Paper Abstract

A new technique on high speed imaging using an image converter camera for observing self destruction mechanism of gas turbine blade made of fine ceramic is discussed. The ceramic gas turbine blade is rotated by hot combustion gas flow at around 1,300 degree centigrade. The object is illuminated by hot gas circumstance and burst out unexpectedly in its spinning around 120,000 to 130,000 rpm. Ultranac, an image converter high speed camera, is used in this application in order to catch the event at 100,000 pictures per second (10 micro second's interval). As ceramic radiates some amount of light flux at the time of destruction, a new type of photo detecting system is applied to catch the moment of early stage of the destruction.
