Abstract
1. Опора роторов турбин ВД и НД высокотемпературного ГТД, интегрированная с сопловым аппаратом ТНД, включающая в себя: наружный корпус, внутренний корпус с газовоздушными уплотнениями, полые лопатки соплового аппарата ТНД, объединенные в блоки и закрепленные своими кольцевыми выступами на периферийных полках в соответствующих кольцевых пазах наружного корпуса с фиксацией в осевом и окружном направлениях, а кольцевыми выступами на внутренних полках - в кольцевых пазах внутреннего корпуса с фиксацией их в окружном направлении, и корпус подшипников роторов турбин ВД и НД с уплотнениями масляной полости, отличающаяся тем, что корпус подшипников роторов турбин ВД и НД с уплотнениями масляной полости размещен во внутреннем корпусе без механической связи с ним и крепится к наружному корпусу своими силовыми стойками, проходящими через полые лопатки соплового аппарата.2. Опора роторов турбин ВД и НД газотурбинного двигателя по п.1, отличающаяся тем, что часть полых лопаток соплового аппарата ТНД, предназначенных для прохода силовых стоек корпуса подшипников роторов турбин ВД и НД, выполнена с увеличенными по хорде и максимальной толщине профилями поперечного сечения.1. The support of the rotors of the VD and LP turbines of the high-temperature gas turbine engine integrated with the high pressure gas nozzle apparatus, including: the outer casing, the inner casing with gas-air seals, the hollow blades of the high pressure gas turbine nozzle, combined into blocks and fixed with their ring protrusions on the peripheral shelves in the respective annular the grooves of the outer casing with fixation in the axial and circumferential directions, and the annular protrusions on the inner shelves - in the annular grooves of the inner casing with fixing them in the circumferential direction, and the casing VD and ND turbine rotor bearings with oil cavity seals, characterized in that the VD and ND turbine rotor bearings with oil cavity seals are housed in the inner housing without mechanical connection with it and are attached to the outer housing by their power struts passing through the hollow blades of the nozzle apparatus .2. The support of the rotors of the VD and LP turbines of the gas turbine engine according to claim 1, characterized in that a part of the hollow blades of the nozzle apparatus of the TND intended for the passage of the power struts of the bearing housing of the rotors of the turbines of the VD and LP are made with cross-section profiles increased in chord and maximum thickness.
