Proposed is a system and method of controlling safety devices of a rotary-wing aircraft, the system and method preventing indiscreet operation of safety devices by automatically or manually deploying the safety devices in accordance with the risk levels of accidents. The system includes sensors configured to detect motions of the aircraft, and a controller configured to control risk levels of accidents in flight on the basis of signals from the sensors and configured to control safety devices mounted on the aircraft to be automatically or manually operated, depending on risk levels of accidents.

A vertical take-off and/or landing aircraft comprising: a fuselage having a longitudinal axis; a pair of semi-wings protruding from the fuselage in a transversal direction with respect to the longitudinal axis; a pair of a predetermined breaking areas of the semi-wings defining respective preferred rupture sections at which the respective semi-wings are designed to break, during operation, in a controlled way moving along a preferred collapse trajectory in the event of impact; and at least one fluidic line configured to convey at least one service fluid from and/or towards at least one said semi-wing and crossing at least one of said preferred rupture sections; the aircraft comprises a self-sealing coupling movable between a first configuration in which it enables the flow of said service fluid from and/or towards the semi-wing, and a second configuration in which it prevents the above-mentioned flow and the spilling of the service fluid from the fluidic line; the self-sealing coupling is movable from the first to the second configuration via the movement of the semi-wing along the preferred collapse trajectory.

A control and monitoring device for a vehicle, and, more particularly, to a control and monitoring device for a vehicle with a controllable device, whereby the vehicle is operated by a vehicle operator wearing a personalized wearable device. The control and monitoring device may include a vehicle management system that is adapted to send alert information to and to receive status information from the personalized wearable device via a wireless radio transmitter and receiver unit. The status information may include at least one of preferred workspace settings of the vehicle operator or health-related information about the vehicle operator. The vehicle management system may control the controllable device based on the at least one of the preferred workspace settings or the health-related information.

An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; a balloon that laterally covers the plurality of rotor units, across a height of the plurality of rotor units in an up-and-down direction; and a drive unit configured to change the external shape of the balloon at a predetermined timing.

Systems and methods for operating an engine in a multi-engine rotorcraft are described herein. A first parameter indicative of torque of a first engine is obtained. A decrease of the first parameter is detected. In response to detecting the decrease of the first parameter, an autorotation of the rotorcraft is accommodated, A second parameter indicative of torque of a second engine of the rotorcraft is assessed while accommodating the autorotation. If the second parameter has not decreased, a shaft shear of the first engine is identified and accommodating of the autorotation is ended. If the second parameter has decreased, the accommodating is maintained.

A fail safety apparatus of the air mobility is provided. Locations of propeller modules are adjusted by rotation parts and length adjustment units to evenly distribute thrust of the re-located propeller modules so that the attitude of the air mobility is stabilized. In particular, when one propeller module among a plurality of propeller modules fails, the attitude of the air mobility is normalized by adjusting a location of the failed propeller module and locations of remaining normal propeller modules so that flight safety of the air mobility is secured.

Systems, devices, and methods for stopping the rotation of propellers used in unmanned aerial vehicles (UAV) such as drones are disclosed. The propellers are stopped in response to detecting when beams of light adjacent the propellers are blocked.

A propeller guard 10 includes an upper frame 12 provided on the uppermost surface of the propeller guard 10, a base frame 15 provided on the lowermost surface of the propeller guard, and a curved frame 18 that couples the upper frame 12 and the base frame 15 together and is curved outward.

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.

Rescue parachute deployment systems (RPDSs) and related techniques are provided to improve the safety and operational flexibility of unmanned aerial vehicles (UAVs). An RPDS includes a canopy assembly, a rotor guard disposed at least partially about the canopy assembly and configured to protect the canopy assembly from rotor strike damage as the canopy assembly is launched through a rotor plane of the UAV, and an ejector assembly configured to deploy the rotor guard into and the canopy assembly through a rotor plane of the UAV. The RPDS may also include a logic device coupled to and/or integrated with the ejector assembly and/or the UAV that is configured to determine a rescue parachute launch condition is active and to control the ejector assembly to deploy the canopy assembly through the rotor plane of the UAV.
