Book External stream Effects on Gross Thrust and Pumping Characteristics of Ejectors Operating at Off design Mach Numbers

Download or read book External stream Effects on Gross Thrust and Pumping Characteristics of Ejectors Operating at Off design Mach Numbers written by Alfred S. Valerino and published by . This book was released on 1956 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was concluded in the NACA Lewis 8- by 6-foot supersonic tunnel to determine the external-stream effects on the gross thrust and pumping characteristics of ejectors operating at off-design Mach numbers. Ejectors having diameter ratios of 1.16, 1.45, and 1.70 were tested over a range of primary-jet pressure ratios and secondary weight flows at free-stream Mach numbers of 0, 0.63, 1.5, 1.8, and 2.0. Design Mach numbers of the 1.16-, 1.45-, and 1.70-diameter-ratio ejectors, obtained by assuming an inlet total-pressure recovery on a current-production engine, were approximately 1.7, 2.2, and 2.6, respectively. The spacing ratio of the 1.70-diameter-ratio ejector was varied from 0 to 1.19.

This book was released on 1954 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted in the 8- by 6-foot supersonic wind tunnel on a cylindrical-shroud ejector (diameter ratio of 1.2 and spacing ratio of 0.80. Data were obtained at weight-flow ratios of 0.014, 0.095, 0.234, and 0.380 for primary pressure ratios ranging from 1 to 16 and at free-stream Mach numbers for 0.1, 0.6, 1.6, and 2.0.

Book Effect of Jet Convergence Angle on the Performance of Annular Nozzles with Semitoroidal Concave Plugs at Mach Numbers Up to 1 82

Download or read book Effect of Jet Convergence Angle on the Performance of Annular Nozzles with Semitoroidal Concave Plugs at Mach Numbers Up to 1 82 written by Charles E. Mercer and published by . This book was released on 1972 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of an investigation at static conditions and at Mach numbers up to 1.82 are presented for 12 nozzle configurations which have jet convergence angle and jet throat area as geometric parameters. The variation of jet convergence angle from 15 to 40 deg had little effect on the performance of the nozzles having the large value of primary throat area; however, increasing jet convergence angle generally had an adverse effect on performance of the nozzles having the smaller value of primary throat area. The performance of the nozzle configurations with the larger primary throat area is competitive with nozzles designed for operation over the Mach number range.
