    摘要: A system and method of generating a landing trajectory for use in landing an aircraft onto a deck of a waterborne ship includes sensing motion of the ship, and sensing wind speed and wind direction. The sensed motion of the ship is processed to generate estimates of ship attitude and vertical speed, and the sensed wind speed and wind direction are processed to generate estimates of air-wake disturbances ahead of the aircraft. The landing trajectory is generated based on the estimates of ship attitude and vertical speed and the estimates of air-wake disturbances. The system and method implement model predictive control to calculate the control maneuvers multiple steps ahead, which provides the capability to smoothly control the timing of the aircraft touchdown phase.

    摘要: A weight and center-of-gravity profile for an aircraft is determined prior to flight. An uncertainty band is determined for each of a plurality of points along a fuel vector for the planned flight. Each of the points along the fuel vector is compared to a predetermined flight limit (e.g., an FAA certified envelope). This comparison is used to decide whether the profile is suitable for flight of the aircraft. If so, an indication is provided to a user (e.g., on a display or by a text message) that the profile is suitable and the aircraft is ready for flight.

    摘要: The measured rolling rate of a ship and a measured liquid level difference in a liquid contained in a stabilizing tank are supplied to frequency dependent members having identical frequency response to obtain a derived roll angle and derived level difference after which a circuit is provided to measure the phase difference between the quantities developed and to develop an output analog voltage representing the difference between a desired relationship between the phases of the two and the actual phase relationship.
