Abstract

A control system for portable control of a rotary-wing aircraft includes a portable, hand-held, control device executing a control application, the control device operating in a loaded mode when a load is attached to the rotary-wing aircraft and an unloaded mode when no load is attached to the rotary-wing aircraft, the control device presenting command icons in response to being in loaded mode and unloaded mode; a vehicle management system in the rotary-wing aircraft; a sensor package on the rotary-wing aircraft; and a communication system providing communications between the control device and the rotary-wing aircraft, vehicle management system and sensor package; wherein the control device communicates commands to the vehicle management system to implement loading and unloading of the rotary-wing aircraft.

Claims

1. A control system for portable control of a rotary-wing aircraft, the control system comprising:

a portable, hand-held, control device executing a control application, the control device operating in a loaded mode when a load is attached to the rotary-wing aircraft and an unloaded mode when no load is attached to the rotary-wing aircraft, the control device presenting command icons in response to being in loaded mode and unloaded mode;

a vehicle management system in the rotary-wing aircraft;

a sensor package on the rotary-wing aircraft; and

a communication system providing communications between the control device and the rotary-wing aircraft, vehicle management system and sensor package;

wherein the control device communicates commands to the vehicle management system to implement loading and unloading of the rotary-wing aircraft;

wherein the control device executes a receive aircraft mode, hover mode, en-route mode and ground mode, wherein in the receive aircraft mode, the control device presents a list of aircraft within range of the control device and available for control by the control device, wherein in the hover mode, the control device presents icons to control the rotary-wing aircraft in a hover flight, wherein in the en route mode, the control device commands the rotary-wing aircraft to follow a preloaded flight plan and wherein in the ground mode, the control device commands the rotary-wing aircraft to land.

2. The control system of claim 1 wherein:

the communication system includes a wireless router in communication with the control device and a data link coupled to the wireless router;

the rotary-wing aircraft including a second data link in communication with the data link and coupled to the vehicle management system.

3. The control system of claim 1 wherein:

the communication system includes a cellular network in communication with the control device;

the rotary-wing aircraft including a cellular network modem in communication with the cellular network and coupled to the vehicle management system.

4. The control system of claim 1 wherein:

the communication system includes a data link coupled directly to the control device;

the rotary-wing aircraft including a second data link in communication with the data link and coupled to the vehicle management system.

5. The control system of claim 1 wherein:

the communication system includes a communication element within the control device;

the rotary-wing aircraft including a wireless router in communication with the communication element and coupled to the vehicle management system.

6. The control system of claim 1 wherein:

the hover mode includes a hover stationary mode and a hover manual mode.

7. The control system of claim 6 wherein:

in hover manual mode, the control device presents flight control icons for controlling the rotary-wing aircraft.

8. The control system of claim 7 wherein:

the flight control icons include altitude icons for controlling altitude of the rotary-wing aircraft.

9. The control system of claim 7 wherein:

the flight control icons include position icons for controlling position of the rotary-wing aircraft.

10. The control system of claim 7 wherein:

the flight control icons include heading icons for controlling a heading of the rotary-wing aircraft.

11. The control system of claim 6 wherein:

in hover manual mode, the control device presents command icons for initiating an operation by the rotary-wing aircraft.

12. The control system of claim 11 wherein:

in hover manual mode, the command icons include a cancel icon for terminating active command of the rotary-wing aircraft and transitioning to a stable state.

13. The control system of claim 11 wherein:

in hover manual mode, the command icons include a hover stationary icon for instructing the rotary-wing aircraft to hover at a fixed position.

14. The control system of claim 11 wherein:

in hover manual mode and no load detected attached to the rotary-wing aircraft, the command icons comprise a video/sensor icon for initiating display on the control device of real-time streaming footage from the rotary-wing aircraft for situational awareness, auto load, select load, center over load, hook load, and lift load.

15. The control system of claim 11 wherein:

in hover manual mode and a load detected attached to the rotary-wing aircraft, the command icons comprise a video/sensor icon for initiating display on the control device of real-time streaming footage from the rotary-wing aircraft for situational awareness, auto release load, place/lower load, release load, release sling, and drop load at point.

16. The control system of claim 1 wherein:

the ground mode includes a ground stationary mode and a ground manual mode.

17. The control system of claim 1 wherein:

in ground mode, the command icons comprise video/sensor icons for initiating display on the control device of real-time streaming footage from the rotary-wing aircraft for situational awareness.

18. The control system of claim 1 wherein:

in ground mode, the command icons include take off vertically to a predetermined altitude.

19. A portable, hand-held, control device for portable control of a rotary-wing aircraft, the control device comprising:

a display;

a wireless communication device for communications with at least one of a vehicle management system and a sensor package on the rotary-wing aircraft; and

a processor executing a control application, the control application operating in a loaded mode when a load is attached to the rotary-wing aircraft and an unloaded mode when no load is attached to the rotary-wing aircraft, the processor presenting command icons on the display in response to being in loaded mode and unloaded mode;

wherein the processor communicates commands from the wireless communication device to the vehicle management system to implement loading and unloading of the rotary-wing aircraft;

wherein the control device executes a receive aircraft mode, hover mode, en-route mode and ground mode, wherein in the receive aircraft mode, the control device presents a list of aircraft within range of the control device and available for control by the control device, wherein in the hover mode, the control device presents icons to control the rotary-wing aircraft in a hover flight, wherein in the en route mode, the control device commands the rotary-wing aircraft to follow a preloaded flight plan and wherein in the ground mode, the control device commands the rotary-wing aircraft to land.
