Considera8ons for <strong>ANOPP2</strong><br />
• Revisit the paradigm <strong>of</strong> a component-‐based approach<br />
– Can one adequately model the inlet noise from an engine by considering the fan<br />
and compressor contribu&ons separately?<br />
– Can one adequately model the jet noise without considering the influence <strong>of</strong> the<br />
pylon?<br />
• Can installa8on effects (PAA, AIA) be accounted for in some approximate<br />
but rigorous manner?<br />
– Must they be an integral part <strong>of</strong> the source descrip&on themselves?<br />
• Non-‐compact sources: distributed sources such as jet noise<br />
• Requirement to predict acous8c near-‐field<br />
– ScaCering <strong>of</strong> engine sources due to airframe<br />
• What do we mean by mul8-‐fidelity and how do we implement it?<br />
• Can a common mathema8cal framework be defined for <strong>ANOPP2</strong>?<br />
– e.g. ANOPP : compact uncorrelated source framework<br />
