摘要:
Systems and methods are disclosed herein for distributing cooling air in gas turbine engines (100). A tangential on board injector ("TOBI") (220) may supply cooling air to a turbine section (190, 191) of a gas turbine engine (100). The cooling air may be split into a first cooling air path and a second cooling air path. The first cooling air path may fluidly connect the TOBI (220) and the interior of a first stage rotor blade (264). The second cooling air path may fluidly connect the TOBI (220) and a cavity (C1). The cavity (C1) may be located between a first disk (268) and a second disk (270). The cooling air paths from a single cooling air source may thermally isolate portions of the turbine section (190, 191).

An apparatus for a gas turbine engine includes an airfoil (22) defining a leading edge (28) and a trailing edge (30), a root (26) located adjacent to the airfoil (22), a vapor cooling system, and a film cooling system for cooling the airfoil in conjunction with the vapor cooling system. The vapor cooling system includes a vaporization section (36) located within the airfoil (22) and a condenser (40) section located within the root (26).
摘要:
A cooling system for gas turbine engines (100) includes a turbine rotor compartment (106) defining a cooling air plenum (120). A plurality of turbine discs (130,132) are rotatably housed within the rotor compartment (106). A cooling air inlet (122) is in fluid communication with the plenum (120). Each turbine disc includes a cooling outlet (138) in fluid communication with the plenum for cooling the rotor compartment.

摘要:
A hybrid cooling system for a gas turbine engine (10) includes a vapor cooling assembly (26) and a cooling air cooling assembly (16). The cooling air cooling assembly (16) is configured to remove thermal energy from cooling air used to cool a first component (12) of the gas turbine engine (10). The vapor cooling assembly (26) configured to transport thermal energy from a vaporization section (52) to a condenser section (54) through cyclical evaporation and condensation of a working medium sealed within the vapor cooling assembly (26). The vaporization section (52) is located at least partially within a second component (14) of the gas turbine engine, and the condenser section (54) is located outside the second component (14).
