VEHICLE CAPTURE ASSEMBLIES AND RELATED DEVICES, SYSTEMS, AND METHODS
Vehicle capture assemblies and related devices, systems, and methods include one or more probe assemblies for passively engaging with and securing the target vehicle.
1 . A vehicle capture assembly, comprising:
a probe assembly including one or more retention elements for engaging with and securing a target vehicle in a deployed position, the probe assembly configured to passively engage with and secure the target vehicle with the one or more retention elements in the deployed position;
a biasing element for biasing the one or more retention elements in the deployed position, the one or more retention elements configured to be moved toward a stowed position against a force of the biasing element in response to a force applied to the one or more retention elements;
an extendable lance coupled to the probe assembly, the probe assembly being positioned at a distal portion of the lance; and
an actuation element coupled to the one or more retention elements by one or more linkages, the actuation element for interacting with the biasing element to bias the one or more retention elements in the deployed position and to return the one or more retention elements to the deployed position after being forced into the stowed position.
2 . The vehicle capture assembly of claim 1 , wherein translation of the actuation element away from the one or more retention elements is configured to move the one or more retention elements into the stowed position in order to release the target vehicle.
3 . The vehicle capture assembly of claim 1 , wherein the one or more retention elements are configured to move past the deployed position and away from the stowed position in a direction toward the target vehicle to an overextended position where the one or more retention elements release the target vehicle.
4 . The vehicle capture assembly of claim 1 , wherein translation of the lance in a direction toward the target vehicle is configured to move the one or more retention elements into the stowed position in order to release the target vehicle.
5 . The vehicle capture assembly of claim 1 , wherein the one or more retention elements are biased in the deployed position.
6 . The vehicle capture assembly of claim 5 , wherein the one or more retention elements are configured to move past the deployed position in a direction toward the target vehicle to an overextended position where the one or more retention elements release the target vehicle.
7 . The vehicle capture assembly of claim 1 , further comprising at least one clamp configured to engage with a docking cone of the target vehicle after the target vehicle has been secured by the probe assembly.
8 . The vehicle capture assembly of claim 7 , wherein, after engagement, the at least one clamp comprises a primary connection between the target vehicle and the vehicle capture assembly.
9 . The vehicle capture assembly of claim 1 , wherein the vehicle capture assembly comprises two or more capture arms, each of the two or more capture arms comprising a respective combination of a probe assembly and an extendable lance that is at least partially independent from the probe assembly and the extendable lance of another capture arm of the two or more capture arms.
10 . The vehicle capture assembly of claim 9 , wherein the two or more capture arms are each configured to be mounted at a location on a capture vehicle that is offset from a centerline of the capture vehicle and from primary propulsion devices of the capture vehicle.
11 . A spacecraft capture system, comprising:
two or more vehicle capture assemblies, each comprising:
a probe assembly including one or more retention elements for engaging with and securing a target spacecraft; and
an extendable lance coupled to the probe assembly, the probe assembly being positioned at a distal portion of the lance, wherein the probe assembly is configured to engage with a portion of the target spacecraft;
wherein the two or more vehicle capture assemblies are configured to substantially simultaneously retract each respective probe assembly of the two or more vehicle capture assemblies in order to secure the target spacecraft.
12 . The spacecraft capture system of claim 11 , wherein each of the two or more vehicle capture assemblies are configured to substantially define a universal joint between the target spacecraft and the capture system when the probe assembly of each of the two or more vehicle capture assemblies is received in and engaged with a respective docking cone of the target spacecraft.
13 . The spacecraft capture system of claim 11 , wherein the probe assembly the extendable lance of each of the two or more vehicle capture assemblies are partially independent from the probe assembly and the extendable lance of another of the two or more vehicle capture assemblies.
14 . The spacecraft capture system of claim 11 , wherein the two or more vehicle capture assemblies are each configured to be mounted at a location on a capture vehicle that is offset from a centerline of the capture vehicle and from primary propulsion devices of the capture vehicle.
15 . A method of capturing a target spacecraft, the method comprising:
biasing one or more barbs of a probe of a vehicle capture assembly in a deployed position with an actuation element coupled to the one or more barbs;
inserting the one or more barbs into a docking element of the target spacecraft;
at least partially retracting the one or more barbs to a retracted position in response to a force applied to the one or more barbs by the target spacecraft;
moving the one or more barbs back to the deployed position to secure the one or more barbs to the docking element with the actuation element;
moving the actuation element along the probe against a biasing force;
in response to moving the actuation element, moving the one or more barbs to a release position; and
disengaging the one or more barbs from the docking element of the target spacecraft.
16 . The method of claim 15 , wherein moving the one or more barbs to the release position comprises forcing the one or more barbs in a direction toward the retracted position.
17 . The method of claim 15 , wherein moving the one or more barbs to the release position comprises forcing the one or more barbs in a direction away from the retracted position and toward the target spacecraft with a force applied to the one or more barbs with the target spacecraft.
18 . The method of claim 15 , further comprising destructively releasing the target spacecraft by detonating one or more explosive unions to disengage the target spacecraft from the probe.
19 . The method of claim 15 , further comprising nondestructively releasing the target spacecraft to disengage the target spacecraft from the probe.
20 . The method of claim 19 , wherein nondestructively releasing the target spacecraft comprises rotating the one or more barbs past the deployed position in a direction toward the target spacecraft.
