Abstract

A cooling arrangement (70) for a gas turbine engine according to an example of the present disclosure includes, among other things, an offtake duct (78) that has an offtake inlet (80) coupled to a cooling source, the offtake duct (78) defining a throat (82), and a valve (72) downstream of the throat (82). The valve (72) couples the offtake duct (78) and a first cooling flow path. The valve (72) is operable to selectively modulate flow through the offtake duct (78). A bleed passage (86) includes a bleed inlet (88) coupling the offtake duct (78) and a second cooling flow path. The bleed inlet (88) is defined at a location between the offtake inlet (80) and the throat (82), inclusive.
