The Pitot probe with 5-hole pyramidal head originally developed by NAL was planed to be adopted in the early phase of the development of the High-Speed Flight Demonstration Phase II. But it was turned out that the probe could not achieve enough ability of Mach number measurement at high altitude condition. To improve the ability of the ADS, pressure holes were added on the aft surface of the probe. As the result, the error of Mach number measurement due to the errors of pressure sensors became 2.7% of an original error at best condition, and the new probe could achieve adequate accuracy of Mach number.
