Title:
タービンエンジンの冷却空気を管理するための装置
Document Type and Number:
Japanese Patent JP5698461
Kind Code:
B2
Abstract:
An exemplary embodiment of the invention is directed to a turbine engine (10) having a rotatable turbine rotor assembly (58), a stationary nozzle assembly (52) disposed adjacent thereto and a wheel space (74) defined therebetween. The wheel space (74) receives cooling air (80) therein and includes a sealing feature (96) located on the first, rotatable turbine rotor assembly (58) and extending axially into the wheel space (74) and a sealing land assembly (110) having a sealing land (102) associated with a moveable member (114) installed in an opening (112) in the second, stationary nozzle assembly (52). A biasing member (124) constructed of shape memory alloy is associated with the moveable member (114) and operates to bias the moveable member, and associated sealing land (102), axially into the wheel space (74) towards the sealing feature (96) as the turbine engine (10) transitions from a cold state to a hot state to reduce the release of cooling air (80) from within the wheel space (74).
