Contactless Measurement of the Tip Clearance in a Jet Engine Turbine,

Abstract

A description of a new method of contactless measurement of the tip clearance in a jet engine turbine, based on the properties of radioactive isotopies is shown. This method makes it possible to determine tip clearance in a jet engine during operaiton, making it possible to determine clearance changes at various times between overhauls. This method is also useful for measuring radial clearance between any rotating element and its housing. (Author)
