Abstract
The invention relates to a method for measuring the kinematics of at least one rotor of an engine (14), especially a turbomachine, characterised in that the measurement is performed by gamma ray scintigraphy, the method comprising steps consisting in providing the rotor with radioactive tracers, and, during the operation of the engine, detecting the gamma rays emitted by said tracers by means of at least two gamma cameras (30).
Claims12
Method for measuring the kinematics of at least one rotor of an engine, wherein the measurement is carried out by scintigraphy using gamma radiation, the method comprising:
- a) equipping the rotor with radioactive tracers, and
- b) during the operation of the engine, detecting the gamma radiation emitted by said tracers by at least two gamma cameras which are oriented substantially at 90° to one another.
