This motivated a continuum mechanics analysis of supersonic mode III cracks by Yang. Recent progress in the theoretical understanding of hyperelasticity in dynamic fracture has shown that supersonic crack propagation can only be understood by introducing a new length scale, called χ; which governs the process of energy transport near a crack ...
Observers hear nothing until the shock wave, on the edges of the cone, crosses their location. Mach cone angle NASA data showing N-wave signature. [1] Conical shockwave with its hyperbola-shaped ground contact zone in yellow. A sonic boom is a sound associated with shock waves created when an object travels through the air faster than the speed ...
Although Concorde and the Tu-144 were the first aircraft to carry commercial passengers at supersonic speeds, they were not the first or only commercial airliners to break the sound barrier. On 21 August 1961, a Douglas DC-8 broke the sound barrier at Mach 1.012, or 1,240 km/h (776.2 mph), while in a controlled dive through 41,088 feet (12,510 m).

Boom Supersonic's XB-1 is a stepping stone in its plan to develop a commercially viable supersonic airliner, the Overture, capable of carrying 64-80 passengers across the Atlantic in about 3-1/2 ...
XB-1 became the first American-made private supersonic jet to fly faster than the speed of sound as Boom Supersonic works toward building a fleet of supersonic jets for commercial air travel.
But Menards announced later in the year that its expansion plans were being put on hold because of a general economic downturn at that time. [5] In 2012, a new Hollywood Casino was constructed and opened near the site of Westland Mall, spurring new growth in the surrounding area that had become economically depressed. Plans were announced in ...
