1. A system for modulating air flow in a gas turbine engine, comprising:
a seal wall comprising an opening;
a seal door configured to sealably and slideably engage the seal wall;
an actuator configured to move the seal door over the opening, wherein the seal door is forward of the seal wall and is configured to press against the seal wall in response to a pressure differential between an aft side of the seal door and a forward side of the seal door in response to the seal door covering the opening;
a track under the seal door; and
a sync ring coupled to the seal door, wherein the seal door slides along the track in response to the sync ring rotating circumferentially.
