Gulfstream Aerospace is actively researching sonic boom mitigation techniques and studying the noise impact of sonic over-flights to people on the ground, having verified the ability of its patented Quiet Spike extendable nose probe to turn a “boom” into a muted “rumble.”
A vehicle is said to be flying supersonically if it is moving through the atmosphere at a speed greater than the local velocity of sound. The speed of sound (Mach 1) varies with temperature and pressure, and at sea level and 59F (15C), is about 760 mph. As temperature reduces with altitude up to the tropopause at around 36,000. ft. and a temperature of -69.7F, the speed of sound reduces to around 661 mph. at this level.
Prospects for the go-ahead of an ambitious oblique flying wing (OFW) “X-plane” supersonic demonstrator appear to have been boosted by completion of wind tunnel tests that, according to Northrop Grumman officials, prove the design is both workable and “robust.”
