A SYSTEM FOR DRONES STABILIZATION, WITH IMPROVED FLIGHT SAFETY
A flight safety drone stabilization system for drones, comprising an onboard controller which is configured to continuously detect in-flight unbalancing loading by receiving signals from suitable onboard sensors (e.g., gyroscopes) and/or from unbalancing load triggering components. Responsive to the detection of unbalancing loading, the system is further configured to control an individual motor or a combination of multi-propeller drone motors, to balance the unbalancing loading and to proactively compensate for unbalancing loading induced by planned in-flight operations. During balancing, the onboard controller increases the thrust of one or more of the multi-propeller drone motors being in opposite direction to the location of the unbalancing loading, or reduces the thrust of one or more of the multi- propeller drone motors being in the vicinity of the location of the unbalancing loading, by manipulating the amplitude and/or the intensity of electric pulses sent to individual multi-propeller drone motors or to a combination of multi-propeller drone motors (e.g., by a transducer being controlled by the onboard controller).
A flight safety drone stabilization system for drones, comprising an onboard controller (i.e., either integrated or add-on with a drone's flight controller) which is configured to a) continuously detect in-flight unbalancing loading (which may be generated following shooting in case of a weapon-carrying drone) by receiving signals from suitable onboard sensors (e.g., gyroscopes) and/or from unbalancing load triggering components; b) responsive to the detection of unbalancing loading, control an individual motor or a combination of multi-propeller drone motors, to balance the unbalancing loading; c) proactively compensate for unbalancing loading induced by planned in-flight operations. During balancing, the onboard controller increases the thrust of one or more of the multi-propeller drone motors being in opposite direction to the location of the unbalancing loading, or reduces the thrust of one or more of the multi-propeller drone motors being in the vicinity of the location of the unbalancing loading, by varying the power delivered to individual multi-propeller drone motors or to a combination of multi-propeller drone motors.
