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. 2. The air modulating system of claim 1, wherein the linkage element is removably fastened to the actuated mount. 3. The air modulating system of claim 1, wherein the floating plate further comprises a receptacle for slidably receiving the mounting flange of the linkage element. 4. The air modulating system of claim 3, wherein the receptacle is substantially the same cross-sectional shape as the mounting flange. 5. The air modulating system of claim 3, wherein the receptacle extends through a thickness of the floating plate such that it is open at both the first side and a second side opposite the first side. 6. The air modulating system of claim 5, wherein the thickness of the floating plate at the receptacle, comprising the distance from the first side to the second side, is greater than a thickness of the mounting flange. 7. The air modulating system of claim 1, wherein the floating plate is configured to pivot about the mounting flange. 8. The air modulating system of claim 1, wherein the floating plate further comprises a ledge on a second side of the floating plate opposite the first side, wherein the ledge extends from an outer perimeter of the second side of the floating plate and circumscribes the second side of the floating plate. 9. The air modulating system of claim 1, wherein the floating plate further comprises an opening, wherein the opening is substantially the same cross-sectional shape as the fluid passage inlet. 10. The air modulating system of claim 1, and further comprising a plurality of linkage elements, a plurality of circumferentially spaced floating plates, and a plurality of circumferentially spaced fluid passage inlets. 11. The air modulating system of claim 10, wherein the actuated mount comprises a sync ring configured to move the plurality of floating plates circumferentially and wherein the plurality of floating plates abut the plurality of fluid passage inlets to restrict fluid flow into the fluid passage inlets. 12. The air modulating system of claim 1, and further comprising: a fixed member, wherein the floating plate is retained in a space between the fixed plate and the fixed member. 13. The air modulating system of claim 2, wherein the linkage element comprises a material of lower hardness value than materials comprising the actuated mount and floating plate. 14. An actuated mount assembly for positioning a floating plate over a fluid passage of a heat exchanger of a gas turbine engine, the actuated mount assembly 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 plates 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, and wherein the linkage element is removably fastened to the actuated mount. 15. The actuated mount assembly of claim 14, wherein the floating plate further comprises an opening substantially matching the cross-sectional shape of the fluid passage inlet, and wherein the fluid passage inlet and the opening of the floating plate align to allow fluid to move into the fluid passage of the heat exchanger. 16. The actuated mount assembly of claim 14, wherein the floating plate comprises a receptacle for receiving the mounting flange of the linkage element, and wherein the receptacle extends through a thickness of the floating plate such that the receptacle is open at both the first side and a second side opposite the first side and the receptacle is substantially the same cross-sectional shape as the mounting flange. 17. The actuated mount assembly of claim 14, wherein the floating plate further comprises a ledge on a second side of the floating plate opposite the first side, wherein the ledge extends from an outer perimeter of the second side of the floating plate and circumscribes the second side of the floating plate. 18. The actuated mount assembly of claim 14, further comprising a plurality of linkage elements, a plurality of circumferentially spaced floating plates, and a plurality of circumferentially spaced fluid passage inlets. 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; andtranslating 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. 20. The method of claim 19, further comprising inserting a linkage element into a receptacle of the floating plate such that the floating plate is slidably engaged with the linkage element.
