Abstract
Multistage brush seals are made by initially specifying designs thereof for collectively sharing a differential pressure along an adjacent land subject to relative rotation with the seals. The seals are modified to share the loading without blowdown therefrom. The seals are further modified to ensure rotational stability with the land. The seals are built and tested under pressure to determine pressure blowdown thereof. And then, the seals are again modified to share the pressure loading under blowdown. In this way, the seals share the load in situ under the effects of blowdown.
