对爆燃的主要特征之一，是火焰的速度大大低于音速的降低旅行。
One of the primary attributes of deflagration is that the flame travels at a speed significantly lower than the speed of sound.
飞行在低于100英尺的超音速飞机制造的音爆，造成的20到144磅的超压，没有对人体造成伤害。
Sonic booms produced by aircraft flying supersonic at altitudes of less than 100 feet, creating between 20 and 144 pounds overpressure, have been experienced by humans without injury.
还有就是要求所有设计的飞行器的速度必须不低于85%音速水平；航程必须达到7000英里；在负载量上无论乘客还是货物必须达到50,000到100；000磅。
And each design has to fly up to 85 percent of the speed of sound; cover a range of approximately 7, 000 miles; and carry between 50, 000 and 100, 000 pounds of payload, either passengers or cargo.
爆燃过程是一种以低于音速而传播的燃烧波。
Deflagration is combustion wave propagating at a velocity less than the speed of sound.
