Wind Tunnel Simulation and Prototype Studies of Barrier Flow Phenomena

摘要

Design criteria were sought for a wind barrier to be erected along the rain erosion test section of the rocket sled test track at Holloman Air Force Base, New Mexico. Simulated rainfall at the test facility is highly sensitive to cross-wind components, particularly those exceeding one m/s. Research on wind barrier configurations to provide protection for the test track rainfield included both wind tunnel and prototype studies. Results were obtained with a prototype barrier in the open atmosphere and wind tunnel simulation models at scaling ratios of 1:3 and 1:40, giving wind defects for an optimum barrier design of 35% permeability. A barrier design is proposed which would markedly increase the number of days during which the wind-sensitive rain field simulation facility of the test track could be successfully used.
