Heat-Transfer and Pressure Tests on an Oblate Elliptic Nosetip in the NSWC/WO Hypersonic Tunnel at Mach Number 5 (WTR-1346).
Abstract
An extensive data base on a 2:1 elliptical nosetip shape to be utilized for verification of the AVCO MTSCT three-dimensional transition code was generated in the NSWC Hypersonic Tunnel at Mach Number 5. Four nosetip models in which the surface roughness was varied from a smooth wall to a roughness value of 10 mils were tested. The first three nosetips were instrumented with 112 backfaced chromel-alumel thermocouples. The fourth model (i.e., 10-mil roughness) instrumentation consisted of 67 thermocouples and 31 Statham pressure transducers. The test matrix consisted of sixty runs where the variables included angle-of-attack, tunnel Reynolds number, and wall enthalpy ratio. (Author)
