(Model te t , ind tunnel models H YPERSONIC WI D UNNELS, Pressure. The characteristics of a 40 degrees half-angle cone for e suring flow angularity wer determined peri entally. Tests were conducted at a Mach number of 21 in helium with check points at Mach nu b r 3.55 in air for angles of pitc up to 5 degrees. he air tests confirm d theoretical indic ions of small or egligible Mac numb r and st-mediu ffects for the c of air and helium. The instrument is capable of measuring flow angularity at high Reynolds numbers nd peeds great r t an that necessary for hock attachment to within + or - 1/3- egrees. (Author)
