Functional Jet Engine Parts Built Using AM (GE Aerospace)
Qualification of Additive Manufacturing (AM) machines and materials is a major barrier for the broad adoption of AM. Generating the requisite data and models requires large investments of resources and time from small/ medium businesses to produce a body of statistically significant data. This usually requires generating coupons under a controlled process, testing the coupons, and analyzing the resulting data. Moreover, part vendors are required to supply substantially different data to each Original Equipment Manufacturer (OEM), even when using the same manufacturing process. The OEM supplier qualification process, the requirements that are often held as proprietary information, could benefit from common requirements across application sectors such as Engine, Structural, and Mechanical Subsystems.
The objective of this project is to document the qualification requirements of in-service metal AM parts accepted by design authorities of three engine OEMs as part of their individual qualification/certification efforts.
Advanced Science and Technology Research Organization of America (ASTRO America), the principal investigator (PI) for this project, will:
