Effects of wind on turbofan engines in outdoor static test stands
1983
2nd Flight Testing Conference
unpublished
Preserved Fulltext
Wind can affect measured thrust and can cause turbofan engine speed to fluctuate during outdoor testing. Techniques used at an outdoor test stand at NASA Lewis Research Center to make testing easier and faster and to improve data repeatability include using an inflow control device (ICO) to make fan speed steadier, taking many raw 00 data samples for better averaging, and correcting thrust for wind direction and speed. Data from "' engine tests are presented to show that the techniques improve
