Unmanned aerial vehicles with interchangeable wing modules

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.
