- Jet noise problem has been around since the first jet aircraft. Reducing jet noise to minimise the impact on the environment is difficult because it involves controlling the turbulence. Chevrons provide an opportunity to achieve this effect. This is the first paper which discusses how jet noise reduction by applying chevrons can be modelled at the sound source through combining a first principle LES solution and the industry-standard RANS method. The developed approach led to an AARC project supported by leading aerospace industries and NASA Glenn in 2018-2019, which work led to H2020 DJINN project (2020-2023) supported by European Commission.
