Noise of High-Performance Aircraft at Afterburner
Abstract
The main objective of this project is to obtain a fundamental understanding of the physics of noise generation of a high performance aircraft operating at afterburner condition. The new noise components are indirect combustion noise produced by the passage of entropy waves through the nozzle of the jet. To obtain a good understanding of the noise generation processes through numerical simulation, it is imperative that a way be found to reproduce such a random wave field with prescribed statistical averaged properties computationally. Here the development of a one-dimensional computational model capable of generating a broadband entropy wave field with a prescribed intensity and frequency spectrum is reported.
