Contribution to HIKARI

NLR will evaluate the noise performance of a pre-cooled turbojet engine for high-speed transport for the landing and take-Off cycle. Based on engine- and jet noise models, a noise analysis will be carried for the pre-cooled turbojet engine at certification points (Annex 16). A comparison will be made with maximum allowable noise levels as provided by ICAO Annex 16 and where possible, certification noise levels of relevant aircraft that are available in open literature.
