摘要： Fail-fixed hydraulic actuator systems for aircraft include a hydraulic actuator having a piston in a housing. The piston separates the housing into a retract cavity and an extend cavity. A sleeve is moveably arranged within the housing and includes a sleeve aperture that is aligned with a piston head during normal operation. A driving mechanism is configured to drive movement of the sleeve to maintain alignment between the sleeve aperture and the piston head. A low pressure cavity is defined between an interior surface of the housing and the sleeve and, when the piston head is offset from the sleeve aperture, the low pressure cavity is hydraulically connected to one of the retract cavity or the extend cavity to cause a pressure differential with the other of the extend cavity and the retract cavity and cause movement of the piston head to align with the sleeve aperture.

摘要： A pumping system includes a first variable displacement pump having a first inlet and a first outlet. The first outlet is fluidically connected to a system outlet. A first actuator is mechanically coupled to a first displacement mechanism of the first variable displacement pump A second variable displacement pump includes a second inlet and a second outlet. The second outlet is fluidically connected to the system outlet. The pumping system also includes a second actuator mechanically coupled to a second displacement mechanism of the second variable displacement pump. An electrohydraulic servo valve is hydraulically connected to the first and second actuators. An electronic engine controller is in communication with the electrohydraulic servo valve and is configured to send electrical current to the electrohydraulic servo valve to drive the first actuator and the second actuator.

摘要： A fuel metering system includes a pump with an inlet and an outlet, a first flow path including a first valve fluidically connected to the outlet of the pump, and a second flow path including a second valve fluidically connected to the outlet of the pump, a third valve, and a fourth valve. An electrohydraulic servo valve in a first position hydraulically connects the inlet of the pump to the first, third, and fourth valves to close the first valve, open the third valve, open a first window of the fourth valve, and close a second window of the fourth valve. The electrohydraulic servo valve in a second position hydraulically connects the outlet of the pump to the first, third, and fourth valves to open the first valve, close the third valve, close the first window of the fourth valve, and open the second window of the fourth valve.

摘要： A fuel supply system for a gas turbine engine has a fuel tank, a main fuel pump for receiving fuel from the fuel tank, and an electric pump also for receiving fuel from the fuel tank. The main fuel pump and the electric pump both deliver fuel to a sharing valve. The sharing valve selectively delivers fuel downstream into a gas generator portion of the gas turbine engine and to an augmentor. A control is programmed to control the sharing valve, such that fuel flows from the main fuel pump to the augmentor, and to the gas generator at higher demand operation, and does not flow from the main fuel pump at lower demand operation. A gas turbine engine and a method are also disclosed.

摘要： A fuel delivery system includes a turbine, a pump, and an oxygen removal unit. The turbine is adapted to receive and expel fuel at different pressures. The pump is in fluid communication with, and mechanically coupled to, the turbine, and is configured to expel and receive the fuel at about the respective different pressures. The turbine is configured to convert pressure energy of the fuel to kinetic energy to drive the pump. The oxygen removal unit is in fluid communication with at least one of the turbine and the pump, and is configured to remove oxygen from the fuel.

摘要： Actuator systems and methods of operation are disclosed. The systems include a hydraulic actuator having a primary piston having a piston head arranged within a housing defining retract and extend chambers on opposite sides of the piston head. A control element is configured to control a supply of pressure to each of the retract and extend chambers. An actuator valve is coupled to the housing and includes a secondary piston that is biased into the retract chamber in an open flow state and when the primary piston is in a fully retracted state the piston head urges the secondary piston into a closed flow state. The actuator valve defines a flow chamber where, in an open flow state, fluid can be passed through the flow chamber and in a closed flow state the fluid is prevented from passing through the flow chamber.
