Springer Handbook of Mechanical Engineering
These changes in the airflow have a significant effect on the airplane lift and drag
curves in the various Mach number ranges. For airplanes that operate entirely
within the subsonic speed range, there are no significant effects of
compressibility ...

Gas Turbine Engineering Handbook
The positive prewhirl decreases the relative Mach number at the inducer inlet.
However, negative prewhirl increases it. A relative Mach number is defined by
W1 Mrel = a1 (6-7) where: Mrel = relative Mach number W1 = relative velocity at
an ...

The single most important parameter in the analysis of the compressible fluids is
the Mach Number (M), named after the nineteenth century Austrian physicist
Emst Mach. The Mach number (a dimen- sionless measure of compressibility) is
...

Collisionless Shocks in the Heliosphere: Reviews of Current ...
Different shock shapes are shown for constant sonic Mach number and varying
Alfvenic Mach number. As the magnetosonic Mach number AfMS" approaches
that used in the usual, or pure, gas dynamic calculation, the shock surface of the

Therefore, when the dynamic pressure is divided by the modulus of elasticity, we
obtain a dimensionless quantity equal to one-half of the square of the free stream
Mach number, M, defined by M = VT/a, (2.2-3) where a is the speed of sound at ...

The alternative semi-empirical method based upon LES allows for the variation of
K with Mach number and lift coefficient, CL- A 100% LES would completely
prevent flow separation and yield the maximum Oswald's efficiency (e = 1).
However ...

Flight Theory and Aerodynamics: A Practical Guide for ...
Subsonic aircraft do not have these design changes and will experience
difficulties if the critical Mach number is exceeded. This discussion also applies to
subsonic aircraft and helicopters, if they venture into the transonic region of flight,
...

Principles of Helicopter Aerodynamics with CD Extra
A good lift-to-drag ratio over a wide range of Mach number. This will give the rotor
a low profile power consumption and the helicopter a low autorotative rate of
descent. 4. A low pitching moment. This will help minimize blade torsion
moments, ...

If the inlet flow is axial with Mach number 0.70 and the inlet stagnation
temperature on a sea-level test bed is 288 K, find the relative velocity and relative
Mach number at the tip of the first stage fan. (Ans: 1 4022 rpm, 549 m/s, M =1 .69)
