Windblast Facility Evaluation

Abstract

The windblast test facility at Dayton T. Brown (DTB) was recently reconstructed with several modifications. These modifications were aimed at improving airflow uniformity and increasing the effective blast area. AFRL has routinely used the facility at DTB in its research programs and collaborated with DTB on the evaluation of the facility upgrades. Fifty-two windblast tests were conducted with airspeeds ranging from 375-725 Knots Equivalent Airspeed (KEAS). During these tests the flow at the location of where test articles would be placed was measured. The resulting flow was used to calculate the velocity decay from the windblast nozzle to the test article as well as determine the airflow uniformity across the test article space. It was determined that the airflow was uniform and the system was capable of producing a 700 KEAS blast.
