This book was released on 2018-07-03 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental results from a wind tunnel test conducted to investigate propulsion/airframe integration (PAI) effects are presented. The objectives of the test were to examine rough order-of-magnitude changes in the acoustic characteristics of a mixer/ejector nozzle due to the presence of a wing and to obtain limited wing and nozzle flow-field measurements. A simple representative supersonic transport wing planform, with deflecting flaps, was installed above a two-dimensional mixer/ejector nozzle that was supplied with high-pressure heated air. Various configurations and wing positions with respect to the nozzle were studied. Because of hardware problems, no acoustics and only a limited set of flow-field data were obtained. For most hardware configurations tested, no significant propulsion/airframe integration effects were identified. Significant effects were seen for extreme flap deflections. The combination of the exploratory nature of the test and the limited flow-field instrumentation made it impossible to identify definitive propulsion/airframe integration effects.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was performed to study the characteristics of the flow in a two-dimensional air ejector in which the center stream entered the mixing chamber at a Mach number of 1.90 while the velocity of the secondary flow was varied from zero to Mach 0.7. Mass flow ratios of the ejector were approximately equal when the pressures of the two streams were equal at the entrance to the mixing chamber. The chamber had a rectangular cross section and converged slightly; its length was equal to 16 times the width. Pressures measured at the walls and the centerline of the flow indicated that a maximum static pressure was reached at 8 widths of the chamber downstream of the nozzle when the flow was completely expanded at the nozzle exit. The maximum static pressure was achieved in less distance for the overexpanded condition and took longer for the underexpanded condition. The flow was always subsonic by the time the maximum pressure position was reached except in the underexpanded case, where the flow remained supersonic throughout the chamber and the maximum pressure was located at the exit to the chamber.

This book was released on 1965 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The turbulent mixing region of a two-dimensional, supersonic, air-air ejector system was experimentally investigated utilizing an interferometer. Density distributions for the two-stream mixing region within the ejector duct were established for 6 different test configurations. Similarity of the density distributions was indicated for mixing region cross sections as close as one nozzleexit hydraulic diameter from the nozzle. Density profiles at successive downstream duct locations were plotted to show the spread of the mixing region. The effect of normal and oblique shocks on the rate of spread of the mixing region was found to be small. In addition, ejector performance data and techniques for spark lamp photography are presented. It is concluded that the interferometer could be effectively utilized to help determine the transport coefficients of ejector system turbulent mixing processes. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Since 1986, NASA and the U.S. aerospace industry have been assessing the economic viability and environmental acceptability of a second-generation supersonic civil transport, or High Speed Civil Transport (HSCT). Environmental acceptability in terms of airport community noise and economic viability are critical elements in this endeavor. Development of a propulsion system that satisfies strict airport noise regulations (FAR36 Stage III levels), at acceptable performance and weight, is critical to the success of any HSCT program. Two-dimensional mixer-ejector (2DME) exhaust systems are one approach in achieving this goal. In support of HSCT development, GEAE (GE Aircraft Engines), under contract to the NASA Glenn Research Center, conducted this test program at the NASA Langley 16 ft transonic wind tunnel to evaluate the cold aerodynamic performance aspects of the 2DME exhaust system concept. The effects of SAR (SAR, suppressor area ratio, = mixed-flow area/primary nozzle throat area), MAR (MAR = overall exhaust system exit/mixing-plane area), flap length, CER (suppressor chute expansion ratio), chute alignment, and free stream Mach number were investigated on a 1/11th cold aerodynamic scale model of a 2DME exhaust system.
