Sonic Booms Resulting from Extremely Low-altitude Supersonic Flight: Measurements and Observations on Houses, Livestock and People
Author: C. W. Nixon
Publisher:
ISBN:
Category : Sonic boom
Languages : en
Pages : 36
Book Description
Sonic booms generated by F-4C aircraft flying low-level terrain- following profiles during Joint Task Force II operations near Tonopah, Nevada, were recorded under and near the flight tracks, and responses of structures, animals, and people were observed. Recorded overpressures up to 144 psf were analyzed, correlated with available aircraft operations data, and compared with data from different aircraft flying similar profiles. Observations of structures, animals, and people were correlated with the measured overpressures. Results include acquisition of near-field recordings of overpressures generated by the F-4C, the finding that some window glass fragments were propelled a short distance rather than falling directly below the window, an instance in which the measured overpressure of a sonic boom 1 mile to the side of the track far exceeded the predicted value, the finding that livestock (undetermined prior exposure to acoustic stimuli in this situation) did not respond adversely to the sonic booms, confirmation that very intense sonic booms do not harm people directly and the reaffirmation that the selection of site locations for low- level supersonic training missions will continue to pose a problem.

Sonic Booms Produced by United States Air Force and United States Navy Aircraft: Measured Data
Author:

Languages : en
Pages : 318
Book Description
A sonic measurement program was conducted at Edwards Air Force Base. Sonic boom signatures, produced by F-4, F-14, F-15, F-16, F-18, F111, SR-71, and T-38 aircraft, were obtained under the flight track and at various lateral sites which were located up to 18 miles off-track. Thirteen monitors developed by Det 1 AL/BBE were used to collect full sonic boom waveforms, and nine modified dosimeters were used to collect supplemental peak overpressures and the C- weighted Sound Exposure Levels (CSEL) for 43 near steady supersonic flights of the above United States Air Force and United States Navy aircraft. This report describes the measured database (BOOMFILE) that contains sonic boom signatures and overpressures, aircraft tracking, and local weather data. These measured data highlight the major influences on sonic boom propagation and generation. The data from this study show that a constant offset of 26 from the peak overpressure expressed in dB gives a good estimate of the CSEL of a sonic boom.

Book Description
The U.S. Air Force, National Aeronautics and Space Administration, and Federal Aviation Agency have engaged in a joint research program for the purpose of measuring sonic-boom pressure signatures. These measurements are presented for several locations for flight tests of fighter and bomber airplanes in the altitude range from about 10,000 to 75,000 feet and at Mach numbers from 1.1 to 2.0. Data were obtained for a variety of atmospheric wind and temperature gradients and for various flight paths and acceleration rates.
