Abstract: A system and method of non-intrusive anemometry. The system comprises an acoustic transmitter disposed at a boundary of fluid flow and first and second acoustic receivers adapted to receive transmissions from the acoustic transmitter. A processor is coupled to the acoustic receivers to determine the time of arrival of the transmission at the acoustic receivers. The acoustic transmitter and acoustic receivers are arranged such that the acoustic transmitter is upstream from the first acoustic receiver which is in turn upstream from the second acoustic transmitter.

Abstract: An exhaust system for a gas turbine engine is provided. The exhaust system includes an exhaust diffuser having a diffuser axis. The exhaust diffuser includes an outer diffuser wall. The exhaust diffuser also includes an inner diffuser wall. The exhaust diffuser further includes a diffuser inlet formed by the first and second upstream ends of the outer diffuser wall and the inner diffuser wall. The exhaust diffuser includes a diffuser exit. The exhaust system also includes an exhaust collector coupled with the exhaust diffuser and adapted to collect and redirect exhaust gases in a radial direction. The exhaust collector includes a circumferential wall. The exhaust collector also includes a forward wall. The exhaust collector further includes an aft wall, wherein the aft wall is angled with respect to the diffuser axis. The exhaust collector includes a splitter disposed between the forward wall and the aft wall of the exhaust collector.
