1. A rotary wing aircraft comprising:
- a body;
at least three rotor pairs connected to the body,each rotor pair comprising a horizontally oriented upper rotor having at least two rotor blades and a horizontally oriented lower rotor having at least two rotor blades,wherein during operation the upper rotor and lower rotor rotate around a shared rotor axis with the upper rotor rotating in a first direction in a first plane fixed relative to the rotor axis and the lower rotor rotating in an other direction in a second plane fixed relative to the rotor axis,and wherein the speed of rotation of each upper rotor can be varied independently from the lower rotors and the other upper rotors and the speed of rotation of each lower rotor can be varied independently from the upper rotors and the other lower rotors,whereby the aircraft can be made to ascend, descend, move forward, move backward, move side to side, yaw right and yaw left by only varying the relative speeds of rotations of the upper rotors and lower rotors.

Abstract
A rotary wing aircraft is provided having at least three rotor pairs. Each rotor pair has an upper rotor and a lower rotor. During operation, the upper rotor and lower rotor rotate around a shared rotor axis with the upper rotor rotating in a first direction and the lower rotor rotating in an opposite direction By independently controlling the speed of rotation of each upper rotor and each lower rotor the aircraft can be made to ascend, descend, move forward, move backward, move side to side, yaw right and yaw left by only varying the relative speeds of rotations of the upper rotors and lower rotors.
