Abstract: There are provided a steam valve and the like capable of preventing breakage of an auxiliary valve element and effectively suppressing the occurrence of a leak of steam in the auxiliary valve element. In the steam valve of an embodiment, the auxiliary valve element is structured to be in an open state in which the valve rod moves in an opening direction to increase a distance between an auxiliary-valve cap and a main valve element, thereby opening an auxiliary-valve steam introduction hole, and to be in a fully-closed state in which the valve rod moves in a closing direction in which the main valve element is closed to bring the auxiliary-valve cap and the main valve element into contact with each other, thereby closing the auxiliary-valve steam introduction holes. A contact position in which the auxiliary-valve cap and the main valve element are brought into contact with each other is located outside in a radial direction of the valve rod from the outer peripheral surface, of the auxiliary-valve tubular part, through which the auxiliary-valve steam introduction holes are formed.

Abstract: A device of a turbomachine actuates a setting device to vary a flow cross-section of a flow channel of the turbomachine passable by a fluid flow. The device includes a displacement mechanism having an adjustable actuation appliance and couplable with the setting device, and a drive device for displacing the actuation appliance. The displacement mechanism has a centrifugal force appliance displaceable between a basic position and a maximally displaced working position depending on a number of revolutions of the drive device, wherein the actuation appliance is displaceable depending on the position of the centrifugal force appliance with respect to the drive device. A reset device applies a force to the centrifugal force appliance by which the centrifugal force appliance is pressed in the direction of its basic position.

Abstract: An apparatus for extending the operational flow rate range of a turbine is described herein. Two or more removable sleeves may be used to change the cross-sectional area of a turbine. Each removable sleeve may define or eliminate the stator gap between a stator blade tip and an inner wall of the removable sleeve and a rotor gap between a rotor blade tip and an inner wall of the removable sleeve. A movable sleeve may be disposed in the turbine and may move between a first position and a second position in response to changes in the pressure differential across the turbine. The movable sleeve may define or eliminate a stator gap between a stator blade tip and the inner conical surface of the sleeve or a hub of the turbine and a rotor gap between a rotor blade tip and the inner conical surface of the sleeve.

Abstract: A system for actuating components of a gas turbine engine may generally include a turbine component incorporating a jamming device. The jamming device may include a bladder and a jammable media contained within the bladder. The jammable media may be jammable within the bladder from an unjammed state, wherein a fluid is contained within the bladder, to a jammed state, wherein the fluid is at least partially evacuated from the bladder. The system may also include a fluid coupling in fluid communication with the bladder. A portion of the turbine component may be located at a first position when the jammable media is in the unjammed state. Additionally, such portion of the turbine component may be located at a second position when the jammable media is in the jammed state.

Abstract: A hydraulic apparatus includes a first valve manifold that provides a shutdown capability and a second valve manifold that provides an overspeed control capability. The hydraulic apparatus advantageously further employs a hydraulic appliance that includes a check valve and a bypass apparatus. The hydraulic appliance enables the second valve manifold to additionally provide as an alternative function a redundant shutdown capability, thereby obviating the need to have three separate valve manifolds.

Abstract: Methods and systems are provided for a branch communication valve in a twin turbocharger system. A branch communication valve may be positioned adjacent to a dividing wall separating a first scroll and a second scroll of the twin turbocharger. In an open position, the branch communication valve increases fluid communication between the first scroll and the second scroll and in a closed position, the branch communication valve decreases fluid communication between the first scroll and the second scroll.

Abstract: An aircraft control structure for drag management includes a nozzle structure configured to exhaust a swirling fluid stream. A plurality of swirl vanes are positioned within the nozzle structure, and an actuation subsystem is configured to cause the plurality of swirl vanes to move from a deployed state to a non-deployed state. In the non-deployed state, the plurality of swirl vanes are substantially flush with the inner surface of the nozzle structure. In the deployed state, the plurality of swirl vanes produce the swirling fluid stream.
