Description / Abstract:
The effectiveness of Engine Life Usage Monitoring and Parts
Management systems is largely determined by the ai rcraft-specific
requirements. This document addresses the following areas:
a. Safety
b. Life-limiting criteria
c. Life usage algorithm development
d. Data acquisition and management
e. Parts life tracking
f. Design feedback
g. Cost effectiveness
It primarily examines the requirements and techniques currently
in use, and considers the potential impact of new technology to the
following areas:
a. Parts classification and control requirements
b. Failure causes of life-limited parts
c. Engine life prediction and usage measurement techniques
d. Method validation
e. Parts life usage data management
f. Lessons learned
g. Life usage tracking benefits
Purpose:
SAE ARP1587 provides general guidance on the design
considerations and objectives of monitoring systems for aircraft
gas turbine engines. A major function of these Engine Monitoring
Systems is to monitor the usage of life-limited parts in order to
maximize available life and to enhance aircraft safety.
The purpose of this document is to review the current approaches
to Engine Life Usage Monitoring and Parts Management. The document
also serves to provide a summary of the many varied requirements of
aircraft turbine engine life usage monitoring and parts management
(see Appendices A and B) and a description of the means by which
these requirements can be achieved more effectively through the use
of engine monitoring systems.
