The Response of a Rotor to Transient Inflows: Analytical Study
Abstract
This proposal describes a three year program of work that is designed to improvebroadband inflow turbulence modeling for rotors operating near complex boundaries bydeveloping methods that directly link upstream flow characteristics to the turbulence atthe inflo"w plane, the unsteady loading of the rotor and the far field sound radiation. Thework will be carried out by Dr. Stewart Glegg at F"lorida Atlantic University incollaboration with parallel programs being proposed by Dr. William Devenport and Dr.Nathan Alexander from Virginia Tech and Dr. Meng Wang from the University of NotreDame. The proposed work will focus on the prediction of the turbulence ingestion noisefrom rotors in complex environments by modeling the experimental measurements thatare being carried out at Virginia Tech. The program at Notre Dame will undertakenumerical LES calculations of the Virginia Tech experiment. This study builds on theachievements of previous current grants (Grant number N00014-10-1-0910 and N00014-14-1-0293) and extends the results to more complex environments.
