Abstract

A launch includes a frame including a platform defining a slot designed to slideably receive a rudder of a fixed-wing unmanned aerial vehicle. The launch includes two drive wheels rotatably supported by the frame and defining a space between each other. The space is open to the slot and designed to receive the rudder. The launch includes at least one variable speed drive wheel motor supported by the frame and operatively engaged with the drive wheels.

First claim

What is claimed is:

1. An unmanned vehicle launch comprising:
a frame including a platform defining a slot designed to slideably receive a rudder of a fixed-wing unmanned aerial vehicle;
two drive wheels rotatably supported by the frame and defining a space between each other, the space being open to the slot and designed to receive the rudder;
at least one variable speed drive wheel motor supported by the frame and operatively engaged with the drive wheels;
wind speed sensor;
a wind direction sensor; and
a computer in communication with the variable speed drive wheel motor, the wind speed sensor, and the wind direction sensor, the computer programmed to receive measurements of the wind speed relative to the launch from the wind speed sensor and wind direction relative to the launch from the wind direction sensor and programmed to drive the variable speed drive wheel motor at various speeds based at least on the measurements of the wind speed and wind direction.

2. The unmanned vehicle launch as set forth in claim 1 , wherein the computer is programmed to receive a measurement of a vehicle heading and is programmed to control the speed of the at least one drive motor based at least on the measurement of the vehicle heading.

3. The unmanned vehicle launch as set forth in claim 2 , further comprising a base supporting the frame and at least one position motor configured to adjust at least one of rotation of the platform relative to the base, height of the platform relative to the base, and launch angle of the platform relative to the base, and the computer is programmed to adjust the at least one position motor based at least on the measurement of the wind speed and wind direction relative to the launch and based at least on the measurement of the vehicle heading.

4. The unmanned vehicle launch as set forth in claim 1 , further comprising at least one sensor configured to measure wind speed and wind direction relative to the launch.

5. The unmanned vehicle launch as set forth in claim 4 , further comprising a base supporting the frame, wherein the at least one sensor is supported on the base.

6. The unmanned vehicle launch as set forth in claim 4 , wherein the at least one sensor is a wind vane, an airspeed sensor on the wind vane, and a magnetometer on the wind vane.

7. The unmanned vehicle launch as set forth in claim 1 , further comprising a base supporting the frame and at least one position motor configured to adjust at least one of rotation of the platform relative to the base, height of the platform relative to the base, and launch angle of the platform relative to the base.

8. The unmanned vehicle launch as set forth in claim 7 , wherein the computer is programmed to adjust the at least one position motor based at least on the measurements of the wind speed and wind direction relative to the launch.

9. The unmanned vehicle launch as set forth in claim 1 , wherein the computer is programmed to control a propeller of the fixed-wing unmanned aerial vehicle to move the rudder into engagement with the drive wheel.

10. The unmanned vehicle launch as set forth in claim 1 , further comprising a base supporting the frame, wherein the platform is moveable relative to the base in three degrees of freedom.

11. The unmanned vehicle launch as set forth in claim 1 , further comprising a base supporting the frame, and a lifting mechanism between the base and the platform, the lifting mechanism being designed to translationally move the platform relative to the base.

12. The unmanned vehicle launch as set forth in claim 1 , further comprising a base supporting the frame, and a rotating mechanism between the base and the platform, the rotating mechanism being designed to rotate the platform relative to the base.

13. The unmanned vehicle launch as set forth in claim 1 , further comprising a base supporting the frame, and a pivoting mechanism between the base and the platform, the pivoting mechanism being designed to pivot the platform relative to the base.

14. A launch kit comprising:
a frame having a platform defining a slot;
a rudder for a fixed-wing unmanned aerial vehicle, the rudder being slideably engageable with the slot;
two drive wheels rotatably supported by the frame and engageable with the rudder;
at least one variable speed motor supported by the frame and operatively engaged with the drive wheels;
a wind speed sensor;
a wind direction sensor; and
a computer in communication with the variable speed motor, the wind speed sensor, and the wind direction sensor, the computer programmed to receive measurements of wind speed from the wind speed sensor and wind direction from the wind direction sensor and programmed to drive the variable speed motor at various speeds based at least on the measurements of the wind speed and wind direction.
