Engineering Development Program
CurrentRotation 1—Design, 30K GTF FAN & LPC; June 2022-July 2022 • Completed worst-case tolerance stack to validate fan CICR. Rotation 1 CONT.—Design, F135 HPC; July 2022-Jan 2023 • Provided HPC stage 4-6 case nicks, dents, and scratches limits info for QN’s. Rotation 2—Performance, 30K GTFA; Jan 2023-Aug 2023 • Identify when ACC Step Climb Pinch Protection was used in engine test data. • Completed NPSS Open-Loop Analysis for a test engine. • Created an NPSS Pretest Model for a test engine. • Completed a Fan Flutter Audit using the 30K GTFA NPSS status model.• Completed a Trade Study to understand fuel temperature’s impact on takeoff performance. • Used Excel Stacker tool to compare test data from 2 test engines. Rotation 3—Performance, Operability, and MBSE; GatorWorks STP; Aug 2023-Present• Created Aliases for Ubin Parameters in NPSS model. • Compared engine Design Table cycle data to F119 using flight envelope contour plots. • Developed influence coefficients using NPSS model. • Analyzed engine stall recovery. • Developed Verification Requirements in each Test Method in the SRD using Cameo.
