摘要： A variety of refueling devices, systems and methods are disclosed for use in in-flight refueling. In one example one such device is towed by a tanker aircraft via a fuel hose at least during in-flight refueling, and has a boom member with a boom axis. The boom member enables fuel to be transferred from the fuel hose to a receiver aircraft along the boom axis during in-flight refueling. The device maintains a desired non-zero angular disposition between the boom axis and a forward direction at least when the refueling device is towed by the tanker aircraft in the forward direction via the fuel hose.

摘要： A situational awareness system for aerial refueling is disclosed. In embodiments, the situational awareness system may include one or more millimeter wave devices of a tanker aircraft configured to transmit one or more emitter signals toward an aircraft to be refueled, and receive one or more reflected signals reflected from the aircraft to be refueled. In embodiments, the situational awareness system further includes a controller communicatively coupled to the one or more millimeter wave devices and the display device, the controller configured to determine a distance between a refueling assembly of the tanker aircraft and the aircraft to be refueled based on the one or more reflected signals, and generate one or more control signals configured to cause a display substrate of a display device to display at least one of a metric or image indicative of the determined distance.

摘要： An automatic aircraft positioning system includes a first aircraft including one more fiducials, and a second aircraft including a positioning radar, control devices that are configured to control operation of the second aircraft, and a control unit in communication with the positioning radar and the control devices. The positioning radar is configured to transmit a radar transmit signal. The one or more fiducials are configured to receive the radar transmit signal and output one or more return signals in response to the radar transmit signal. The positioning radar is configured to receive the one or more return signals and determine a position and orientation of the second aircraft relative to the first aircraft, or vice versa, from the one or more return signals. The control unit is configured to automatically control the second aircraft in relation to the first aircraft during an automatic positioning mode.

摘要： A refuelling system is disclosed having a fuel conduit, a variable-position valve for controlling a rate of flow of fuel leaving the conduit, and a controller. The controller is configured to receive from a sensor arrangement a measurement of an electrostatic condition in a fuel tank being fuelled by the system. The controller is configured to control the variable-position valve to control the rate of flow of fuel based at least in part on the measurement received from the sensor arrangement.

摘要： An aircraft is provided and includes an airframe, an extending tail, a counter rotating, coaxial main rotor assembly including an upper rotor assembly and a lower rotor assembly, a translational thrust system positioned at the extending tail, the translational thrust system providing translational thrust to the airframe, at least one sensor and at least one inertial measurement unit (IMU) to sense current flight conditions of the aircraft, an interface to execute controls of a main rotor assembly in accordance with control commands and at least one flight control computer (FCC) to issue the control commands. The at least one FCC includes a central processing unit (CPU) and a memory having logic and executable instructions stored thereon, which, when executed, cause the CPU to issue the control commands based on the current flight conditions and a result of an execution of the logic for the current flight conditions.

摘要： A container may be supplied with an incompressible fluid. For example, the container may be partially or completely prefilled with the incompressible fluid. The container may be supplied with a flow of compressible gas via a first valve. The first valve may regulate the flow of the compressible gas supplied to the container based on a pressure setting of the first valve. A second valve may release the incompressible fluid from the container as the container is filled with the compressible gas and in response to a pressure of the container being greater than a pressure setting of the second valve. The pressure setting of the first valve may be greater than the pressure setting of the second valve.
