| Working with NASA, Gulfstream is testing out a device it dubs ``Quiet Spike,'' a telescoping pole that would be mounted on a jet's nose in hope of reshaping and quieting the pressure wave that causes sonic booms. In ultralow-velocity zones, seismic pressure waves slow 5 to 10 percent, sws Mao. We've done very advanced modeling--for example, computational fluid dynamics models of the pressure wave propagation from bomb blasts in urban environments--to model the expected damage from various types of attacks you would expect from terrorists using both conventional and unconventional methods," he said. |
