Abstract:
A drone traffic management system comprising a computer comprising memory means for storing origin coordinates indicating an origin location of a drone, destination coordinates indicating a destination of the drone, and traffic management factors located between the origin location of the drone and the destination of the drone; and processing means for controlling the flight of a drone. This is accomplished by calculating a flight path for the drone to fly automatically from the origin location to the destination location without manual intervention, sending the flight path to the drone, receiving location data of the drone as it travels from the origin location to the destination, re-calculating the flight path of the drone as a function of the traffic management factors and the location data of the drone, and sending the re-calculated flight path to the drone.
Abstract:
The Dynamic Turbulence Engine Controller Apparatuses, Methods And Systems ("DTEC") transform weather, terrain, and flight parameter data via DTEC components into turbulence avoidance optimized flight plans. In one implementation, the DTEC comprises a processor and a memory disposed in communication with the processor and storing processor-issuable instructions to receive anticipated flight plan parameter data, obtain terrain data based on the flight plan parameter data, obtain atmospheric data based on the flight plan parameter data, and determine a plurality of four-dimensional grid points based on the flight plan parameter data. The DTEC may then determine a non-dimensional mountain wave amplitude and mountain top wave drag, an upper level non-dimensional gravity wave amplitude, and a buoyant turbulent kinetic energy. The DTEC determines a boundary layer eddy dissipation rate, storm velocity, and eddy dissipation rate from updrafts, maximum updraft speed at grid point equilibrium level and storm divergence while the updraft speed is above the equilibrium level and identify storm top. The DTEC determines storm overshoot and storm drag, Doppler speed, eddy dissipation rate above the storm top, and determine eddy dissipation rate from downdrafts. The DTEC then determines the turbulent kinetic energy for each grid point and identifies an at least one flight plan based on the flight plan parameter data and the determined turbulent kinetic energy.
Abstract:
The invention relates to a system (100) for motorized displacement of a mobile element (200), comprising at least two actuators (1, 2) which are each provided with means for linking them to the mobile element and which are dimensioned so as to be able to manoeuvre only the mobile element, a central control unit (3) being connected to the two actuators so as to send each of the actuators a position setpoint (Pos1, Pos2). According to the invention, the system comprises control means (10, 20) for simultaneously controlling the two actuators in terms of load in response to the position setpoint dispatched to one of the actuators. The invention also relates to a method of driving such a system and a method of testing such a system.

Abstract:
An aircraft comprising a device for influencing the directional stability of the aircraft, which aircraft comprises: a control-input device; a flight control device; a sensor device for acquiring the rotation rates including the yaw rates, of the aircraft; - wherein the aircraft comprises two tail-mounted flaps (K1, K2), each comprising an actuator that is functionally connected with the flight control device, which tail-mounted flaps (K1, K2) are situated symmetrically to each other in relation to the vertical axis and on opposite sides of the fuselage and are movable between a retracted and an extended position, - wherein the control function is designed in such a manner that the adjusting commands that are generated on the basis of the control commands depending on the acquired rotation rates comprise adjusting commands to the actuators of the tail-mounted flaps (K1, K2) for their actuation, as well as a method for influencing the directional stability of the aircraft (F).
Abstract:
A method for vertical gust suppression due to turbulence for an aircraft having at least one of direct lift control surfaces or pitch control surfaces. The method includes sensing atmospheric turbulence, measuring the sensed atmospheric turbulence to generate turbulence data, generating a command based on the turbulence data, and applying the command to aircraft controls to actuate the direct lift control surfaces or the pitch control surfaces based on the turbulence data. Therefore, an aircraft response to the actuation of the direct lift control surfaces or the pitch control surfaces reduces a vertical acceleration, a pitch acceleration, a pitch rate, a pitch attitude or a structural load of the aircraft due to the turbulence. Thus, the method reduces the effects of vertical gusts of wind on the aircraft, improves the comfort level for aircraft passengers and crew, and reduces diversions the aircraft may take to avoid the turbulence.
