ABSTRACT:
A device is provided for passing a fluid flow across a static or rotating barrier wherein there is relative rotation between the flow and the barrier and wherein it is necessary to pass the maximum of flow through the device while keeping the diameter of the device as small as possible.
One embodiment of the invention shown in FIG. 2 is a device for use in a gas turbine engine for supplying cooling air across a bolted joint 19 to a space behind a cover plate 6 for cooling an engine disc. The device comprises a cylindrical receiver 11 having helical slots 13 running through it from one axial end face to the other the helix angle being the same as the angle of the relative velocity vector between the flow and the slots.
The helical shape of the slots ensures that the radius of the axis of each slot is constant along the length of the slots and allow greater slot height and hence greater flow area.
