Achieving Quieter Aircraft Through Simulation

Reducing Aircraft Noise to Comply with Regulations and Meet Certification Standards

The roar of aircraft has become an unwanted part of daily life for the millions of people worldwide who live around airports. Today, quieter aircraft have a competitive edge at airports, with operators potentially getting more slots or lower landing fees.

Engine noise used to be the dominant noise source, but through improvement in that area this is not the case anymore. Today, airframe noise is actually louder in some conditions than the engines. Learn how SIMULIA fluids solutions helped NASA to isolate and reduce the contribution of these external noises.

Aircraft are a significant source of noise pollution for communities near airports. This noise comes from multiple sources, including turbulent airflow around landing gear as well as directly from engines. Engineers are being challenged to reduce aircraft noise to meet increasingly stringent community noise regulations and certification standards. In this whitepaper, learn how SIMULIA aeroacoustic simulation can be used to identify the many sources of noise that are generated by aircraft and mitigate its propagation on the ground.
