A co-axial subsonic unheated jet with and without a swept lifting wing at free-stream conditions from a recent jet–wing TsAGI experiment is considered. For computational …
The present work is dedicated to the modeling of the low-frequency part of the jet installation noise (JIN) in flight conditions. It is known that the properties of JIN can be predicted based …
Acoustic measurements of turbulent jets in the vicinity of a flat plate, mimicking a neighbouring wing, were compared to results from two wavepacket-based source models …
An experimental study of the azimuthal modes of the sound field generated by a single- stream round jet installed near a flat plate is presented. The investigation is conducted at …

Jet–flap interaction noise for a small-scale swept wing model of a trendsetter plane has been studied experimentally, with a double-stream nozzle installed nearby. The effect of the …
The present work is dedicated to the modelling of the low-frequency part of the jetplate interaction noise in flight conditions. An analytical model used in the work is based on the …
