For comparison: the required speed for low Earth orbit is approximately 7.5 km/s = Mach 25.4 in air at high altitudes. 【参考译文】为了进行比较:进入低地球轨道所需的速度约为7.5公里/秒,在高空中的音速情况下相当于马赫25.4。 At transonic speeds, the flow field around the object includes both su...
Its speed and ability to operate at high altitudes served as a defensive feature; when attacked by surface-to-air missiles, the pilot needed only to accelerate to avoid being struck. Only 32 SR-71’s were operated duri...

524lbf thrust each and 22,494lbg thrust each with afterburner. Maximum speed was listed at Mach 3.2 (2,170mph) at high altitude and about 740mph at low altitudes. Range was limited
Oblique detonations near the low flight speed/altitude boundary have been studied. Unsteady waves can be re-stabilized by decreasing the fuel-air equivalence ratio. A Mach number analysis at the steady boundary clarifies the stabilization mechanism. A flow-combustion criterion is proposed for the ...
