Abstract

In this paper a review on noise sources of a military flying vehicle is carried out. The typical operational speed of a fighter is always near or above Mach one, and turbulent boundary layer and its interaction with airframe as a sound generation mechanism become more significant while the stream velocity is increased. There are many other sound generation mechanisms at low subsonic speeds in propeller airplanes and most civilian jet aircrafts, but these are not discussed here. The most common flow-induced sound generation mechanisms are considered and the dependency between stream velocity and generated sound power is illustrated. An extensive review to literature of aviation noise is done.
