Book excerpt: Abstract: Cooling data from this experimental afterburner are successfully correlated over a range of Reynolds number based on the distance downstream of the leading edge of the porous wall. Calculations based on the correlation indicate that the combustion-chamber cooling-air requirements for an exhaust-gas temperature of 3700° R are only 16 percent of the air required for conventional forced-convection cooling. The cooling-air requirements were nearly independent of flight condition, but close control of cooling-air pressure is required at high flight speeds.

Book excerpt: Abstract: An experimental investigation was conducted to obtain information on air-flow uniformity and pressure-level effects for various meshes of stainless-steel corduroy wire cloth, and permeability and strength data for a 20- by 20-mesh stainless-steel wire cloth. It was found that close control of the wire cloth thickness yielded sufficiently uniform air flow and that available methods may be used to predict the effect of pressure level. Permeability and strengths of the 20- by 20-mesh wire cloth were similar to those already available from other meshes. The reduced tensile strength of the 20- by 20-mesh wire cloth in the direction of the primary stresses is one and a half to three times as great as the strength of the best porous sintered materials presently available.

This book was released on 1951 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: Transpiration and film cooling promise to be effective methods of cooling gas-turbine blades; consequently, analytical and experimental investigations are being conducted to obtain a better understanding of these processes. This report serves as an introduction to these cooling methods, explains the physical processes, and surveys the information available for predicting blade temperatures and heat-transfer rates. In addition, the difficulties encountered in obtaining a uniform blade temperature are discussed, and the possibilities of correcting these difficulties are indicated. Air is the only coolant considered in the application of these cooling methods.

This book was released on 1956 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of producing uniform air flow through a calendered or cold-rolled sheet of brazed stainless-steel corduroy wire cloth was investigated on 20x250 mesh cloth in regions of low permeability. The effect of the exit pressure level was determined at various exit pressures on 20x200, 20x250, and 28x500 mesh wire cloth. In addition, permeability and strength datta were obtained for 20x2000 mesh wire cloth to supplement results previously published on other meshes.
