摘要： A fuel system for a turbine engine is provided. The fuel system includes a positive displacement pump driven by an electric motor. The pump is rotated in a first direction to deliver fuel to the turbine engine, and a second direction for evacuating fuel from the turbine engine. A shut-off check valve is open in a first direction in response to a first differential pressure created by the pump in the first direction. The shut-off check valve is biased to a closed position when the pump is rotating in the second direction. An ecology check valve is biased to a closed position in the first direction and open in the second direction in response to a second differential pressure created by the pump. The check valves open and close automatically in response to the pressures generated by the positive displacement pump in each of the first and second rotational directions. In this manner, simple, reliable valves are utilized to regulate the flow of fuel in the fuel system.

摘要： An integrated skid system integrates the functions of multiple skids into a single skid to reduce the skid footprint and the complexity of the overall system. A multi-motor controller monitors the devices on the integrated skid to maintain proper temperature, pressure and current draw in the devices. Base on this information, the multi-motor controller can make decisions on faults and fault accommodation and communicate with a main controller regarding the operating states of the skid devices via a single serial or Ethernet-type connection.

摘要： Oil system components for a turbine engine are used to provide a vacuum system for a fuel stabilization unit (FSU). A vacuum system pulls oxygen and other contaminants from fuel into a vacuum chamber within the FSU. The vacuum system pumps the discharge through a vacuum outlet in the FSU toward a vacuum pump. Due to the quality of vacuum required, a two-stage vacuum pump is used. A first stage vacuum pump is an oil system scavenge pump for the turbine engine and the second stage vacuum is provided by a second stage vacuum pump. The discharge flows from the vacuum chamber through to the second stage vacuum pump and is then added to the oil supply. The oil and discharge mixture is sent through an oil system de-oiler and a de-aerator to clean the oil supply prior to pumping the oil back through the oil system.

摘要： A turbine engine inspection arrangement utilizes a motor that is otherwise utilized for starting the engine. An inspection interface allows for communicating with a motor controller to operate the motor in an inspection mode. During inspection, the motor moves the components of the engine very slowly or in an incremental fashion to facilitate visual inspection of the engine components, such as the turbine blades.

摘要： A fluid scavenging system is provided for a lubrication system including a gas turbine engine having bearing compartments. A valve includes a housing with an outlet and a plurality of fluid inlets respectively in fluid communication with the bearing compartments. The valve includes a rotationally driven member arranged within the housing with the member having a plurality of ports arranged thereon each defining an arcuate slot. Each of the ports are selectively in fluid communication with one of the fluid inlets through the arcuate slot during rotation of the member for selectively permitting fluid flow between the opening of one of the fluid inlets through one of the corresponding ports in the member. A fluid pump is fluidly connected to the outlet for drawing fluid from each of the plurality of fluid compartments during fluid rotation of the member. The driven member rotates about an axis 360°, and preferably, the ports are respectively aligned with the fluid inlets for approximately at least 360° such that the pump does not run dry. The arcuate slots may overlap during a range of degrees such that more than one compartment is scavenged. The size of the arcuate slot and degrees through which the arcuate slot is in communication with its respective inlet determines the duration that a particular bearing compartment is scavenged and the volume of bearing fluid that may be removed from the compartment.

摘要： A fuel supply control system for a gas turbine includes a plurality of solenoid valves. The solenoid valves are energized in a timing sequence with a phase relationship designed to achieve a desired fuel flow. In one example, one solenoid valve is associated with a primary portion of a fuel manifold while at least two other solenoids are associated with a secondary portion of the manifold. A controller that energizes the solenoids to achieve the desired fuel flow can receive feedback information regarding turbine performance to make adjustments to the solenoid operation to bring the turbine performance closer to a desired level.
