1. An air modulating system for a gas turbine engine, the air modulating system comprising:
- a fixed plate comprising a fluid passage inlet;
a floating plate with a first side, wherein the first side is adjacent to the fluid passage inlet;
an actuated mount configured to move the floating plate relative to the fixed plate, wherein the floating plate is moved circumferentially about an axis; and
a linkage element for connecting the floating plate to the actuated mount, wherein the linkage element comprises a mounting flange configured to slidably engage the floating plate and allow the floating plate to translate along the axis to contact the fixed plate in response to a variable fluid pressure load on the second side of the floating plate.

19. A method of modulating fluid flow to a fluid passage inlet of a gas turbine engine, the method comprising the steps of:
-
rotating a mount circumferentially to guide a floating plate circumferentially about an axis and thereby across the fluid passage inlet, wherein the floating plate includes a first side with a body portion and a second side opposite the first side, and wherein the passage inlet is closed when the passage inlet is covered by the body portion of the first side of the floating plate; creating a variable pressure load to act on the second side of the floating plate; and translating the floating plate along the axis as a function of the variable pressure load, wherein translating the floating plate along the axis causes the first side to contact a surface forming the passage inlet. - View Dependent Claims (20)
