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 کاملA Simulator for Modeling Aircraft Surface Operations at Airports
Rapid prototyping of integrated taxiway and runway schedulers at airports has become highly desirable for Safe and Efficient Surface Operations (SESO) to support the Next Generation Air Transportation System (NextGen). Finding optimal solutions for taxiway and runway scheduling are generally computationally difficult and therefore it is essential to develop fast algorithms that can produce high...
متن کاملCharacterizing acoustic shocks in high-performance jet aircraft flyover noise.
Acoustic shocks have been previously documented in high-amplitude jet noise, including both the near and far fields of military jet aircraft. However, previous investigations into the nature and formation of shocks have historically concentrated on stationary, ground run-up measurements, and previous attempts to connect full-scale ground run-up and flyover measurements have omitted the effect o...
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 کاملSimilarity spectra analysis of high-performance jet aircraft noise.
Noise measured in the vicinity of an F-22A Raptor has been compared to similarity spectra found previously to represent mixing noise from large-scale and fine-scale turbulent structures in laboratory-scale jet plumes. Comparisons have been made for three engine conditions using ground-based sideline microphones, which covered a large angular aperture. Even though the nozzle geometry is complex ...
