20140290928 | Coordinated Flow Control - A method of coordinated flow control in a heat exchanger system includes adjusting a position of a variable actuator of the heat exchanger system if an associated monitored temperature of the heat exchanger system needs adjustment, determining if the adjusted position of the variable actuator is within a predetermined range of positions, adjusting a position of a discrete actuator of the heat exchanger system if the adjusted position of the variable actuator is not within the predetermined range of positions, and resetting the position of the variable actuator in response to adjusting the position of the discrete actuator. | 10-02-2014 |
20140314130 | Harmonic Data Transfer In Rotary Wing Aircraft - A rotary wing aircraft includes a rotor assembly includes a rotor sensor generating a rotor sensor time domain signal; a rotor transform module converting the rotor sensor time domain signal to a rotor sensor frequency domain signal; and a rotor transceiver for transmitting the rotor sensor frequency domain signal over a transfer medium; an airframe assembly including: an airframe transceiver receiving the rotor sensor frequency domain signal; and an airframe transform module converting the rotor sensor frequency domain signal to the rotor sensor time domain signal. Signals from the airframe assembly may also be converted to the frequency domain prior to transfer over the transfer medium to the rotor assembly. | 10-23-2014 |
20140358333 | AIRSPEED ESTIMATION USING ROTOR VIBRATIONS - Embodiments are directed to determining, by a computing device comprising a processor, at least one parameter associated with a rotorcraft, obtaining, by the computing device, a profile of a vibration associated with the operation of the rotorcraft based on the at least one parameter, determining, by the computing device, an amplitude of the vibration using the profile, and determining, by the computing device, an airspeed of the rotorcraft based on amplitude. | 12-04-2014 |
20150151837 | PAYLOAD TOUCHDOWN DETECTION - Embodiments are directed to obtaining data associated with at least one aircraft flight parameter when an aircraft is being operated in flight; processing the data to determine that the at least one aircraft flight parameter indicates a change in value in an amount greater than a threshold; and decoupling a load from the aircraft based on determining that the at least one aircraft flight parameter indicates the change in value in the amount greater than the threshold. | 06-04-2015 |
20150314857 | CREW SEAT INTEGRAL INCEPTOR SYSTEM FOR AIRCRAFT - 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. | 11-05-2015 |
20150338850 | COOPERATIVE PERCEPTION AND STATE ESTIMATION FOR VEHICLES WITH COMPROMISED SENSOR SYSTEMS - A method and system for sharing information between independent agents having a processor and memory having instructions stored thereon that, when executed by the processor, cause the system to receive signals indicative of a fault of a sensor system of a first independent agent; transmit signals indicative of a request for sensor information to a second independent agent; receive signals indicative of state information for the second independent agent in response to the receiving of the request for sensor information; and apply the state information to a navigation system of the first independent agent in response to the receiving of the state information. | 11-26-2015 |
20150356875 | AIRCRAFT MOTION PLANNING METHOD - A method of route planning for a vehicle proceeding from a current location to a destination in a planning space is provided. The method includes generating a destination-rooted tree from global information that provides cost-to-go routing to the destination from multiple locations in the planning space, generating a vehicle-rooted tree using local information from the current location out to a sensing horizon and determining a local destination at the sensing horizon. The local destination corresponds to minimal cost-to-go routing obtained from the destination-rooted tree. | 12-10-2015 |
20150367956 | AIRCRAFT LANDING MONITOR - According to an aspect, a method of monitoring landing of an aircraft includes determining whether the aircraft is in a landing phase to maneuver the aircraft to a landing zone. Either or both of a landing profile monitor and a pattern matcher can set a landing instability indicator. The landing profile monitor compares aircraft sensor data indicative of a current state of the aircraft to a landing profile of the aircraft and sets the landing instability indicator based on the landing profile. The pattern matcher identifies a pattern associated with the landing zone in perception sensor data indicative of current conditions at the landing zone, monitors the pattern for a change indicative of landing zone instability, and sets the landing instability indicator based on detecting the change indicative of landing zone instability. Landing abort logic is triggered to abort landing based on determining that the landing instability indicator is set. | 12-24-2015 |
