Estimation of Critical Speeds of Airfoils and Streamline Bodies (open access)

Estimation of Critical Speeds of Airfoils and Streamline Bodies

Report presenting methods and charts for estimating the critical compressibility speeds of a large number of airfoils and streamline bodies. The systematic effects of thickness, thickness distribution, camber, camber location, leading-edge radius, and lift coefficient are considered. The results indicate that with a given lift coefficient, the thickness of the airfoil or of the body is the primary factor controlling its critical speed.
