    Abstract: Sounds are generated by an aerial vehicle during operation. For example, the motors and propellers of an aerial vehicle generate sounds during operation. Disclosed are systems, methods, and apparatus for actively adjusting the shape of a propeller blade of an aerial vehicle during operation of the aerial vehicle. For example, the propeller blade may have one or more joints that adjust to alter the shape of the propeller blade. The altered shape of the propeller blade causes the propeller to generate different frequencies of sound as it rotates. By altering multiple propeller blades of the aerial vehicle, the different sounds generated by the different propeller blades may effectively cancel or reduce the total sound generated by the aerial vehicle, and/or alter the total frequency generated.

  • Patent number: 9984581
    Abstract: A piloting assistance method for avoiding an obstacle with a rotorcraft flying along a current speed vector (Vect0). An alert is generated by using a speed vector of the rotorcraft referred to as a “calculation” speed vector (Vect1) in order to determine whether the rotorcraft might impact an obstacle. During a correction stage and at each calculation iteration, the calculation speed vector (Vect1) is determined using a horizontal component and a vertical component, the vertical component being a function of a current vertical speed of the rotorcraft relative to the ground corrected with a corrective term, the corrective term being a function of a product of a current path speed of the rotorcraft multiplied by the derivative of the path speed.

  • Patent number: 9944387
    Abstract: A stoppable rotor, which includes a first and second blade and rotates about a substantially vertical axis, is stopped with the first blade pointing forward and the second blade pointing backward while the aircraft is mid-flight. Anti-torque is provided using a set of one or more combination rotors in a first mode of operation in order to counter torque produced by the stoppable rotor when the stoppable rotor is rotating where the set of combination rotors rotate about a substantially longitudinal axis. Forward thrust is provided using the set of combination rotors in a second mode of operation when the stoppable rotor is not rotating.

  • Patent number: 9889930
    Abstract: This disclosure describes a configuration of an unmanned aerial vehicle (UAV) that includes a frame that provides both structural support for the UAV and protection for foreign objects that may come into contact with the UAV. The UAV may have any number of lifting motors. For example, the UAV may include four lifting motors (also known as a quad-copter), eight lifting motors (octo-copter), etc. Likewise, to improve the efficiency of horizontal flight, the UAV may also include one or more pushing motor and propeller assemblies that are oriented at approximately ninety degrees to one or more of the lifting motors. When the UAV is moving horizontally, the pushing motor(s) may be engaged and the pushing propeller(s) will aid in the horizontal propulsion of the UAV.

  • Patent number: 9835935
    Abstract: A telescoping extension device for camera phones utilizes an extendable, telescoping pole, a control handle located at the first end of the pole, and a camera phone holder designed to support a camera phone attached at the upper or second end of the pole. A propeller blade assembly, consisting of propeller blades and an electric motor, is attached to the second end of the pole. A propeller blade control switch located on the control handle provides a remote signal to the motor to control the off and on rotation and speed of the blades. By actuating the motor and rotating the blades, a “helicopter” effect is created, resulting in the second end of the pole to be lifted, thereby increasing the photographic field of vision of the camera phone.
