In order to cause a drone to fly in a stable manner, the present invention is characterized by having: a simulation device that executes, on each of a plurality of pieces of virtual wind condition data, a simulation of an air flow at a location where the drone will fly, outputs a simulation result that is the result of the simulation, and performs a flow field feature amount analysis on the simulation result, thereby calculating a flow field feature amount, and stores the flow field feature amount in an analysis result DB in association with the virtual wind condition data; and a wind condition estimating device that, on the basis of measured wind condition data, acquires a simulation result of the virtual wind condition data corresponding to the measured wind condition data and outputs the acquired simulation result to a drone control device.

A method and apparatus for reducing bending moment on a wing of an aircraft can include at least one sensor provided on the aircraft configured to monitor a shape or position of the wing. The sensor can provide a change in the position or shape of the wing to a controller. The controller can operate one or more spoilers in response to the change in shape or position of the wings to reduce loading on the wings to reduce the bending moment.

The systems and methods described herein relate to fully or partially autonomous or remotely operated aerial pollination vehicles that use computer vision and artificial intelligence to automatically detect plants, orient the vehicle to a pollen dispensing position above each plant, and pollinate the individual plants.

A system and method for determining the wind force along the planned trajectory of a projectile are disclosed herein. A drone is flown along the expected path of the trajectory along a set heading. The drone is programmed to maintain the heading. As wind forces act upon the drone during its flight, the drone's electronic stability system provides automatic power and directional control to one or more motors that control the rotors and propellers that keep the drone aloft. By monitoring the changes in motor or drone state information over time in response to wind forces, the wind can be determined at various locations along the flight path. This information can be provided to a ballistics calculator to determine the launch heading of the projectile.

An aircraft includes an airframe having an extending tail, and a counter rotating, coaxial main rotor assembly located at the airframe including an upper rotor assembly and a lower rotor assembly. A translational thrust system is positioned at the extending tail and providing translational thrust to the airframe. An active vibration control (AVC) system is located and the airframe and includes a plurality of AVC actuators configured to generate forces to dampen aircraft component vibration, and an AVC controller configured to transmit control signals to the plurality of AVC actuators thereby triggering force generation by the plurality of AVC actuators. A method of damping vibration of an aircraft includes receiving a vibration signal at an AVC controller, communicating a control signal from the AVC controller to a plurality of AVC actuators, generating a force at the AVC actuators, and damping vibration of the aircraft via the generated force.

Method and device for determining trajectory to optimal position of a follower aircraft with respect to vortices generated by a leader aircraft. The method includes controlling trajectory of a follower aircraft to an optimal position where the follower aircraft benefits from effects of at least one of the vortices of a leader aircraft. A first section control step controls flight of the follower aircraft using current measurements of flight parameters, from a safety position to a search position, along an approach section passing through an approach zone. A second section control step controls flight of the follower aircraft using current measurements of flight parameters, from the search position to a precision position, along a search section passing through a search zone, and a third section control step controls flight of the follower aircraft, from the precision position to the optimal position, along an optimization section passing through an optimization zone.

Apparatus and methods for controlling an aircraft and/or a vehicle are described. A vehicle speed and direction are received. A wind-over-vehicle speed and direction of wind at the vehicle are measured. An aircraft ground speed and direction are received. An aircraft-relative-to-vehicle speed and an aircraft-relative-to-vehicle direction are calculated based on the aircraft ground speed and direction and the wind-over-vehicle speed and direction. A wind-over-vehicle envelope is calculated based on system design limits for retrieving the aircraft at the vehicle. The wind-over-vehicle envelope maps limits of wind-over-vehicle speeds over a range of directions that enable retrieval of the aircraft at the vehicle. The aircraft and/or the vehicle are controlled using the wind-over-vehicle envelope, the aircraft-relative-to-vehicle speed, and/or the aircraft-relative-to-vehicle direction.

A plurality of electronic nodes sense, in real-time, micro-weather data. Each of the plurality of electronic nodes is communicatively coupled to an electronic aggregation node. The electronic aggregation node is configured to receive the micro-weather data. A control circuit is further configured to determine, based upon an analysis of the micro-weather data, and micro-weather conditions occurring in a limited geographic area, and a recommendation for a suggested maneuver to an aerial drone. The recommendation is effective to advantage the operation of the drone while operating within the geographic area under the micro-weather conditions.
