Three-hole pressure probe comb

摘要: The invention belongs to the technical field of pressure testing and discloses a three-hole probe comb. comb comprises at least three probes, support rod guiding pipes, wherein number probes is determined according measurement requirement, have same geometrical shape, are flat trapezoids fixed in different display direction positions respectively, sensing holes formed windward side each communicated with pipes packaged channel rod, other end pipe passes through lead out tail probe. can measure total pressure, static deflection angles mach numbers multiple space simultaneously wind tunnel calibration applicable distribution impeller mechanical blade row inlet, outlet interstage two-dimensional flow incoming parameters along height. Compared existing for measuring fields, simultaneously, time shortened greatest extent, test cost reduced.
