With the standard go-to references in the area increasingly dated and hard to find,Aeroacoustics: Fundamentals and Applications in Aeropropulsion Systems fills the need for a modern take on the fundamental theory and applications relating to prediction and control of all major noise sources in aeropropulsion systems.

Pulling in the latest knowledge and research advances, the book includes detailed consideration of both the physics of aerodynamic noise generation in aero-engines and the relating numerical prediction techniques. It also introduces the new vortex sound interaction models, transfer element method and combustion instability model developed by the book’s author team, helping to disseminate Chinese aerospace findings amongst the global aerospace community.

Focusing on propulsion systems from inlet to exit, including combustion noise, this new resource will aid graduate students, researchers and R&D engineers in solving the aircraft noise problems challenging the industry.

  • Updates the knowledge-base on the sound source generated by aeropropulsion systems, from inlet to exit, including combustion noise
  • Covers new aerodynamic noise control technology aimed at the low-noise design of next generation aero-engines
  • Includes cutting-edge new models and methods developed by an author team led by the Editor-in-Chief of the Chinese Journal of Aeronautics and Astronautics
