Book excerpt: A development program for a commercial supersonic aircraft and engines was sponsored by the Federal Aviation Administration during a five-year period from 1966 through 1971. The unique propulsion system, an afterburning turbojet, required acoustic suppression techniques to reduce its noise levels to those federally regulated for subsonic aircraft. An acoustic suppression research program was conducted by the General Electric Company to develop technology applicable to prototype and commercial supersonic engines. Primary emphasis was on jet noise suppressor development through model and engine testing. Various systems were studied including ejector pumping, simple mechanical primary and secondary suppressors, fluid injectants, multi-element tube nozzles, acoustically treated ejectors, highly segmented annular plug nozzles, etc. A research study on fundamental jet noise generation and reduction mechanisms was conducted at the General Electric Corporate Research and Development Center. In addition, investigatory tests were conducted for identification of total system noise. Application of a choked inlet and an open A sub 8 exhaust cycle were studied for noise reduction. Source turbomachinery noise generation and suppression through treatment application were investigated. This report summarizes the acoustic and aerodynamic technology with emphasis toward development of guidelines for future applications.

Available in PDF, EPUB and Kindle. Book excerpt: Studies were performed to conclude and refine elements of work begun under the Supersonic Transport Engine Development Program. Three programs were completed in the area of turbomachinery noise: the screening of proposed materials for high temperature acoustic treatment and the extension of suppression design methods to the flows and temperatures typical of turbine exhaust conditions; investigations of multi-stage compressor tip treatment using multiple circumferential grooves; and the prediction and demonstration of the effects of increased turbine axial spacing on noise generation. Detailed analytical studies were made of data from conic and suppressor-type jets, both cold and hot flows, selected from the GE4/SST program. Correlations of aero/acoustic interrelationships were made, and elements of the noise generation mechanisms showing promise for future advanced concepts were identified. Scaling of small model jet noise data to engine size was established, using scaling techniques and accounting for site differences and the added sources present in engine data. (Author).

This book was released on 1972 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supersonic aircraft require propulsion systems that are significantly different from those for present subsonic aircraft. The higher jet velocity of the supersonic aircraft engines will generate more noise during the actual takeoff run than conventional jet transport engines. An applied research program was conducted at The Boeing Company from February 1966 through March 1971 to investigate jet nozzle systems which will suppress jet noise levels from the supersonic transport with minimal thrust loss. These efforts applied to the two prototype supersonic transports being developed at that time as well as the commercial version of the SST that was to follow. The research program indicated that 12 to 20 PNdB noise suppression can be attained with less than 10% thrust loss by using multielement jet nozzle concepts. This report summarizes the test results pertaining to suppressor nozzle noise and thrust characteristics.
