采用热相变致动的起落架上位锁机构
摘要：
一种用于保持和释放起落架系统的上位锁组件，所述上位锁组件包括：热致动器，热致动器包括设置用以在其中容纳可膨胀材料的腔；耦合到所述腔用于加热所述可膨胀材料并且引起其体积膨胀的加热机构；可滑动地耦合到所述腔并且适于响应于所述体积膨胀而伸出的活塞；和上位锁释放机构，所述上位锁释放机构在所述活塞伸出时可释放地与所述活塞接合，使得所述接合的上位锁释放机构引起所述起落架的释放。
摘要（英）：

An uplock assembly for retaining and releasing landing gear systems, said uplock assembly comprising: a thermal actuator comprising: a chamber configured to contain expansible material therein; a heating mechanism coupled to said chamber for heating said expansible material and causing volumetric expansion thereof; a piston slidably coupled to said chamber and adapted to extend in response to said volumetric expansion; and an uplock release mechanism releasably engaged by said piston when extended such that said engaged uplock release mechanism causes the release of said landing gear.
