Popis:	The objectives of this program were to: validate CFD-based OPD model using wavefront sensor data from wind tunnel experiments; exercise CFD model to assess performance of larger, more realistic configuration with conformal window; and determine wavefront control system requirements. CFD validation consisted of: wind tunnel WFS measurements of phase over scaled turret with conformal window; and comparison with CFD-based model at 1:1 scale including wind tunnel boundaries and inlet flow profile. Large scale analysis entailed assessing performance of larger turret with conformal window, and evaluating wavefront control requirements. The program was successfully completed. Turrets were designed and fabricated; wind tunnel tests were conducted; WFS data was collected; the CFD-based aero model was validated; and large scale analysis and wavefront control requirements were completed.
