Abstract:
In general, certain embodiments of the present disclosure provide a detection and avoidance system for a vehicle. According to various embodiments, the detection and avoidance system comprises an imaging unit configured to obtain a first image of a field of view at a first camera channel. The first camera channel filters radiation at a wavelength, where one or more objects in the field of view do not emit radiation at the wavelength. The detection and avoidance system further comprises a processing unit configured to receive the first image from the imaging unit and to detect one or more objects therein, as well as a notifying unit configured to communicate collision hazard information determined based upon the detected one or more objects to a pilot control system of the vehicle. Accordingly, the pilot control maneuvers the vehicle to avoid the detected objects.
Abstract:
An example method includes determining, by a flight planning system, a perceived noise at a surface location based on acoustic noise emitted by an aerial vehicle at an aerial location. The aerial location corresponds to a waypoint along a proposed trajectory. Further, determining the perceived noise includes estimating propagation of the acoustic noise from the aerial location to the surface location based on environmental features of the environment or weather data. The flight planning method also includes determining, by the flight planning system using a noise-abatement function, a noise-abatement value of the proposed trajectory for the aerial vehicle based on the perceived noise at the surface location. In addition, the flight planning method includes determining, by the flight planning system, a flight plan for the aerial vehicle based on the noise-abatement value of the proposed trajectory, and outputting the flight plan for use in navigating the aerial vehicle.
Abstract:
In an example, a power source for an electric propulsion system of an aerial vehicle includes a body having an electrical energy storage device configured to store electrical energy. The power source also includes a plurality of terminals coupled to the electrical energy storage device for supplying the electrical energy from the electrical energy storage device to the electric propulsion system of the aerial vehicle. The power source further includes a plurality of flight control surfaces extending outwardly from the body. The flight control surfaces are actuatable to adjust a flight attitude of the power source. Additionally, the power source includes a flight control system including a processor and configured to actuate the plurality of flight control surfaces to fly the power source to a target location when the power source is jettisoned from the aerial vehicle.
Abstract:
An apparatus comprises a base vehicle, a takeoff and landing system, a rack system, a refueling system associated with the base vehicle, and a controller. The rack system comprises a group of racks with slots in which the slots receive unmanned aerial vehicles, provide refueling connections that facilitate refueling of the unmanned aerial vehicles located in the slots, and provide data connections that facilitate data transmission with the unmanned aerial vehicles located in the slots. The refueling system refuels an unmanned aerial vehicle located in a slot using a refueling connection in the refueling connections. The controller communicates with the unmanned aerial vehicle using a data connection and control the refueling of the unmanned aerial vehicles by the refueling system while the unmanned aerial vehicle is in the slot, enabling exchanging data with the unmanned aerial vehicle and the refueling of the unmanned aerial vehicle simultaneously.
Abstract:
A method and apparatus for operating an aircraft. The aircraft is flown at a constant bank angle in which the aircraft crosses an intended ground track for the aircraft. Information is identified about a wind using positions of the aircraft flying at the constant bank angle.
Abstract:
A system and methods for coordinating positioning of vehicles in motion is disclosed. The method graphically presents displayed synchronization parameters on a display screen such that a user determines a planned position of a first vehicle on a planned path in order to arrive at a predetermined position at a correct time. The method further synchronizes the first vehicle with the planned position on the planned path using the displayed synchronization parameters and performs a rendezvous between the first vehicle and a second vehicle.
Abstract:
A method and apparatus for managing a location. Soil sensor units are deployed in the location in a forest from a group of aerial vehicles. Information is generated about a number of soil conditions in the location in the forest using the soil sensor units in the location. The information is transmitted from the soil sensor units to a remote location for analysis.

Abstract:
Systems and methods for determining, prior to deployment of a landing assist device onboard an aircraft, the positions of potential landing sites for the aircraft. The positions of the potential landing sites are determined by a computer based at least in part on respective landing assist device deployment times and current wind data. The computed positions of potential landing sites are received by another computer or processor onboard that aircraft that is configured to control operation of a cockpit display unit within the field of view of the pilot. The display unit displays a map showing the respective positions of the aircraft at the respective landing assist device deployment times and the corresponding respective positions of the potential landing sites.
Abstract:
An example air vehicle includes a transponder to transmit a code indicative of a communications systems failure on the air vehicle. The example air vehicle includes a satellite receiver to receive, after the transponder code has been transmitted, a message from a satellite in communication with the air vehicle. The satellite receiver is to identify the message as including a command for the air vehicle and decode the message to determine the command. The example air vehicle includes a processor to execute the command.
