Mach number distributions were deduced from the measurements of Pitot pressures, the stagnation pressure P(sub 0), and the stagnation temperature. Pitot pressures were measured by a Pitot rake equipped with 91 ports, a remotely controlled traverse system, and ESP (Electronically Scanned Pressure) system. From the Mach number distribution, the uniform core was defined as 0.60 m in diameter and 0.80 m in length. Average Mach numbers for P(sub 0) = 1, 2.5, 4, and 6 MPa were 9.45-9.68. Estimated uncertainties in the Mach numbers of the uniform core region were +/-
