Abstract
A blade made of a composite material for an aircraft turbomachine fan, the blade comprising means for measuring internal deformations of the blade and means for remotely storing and transmitting signals for measuring the deformation of the blade, which means are connected to the measuring means, the measuring means and the remote storage and transmission means being located in the composite material. The means for measuring can be configured to supply the means for remotely storing and transmitting.
Claims13
A blade for an aircraft turbomachine fan, the blade being made of a composite material, the blade comprising:
- means for measuring internal deformations of the blade;
- and
- means for remotely storing and transmitting blade deformation measurement signals connected to means for measuring,
