利用一个核心加热器，可以有效地避免空气成分在较高马赫数时发生冷凝。The dynamic performance of a ram air system will vary with mach number and altitude and this tends to follow the aerodynamic characteristics of the missile .像导弹空气动力特性一样，冲压空气式系统的动态特性随马赫数和...

MACH NUMBER and AIRSPEED vs ALTITUDE MACH NUMBER is defined as a speed ratio, referenced to the speed of sound, i.e. MACH NUMBER ' Velocity of Interest Velocity of Sound (at the given atmospheric conditions) [1] Since the temperature and density of air decreases with altitude, so does ...
By definition, at Mach 1, the local flow velocityuis equal to the speed of sound. At Mach 0.65,uis 65% of the speed of sound (subsonic), and, at Mach 1.35,uis 35% faster than the speed of sound (supersonic). Pilots of high-altitudeaerospacevehicles use flight Mach number to express...

If the mach number is >> 1, the flow speed is much higher than the speed of sound - and the speed is hypersonic.Example - Calculating an Aircraft Mach NumberAn aircraft flies at speed 500 mph at an altitude of 35000 ft. The surrounding temperature is -60 oF....
The altitude hold mode of the YF-12A airplane was modified to include a high-pass-filtered pitch rate feedback along with optimized inner loop altitude rate proportional and integral gains. An autothrottle control system was also developed to control either Mach number or KEAS at the high-speed...
