文摘

Prediction techniques for crossflow waves are studied on an elliptic cone at Mach 6. Growth rate is sensitive to analysis technique, wave angle and phase speed are not. Wave properties computed using LASTRAC are validated against test data. Traditional stability analysis techniques are compared to Spatial BiGlobal analysis. Surface marching PSE is in excellent agreement with Spatial BiGlobal and costs less.
