Book Description
Abstract: The results presented herein were obtained in a transpiration cooling investigation of a double wedge of 40° included angle having a porous stainless-steel specimen inserted flush with the top surface of the wedge. Nitrogen and helium were used as coolants, and tests were conducted for stagnation temperatures ranging from 1,295° to 2,910° F. The data for both the nitrogen and helium coolants indicated greater cooling effectiveness than predicted by theory and were in good agreement with the results for an 8° cone tested at a stagnation temperature of 600° F.

Book Description
An investigation of transpiration cooling was conducted in the preflight jet of the Langley Pilotless Aircraft Research Station at Wallops Island, Va. The model consisted of a double wedge of 40 degrees included angle having a porous stainless-steel specimen inserted flush with the top surface of the wedge. The tests were conducted at a free-stream Mach number of 2.0 for stagnation temperatures ranging from 1,295 F to 2,910 F. Nitrogen and helium were used as coolants and tests were conducted for values ranging from approximately 0.03 to 0.30 percent of the local weight flow rate. The data for both the nitrogen and helium coolants indicated greater cooling effectiveness than that predicted by theory and were in good agreement with the results for an 8 degree cone tested at a stagnation temperature of 600 F. The results indicate that the helium coolant, for the same amount of heat-transfer reduction, requires only about one-fourth to one-fifth the coolant flow weight as the nitrogen coolant. (Author).
