Modular, In-Air, Multi-UAV Docking

A modular vertical takeoff and landing (VTOL) unmanned aerial system (UAS) is made up of multiple unmanned aerial vehicle (UAV) modules with uniform wingtips for tip-to-tip docking. Each UAV has twin booms with front and rear propellers and an empennage with a downward-mounted vertical rudder. All the propellers are tiltable for VTOL and the front ones are stowable for cruise efficiency.
