Abstract

A modular mounting structure is described which allows for the easy installation and removal of various payloads from a vehicle structure. An embedded electrical bus feature further supports the installation of the various payloads into the vehicle structure.

Claims

1. A mounting system for the removable attachment of a payload to an unmanned air vehicle, the mounting system comprising:

a pair of lower rails disposed adjacent a payload area of the unmanned air vehicle, said lower rails configured to interface with the payload; and

a pair of upper rails disposed adjacent the payload area, said upper rails spaced apart from said lower rails, said upper rails configured to interface with the payload;

wherein the unmanned air vehicle includes an aircraft structure having a left side and a right side, the aircraft structure defining an inner cavity and a payload bay;

wherein the pair of lower rails includes (i) a left lower rail disposed within the inner cavity along the left side of the aircraft structure and (ii) a right lower rail disposed within the inner cavity along the right side of the aircraft structure;

wherein the pair of upper rails includes (i) a left upper rail disposed within the inner cavity along the left side of the aircraft structure and (ii) a right upper rail disposed within the inner cavity along the right side of the aircraft structure;

wherein the pair of lower rails are closer to the payload bay than the pair of upper rails;

wherein the rails are arranged to receive delivery of the payload from a location above the unmanned air vehicle, the payload interfacing with the rails upon being dropped in from above the unmanned air vehicle.

2. The mounting system of claim 1, wherein said lower rails and said upper rails extend along a longitudinal axis of the unmanned air vehicle.

3. The mounting system of claim 1, wherein said lower rails and said upper rails are symmetrically spaced about a longitudinal axis of the unmanned air vehicle.

4. The mounting system of claim 1, wherein said lower rails and said upper rails are integrally formed into the aircraft structure of the unmanned air vehicle.

5. The mounting system of claim 1, further comprising:

a plurality of mounting devices that engages and locks onto said upper and lower rails, each mounting device being constructed and arranged to attach the payload to one of the upper and lower rails.

6. The mounting system of claim 1, further comprising:

an electrical bus embedded into the aircraft structure of the unmanned air vehicle, said electrical bus being constructed and arranged to electrically interface with the payload.

7. The mounting system of claim 6, further comprising:

a connector plate in electrical communication with said electrical bus, the connector plate including an electrical connector constructed and arranged to attach to an electrical cable of the payload.

8. The mounting system of claim 1, wherein the aircraft structure further defines a longitudinal axis;

and

wherein each lower rail and each upper rail extends along the longitudinal axis and is integrally formed into the aircraft structure, the pair of lower rails and the pair of upper rails being parallel to each other.

9. The mounting system of claim 8, further comprising:

an electrical bus which extends along the longitudinal axis and which is parallel to the pair of lower rails and the pair of upper rails, the electrical bus electrically interfacing the unmanned air vehicle to a set of payload components.

10. The mounting system of claim 9, further comprising:

a connector plate which affixes to the aircraft structure, the connector plate interconnecting the electrical bus to at least one payload component.

11. The mounting system of claim 1, further comprising:

mounting devices that mount to the pair of lower rails and the pair of upper rails, each mounting device including (i) a mount structure for physical communication with the payload and (ii) a threaded fastener which fastens the mount structure to a respective rail when turned in a first direction and releases the mount structure from the respective rail when turned in a second direction opposite the first direction.

12. The mounting system of claim 11 wherein each rail has a uniform cross-section;

and

wherein each mounting device is constructed and arranged to be (i) placed at any location along a longitudinal length of a respective rail and (ii) mounted to that location.

13. The mounting system of claim 1, further comprising:

a set of panel members which, in combination with the payload, forms a seal to cover the payload bay.

18. The mounting system of claim 1, further comprising:

a structure that (i) positions the lower rails a first distance apart from each other and (ii) positions the upper rails a second distance apart from each other and above the lower rails, the first distance being smaller than the second distance.

19. The mounting system of claim 1 wherein the aircraft structure of the unmanned air vehicle defines, as the payload bay, an opening at bottom location of the unmanned air vehicle;

and

wherein upon the payload being dropped in from above the unmanned air vehicle and attached to the rails, the rails support the payload so that the payload extends from the inner cavity to an external region beneath the inner cavity through the opening.

20. The mounting system of claim 19 wherein the aircraft structure of the unmanned air vehicle is constructed and arranged to receive a set of panels that completely seals the opening at the bottom location of unmanned air vehicle while the rails provide support for the payload.

14. An unmanned air vehicle, comprising:

an aircraft structure having a left side and a right side, the aircraft structure defining an inner cavity and a payload bay;

a pair of lower rails including (i) a left lower rail disposed within the inner cavity along the left side of the aircraft structure and (ii) a right lower rail disposed within the inner cavity along the right side of the aircraft structure;

payload mounting devices which individually fasten to the rails at locations along the rails to attach a payload to the unmanned air vehicle;

wherein the rails are arranged to receive delivery of the payload from a location above the unmanned air vehicle, the payload interfacing with the rails upon being dropped in from above the unmanned air vehicle.

15. The unmanned air vehicle of claim 14 wherein each mounting device includes (i) a mount structure which physically communicates with the payload and (ii) a threaded fastener which fastens the mount structure to a respective rail when turned in a first direction and releases the mount structure from the respective rail when turned in a second direction opposite the first direction;

wherein each rail has a uniform cross-section; and

wherein each mounting device is placeable at any location along a longitudinal length of a respective rail and mounted to that location.

16. The unmanned air vehicle of claim 15 wherein the aircraft structure further defines a longitudinal axis;
