A method of operating an electrically powered rotorcraft of the type having a fuselage and a set of N rotors driven by a set of electric motors and coupled to the fuselage, N?4, under a failure condition preventing ordinary operation of the rotorcraft. The method includes entering a failsafe mode of operation wherein autorotation of at least four of the rotors is enabled. The method also includes using electrical braking associated with a selected group of the rotors to control pitch, roll and yaw of the rotorcraft.

An aircraft system includes an aircraft, which further includes at least one propeller to provide a flight power for the aircraft; a communication interface configured to communicate with a parachute; at least one storage medium, storing at least one set of instructions for controlling the aircraft system; and at least one processor in communication with the at least one memory. when the aircraft system is in operation, the at least processor executes the at least one set of instruction to: obtain a propeller locking instruction of the aircraft, and perform a corresponding operation based on the propeller locking instruction. The corresponding operation include a first operation. The first operation, corresponds to a scenario where the aircraft is in a flight state, includes: in response to the propeller locking instruction, the aircraft controlling the at least one propeller to stop and locking the at least one propeller, and deploying the parachute by the aircraft.

A computer-implemented system and associated method of operating a Small Uncrewed Aircraft System (SUAS) including at least one Small Uncrewed Aircraft or drone. The method comprises capturing data during operation of the SUAS from a number of sensors of different types, performing analysis on the captured data using one or more Artificial Intelligence/Machine Learning (AI/ML) models that have been trained on data sets including historical SUAS data and SUAS system fault data, to predict or identify a potential SUAS failure mode, and when a potential failure mode is predicted or identified, providing a course of action for further operation of the SUAS based on a severity and predicted timing of the SUAS failure mode.

An intelligent device for autonomous navigation of a drone comprising a control unit arranged to communicate with a remote-control station by a wireless connection, acquire a mission route ? that the drone is arranged to follow to reach a desired destination, the mission route ? being defined by means of coordinates x.sub.m(t), y.sub.m(t), z.sub.m(t) with respect to a reference system S(x,y,z), periodically acquire values x.sub.d, y.sub.d, z.sub.d corresponding to the components of the spatial position, values v.sub.x, v.sub.y, v.sub.z corresponding to the components of the speed and values a.sub.x, a.sub.y, a.sub.z corresponding to the components of the acceleration. Furthermore, in the event that a predetermined kinematic condition occurs, the control unit is arranged to check the status of the wireless connection with the remote-control station and, in the event that the wireless connection is active, send an alarm signal to the remote-control station and wait a response time t.sub.r.

Disclosed are methods, systems, and non-transitory computer-readable medium for controlling an automatic descent of a vehicle. For instance, the method may include: determining whether a descent trigger condition is present; and in response to determining the descent trigger condition is present, performing an automatic descent process. The automatic descent process may include: obtaining clearance data from an on-board system of the vehicle; generating a descent plan based on the clearance data, the descent plan including a supersonic-to-subsonic transition and/or a supersonic-descent to a target altitude; and generating actuator instructions to a control the vehicle to descend to the target altitude based on the descent plan.

A technique controls a flight vehicle. In the technique, an operating mode for controlling the flight vehicle is set to one of normal modes when no abnormality has occurred in the flight vehicle. The operating mode is changed to one of fail-safe modes causing the flight vehicle to perform landing depending on current one of the normal modes when an abnormality has occurred in the flight vehicle.

To provide a structure capable of further improving safety of a device that autonomously moves in an emergency situation. Provided is a circuit including: a report unit configured to report action-allowable time information regarding an action-allowable time to a base station; and an action control unit configured to control an action of a moving object on the basis of an action instruction decided on the basis of the reported action-allowable time information and notified of by the base station and to control an action with reference to a map in which a danger level for each place is defined in an emergency situation.

The present invention provides a method for decelerating and redirecting an airborne platform, comprising the steps of retaining a flexible airfoil in non-deployed form in controllably releasable secured relation with each corresponding rotor arm of a multi-rotor drone; and upon detecting rate of descent of said drone in a first direction to be greater than a predetermined value, triggering release of one or more of said retained airfoils from said corresponding rotor arm and causing each of said released airfoils to be circumferentially displaced from a first rotor arm to a second rotor arm of said drone to occlude an adjacent inter-arm region, wherein each of said circumferentially displaced airfoils generates a sufficient value of localized lift that causes said descending drone to change its direction of descent from said first direction to a second direction.
