Simulation of Supersonic Military Aircraft Jet Noise
Background: There is a growing need to reduce significantly the noise generated by high-performance, supersonic military aircraft. The noise generated during takeoff and landing on aircraft carriers has direct impact on shipboard health and safety issues. Also, noise complaints are increasing as communities move closer to military bases or when there are changes due to base closures and realign...
متن کاملAircraft type and diagnosed back disorders in U.S. Navy pilots and aircrew.
BACKGROUND Back disorders have long been recognized as a serious problem within the military aviation community and a possible threat to mission accomplishment. The purpose of the present study was to determine the extent to which the type of aircraft flown is associated with diagnosed back problems, and to examine differences in the prevalence of back disorders between pilots and aircrew. ME...
متن کاملSimple - source model of military jet aircraft noise 1 , 2
Described is a method for determining a semi-empirical, equivalent simple-source model that accounts for the aeroacoustic sources in the jet plumes of high-performance military aircraft. The characteristics of the equivalent source are guided by previously reported observations of jet noise, including an asymmetric, partially correlated source distribution and known far-field peak directivity a...
متن کاملAcoustic intensity near a high-powered military jet aircraft.
The spatial variation in vector acoustic intensity has been calculated between 100 and 3000 Hz near a high-performance military aircraft. With one engine of a tethered F-22A Raptor operating at military power, a tetrahedral intensity probe was moved to 27 locations in the geometric near and mid-fields to obtain the frequency-dependent intensity vector field. The angles of the maximum intensity ...
متن کاملSimple-source model of military jet aircraft noise
This paper describes a method for determining a semi-empirical, equivalent simple-source model that accounts for the sound radiation in the vicinity of a high-performance military aircraft. The characteristics of the equivalent source are guided by previously reported observations of jet noise, namely that the strengths of the partially correlated sources are distributed asymmetrically. The par...
