  • Patent number: 11608187
    Abstract: A multi-rotor Aerial Vehicle with least rotors/propellers and having single arm failure redundancy is disclosed. The AV comprises at least five arms with at least one arm having a co-axial pair of contra rotating rotors/propellers. To maintain yaw stability under normal conditions, half of rotors/propellers are rotated in one direction and other half in opposite direction. In the event of failure of any one of the rotors/propellers located adjacent to the pair of contra rotating rotors/propellers, the one propeller/rotor out of the contra rotating rotor/propeller that is rotating opposite to the failed rotor/propeller is shut off. In the event of failure of a rotor/propeller belonging to contra rotating rotors/propellers, other rotor/propeller of the pair is shut off. In the event of failure of any one of rotors/propellers not adjacent to contra rotating rotors/propellers, the RPMs of other rotors/propellers is adjusted to maintain stability and navigate the Aerial Vehicle.

  • Patent number: 11603848
    Abstract: Embodiments of the inventive technology include a centrifugal fan having a damper repositionable between a closed position and a fully seated open position, and a magnetic coupler that serves to fully seat that damper it its open configuration, so as to prevent undesired effects such as slippage and/or rocking of that damper relative to rotatable componentry against which it is pressed, during operation of the fan. The coupler may be configured so that the damper may decouple from rotatable componentry, e.g., upon a certain reverse pressure differential, and translate to a closed position.

  • Patent number: 11603823
    Abstract: A method for ascertaining a wind direction at a wind power installation having a rotor on which at least one rotor blade is arranged. The method includes measuring first wind speeds in a predefined first measuring direction and second wind speeds in a predefined second measuring direction different from the first measuring direction in each case with a measuring frequency at a measuring point for a measuring period, wherein the measuring period is defined by a rotational distance of the rotor or by a prespecified time, wherein the rotor blade or one of the rotor blades passes the measuring point in the measuring period, and determining a wind direction by vectorial evaluation of the first wind speeds and of the second wind speeds.

  • Patent number: 11598311
    Abstract: A system and method are provided for controlling a wind turbine in response to a blade liberation event. Accordingly, estimated response signatures for the wind turbine are determined. Sensor data indicative of at least two actual response signatures of components of the wind turbine to a rotor loading are collected. The actual response signatures are compared to the estimated response signatures. The two or more actual response signatures meeting or exceeding the estimated response signatures is indicative of a blade liberation event. In response to detecting the blade liberation event, a rapid shutdown control logic is initiated to decelerate the rotor at a rate which exceeds a nominal deceleration rate of the rotor.

  • Patent number: 11598343
    Abstract: A fan system includes a motor, a rotatable hub, and a plurality of fan blades. The motor is coupled with the hub by a hollow drive shaft, such that the drive system of the fan system is gearless. The motor is controlled by a PFC-based control module, which is in communication with sensors that are configured to sense parameters associated with operation of the fan system. The control module is configured to react in certain ways to certain conditions detected by the sensors, such that the fan system uses feedback-based control algorithms. A remote control panel is in communication with the control module. The remote control panel is operable to display fault conditions detected by the sensors. Blade retainers prevent fan blades from falling when a fan blade breaks free from the hub. Pins prevent the hub from falling when the hub breaks free from the rotor.
