Sensors to maintain helicopters

A technological network for the real-time monitoring of the aircraft

The maintenance of helicopters can be improved thanks to modern systems that allow to keep constantly under control the State of health of the aircraft, allowing technical operators to make accurate checks, without opening the rotary-wing aircraft. It is possible thanks to a network of sensors installed on board, which synchronize the data coming from the operating parameters of the aircraft and the engine, in order to understand when and how damages to components occur.

This is also what the Health and Usage Monitoring System (Hums), developed by the US company Collins Aerospace, can do. The network of sensors allows the identification of damaged parts and assesses the speed at which the problem is progressing, giving the possibility to intervene before the failure reaches a critical level.

With this type of system it is possible to plan maintenance in the best way and in a short time: leaving the aircraft stationary for the time strictly necessary for the intervention. The data allows the real-time detection of cracks, misalignments or imbalances. It means greater safety of the flight and the people on board. An approach that also aims to prolong the life of the helicopter.
