Abstract

A modular fuselage for an unmanned aerial vehicle (UAV) includes a battery module, an avionics module, and a mission payload module. The battery module houses a battery to power the UAV. The avionics module houses flight control circuitry of the UAV. The mission payload module houses equipment associated with a mission of the UAV. The battery module, the avionics module, and the mission payload module are detachable from each other and mechanically securable to each other to contiguously form at least a portion of the modular fuselage of the UAV.

First claim

What is claimed is:

1. A modular fuselage for an unmanned aerial vehicle (UAV), comprising:
a battery module for housing a battery to power the UAV;
an avionics module that houses flight control circuitry of the UAV; and
a mission payload module that houses equipment associated with a mission of the UAV,
wherein the battery module, the avionics module, and the mission payload module are detachable from each other and mechanically securable to each other to contiguously form at least a portion of the modular fuselage of the UAV,
wherein undersides of the battery module, the avionics module, and the mission payload module have mating curvatures that collectively form an external surface of the modular fuselage when mechanically secured to each other,
wherein the mission payload module comprises a middle section of the modular fuselage disposed between the battery module and the avionics module,
wherein the battery module comprise a fore section of the modular fuselage and a detachable tensile support rod connects a distal portion of the battery module to the mission payload module to carry loads from the battery module to the mission payload module,
wherein the mission payload module includes a spar mounting bracket for securing a wing spar to the modular fuselage and wherein the detachable tensile support rod connects between the spar mounting bracket and the distal portion of the battery module to carry the loads from the battery module to the wing spar when connected via the spar mounting bracket.

2. The modular fuselage of claim 1 , wherein the battery module, the avionics module, and the mission payload module are shaped to secure to each other to form the modular fuselage, and wherein the battery module, the avionics module, and the mission payload module are arrangeable into the modular fuselage separate from and prior to attaching a wing of the UAV to the modular fuselage.

3. The modular fuselage of claim 1 , wherein the mission payload module includes a mounting bracket for securing a wing assembly of the UAV to the modular fuselage.

4. The modular fuselage of claim 3 , wherein the avionics module comprises an aft section of the modular fuselage.

5. The modular fuselage of claim 1 , wherein the mission payload module comprises one of: a payload actuator for holding and releasing an externally attached payload, a camera equipment holder, a sensor equipment holder, or an additional battery holder.

6. The modular fuselage of claim 1 , wherein the modular fuselage further includes:
a fuselage cover that extends over a top portion and along first side portions of the battery module, along second side portions of the mission payload module, and along third side portions of the avionics module,
wherein a bottom skid plate of the avionics module forms channels with the third side portions of the avionics module into which tongue portions of the fuselage cover are secured.

7. The modular fuselage of claim 1 , wherein the battery module, the avionics module, and the mission payload module are mechanically securable to each other using mechanical fasteners.

8. The modular fuselage of claim 7 , wherein the avionics module includes a first set of fastener holes that align with a second set of fastener holes on an underside of the mission payload module when the avionics module is secured to the mission payload module with first and second mechanical fasteners that insert into the first and second sets of fastener holes from the underside of the mission payload module, and wherein the first and second mechanical fasteners also hold a top cover of the avionics module in place over the avionics module.

9. The modular fuselage of claim 7 , wherein the avionics module includes a torsion box including a roll shear wall and a pitch shear wall that provide rolling and pitching shear strength to the mission payload module through a subset of the mechanical fasteners that secure the avionics module to the mission payload module.

10. An unmanned aerial vehicle (UAV), comprising:
a wing assembly to provide lift;
a plurality of boom assemblies that secure to the wing assembly, each of the boom assemblies including a plurality of propellers to provide vertical propulsion; and
a modular fuselage mountable to the wing assembly, the modular fuselage including:
a battery module for housing a battery to power the UAV;
an avionics module that houses flight control circuitry of the UAV; and
a mission payload module that houses equipment associated with a mission of the UAV,

wherein the battery module, the avionics module, and the mission payload module are detachable from each other and mechanically securable to each other to contiguously form at least a portion of the modular fuselage of the UAV,
wherein the battery module, the avionics module, and the mission payload module each form a portion of an external surface of the modular fuselage when mechanically secured to each other.

11. The UAV of claim 10 , wherein the battery module, the avionics module, and the mission payload module are shaped to secure to each other to form the modular fuselage separate from being mechanically secured to the wing assembly or the boom assemblies.

12. The UAV of claim 10 , wherein undersides of the battery module, the avionics module, and the mission payload module form the external surface of the modular fuselage when mechanically secured to each other.

13. The UAV of claim 10 , wherein the mission payload module comprises a middle section of the modular fuselage and wherein the wing assembly mounts to the mission payload module.

14. The UAV of claim 13 , wherein the battery module comprises a fore section of the modular fuselage and the avionics module comprises an aft section of the modular fuselage.

15. The UAV of claim 13 , wherein the wing assembly includes a wing spar disposed within a wing foil that mounts to a spar mounting bracket on the mission payload module and wherein the battery module includes a detachable tensile support rod that connects between the spar mounting bracket and a distal portion of the battery module to carry loads from the battery module to the wing spar.

16. The UAV of claim 10 , wherein the mission payload module comprises one of: a payload actuator for holding and releasing an externally attached payload, camera equipment holder, a sensor equipment holder, or an additional battery holder.

17. The UAV of claim 10 , wherein the modular fuselage further includes:
a fuselage cover that extends over a top portion and along first side portions of the battery module, along second side portions of the mission payload module, and along third side portions of the avionics module,
wherein a bottom skid plate and a top cover of the avionics module form channels with the third side portions of the avionics module into which tongue portions of the fuselage cover and tongue portions of a wing foil of the wing assembly are secured.

18. The UAV of claim 10 , wherein the battery module, the avionics module, and the mission payload module are mechanically securable to each other using mechanical fasteners.

19. The UAV of claim 18 , wherein the avionics module includes a first set of fastener holes that align with a second set of fastener holes on an underside of the mission payload module when the avionics module is secured to the mission payload module with first and second mechanical fasteners that insert into the first and second sets of fastener holes from the underside of the mission payload module, and wherein the first and second mechanica
