While the influence of flight height on the RCS is greatly enhanced as the Mach number increases, as shown in Figure 7(b), large changes occur in the range of 10 GHz~14 GHz with an increase in flight height for a velocity at 24 Mach.
However, it is time-consuming to generate the training data via any direct CFD simulations when both Mach number and mean angle of attack are taken into consideration.
Equation (13) shows that the Mach number of the nozzle exit only relates to the ratio of the sectional area between the inlet and outlet.
During calculations the Alfven Mach number, [M.sub.A], was varied from zero (static plasma) to values at which we obtained unstable solutions.
The effects of parameters such as Mach number, dynamic pressure, and temperature on aerodynamic nonlinearity are discussed in Section 3.
This study involves the comparison of scramjet inlet performances, which is specifically designed for the Mach number of 10, under different flight regimes.
With the ELD-X, Hornady designers used Doppler radar measurements every 2 to 3 feet to generate precise drag coefficient (Cd) versus Mach number plots.
The only gotcha is that there might be a small note about initial speeds on the procedure that might say something like "Descend via Mach number until intercepting 280 knots.
To distinguish between compressible and incompressible flow in gases, the Mach number (the ratio of the speed of the flow to the speed of sound) must be greater than about 0.3 before significant compressibility occurs.
In recognition of his work, the Mach number (the ratio between the speed of an object and the speed of sound) is named in his honor.
Settings Buoyancy Model Non Buoyant Domain Motion Stationary Reference Pressure 1.0000e+00 [atm] Heat Transfer Model Isothermal Fluid Temperature 2.5000e+01 [degrees]C (82 [degrees]F) Turbulence Model k epsilon Turbulent Wall Functi Scalable Assumption: the Mach number can be used to determine if a flow can be treated as an incompressible flow.
Some of the increments we achieved when testing the car were as little as 0.01 of a Mach number, because I feared the onset of unsteady flow characteristics.
