Cooling of Gas Turbines, 2, Effectiveness of Rim Cooling of Blades

Cooling of Gas Turbines, 2, Effectiveness of Rim Cooling of Blades

Date: September 20, 1945
Creator: Wolfenstein, Lincoln; Meyer, Gene L. & McCarthy, John S.
Description: An analysis of rim cooling, which cools the blade by condition alone, was conducted. Gas temperatures ranged from 1300 degrees to 1900 degrees F and rim temperatures from 0 degrees to 1000 degrees F below gas temperatures. Results show that gas temperature increases up to 200 degrees F are permissible provided that the blades are cooled by 400 degrees to 500 degrees F below the gas temperature. Relatively small amounts of blade cooling, at constant gas temperature, give large increases in blade life. Dependence of rim cooling on heat-transfer coefficient, blade dimensions, and thermal conductivity is determined by a single parameter.

Correlation of mixture temperature data obtained from bare intake-manifold thermocouples

Correlation of mixture temperature data obtained from bare intake-manifold thermocouples

Date: January 1, 1946
Creator: White, H. Jack & Gammon, Goldie L
Description: A relatively simple equation has been found to express with fair accuracy, variation in manifold-charge temperature with charge in engine operating conditions. This equation and associated curves have been checked by multi cylinder-engine data, both test stand and flight, over a wide range of operating conditions. Average mixture temperatures, predicted by the equations of this report, agree reasonably well with results within the same range of carburetor-air temperatures from laboratories and test stands other than the NACA.
