註釋Numerical results are presented in the form of charts which permit the rapid estimation of the deviations from free-stream values of static pressure, angle of attack, and angle of sideslip so that suitable positions for orifices and vanes for measuring these quantities can readily be selected. Comparisons between calculated values and those measured at Mach number of 0.21 for a body fineness ratio 6 show that for distances greater than 1/2 body diameter in front of the body nose and for angles of attack less than 20 degrees the approximate theory used herein is adequate for predicting the best location for static-pressyre and angle-measuring pickups.
