FIELD: mechanical engineering; high-temperature gas-turbine engines.
SUBSTANCE: according to invention, inner housing of support is made in form of three-layer envelope which forms, in addition to oil space, cooling air ring space enclosing oil space, also discharge air ring space. Load-bearing posts are rigidly connected with all three layers of inner housing envelope. Spaces of posts communicate with cooling air space and, through metering holes, with space formed between fairing, outer housing and inner housing with load-bearing posts. Pre-oil spaces communicate with discharge air ring space. Fairing consists of sectors installed for free thermal expansion.
EFFECT: increased strength reliability of support by excluding deformation processes in structural members.
