M is the Mach numberu is velocity of the moving aircraft andc is the speed of sound at the given altitude (more properly temperature)【参考译文】M是马赫数,u是飞行器的速度,c是给定高度(更准确地说是温度)下的音速。 and the speed of sound varies with the thermodynamic temperature as: 【参考...
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 词汇Mach number 释义 Mach number n. Number indication the ratio of speed of a body to the speed of sound at a given altitude. 马赫值。在一定的高度,物体的飞行速度与音速之比值。
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 ...
OPERATIONSATFORMThe ARA Grob 520T "Egrett" aircraft (VH-ARA) is currently the only manned platform available to the scientific community for sustained low Mach-number flight at altitudes between 10 and 15km. It is a fully composite two-seater aircraft, utilizing a very high aspect ratio wing...
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....

Mach number is useful because the fluid behaves in a similar way at the same Mach number. So, an aircraft traveling at Mach 1 (340.3 m/s, 761.2 mph, 1,225 km/h) will experience shock waves in much the same manner as when it is traveling at Mach 1 at 11,000 m (36,000 ft), ...
The Mach number M is defined as the ratio of the true airspeed V to the speed of sound a in air at the flight altitude: (15)M=V/a For the calibration of Machmeters, the Mach number can be related to the ratio of the impact pressure to the static pressure qc/P by the following ...
