ENGINE HEALTH MONITORING

摘要

A vehicle is provided that has a rigid dressing raft 200. The rigid dressing raft 200 provides a part of a fluid and/or electrical system to the vehicle. The rigid dressing raft comprises elongate fibres 232, which may provide strength to the raft. The fibres 232 are electrically conductive, and a voltage source may be applied to at least one of the fibres. The fibre 232 may form a part of an electrical measurement circuit 400, such as a wheatstone bridge, which may be used to determine the electrical resistance of the fibre 232. The electrical resistance of the fibre 232 may then be used to determine the temperature to and/or stress/strain of the raft 200.

主权项

1. A rigid dressing raft for a vehicle, comprising:
a rigid material; at least a part of a component or system of the vehicle provided to the rigid material; and at least one electrically conductive elongate fibre element that is integral to the rigid dressing raft, wherein: the electrically conductive elongate fibre element is connectable to an electrical measurement circuit, such that, in use: the electrical measurement circuit supplies an electrical current to the elongate fibre element, thereby allowing the resistance of the elongate fibre element to be determined, the determined electrical resistance being representative of at least one property of the rigid dressing raft.
