single-axis moment scale interfaces, general tooling requirements, scale and tooling accuracy, and display instrument accuracy requirements. Additionally, general guidelines for qualification of equipment and tooling are included, as are general requirements for single-axis blade distribution software.
This document establishes process parameters for gas turbine rotor balancing. Adherence to the recommendations made herein will facilitate attainment of the usually high degree of accuracy and precision required for jet engine rotor balance.
The primary goal of this new Aerospace Information Report is to provide guidelines to conduct effective Gage R&R studies for balancing tasks. This new Aerospace information report will inform process planners and machine operators how to properly conduct a Gage R&R study and interpret results. The contents of the report are: introduction, step by step guidelines to conduct Gage R&R study, data analysis options, and result interpretation.
The goal of this new Aerospace Information Report is to supplement the content of AS6327™ and provide a reference document for the new Aerospace Standard. This new Aerospace Information Report will serve as a practical resource that offers guidance to the machine operator and Process Engineer for isolating the source(s) of non-repeatability in measured unbalance data. The content will include: • Machine Capability to achieve the specified unbalance tolerances and repeat within those tolerances • Tooling Capability to repeat within the specified unbalance tolerances • Rotor characteristics that may preclude repeating within the required unbalance tolerances.
This document establishes general design criteria, tolerances, and limits of application for tooling, fixtures and accessories for mounting and driving gas turbine engine rotors on horizontal and vertical balancing machines. For your own safety, while using balancing tooling, regard the safety instructions of the individual supplier.
Provide a fundamental understanding of reason for completing a bode plot on the balance machine. Discuss potential causes of a resonance within the balance process. Discuss the basis for the WN^2 requirement and how it pertains to the bode plot. Provide guidelines for the usage and interpretation of the bode plot.
Provide guidance on how balance machine vector data is captured and reported. Provide an understanding of how to transform balance machine vector data to alternate locations. Provide guidance on how vector imbalances may be used to evaluate and diagnose balance process performance.
This document specifies those requirements of balancing equipment which make it suitable for the subject class of work. It will specify: (a) Sensitivity, (b) Accuracy of indications of amount and angle of unbalance, (c) Ability to separate the Dynamic Unbalance into two planes and to separate Static and Couple Unbalance, (d) Machine capacity relating to weight and physical dimensions of the rotors which can be balanced, (e) Balancing speed of rotation, (f) Standard balancing machine drive adapter flange dimensions, (g) Standard shroud mounting pads, (h) Power requirements.
