Abstract
» . . This paper describes the application of a high temperature enamel coating to part of the surface area of the stator vanes of a jet engine, to increase the damping and* thereby reduce aerodynamically induced resonant vibration failures. The investigation showed that such a coating can increase the damping level by a very significant amount, particularly when it is initially very low as when the blades are stalled, for example. The use of enamel coatings is a relatively new approach to resolving jet engine vibration problems, and many engineering problems have to be overcome before all high temperature vibrations are controllable. Some of the engineering problems are discussed.
