Robust Design of an Aerodynamic Compensation Pitot-Static Tube for Supersonic Aircraft

local Cp gradient is small in the subsonic regime and is close to zero in the supersonic regime so that in practical application, this pitot-static tube would perform better than an ogival pitot-static tube. The proposed design can be used effectively to compensate for Cp position errors of up to 0:1 in the subsonic regime, by nondimensional stretching of the basic profile, while maintaining zero Cp in the supersonic regime. Computational fluid dynamics is usedinthedesignandanalysisoftheproposedpitot-statictube. ThecompleteMachnumberregime(Machlessthan two)hasbeencomputationallyanalyzedfordifferentprofilesresultingfromstretchingofthebasicprofile,tovalidate the proposed design’s capability. A design methodology is also presented in which a specific pitot-static tube profile canbeextractedfromthegeneralnondimensionalprofiletoaerodynamicallycompensateforaknownpositionerror in Cp.
