High-Speed Photography in Aerodynamic Research at the National Physical Laboratory

Abstract

A brief account is given of some of the applications of high-speed photography and optical methods of flow-visualization to recent work in the wind-tunnels and shock-tubes of the Aerodynamics Division of the National Physical Laboratory. The examples shown are a simulated boiler-tube experiment, an aileron-buzz experiment, colour-schlieren and polarization-interferometer photography of transonic flows, photography of direct luminosity of flows in shock-tubes, and a multiple-spark camera for shock-tube applications.
