THIS IS A CONTINUATION OF N00014-14-1-0141 ADVANCING ANALYTICAL AND LES-BASED PREDICTIONS OF TURBULENCE INGESTION NOISE IN COMPLEX ENVIRONMENTS-AN EXPERIMENTAL STUDY
Abstract
The work below will be performed in collaboration with parallel efforts on the development of theoretical models and prediction methods:1. -Assess the validity of rapid distortion theory predictions of turbulence evolution in known boundary layer shear flow approaching a thrusting rotor.2. - Test the range of validity of blade response and noise generation methodology by documenting the sound field generated by a rotor immersed in a known boundary layer shear flow as a function of rotor yaw (Year 1 and Year 3).3. -Develop the analytical tools and robust instrumentation to advance methods for inferring the statistical and instantaneous structure of turbulence passing through a rotor disk from the rotor acoustic field and on-blade measurements (Years 1 and 2).4. -Establish and document in detail scientifically well posed canonical test cases designed for the development of LES-based broadband rotor noise prediction (Years 1, 2 and 3).
