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:
- Engage with key engine OEMs (GE Aerospace, Honeywell, Pratt & Whitney) to establish a plan and requirements for a common AM qualification template
- Generate a detailed AM qualification template, based on Systems Engineering methodology, that defines requirements sufficient to meet OEM needs for Operational Qualification (OQ) and Installation Qualification (IQ).
- Work with the engine OEMs to identify a specific material/ machine combination to demonstrate the common qualification template with analytic analysis conducted by ASTRO America.
- Review the analytic demonstration results with OEMs, the Government Advisory Team, and NCDMM/America Makes.
