Abstract
A method of capturing an aerial vehicle comprises rotating a first blade of the aerial vehicle, the first blade coupled to a hub of the aerial vehicle and having a contour configured to facilitate entanglement of a payload line of a winch system around the aerial vehicle. The method further comprises contacting, by a leading edge of the first blade, the payload line of the winch system and pulling the payload line towards the hub of the aerial vehicle, wherein the payload line is pulled towards the hub as the first blade continues to rotate and wherein continued rotation of the first blade causes the payload line to be tangled around the hub of the aerial vehicle.
Claims4
A method of capturing an aerial vehicle, the method comprising:
- rotating a first blade of the aerial vehicle, the first blade coupled to a first rotor of the aerial vehicle, wherein:
- the first blade has a contour configured to facilitate entanglement of a payload line of a winch system around a hub of the aerial vehicle;
- the contour comprising at least one feature positioned along a distal end of the first blade, the feature being configured to hook the payload line;
- the first rotor is positioned coaxial to a second rotor of the aerial vehicle;
- counter-rotating a second blade of the aerial vehicle, the second blade coupled to the second rotor that is coaxial to the first rotor;
- contacting, by a leading edge of the first blade, the payload line of the winch system;
- pulling the payload line towards the hub of the aerial vehicle, wherein the payload line is pulled towards the hub as the first blade continues to rotate;
- and
- wherein continued rotation of the first blade and continued counter-rotation of the second blade causes the payload line to be tangled around the hub of the aerial vehicle at a location on the hub that is between the first rotor and the second rotor.
