Fibers with helical structures, which fall into the category of complex mediums, have also attracted investigators primarily because the angle of pitch of the helix in use exhibits dominant characteristics to alter the wave propagation characteristics of the guide.
Further, the propagation of power can be controlled by varying the angle of pitch of the introduced helical wraps.
Also, the introduced values of the angle of pitch are taken to be 0[degrees], 45[degrees] and 90[degrees].
Then there's a Shotgun Combo Gauge (used to measure length of pull, drop at comb, angle of pitch
and cast), the Boremaster (for measuring bore and choke dimensions, chamber length and diameter, forcing-cone length and dimensions and barrel-wall thickness), along with various fitted carrying cases and cleaning items.
This approach will make it possible to ensure motion with the increased angle of pitch
and velocity in the initial stage, which will lead to the quick AUV moving in the vertical plane.
Static flux (open circles) is very low when the blade is parallel to flow (lower than the small-angle values for either the plate or the flow-protected blade), but increases with increasingly positive angle of pitch
to values higher than those for the other models.
