Line capture devices for unmanned aircraft, and associated systems and methods are disclosed. A system in accordance with a particular embodiment includes a line capture device body having a line slot with an open end and a closed end. A retainer is positioned proximate to the line slot and has a rotor with a plurality of rotor arms positioned to extend at least partially across the line slot as the rotor rotates relative to the body. A joint rotatably couples the rotor to the body, and a ratchet device is operably coupled to the rotor to allow the rotor to rotate in a first direction and at least restrict the rotor arm from rotating in a second direction opposite the first. In other embodiments, the retainer can include other arrangements, for example, one or more wire-shaped elements.

The system of claim 1 wherein the line capture device body includes a base portion and a cover portion carried by the base portion, with at least part of the base portion spaced apart from at least part of the cover portion to define, at least in part, a rotor slot, and wherein the rotor is rotatably positioned between the base portion and the cover portion in the rotor slot. 3. The system of claim 2 wherein the ratchet device includes a ratchet tab projecting inwardly into the rotor slot from at least one of the base portion and the cover portion, the ratchet tab being sloped inwardly into the rotor slot. 4. The system of claim 2 wherein at least one of the base portion and the cover portion includes a tab and wherein the other of the base portion and the cover portion includes an alignment slot positioned to receive the tab and resist relative motion between the cover portion and the base portion. 5. The system of claim 1 wherein the line capture device body has a first surface and a second surface facing away from the first surface, and wherein the rotor is a first rotor positioned adjacent to the first surface, and wherein the system further comprises a second rotor positioned adjacent to the second surface and rotatably coupled to the line capture device body, the second rotor having a plurality of rotor arms positioned to extend at least partially across the line slot as the second rotor rotates relative to the line capture device body. 6. The system of claim 1 wherein individual rotor arms have ends positioned radially outwardly from a pin, and wherein the ratchet device includes a spring positioned to successively engage with the ends of corresponding individual rotor arms as the rotor rotates relative to the line capture device body. 7. The system of claim 1 wherein the line slot is tapered between the open end and the closed end. 8. The system of claim 1, further comprising an aircraft having a fuselage and a wing, and wherein the line capture device body is attached to the wing. 9. The system of claim 8 wherein the line capture device body has a leading edge, and wherein the leading edge is swept aft relative to the fuselage. 10. The system of claim 8 wherein the line capture device body is positioned away from an outboard edge of the wing. 11. The system of claim 1, further comprising: a recovery line; anda support carrying the recovery line. 12. An aircraft system, comprising: a line capture device having a line capture device body, a rotor rotatably attached to the line capture device body, and a ratchet device configured to restrict a first direction of rotation of the rotor relative to the line capture device body; wherein the rotor comprises a hub and a plurality of rotor arms extending outwardly from the hub,wherein the line capture device body includes a line slot configured to receive a recovery line, andwherein at least a portion of the rotor is positioned to extend at least partially across the line slot when the rotor is in a first orientation relative to the line capture device body. 13. The system of claim 12 wherein the line capture device body includes a base portion, a cover portion carried by the base portion, and a rotor slot defined at least in part by a space between a surface of the base portion and a surface of the cover portion, and wherein the rotor is positioned at least partially within the rotor slot. 14. The system of claim 13 wherein at least one of the base portion and the cover portion includes a tab and wherein the other of the base portion and the cover portion includes an alignment slot positioned to receive the tab. 15. The system of claim 12 wherein the ratchet device includes a ratchet tab bent toward an interior opening of the line capture device body. 16. The system of claim 12 wherein: the line capture device body has a first surface and a second surface facing away from the first surface;the rotor includes a first rotor portion positioned adjacent to the first surface and a second rotor portion positioned adjacent to the second surface; and whereinthe system further comprises an axle connecting the first rotor portion to the second rotor portion. 17. The system of claim 12 wherein the ratchet device includes an elongated spring positioned to engage at least a portion of the rotor. 18. The system of claim 12 wherein the line capture device is a first line capture device, and wherein the system further comprises a second line capture device. 19. An aircraft system, comprising: a line capture device body attached to a wing of an aircraft and having a line slot with an open end and a closed end, the line slot being configured to receive a recovery line; a rotor comprising a hub and a plurality of rotor arms extending outwardly from the hub, the rotor rotatably coupled to the line capture device body, at least a portion of the rotor extending at least partially across the line slot when the rotor is in at least one orientation relative to the line capture device body; anda ratchet device; whereinthe rotor is positioned to rotate in a first direction when the recovery line presses against the portion of the rotor, and whereinthe ratchet device is positioned to allow the rotor to rotate in the first direction and limit rotation of the rotor in a second direction opposite the first direction.
