Abstract:
A method and an on-board system for detecting impact on an impeller wheel of an aircraft engine. Deflection signals representative of the deflections on the blades of the impeller wheel are acquired. Each of the deflection signals is correlated with a pulse signal typical of an impact on a sound blade at the rotation frequency of the engine, in order to identify impacts on the impeller wheel. The impact signals are extracted from among the deflection signals. The impact signals are transmitted to the ground in order that the signals are analysed to detect defects on the blades of the impeller wheel.
Abstract:
The present description relates to a remote connection system suitable for being incorporated in an aircraft (1A, 1B, 1C) comprising at least one engine propeller (50A, 50B, 50C) having a plurality of blades (52A, 52B, 52C) suitable for rotating relative to a stationary module (10A, 10B, 10C) of the aircraft about an engine axis (X). The remote connection system comprises: a light emitter device configured, when the remote connection system is incorporated in the aircraft (1A, 1B, 1C), to emit a light beam that emerges to the outside of the propeller (50A, 50B, 50C), from at least one emission surface (54A, 54B, 54C) of said propeller (50A, 50B, 50C).
Abstract:
A method of balancing a turbine engine rotor, the method including mounting screws forming balance weights on the rotor in order to form a balance configuration, each screw possessing a predetermined weight and a screw head having a visual characteristic previously associated with its weight. A rotor balanced by such a method is also disclosed.
