FIELD: aircraft engine manufacturing.
SUBSTANCE: invention relates to devices used to support turbine of gas-turbine engines of flying vehicles. Proposed support of turbine of gas-turbine engine has turbine housing 1, bearing housing 2 and bracing rods 3 connecting housings 1 and 2. Rods 3 pass through inner spaces of nozzle blades 4. One rod or pair of bracing rods 3 can pass through inner space of one nozzle blade. Longitudinal axes 5 of bracing rods are tilter relative to cross section of support, axes 5 in each pair of adjacent rods being tilted in different directions. Thanks to such tilting, rods 3 in each pair either form or intersect in plane. Flexible members 6 are installed on rods 3. Invention improves reliability of supports of gas-turbine engines owing to taking up axial loads, appearing on engine at changes of aircraft altitudes, by support members and elimination of temperature stresses on support members.
EFFECT: improved reliability of turbine rotor supports.
