This book was released on 2000 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NASA Langley Configuration Aerodynamics Branch has conducted an experimental investigation to study the static performance of innovative thrust reverser concepts applicable to high-bypass-ratio turbofan engines. Testing was conducted on a conventional separate-flow exhaust system configuration, a conventional cascade thrust reverser configuration, and six innovative thrust reverser configurations. The innovative thrust reverser configurations consisted of a cascade thrust reverser with porous fan-duct blocker, a blockerless thrust reverser, two core-mounted target thrust reversers, a multi-door crocodile thrust reverser, and a wing-mounted thrust reverser. Each of the innovative thrust reverser concepts offer potential weight savings and/or design simplifications over a conventional cascade thrust reverser design. Testing was conducted in the Jet-Exit Test facility at NASA Langley Research Center using a 7.9% scale exhaust system model with a fan-to-core bypass ratio of approximately 9.0. All tests were conducted with no external flow and cold, high-pressure air was used to simulate core and fan exhaust flows. Results show that the innovative thrust reverser concepts achieved thrust reverser performance levels which, when taking into account the potential for system simplification and reduced weight, may make them competitive with, or potentially more cost effective than current state-of-the-art thrust reverser systems.

Book Synopsis Static Internal Performance of a Nonaxisymmetric Vaned Thrust Reverser with Flow Splay Capability by : National Aeronautics and Space Administration (NASA)
Download or read book Static Internal Performance of a Nonaxisymmetric Vaned Thrust Reverser with Flow Splay Capability written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-10 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted in the Static Test Facility of the Langley 16-Foot Transonic Tunnel on a dual-port, nonaxisymmetric, block-and-turn type thrust reverser model with vane cascades in the reverser ports which turned the flow in the splay direction and aided in turning the flow in the reverse direction. Splaying reverser flow is a method of delaying to lower landing ground roll speeds the reingestion of hot exhaust flow into the inlets. Exhaust flow splay can also help prevent the impingement of hot exhaust gases on the empennage surfaces when the reverser is integrated into an actual airframe. The vane cascades consisted of two sets of perpendicular vanes with a variable number of turning and splay vanes. A skewed vane box was also tested which had only one set of vanes angled to provide both turning and splay. Vane cascades were designed to provide different amounts of flow splay in the top and bottom ports. Inner doors, trim tabs, and an orifice plate all provided means of varying the port area for reverser flow modulation. The outer door position was varied as a means of influencing the flow reverse angle. Nozzle pressure ratio was varied from 1.75 to approximately 6.00. Bangert, Linda S. and Leavitt, Laurence D.

Book Synopsis From Archangel to Senior Crown by : Peter W. Merlin
Download or read book From Archangel to Senior Crown written by Peter W. Merlin and published by AIAA (American Institute of Aeronautics & Astronautics). This book was released on 2008 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lockheed Blackbirds hold a unique place in the development of aeronautics. In their day, the A-12, YF-12, M-21, D-21, and SR-71 variants outperformed all other jet airplanes in terms of altitude and speed. Now retired, they remain the only production aircraft capable of sustained Mach 3 cruise and operational altitudes above 80,000 feet.This is the first book to address the technical aspects of these incredible aircraft. The author describes the design evolution of the Blackbird, from the Archangel to the Senior Crown (the Air Force's SR-71.) He describes in detail the construction and materials challenges faced by Lockheed, as well as the Blackbird's performance characteristics and capabilities.A NASA historian, the author describes NASA's role in using the aircraft as a flying laboratory to collect data on materials, structures, loads, heating, aerodynamics, and performance for high-speed aircraft. The reader will benefit from the technical and programmatic lessons learned.This volume was produced in cooperation with the National Aeronautics and Space Administration.
Book Synopsis STOL Transport Thrust Reverser/Vectoring Program by :
Download or read book STOL Transport Thrust Reverser/Vectoring Program written by and published by . This book was released on 1973 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design studies were conducted of thrust reverser and thrust vectoring systems for STOL tactical transports to evolve systems properly integrated with the aircraft. The studies included configuration design, performance, and weight analyses of feasible thrust reverser and thrust vectoring concepts. Test plans were developed for static tests of the most promising concepts. Following Air Force approval of the test plans, test model hardware were fabricated. Model tests were conducted of a fan thrust reverser that exhausts all of the fan flow through cascades installed in the upper 180 degrees sector of the nacelle, and an external deflector/target TR/TV system that combines the functions of thrust vectoring and reversing into a single mechanism. Scaling relationships were used to correct the data to full-scale performance, and data correlations were developed for the external/target model as a function of geometric parameters and nozzle pressure ratio.
