摘要： An unmanned rotorcraft 101 includes an airframe 103, rotor blades 105 that are coupled to the airframe 103 for rotation therewith, a propulsion unit 107 having a propeller 109, and an actuator 137 that is coupled to the airframe 103 and adapted to temporarily reorient the propulsion unit 107 such that an axis 123 of the propeller 109 moves out of alignment with an axis 117 of the rotor blades 105. Rotation of the propeller 109 causes counter-rotation of the airframe 103 and rotor blades 105. The rotor blades 105 and blades 111 of the propeller 109 are adapted to deploy from collapsed positions when flight of the rotorcraft 101 is initiated. A method of operation by the rotorcraft 101 includes, when it is determined that a current heading does not correspond to a determined flight path, causing the actuator 137 to temporarily reorient the propulsion unit 107 in accordance with an angular orientation of the actuator 137 relative to the current heading.

摘要： Systems and methods for countering an unmanned air vehicle are disclosed. Representative systems include an interceptor UAV for disabling a target UAV, the interceptor UAV comprising: a flight vehicle having: a cylindrical fuselage elongated along a fuselage axis; four fins carried by the fuselage and arranged in a cruciform, each fin having a fin slot extending from the fuselage in an outboard direction transverse to the fuselage axis; a propulsion system that includes: a first propeller carried by the fuselage and rotatable about the fuselage axis in a first direction to sequentially pass in and out of successive fin slots; a second propeller carried by the fuselage and rotatable about the fuselage axis in a second direction opposite the first direction to sequentially pass in and out of the successive fin slots; a power source carried by the fuselage, the power source including a first electric motor coupled to the first propeller to rotate the first propeller in the first direction, and a second electric motor coupled to the second propeller to rotate the second propeller in the second direction; and a stored electrical energy source coupled to the first and second electric motors; at least one control surface carried by at least one of the fins; a guidance system coupled to the at least one control surface; and a deployable net carried by the flight vehicle and having a first, inactive mode and a second, active mode, wherein in the second mode, the deployable net is deployed from the flight vehicle to disable the target UAV. Representative methods include directing an interceptor UAV toward the target UAV; and disabling the target UAV by deploying a disabling element from the interceptor UAV to contact the target UAV.

摘要： Aeronautical propulsion device for an aircraft with carrier wings for cruise flight.
The propulsion device comprises at least two coaxial propellers (1, 2) counter-rotating therebetween.
Said propellers (1, 2) have a fixed and different pitch therebetween, having a first said propeller (1) of smaller pitch and having a second said propeller (2) of larger pitch.

摘要： A rotary propulsion system includes a fan arranged along a rotation axis, an electric motor (114) having windings (116) and a permanent magnet (118) arranged along the rotation axis and operatively connected to the fan (102), and a reduction gear set (120). The reduction gear set extends about the rotation axis and couples the electric motor to the fan. The permanent magnet is rotatable relative to the windings and the fan to rotate the fan using the electric motor at a rotational speed that is lower than a rotational speed of the permanent magnet. Aircraft and methods of propelling aircraft are also described.
