As air travel is set to increase significantly in the next 20 years, jet engine noise reduction is becoming an area of focus for the aviation industry. Ducted fan noise is becoming a dominant source of jet engine noise for most flight phases. For conventional turbofan architectures, this can be linked to the continuous increase in bypass ratio (hence fan diameters) and the reduction of nacelle inlet length. For electrified powertrain concepts that rely on fans to produce thrust, such as urban air mobility applications, reducing noise emissions is critical for certification and market success, due to the lower flight altitude and flight routes within urban environments.

Turbofan engine noise mitigation

For numerous applications, mitigation of ducted fan noise emission is a major design challenge, particularly in the context of aircraft propulsion, where certification standards have become more stringent over the last decades to support sustainable mobility solutions that protect the environment.

With current design practices, many physical tests on stationary rigs or during fly-over tests are still required to fulfill all design requirements. Numerical methods have the potential to improve that process by reducing the time and cost to assess design variants. To be effectively deployed within the industry, these methods must be able to capture the major physical phenomena while offering a competitive computational cost.

With this objective in mind, this webinar introduces the capabilities of Simcenter to simulate ducted fan noise emission. An application example will illustrate how technologies from the Simcenter portfolio can be combined to support jet engine noise reduction.
