Abstract
A gas turbine engine includes a first duct, a second duct, and a bladder. The bladder is disposed in the first duct and communicates with the second duct. A first gas flow is capable of passing through the first duct and a second gas flow is capable of passing through the second duct. The bladder is adapted to receive a bleed gas flow from the second duct and inflate within the first duct, thereby decreasing an area in the first duct through which the first gas flow is capable of traveling.
Claims4
A kit for a gas turbine engine comprising:
- a movable component;
- a bias element connected to the movable component;
- and
- a bladder configured to be connected to the movable component and adapted to receive a bleed air therein, wherein the bias element is adapted to exert a bias force on the movable component and the bladder, and wherein the bladder is permeable to allow a gas flow to pass through the bladder.
