✦ Synopsis

of anti-rotation devices linked to the seal housing.

The static sealing between the side of each carbon segment and the seal housing allows sufficient radial movement to accommodate shaft radial excursions.

The endurance cycle and wear results are shown in Figure 13. The air leakage of approximately 3.5 g/s is higher than on the axial carbon seal, about 0.5 g/s, but lower than the labyrinth seal where it is approximately 50 g/s. The wear on the radial carbon is 25 microns, compared with about 2 microns on the axial carbon.

Seal technology comparisons

Techspace Aero and Burgmann have used the seal technology comparisons shown in Table 3 to justify the selection of the lift augmentation carbon seal.
