Tworotor
Tworotor is a term used to describe any device or system that employs two rotors as its primary moving elements. It is not tied to a single design, but rather denotes a two-rotor configuration across different domains, including mechanical engineering, aerospace, and cryptography.
In mechanical engineering, a two-rotor arrangement may occur in rotary engines and related mechanisms. Two rotors
In rotorcraft and propulsion, two-rotor configurations arise as twin-rotor systems, including coaxial arrangements where two rotors
In cryptography and historical cipher devices, two-rotor machines used sequential substitution from two rotating disks to
