Although only one unsteady aerodynamic simulation under FWGN excitation is required under each flight condition, it is still time-consuming to generate the training data to capture the dynamic characteristics of an unsteady aerodynamic system in the mean angle of attack and
Mach number space.
Compared to the HC1 results, the modern design introduces effects of compressibility due to the increased
Mach number (M = 0.47 to 0.627).
Motivated by this, we compared the characteristics of the hot jet using six different nozzles, including profiles of velocity,
Mach number, vorticity, species concentration, pressure and temperature distributions, as well as shock structures for the C-D nozzles.
(ii) The KH instability of the kink mode (m = [+ or -] 1) starts at Alfven
Mach numbers very close to the predicted ones.
At lower temperatures of T/[T.sub.cr] = 0 and T/[T.sub.cr] = 2 shown in Figures 2(a) and 2(b), respectively, the panel undergoes the LCO motions in a range of dynamic pressure of interest, and the curves in terms of panel positive deflection peak versus dynamic pressure at
Mach number of 5, 10, and 15 are presented.
This study involves the comparison of scramjet inlet performances, which is specifically designed for the
Mach number of 10, under different flight regimes.
where the variables u', v', P' and p' are the disturbance values of the velocity along axis x, and velocity along axis y, pressure and density, respectively; A, p, y, Ma, and Re are amplitude, wave number, generalized frequency freestream
Mach number, and Reynolds number, respectively.
In a 26-inch fully retracted aft position, at the design cruise
Mach number of 3.2, an oblique shock system exists with the lead shock stretched between the cone's apex and the nacelle lip, to yield a maximum total pressure recovery of 40:1.
Specifically, WE seek to minimise the convective
Mach numbers of turbulent eddies throughout the jet flow field.
Figure 6(a) is the transmission coefficient under different
Mach numbers when incident wave is normal to surface.
Mach number is one of the critical parameter in the gas atomization process.
For example, Blackman tells the story of one of the worst of the early problems: the Vulcan was longitudinally unstable at speeds above .88 indicated
Mach number. He describes flight testing the fix, a Mach trimmer that would automatically make the control inputs at high
Mach numbers feel natural to the pilot.
