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 ...
The sound of a sonic boom depends largely on the distance between the observer and the aircraft shape producing the sonic boom. A sonic boom is usually heard as a deep double "boom" as the aircraft is usually some distance away. The sound is much like that of mortar bombs, commonly used in firework displays. It is a common misconception that ...
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).
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.
Boom Supersonic aims for its future, larger Overture commercial aircraft to be capable of flying at a cruising speed of Mach 1.7, the Denver-based company said. It is supposed to be two times ...
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 ...
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 ...
Fracture is the appearance of a crack or complete separation of an object or material into two or more pieces under the action of stress.The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid.
