Methods of Controlling Distortion of Inlet Airflow During Static Acoustical Tests of Turbofan Engines and Fan Rigs(STABILIZED Dec 2020)
This Aerospace Information Report provides guidelines for hardware design. Guidelines on such items as engine types, test arrangements, and test purposes that would benefit from the use of an inflow control device during static noise testing are outside the scope of this report.
This AIR is in need of an update, but recent engineering guidance is lacking. There is some work in this area being done by industry, and if at some time in the future an industry need arises, SAE A-21 can create a WIP to update. In the meantime, the document should be stabilized.
