摘要： Embodiments of the invention relate to a system and method for controlling the size of gaps in a turbine engine. In many instances, it is desirable to minimize the size of the gaps between neighboring rotating and stationary components in a turbine engine, such as between a disc cover plate and a proximate pre-swirler. According to embodiments of the invention, each component can be provided with a sealing surface. The sealing surfaces can be angled relative to the axis of rotation. The sealing surfaces are spaced from each other so as to form a gap therebetween. The sealing surfaces may or may not be substantially parallel. As a result of such configuration, the size of the gap can be controlled by axial and radial movement of the components. For example, the gap between the cover plate and the pre-swirler can be adjusted by axially movement of the rotor.

摘要： A seal usable in a turbine engine for sealing a high pressure gas region from a low pressure gas region. The seal seals gaps between a rotatable body and a stationary body by creating forces opposing flow from the high pressure region to the low pressure region. During turbine engine operation, the seal creates aerodynamic forces that substantially prevents leakage of gases from a high pressure region to a low pressure region. The seal may be formed from a plurality of blades aligned in one or more rows and extending from a rotatable body towards a stationary body of the turbine engine to be in close proximity to the stationary body. The seal may also include a plurality of blades aligned in one or more rows and extending from the stationary body towards the rotatable body to be within close proximity of a surface of the rotatable body.
摘要翻译：一种用于涡轮发动机的密封件，用于从低压气体区域密封高压气体区域。密封件通过产生相对于从高压区域到低压区域的流动的力来密封可旋转体和固定体之间的间隙。在涡轮发动机运行期间，密封件产生空气动力，其基本上防止气体从高压区域泄漏到低压区域。密封件可以由多个叶片形成，多个叶片以一排或多排排列并且从可旋转体朝向涡轮发动机的固定体延伸，以便靠近固定体。密封件还可以包括多个叶片，其以一排或多排排列并且从固定体朝向可旋转体延伸，以便与可旋转体的表面紧密接近。
