What is it about?
Jet engine noise reduction remains a significant concern in the aviation industry. Tthe proximity between the wing and the engine in underwing installations tends to aggravate the noise generation due to jet-surface interaction (JSI). In this study, we employ mathematical models to predict the noise generated by a geometrically modified nozzle mounted beneath an airfoil and its effectiveness in reducing noise levels compared to a conventional nozzle.

Why is it important?
The noise generated by aircraft is known to have deleterious effects on human health, including sleep disturbance and cardiovascular disease. Since it became a public health issue in the late 1960s, legislative controls have become systematically stricter over the years, demanding the development of quieter aircraft.
