Hierarchical optimization method of supersonic low sonic boom configuration
Hangkong gongcheng jinzhan, 2023 Sonic boom suppression is a key technology that must be broken through in the development of a new generation of supersonic civil aircraft. The reasonable design of configuration parameters can make the aircraft have good sonic boom characteristics.

A low-boom and low-drag design method for supersonic aircraft and its applications on airfoils
Advances in Aerodynamics, 2021 Sonic boom reduction has been an urgent need for the development of future supersonic transport, because of the heavy damage of noise pollution. This paper provides a novel concept for supersonic aircraft to reduce the sonic boom and drag coefficient ...

Animal Response to Sonic Boom [PDF]
The Journal of the Acoustical Society of America, 1971 Experiments and observations have been made to test the effects of sonic booms (real or simulated) on mink, horses, dairy and beef cattle, sheep, turkeys, pheasants, and chickens. Several of these tests were carried out under field conditions. Results of some of these trials are considered similar to the sensory effects of sonic booms on humans. In one

Seismic detection of sonic booms [PDF]
The Journal of the Acoustical Society of America, 2002 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 50 000 square kilometers, is used to map primary and secondary sonic boom carpets.

Status of knowledge of sonic boom [PDF]
The Journal of the Acoustical Society of America, 1979 Numerous sonic boom studies were accomplished in the last two decades as a result of increased operations of high performance military aircraft, the proposed US/SST, and the anticipated entry of the Concorde into commercial airline service. Much in the way of documentation of the phenomena and its effects was suitably summarized by the society in the ...

Numerical Investigation of Influence of Mesh Property in Nearfield Sonic Boom Prediction [PDF]
Xibei Gongye Daxue Xuebao, 2018 To investigate the influence of mesh property in nearfield sonic boom prediction, the over-pressures of several typical configurations are commutated and analyzed with an in-house Reynolds Average Navier-Stokes solver.

The Origin and Physico-Chemical Properties of Some Unusual Earth Rock Fragments
Applied Sciences, 2022 In this paper, several researches were undertaken related to a violent phenomenon, characterized by a sonic boom, felt on an area of at least 500 km2, shortly followed by the fall of rock fragments that were then recovered from the ground.
