Deformable propeller blade and shroud |
摘要 |
A propeller blade fabricated from composite material having a plurality of upper layers, each upper layer being flexible and having fibers oriented in a first direction. The material further includes a plurality of lower layers, each lower layer being flexible and having fibers oriented in a second direction which is different than the first direction of the fibers of the upper layers. A flexible layer of resistive heating material is disposed between the upper and lower layers. A control and power supply are provided for controlling the amount of electricity delivered to the layer of resistive heating material. The composite material changes its shape upon changing the temperature of the layer of resistive heating material by manipulating the controller.
