The National Aerospace Laboratory (NLR) is the main knowledge enterprise for aerospace technology in the Netherlands. NLR carries out commissions for government and corporations, both nationally and internationally, and for civil and military aviation. The overarching objective is to render aviation safer and more sustainable and efficient. In this way, NLR has been making essential contributions to the competitive and innovative capacities of Dutch government and industry for more than 90 years.
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.
