FIXING AND SEALING RING REFLECTORS Russian patent published in 2017 - IPC F01D25/14 F01D25/12 

FIELD: machine engineering.

SUBSTANCE: invention describes a turbine (100) comprising a supporting structural element (101) which extends along the circumferential direction (102) of the turbine (100). The supporting structural element (101) has a groove (103) through which cooling air can be directed. The groove (103) extends along the circumferential direction (102). The turbine (100) comprises the first ring reflector (110) having a plurality of the first cooling holes and the second ring reflector (120) having a plurality of the second cooling holes. The first ring reflector (110) and the second ring reflector (120) are installed one after another along the circumferential direction (102) relative to the groove (103) so that the groove (103) is closed by the first ring reflector (110) and the second ring reflector (120). The first ring connector (130) is located between the first ring reflector (110) and the second ring reflector (120) so that the groove (103) is closed by the first ring connector (130) between the first ring reflector (110) and the second ring reflector (120). The first ring connector (130) forms a sliding contact with the second ring reflector (120).

EFFECT: reduced losses of cooling air during thermal expansion of gas turbine components.
