Comparison of several inflow control devices for flight simulation of fan tone noise using a JT15D-1 engine
TL;DR: In this article, the authors describe the tests of four devices intended to reduce inflow disturbances and turbulences using a JT15D-1 turbofan engine, and the tests were made to simulate the in-flight fan tone noise; the inflow control devices consisted of honeycomb/screen structures mounted over the engine inlet.
Proceedings ArticleDOI
Full-scale upper-surface-blown flap noise
TL;DR: In this paper, a TF 34 engine was used to investigate the noise of several powered lift configurations involving upper surface blown (USB) flaps, and the results of velocity surveys at both the nozzle exit and the flap trailing edge were used for correlation of the noise data.
