Book Description
Abstract: Local and average blade temperatures were calculated for two stationary air-cooled turbine blades with 10 tubes and 13 fins forming the internal heat-transfer surfaces. These temperatures were calculated using previously published NACA temperature-distribution equations and the most recent theories for determining heat-transfer coefficients, including for the first time the allowance for effects of variable wall temperature on gas-to-blade heat-transfer coefficients at the leading and trailing sections of turbine blades. Comparison of calculated and experimental blade temperatures, for gas temperatures of 300° and 1000°F, resulted in good agreement.
Experimental Investigation of the Cooling Characteristics of Transpiration Air-cooled Turbine Blades in a High Temperature Gas Cascade

Book Description
An experimental investigation was conducted on a transpiration air cooled stator cascade to evaluate the heat transfer characteristics, to observe the temperature patterns, and to verify the existing transpiration cooling theory for hot gas streams ranging in temperature from 1600 to 2050 F.A total of 49 hours and 55 minutes of cascade testing were logged. Hot gas Reynolds numbers computed at ten span-wise positions on the blade varied between 7800 on the pressure side near the leading edge and 288,000 at the convex side just upstream of the trailing edge. Hot gas weight flows of 2.46 lb/sec and 1.64 lb/sec were directed at the cascade section. A comprehensive analysis of the data accumulated along with detailed descriptions of the test facility, the component test hardware, and the problems associated with instrumentation is presented.
Effect of Chord Size on Weight and Cooling Characteristics of Air-cooled Turbine Blades

Book Description
An analysis has been made to determine the effect of chord size on the weight and cooling characteristics of shell-supported, air-cooled gas-turbine blades. In uncooled turbines with solid blades, the general practice has been to design turbines with high aspect ratio (small blade chord) to achieve substantial turbine weight reduction. With air-cooled blades, this study shows that turbine blade weight is affected to a much smaller degree by the size of the blade chord.
