摘要： Divergent flaps of an axisymmetric exhaust nozzle include a hot inner gas path wall spaced from an outer wall to define a cooling fluid channel therebetween along the length of the flap from the upstream end of the flap near the divergent nozzle throat to near the downstream end of the flap. A slot or other opening in the flap inner wall at or just downstream of the nozzle throat communicates with the upstream end of the channel. Openings in the flap outer wall near the downstream end of the flap provide communication between the channel and external ambient air at a higher pressure than the gas at the nozzle throat. Ambient air thus travels upstream through the channel, convectively cooling the hot inner wall and exits through the slot in the inner wall at or near the throat to film cool the gas path side of the inner wall.

摘要： A turbine airfoil includes a leading edge having a concave cooling flow passage. An apex of the concave cooling flow passage divides the flow passage into adjacent regions. The turbine airfoil includes a first plurality of turbulators disposed in one of the adjacent regions, and a second plurality of turbulators disposed in the other of the adjacent regions. The first and second pluralities of turbulators are positioned relative to one another to divert cooling flow in opposing swirl streams that recombine along the apex and to effect a desired heat transfer and pressure loss.

摘要： The guide-vane system (5) serves to change the position of the guide vanes (6) of an axial-flow exhaust-gas turbine of a turbocharger. The guide vanes (6) are arranged axially symmetrically to the turbine axis (1) in a flow passage (14) carrying exhaust gas (15) and can be pivoted by a pivoting device in each case about a radially directed axis (8). A vane shank (18) led radially outward from the flow passage (14) through a casing wall is attached to each of the guide vanes (6). With its part directed outward, the vane shank (18) is mounted so as to be rotatable about the pivot axis (8). The pivoting device contains an adjusting ring (19), arranged outside the flow passage (14) and rotatable about the turbine axis (1), and also an adjusting lever (20) which transmits a torque from the adjusting ring (19) to the vane shank (18) of each guide vane (6). The adjusting ring (19) is mounted with its outside on rolling elements which are each designed as one-armed levers (27) and are mounted so as to be pivotable on a component of a casing wall, this component being designed as a supporting ring (16). This guide-vane system is characterized by high reliability even under heavy operating conditions.
