This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characteristics were determined for a twin-engine jet aircraft with the following configurations: (1) eight-lobe exhaust noise suppressors, (2) eight-lobe nozzles and ejectors, and (3) the unmodified aircraft. In-flight sound pressure levels measured on the ground under the flight path were reduced 5 to 6 decibels by the suppressors. Similar reductions in perceived noise level occurred. Increases in total drag coefficient of 3 and 7 percent and decreases in specific range of 5 to 14 percent were found to result from the suppressor configurations. (Author).

This book was released on 1963 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acoustical performance requirements are developed for portable ground runup turbojet engine noise suppressors. The criteria from which the per formance requirements are developed are based fundamentally on the known data regarding sound induced temporary and permanent hearing impair ment, communication criteria developed and the results of a noise exposure survey carried out at twenty-two Air Force bases. A main result is that a residual noise level rather than a noise reduction method of acoustical evaluation is recommended. The experience and data of past suppressor evaluations is used to define the current technology of noise suppressor design and to outline areas for future research and development. Also developed are standard pro cedures and specifications for the acoustical evaluation of a portable ground runup noise suppressor. (Author).
