Abstract

Various embodiments of the present disclosure provide a helicopter-mediated system and method for launching and retrieving an aircraft capable of long-distance efficient cruising flight from a small space without the use of a long runway.

First claim

The invention is claimed as follows:

1. A system for retrieving a fixed-wing aircraft from wing-borne flight, the fixed-wing aircraft having a hook attached to a wing of the fixed-wing aircraft, the system comprising:
a flexible member attachable to a copter separate from the fixed-wing aircraft, the flexible member configured to be engaged by the hook of the fixed-wing aircraft such that the hook of the fixed-wing aircraft engages the flexible member to connect the fixed-wing aircraft to the flexible member; and
an anchor device comprising a retracting device attachable to the flexible member such that a first portion of the flexible member extends from the anchor device to the copter when the copter is flying,
wherein the retracting device is configured to, when the flexible member is attached to the retracting device and extending from the anchor device, impose a retracting force on the flexible member, and
wherein the retracting device is further configured to, when the flexible member is attached to the retracting device, pay out a second portion of the flexible member when a first force greater than the retracting force is imposed on the flexible member in a direction away from the retracting device.

2. The system of claim 1 , further comprising a control system and a navigation device, wherein the navigation device is configured to determine a geographical location of the anchor device and to transmit the determined geographical location of the anchor device to the control system.

3. The system of claim 2 , wherein the control system is configured to use the determined geographical location of the anchor device to cause the copter to station-keep relative to the anchor device.

4. The system of claim 1 , further comprising the copter.

5. The system of claim 1 , wherein the retracting device is configured to impose a continuous retracting force on the flexible member while the copter is flying.

6. The system of claim 1 , wherein
in a first state, the retracting device is configured to, when the flexible member is attached to the retracting device and extending vertically from the anchor device, impose a retracting force on the flexible member, and
in a second state, the retracting device is configured to, when the flexible member is attached to the retracting device and extending at an angle less than vertically from the anchor device, enable pay out of the flexible capture member.

7. A system for retrieving a fixed-wing aircraft from wing-borne flight, the fixed-wing aircraft having a hook attached to a wing of the fixed-wing aircraft, the system comprising:
a flexible member attachable to a copter separate from the fixed-wing aircraft, the flexible member configured to be engaged by the hook of the fixed-wing aircraft such that the hook of the fixed-wing aircraft engages the flexible member to connect the fixed-wing aircraft to the flexible member; and
an anchor device comprising a retracting device attachable to the flexible member such that a first portion of the flexible member extends from the anchor device to the copter when the copter is flying,
wherein the retracting device is configured to, when the flexible member is attached to the retracting device and extending from the anchor device, impose a retracting force on the flexible member, and
wherein the retracting device is further configured to, when the flexible member is attached to the retracting device, retract at least part of a second portion of the flexible member when a second force less than the retracting force is imposed on the flexible member in a direction away from the retracting device.

8. The system of claim 7 , wherein the retracting device is further configured to, when the flexible member is attached to the retracting device, pay out the second portion of the flexible member when a first force greater than the retracting force is imposed on the flexible member in a direction away from the retracting device.

9. An anchor device for retrieving a fixed-wing aircraft from wing-borne flight, the fixed-wing aircraft having a hook attached to a wing of the fixed-wing aircraft, the anchor device comprising:
a base; and
a retracting device supported by the base and configured to, when a flexible member is attached to the retracting device:
pay out a portion of the flexible member from the retracting device when a first force greater than the retracting force is imposed on the retracting device via the flexible member by a flying copter in a direction away from the retracting device, and
retract at least part of the portion of the flexible member into the retracting device when a second force less than the retracting force is imposed on the flexible member by the flying copter in a direction away from the retracting device,
wherein the flying copter is separate from the fixed-wing aircraft, and
wherein the flexible member is configured to be engaged by the hook of the fixed-wing aircraft such that the hook of the fixed-wing aircraft engages the flexible member to connect the fixed-wing aircraft to the flexible member.
