		ELECTROTOR ~ SloMo		To Primary Index

~ Rotor Driven by Direct Coupling to Slow Turning Motor ~

Objective:

Rotor and drive, for manned recreational rotorcraft that are, easy to fly, safe to fly, economical to produce, and require minimal maintenance.

Drawing of Principal Assembly:

Overview of Principal Assembly:

An aerodynamic rotor, which incorporates an electric motor, electronic controller, torque-pitch lift control and weight-shift cyclic control.

There is no gearbox between the motor and its aerodynamic rotor. The ratio between them is 1:1.

A torque-pitch coupling to provide faster responses to requested changes in thrust.

The weight shifting is to be assisted by aerodynamic blade twisting.

Applicable to the following twin-rotor configurations:

Bilateral: Intermeshing, Interleaving, and Side-by-side configurations.
Coaxial configuration: The coaxial may have one centrally located electric motor driving both rotors, should the efficiency of a single motor plus frame offset the aerodynamic inefficiency of the coaxial configuration.
