MOTION ANALYSIS by Means of HIGH-SPEED PHOTOGRAPHY 440148
IN analyzing the operation of aircraft-engine parts, the high-speed motion picture camera has many advantages over the older methods, which involved the use of vibration indicators, stroboscopes, and strain gages.
High-speed motion picture studies have the advantages of forming a permanent record and of accurately evaluating transient conditions.
Many subjects have been studied by means of high-speed motion pictures, some of which are here shown and discussed by Mr. Jackes.
