Modular unmanned aerial system

1. A modular unmanned aerial system comprising:

a chassis for attaching components of the modular unmanned aerial system;

one or more rotary wings, each of the one or more rotary wings drivable by a respective motor;

a central controller for controlling operation of the modular unmanned aerial system;

a plurality of interchangeable modules selected from the group consisting of a payload module carrying a charge of a fuel/oxidizer mixture, a firearm cartridge module, an optical module, a scanning module, a large caliber munitions module, and a hazard sensing module;

a first docking interface attached to the chassis and adapted for removably and interchangeably attaching each of the plurality of interchangeable modules; and

a second docking interface attached to the chassis and adapted for removably attaching a first battery module, the first battery module interchangeable with a like battery module when the first battery module is depleted.

2. The modular unmanned aerial system of claim 1 , wherein the first docking interface includes a receptacle on an underside of said chassis configured to removably receive a complementary connecting member on the plurality of interchangeable modules.

3. The modular unmanned aerial system of claim 1 , wherein the first docking interface is disposed at the center of gravity of the modular unmanned aerial system.

4. The modular unmanned aerial system of claim 1 , further comprising an electrical interface for operably electrically connecting the first battery module to an attached one of the plurality interchangeable modules.

5. The modular unmanned aerial system of claim 1 , further comprising an electrical interface for operably electrically connecting the first battery module to an electrical circuit in the chassis.

6. The modular unmanned aerial system of claim 1 , wherein said central controller is configured to operably communicate with the plurality of interchangeable modules when attached to the first docking interface.

7. The modular unmanned aerial system of claim 1 , wherein the optical module includes a camera attached to a gimbal rotatable about a yaw axis in the modular unmanned aerial system.

8. The modular unmanned aerial system of claim 1 , wherein the payload module includes thermite.

9. The modular unmanned aerial system of claim 1 , wherein the firearm cartridge module includes a plurality of ammunition rounds.

10. The modular unmanned aerial system of claim 1 , wherein the central controller includes a flight control system.

11. The modular unmanned aerial system of claim 10 , wherein the plurality of interchangeable modules includes the scanning module and wherein the flight control system is configured to be communicatively coupled with the scanning module.

12. The modular unmanned aerial system of claim 10 , wherein the flight control system is configured to operate in a GPS-denied environment.

13. The modular unmanned aerial system of claim 1 , wherein the large caliber munitions module includes one or more large caliber munitions.

14. The modular unmanned aerial system of claim 13 , wherein the one or more large caliber munitions is selected from the group consisting of a grenade, a rocket propelled grenade, and precision guided munition.

15. The modular unmanned aerial system of claim 1 , wherein the large caliber munitions module forms a nacelle hardpoint.
