| 摘要 | An example seal shaft includes a cylindrical body establishing a bore that extends axially between a first end portion of the body and a second end portion of the body. Apertures are also established in the body. The apertures extend radially between an outer surface of the body and the bore. The seal shaft further includes a first group knife edge seals and a second group of knife edge seals. The first group of knife edge seals have a diameter, and a ratio of the diameter to the total cross-sectional area of the apertures is between 58.79 and 78.77. | ||
