Abstract

An unmanned aerial vehicle has an airframe having first and second wing modules with first and second pylons extending therebetween. A thrust array is coupled to the airframe including two propulsion assemblies coupled to each of the first and second wings. An electric power system is operably associated with the thrust array and operable to provide power to each propulsion assembly. A flight control system is operably associated with the thrust array and operable to independently control the speed of each propulsion assembly. Each wing module is selected from a plurality of wing modules each having a respective function and each interchangeably couplable with the first and second pylons to enable the airframe to support the functions of the plurality of wing modules.

First claim

What is claimed is:

1. An unmanned aerial system comprising:
a modular airframe comprising:
a plurality of interchangeable upper wing modules each having a respective function and an airfoil cross section;
a lower wing module having an airfoil cross section; and
first and second pylons each having top and bottom ends, the plurality of interchangeable upper wing modules interchangeably mountable to the top ends of the pylons to enable the airframe to support the respective function of a selected one of the plurality of interchangeable upper wing modules, the lower wing module mounted to the bottom ends of the pylons;
a thrust array coupled to the airframe including first and second propulsion assemblies coupled to the selected interchangeable upper wing module and third and fourth propulsion assemblies coupled to the lower wing module;
an electric power system operably associated with the thrust array and operable to provide power to each propulsion assembly; and
a flight control system operably associated with the thrust array and operable to independently control the speed of each propulsion assembly;
wherein, each of the plurality of interchangeable upper wing modules comprises a pylon mounting interface configured to form pivot joints with the top ends of the pylons to enable rotation of the pylons relative to the selected interchangeable upper wing module; and
wherein, in a flight configuration, the selected interchangeable upper wing module is parallel with the lower wing module and the first pylon is parallel with the second pylon such that the airframe has a rectangular cross section.

2. The unmanned aerial system as recited in claim 1 wherein the plurality of interchangeable upper wing modules comprise an autonomous navigation system wing module including a navigation system.

3. The unmanned aerial system as recited in claim 1 wherein the plurality of interchangeable upper wing modules comprise a remote navigation system wing module including a navigation system.

6. The unmanned aerial system as recited in claim 1 wherein the plurality of interchangeable upper wing modules comprise a cargo storage wing module forming a storage bay.

7. The unmanned aerial system as recited in claim 1 wherein the plurality of interchangeable upper wing modules comprise a flight control system and electric power system wing module including a flight control computer and one or more batteries.

8. The unmanned aerial system as recited in claim 1 wherein the pivot joints comprise pivot locks configured to selectively lock rotation of the pylons relative to the selected interchangeable upper wing module.

9. An unmanned aerial system comprising:
a modular airframe comprising:
an upper wing module having an airfoil cross section;
a plurality of interchangeable lower wing modules each having a respective function and an airfoil cross section; and
first and second pylons each having top and bottom ends, the upper wing module mounted to the top ends of the pylons, the plurality of interchangeable lower wing modules interchangeably mountable to the bottom ends of the pylons to enable the airframe to support the respective function of a selected one of the plurality of interchangeable lower wing modules;
a thrust array coupled to the airframe including first and second propulsion assemblies coupled to the upper wing module and third and fourth propulsion assemblies coupled to the selected interchangeable lower wing module;
an electric power system operably associated with the thrust array and operable to provide power to each propulsion assembly; and
a flight control system operably associated with the thrust array and operable to independently control the speed of each propulsion assembly;
wherein, each of the plurality of interchangeable lower wing modules comprises a pylon mounting interface configured to form pivot joints with the bottom ends of the pylons to enable rotation of the pylons relative to the selected interchangeable lower wing module; and
wherein, in a flight configuration, the upper wing module is parallel with the selected interchangeable lower wing module and the first pylon is parallel with the second pylon such that the airframe has a rectangular cross section.

10. The unmanned aerial system as recited in claim 9 wherein the plurality of interchangeable lower wing modules comprise a remote navigation system wing module including a navigation system.
