System and method for measuring a clearance between a rotary vane and a casing of a turbine engine

A measurement system for measuring a clearance between a rotating blade and a casing of a turbomachine, the measurement system comprising:

• a removable fastening device shaped to adapt, in a form-fitting manner, to a complementary location of the casing in a mounted position, the removable fastening device being provided with a locking mechanism to maintain the mounted position of the measurement system on the casing,
• a retractable stop mechanism provided with a guide and a finger configured to be arranged relative to the guide in a deployed position in which the finger is configured to hold the rotating blade in a measurement position,
• a remote acquisition device configured to measure at least one clearance between the rotating blade and the casing when the removable fastening device is in the mounted position and the retractable stop mechanism is in the deployed position, and
• a plate to which the removable fastening device, the retractable stop mechanism and the remote acquisition device are attached.
