Characteristics of the wind tunnel are as follows: 1) Test section size 6 x 6 ft. by 72 ft. long. 2) Turbulence intensity (minimum) -- 0.001 to 0.005. 3) Mean velocity range -- 1 - 100 ft. per sec. 4) Mean velocity variation across test section -- + 1 percent of center velocity. 5) Mean velocity steadiness -- + 1 percent of velocity setting. 6) Stream wise pressure gradient -- adjustable to zero. Completed portions of the wind tunnel are illustrated by appropriate photographs.reportsengCopyright and other restrictions may apply. User is responsible for compliance with all applicable laws.
