2. The recovery and deployment pylon of claim 1 , further comprising a movable ejector configured to extend away from the housing, wherein the ejector is configured to exert a force on the target aircraft upon activation of the ejector to cause the target aircraft to move away from the pylon when the target aircraft is positioned within a predetermined distance of the recovery and deployment pylon.
3. The recovery and deployment pylon of claim 2 , wherein the ejector comprises an elongate member that is configured to move axially between a first position in which the ejector is retracted and a second position in which the ejector is extended.
4. The recovery and deployment pylon of claim 1 , further comprising a first shock absorber extending away from the housing in an operable state, the first shock absorber configured to contact an upper surface of the target aircraft as the target aircraft is brought into engagement with the pylon.
5. The recovery and deployment pylon of claim 1 , comprising a second latching mechanism configured to selectively engage with a second lug of the target aircraft when the target aircraft is in the first position.
6. The recovery and deployment pylon of claim 1 , further comprising a first alignment member coupled with the housing on an underside surface of the housing, the first alignment member projecting away from the underside surface of the housing in a downward direction and configured to laterally constrain a target aircraft engaged with the pylon.
7. The recovery and deployment pylon of claim 1 , further comprising one or more sensors configured to determine when the target aircraft is in the first position.
8. The recovery and deployment pylon of claim 1 , comprising an upper sheave supported within the housing, wherein the towline extends from the fleet pulleys and around the upper sheave.
9. The recovery and deployment pylon of claim 1 , wherein the plurality of fleet pulleys comprises two pulleys oriented approximately horizontally.
10. The recovery and deployment pylon of claim 1 , wherein the motorized winch is laterally oriented such that an axis of rotation is oriented in a lateral direction that is perpendicular to a longitudinal axis of the recovery and deployment pylon.
11. The recovery and deployment pylon of claim 1 , wherein the motorized winch is longitudinally oriented.
12. The recovery and deployment pylon of claim 1 , further comprising:
a forward bulkhead;
an aft bulkhead;
a connecting member; and
a rack unit,
wherein the forward bulkhead and the aft bulkhead are configured to be mechanically coupled to the host aircraft,
wherein the connecting member is mechanically coupled to the forward bulkhead and the aft bulkhead, and
wherein the rack unit is mechanically coupled to at least one of the forward bulkhead, the aft bulkhead, or the connecting member.
13. A system including the pylon of claim 1 and a capture mechanism configured to be coupled with a target aircraft, the capture mechanism configured to move between a first state in which the capture mechanism is configured to secure the fitting with the capture mechanism such that the target aircraft can be pulled toward the pylon when the towline is reeled in and a second state in which the capture mechanism is configured to release the fitting from the capture mechanism.
14. The system of claim 13 , comprising a fitting release hatch configured to selectively open to release the fitting from the capture mechanism.
15. The system of claim 14 , wherein the capture mechanism of the target aircraft comprises one or more flaps configured to deploy and stow, wherein the one or more flaps deploy to define an opening through which the towline is received, and wherein the flaps stow to guide the fitting into a recess of the target aircraft.
16. The system of claim 13 , wherein a rack unit is shaped to provide a central cavity such that the towline can be released through a central portion of the pylon.
17. A recovery and deployment pylon for recovering and relaunching a target aircraft, the pylon comprising:
a housing configured to be coupled with a host aircraft;
a motorized winch within the housing;
a towline coupled with the motorized winch and configured to be selectively paid out and reeled in using the motorized winch;
a plurality of fleet pulleys supported within the housing, wherein the towline extends from the motorized winch through the plurality of fleet pulleys;
a fitting coupled with the towline, the fitting having a width that is larger than a width of the towline; and
a movable ejector configured to extend away from the housing, wherein the ejector is configured to exert a force on the target aircraft upon activation of the ejector to cause the target aircraft to move away from the pylon when the target aircraft is positioned within a predetermined distance of the recovery and deployment pylon;
wherein the motorized winch further comprises a cartridge through which the towline extends, and
wherein the cartridge is movable along an axle such that a portion of the towline between the motorized winch and the plurality of fleet pulleys may sweep a total angle of up to thirty degrees.
18. A method of servicing a target aircraft in flight using a recovery and deployment pylon coupled with a host aircraft, comprising:
extending a towline from the recovery and deployment pylon, the towline extending from a winch through a plurality of fleet pulleys supported within the recovery and deployment pylon, the towline extending through a cartridge of the winch, wherein the cartridge is movable along an axle such that a portion of the towline between the winch and the plurality of fleet pulleys is configured to sweep a total angle of up to thirty degrees;
coupling the towline with the target aircraft;
reeling in the towline to move the target aircraft to a predetermined position relative to the recovery and deployment pylon;
latching the target aircraft to the recovery and deployment pylon by engaging a first lug on the target aircraft with a first latching mechanism of the recovery and deployment pylon;
servicing the target aircraft;
decoupling the towline from the target aircraft; and
releasing the target aircraft from the recovery and deployment pylon.
19. The method of claim 18 , wherein servicing the target aircraft comprises rearming, refueling, and/or providing power to the target aircraft.
20. The method of claim 18 , wherein releasing the target aircraft from the recovery and deployment pylon comprises actuating an ejector mechanism to exert a force on the target aircraft that causes the target aircraft to move away from the recovery and deployment pylon.
