The NACA High-Speed Motion-Picture Camera Optical Compensation at 40,000 Photographs Per Second,
Abstract
The principle of operation of the NACA high-speed camera is completely explained. This camera, operating at the rate of 40,000 photographs per second, took the photographs presented in numerous NACA reports concerning combustion, preignition, and knock in the spark-ignition engine. Many design details are presented and discussed, but details of an entirely conventional nature are omitted. The inherent aberrations of the camera are discussed and partly evaluated. The focal-plane-shutter effect of the camera is explained. Photographs of the camera are presented. Some high-speed motion pictures of familiar objects - photoflash bulb, firecrackers, camera shutter - are reproduced as an illustration of the quality of the photographs taken by the camera. (AN)
