摘要： A method for computing drop zone data onboard an aircraft is provided. The method obtains, by a processor, current drop zone parameters for an air drop, during flight of the aircraft; receives, by the processor, changes to dynamic conditions associated with operation of the aircraft, wherein the dynamic conditions comprise at least one of wind speed, drop altitude, current temperature, angle of approach, aircraft speed, and number of stages of planned drop; calculates, by the processor, updated drop zone parameters, based on the current drop zone parameters and the changes to the dynamic conditions; and presents the updated drop zone parameters, via a display device.

摘要： A vehicle (100) comprising: an engine (102); a system for starting the engine (102); a fault detection module (120); an electrical power source (110); and a controller (116, 122). The controller (116, 122) is configured to, responsive to the fault detection module (120) detecting a fault occurring with the engine (102): determine a window in which to attempt to start the engine (102); control the electrical power source (110) to provide electrical power to the system for starting the engine (102); and control the system for starting the engine (102) to attempt to start the engine (102) using the supplied electrical power only during the determined window.

摘要： A balloon includes a cut-down device, a payload, and an envelope. A control system could be configured to determine a position of the balloon with respect to a predetermined zone. The cut-down device could be operable to cause at least the payload to land in response to determining that the position of the balloon is within the predetermined zone. The predetermined zone includes an exclusion zone and a shadow zone. The shadow zone could include locations from which the balloon would be likely to drift into the exclusion zone based on, e.g., historic weather patterns or expected environmental conditions. Boundaries of the shadow zone could be determined based on, for example, a probability of the balloon entering the exclusion zone.

摘要： The invention relates to remote control of an unmanned aerial vehicle, UAV, (100) from a control station (110) by means of a wireless command link (115). The UAV (100) may be controlled in an autonomous mode wherein it flies according to a primary route (R1, R1') defined by a first set of predefined waypoints (WP1-WP8, IP). The UAV (100) may also be controlled in a manual mode wherein it flies according to an alternative primary route (R1') defined in real-time by control commands received via the wireless command link (115). Flight control parameters are monitored in both modes, and in case a major alarm condition occurs, the UAV (100) is controlled to follow an emergency route (R2') defined by a second set of predefined waypoints (HP1-HP7, TP1-TP9, IP). Particularly, a major alarm condition is activated if an engine failure is detected. Then, the emergency route (R2') involves flying the UAV (100) to an air space above a termination waypoint (TP9) on the ground at which it is estimated that the vehicle's (100) flight may be ended without injuring any personnel or causing uncontrolled material damages.

摘要： An automatic guidance system guides a flight vehicle having a parafoil to a target grounding point. The system opens the parafoil of the flight vehicle dropped in a predetermined area above the target grounding point. The system estimates wind velocity and wind direction after the parafoil of the flight vehicle is opened. Then, the system determines the landing flight path of the flight vehicle based on the estimated wind velocity and wind direction, guides the flight of the flight vehicle to the determined landing flight path and descends the flight vehicle according to the landing flight path.

摘要： The positions of balloons in a communication network of balloons, such as a mesh network of high-altitude balloons, may be adjusted relative to one another in order to try to maintain a desired network topology. In one approach, the position of each balloon may be adjusted relative to one or more neighbor balloons. For example, the locations of a target balloon and one or more neighbor balloons may be determined. A desired movement of the target balloon may then be determined based on the locations of the one or more neighbor balloons relative to the location of the target balloon. The target balloon may be controlled based on the desired movement. In some embodiments, the altitude of the target balloon may be controlled in order to expose the target balloon to ambient winds that are capable of producing the desired movement of the target balloon.

摘要： Method for autonomous safe emergency landing of a powered unmanned aerial vehicle (UAV) in the event of an engine failure. A landing approach trajectory is generated, including a downwind leg, initiating at an initiation point of the trajectory, an upwind leg, terminating at a selected touchdown point, and a U-turn leg, joining between the downwind leg and the upwind leg. The UAV is directed to the initiation point to follow the downwind leg. A glide ratio of the UAV is repeatedly determined based on current flight conditions. A current turning point is repeatedly determined along the downwind leg based on the determined glide ratio, the U-turn leg initiating at the current turning point. When the UAV arrives at the current turning point, the UAV is directed to follow the U-turn leg and the upwind leg, for landing the UAV at the selected touchdown point.

摘要： A method and apparatus for changing a flight path of an air platform. A change for the flight path of the air platform is identified. A weight system associated with the air platform is moved during flight of the air platform such that a center of mass of the air platform changes in a manner that causes the flight path of the air platform to change.
