Definitions

  • Figure 2 is a graDhi-cal representation of a normalized pressure pattern plotted in relation to the length of a probe, and specifically related to pressure ports in the negative pressure regions of the probe in Figure 1;
  • barrel portion 14 has a forward external taper portion 25 which is of conventional design, and which blends into the first corrugated (or wavy, or undulating) wall portion 26 in which the ports 23 and 24 are defined.
  • the pitot-static probe barrels are of uniform, increasing or decreasing diameter back to the mounting strut.
  • a double annular corrugation or wave with two major annular peaks 27 and 28 and two major annular valleys 29 and 30 is formed in the probe wall between the forward external taper portion 25 and an aft cylindrical surface portion 31, which is in turn attached to the strut 13.
  • the two corrugation or wave pattern between the forward taper portion 25 and the aft cylindrical surface 31 forms a transition section between these two probe portions that is a smooth, streamlined shape.
  • the diameters of peaks 27 and 28 are substantially equal to the diameter of cylindrical section 31, as shown.
  • a second bulkhead 32 is positioned in the barrel portion 14 of the probe to seal off chamber 22.
  • bulkhead 32 is also shown in the cut away between two negative pressure regions on the probe.
  • An alternate location for bulkhead 32 is shifted slightly aft as shown in Figure 3 between two positive pressure regions on the probe.
  • a third bulkhead 33 as shown is spaced rearwardly from second bulkhead 32 to define a second static pressure chamber 34.
  • the second static chamber 34 is completely pressure isolated from the chamber 22.
  • the ports should be kept away from the strut because the pressure changes due to change in Mach adjacent the strut are intense.
  • the cause of the intense change is that the strut is an abrupt change in section of the probe.
  • the maximum angle of a tangent line on the corrugated (or wavy or undulating) wall surface, with respect to the axis of the probe should be kept to a minimum.
  • a nominal maximum angle is about 8 but can vary from about 3o to 12o. The abruptness of change in the probe cross section size is minimized.
