Book excerpt: An investigation was conducted to obtain nozzle performance data with relatively large-scale models at pressure ratios as high as 120. Conical convergent-divergent nozzles with divergence angles alpha of 15, 25, and 29 deg. were each tested at area ratios of approximately 10, 25, and 40. Heated air (1200 F) was supplied at the nozzle inlet at pressures up to 145 pounds per square inch absolute and was exhausted into quiescent air at pressures as low as 1.2 pounds per square inch absolute. Thrust ratios for all nozzle configurations are presented over the range of pressure ratios attainable and were extrapolated when possible to design pressure ratio and beyond. Design thrust ratios decreased with increasing nozzle divergence angle according to the trend predicted by the (1 + cos alpha)/2 parameter. Decreasing the nozzle divergence angle resulted in sizable increases in thrust ratio for a given surface-area ratio (nozzle weight), particularly at low nozzle pressure ratios. Correlations of the nozzle static pressure at separation and of the average static pressure downstream of separation with various nozzle parameters permitted the calculation of thrust in the separated-flow region from unseparated static-pressure distributions. Thrust ratios calculated by this method agreed with measured values within about 1 percent.

This book was released on 1955 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted to determine the effects on internal performance of several geometric variables that were intended to produce a short, high-performance convergent-divergent nozzle. It was found that shortening the convergent section by either changing its shape or decreasing the throat-contour radius had no effect on thrust coefficient. It was also found that a nozzle with a short conical divergent section had a higher thrust coefficient than a nozzle with either a stepped or contoured divergent section of approximately equal length.
