GARDN II Projects (2014-2019)
Noise Reduction for Next-Generation Regional Turboprop
This project is aimed at leveraging new technologies, maturing concepts and design guidelines for noise reduction of a large regional turboprop aircraft in order to meet and exceed ICAO new Chapter14 aircraft noise requirements and very stringent airport local noise limits.
More specifically, the project plan is set to mature a range of installed engine-noise-reduction concepts, and it includes multiple elements: Noise Reduction of an Integrated Powerplant, Parametric Studies of Low Noise Propeller Design Concepts, Advance Duct & Liner Technology and compressors, and Demonstration of noise Reduction Concepts and Technologies with Rig and Engine Testing.
The technology advancement to TRL6 of noise-reduction concepts is a must for the development of a new large environmentally friendly turboprop aircraft.
