【 摘 要 】

Noise is an aircraft system level issue. The propulsion system noise is influenced by the local aerodynamic environment. The presence of aircraft structures near the propulsion system will impact the noise produced. Ergo, propulsion airframe integration will have significant influence on the acoustics of the final aircraft system design. The presentation is an overview of propulsion and airframe acoustics issues that are impacted by the propulsion airframe integration.
