Summary

Experimental heat transfer studies were conducted on full scale ribbons of flat circular type parachutes having a geometric porosity of 20.5 percent. A pressurized subsonic wind tunnel served as the flow facility. The average approach flow velocity was 134 feet per second. The measurements were made in the Reynolds number range of one million to ten million, where the Reynolds number is based on the ribbon width of 2.1 inches and on the velocity and temperature of the flow in the slots between the ribbons. The pressure ratio applied to the ribbon was varied from 1.4 to 26.3. Using a transient energy balance, local and average heat transfer data were obtained and compared with available analyses.
