摘要： A landing assembly and method of landing an aircraft. The landing assembly includes a landing gear, a charging circuit, a sampling circuit and a processor. The charging circuit applies a charge to the landing gear and the sampling circuit measures a discharge rate of the electrical charge from the landing gear. The processor determines a contact between the landing gear and a surface from the discharge rate.

摘要： According to one aspect, a method of initial rotor state compensation for a rotorcraft includes determining a vehicle attitude of the rotorcraft prior to takeoff of the rotorcraft. A rotor state compensation is computed based on the vehicle attitude. A plurality of rotor servos is commanded to an initial rotor state based on a nominal rotor neutral position value in combination with the rotor state compensation to establish a predetermined takeoff trajectory of the rotorcraft.

摘要： According to an aspect of the invention, a method of optimal safe landing area determination for an aircraft includes accessing a probabilistic safe landing area map that includes a plurality of probabilistic indicators of safe landing areas for the aircraft. A processing subsystem that includes one or more processing resources generates a list of candidate safe landing areas based on the probabilistic safe landing area map and one or more constraints. At least two of the candidate safe landing areas are provided to a path planner. The list of candidate safe landing areas is ranked based on results from the path planner indicating an estimated cost to reach each of the candidate safe landing areas. Based on the ranking, an indicator of an optimal safe landing area is output as a desired landing location for the aircraft.

摘要： A system and method for controlling a trajectory of a vehicle includes a crew seat with first and second inceptors mounted to a portion of the crew seat; a processor with memory having instructions stored thereon that cause the system to: receive signals indicative of a trajectory for the vehicle; receive signals indicative of a deviation in a trajectory of the vehicle; and transmit signals for controlling a flight path of the vehicle. A second inceptor is configured for selecting one or more menus on a user display and being configured to interact with a fly-by-wire control system for transmitting signals indicative of movement of flight surface of the vehicle. The crew seat is configured to be located on the vehicle, in a control station remotely located from the vehicle, or in a second vehicle remotely located from the vehicle.

摘要： A method of trajectory control for a vehicle includes obtaining an initial trajectory; presenting the initial trajectory as a current trajectory on an I/O device, the current trajectory presented overlaying terrain; initiating travel of the vehicle along the current trajectory; updating the current trajectory and the terrain in real time as the vehicle travels along the current trajectory; determining if change in the current trajectory is required; changing the current trajectory to an altered trajectory in response to determining change in the current trajectory is required; and presenting the altered trajectory on the I/O device, the altered trajectory presented overlaying the terrain.

摘要： A method of retrofitting a mechanically controlled aircraft with a fly-by-wire system includes removing a mechanical links between mechanical pilot inputs and actuators operable to drive flight surfaces. Electromechanical actuators are coupled between a plurality of vehicle management computers and the actuators. Each of the electromechanical actuators is operable to receive commands from the vehicle management computers and output a mechanical force to an input linkage of one of the actuators. Electromechanical pilot input modules are coupled to the mechanical pilot inputs. Each of the electromechanical pilot input modules is operable to convert a pilot-driven input force of an instance of the mechanical pilot inputs into an electronic signal indicative of the pilot-driven input force. At least one high performance computer is coupled to at least one of the vehicle management computers. The high performance computer executes one or more high level intelligence algorithms to selectively operate the aircraft autonomously.
