Sonic Booms from Aircraft in Maneuvers

Sound Propagation of Sonic Booms through Real Atmospheres Emitted from a New Supersonic Business Aircraft

Supersonic air transport generates sonic booms that can affect people, animals and structures. There is a renewed interest in high-speed transport for civilian application. The widely used standard atmosphere for sonic boom prediction is neither capable of describing topographical variation, nor temporal variations, nor the impact of wind on the propagation of a sonic boom. However, within the ...

Seismic detection of sonic booms.

The pressure signals from a sonic boom will produce a small, but detectable, ground motion. The extensive seismic network in southern California, consisting of over 200 sites covering over 50000 square kilometers, is used to map primary and secondary sonic boom carpets. Data from the network is used to analyze three supersonic overflights in the western United States. The results are compared t...

A Laboratory Study of Subjective Annoyance Response to Sonic Booms and Aircraft

Three experiments were conducted to determine subjective equivalence of aircraft subsonic flyover noise and sonic booms. Two of the experiments were conducted in a loudspeaker-driven sonic boom simulator, and the third in a large room containing conventional loudspeakers. The sound generation system of the boom simulator had a frequency response extending to very low frequencies (about 1 Hz) wh...

A Centennial Review of Sub-sonic Transport Aircraft

From Wright Brothers 1903 to present day 2003, aeronautical technology has made a profound progress. This paper demonstrates the outcome of this progress in weight, wing area, and engine thrust in three categories of transport aircraft of short to long range, regional jets, and turbo-prop commuter aircraft. Also the paper includes those aircraft with distinct jump in aeronautical technology. Fe...
