A rotor arrangement for an aircraft comprising two coaxially counter-rotatable rotators, each rotor being journaled freely rotatable about an imaginary axis of rotation common to both rotors on or through a fuselage part or a support member, each fuselage part or support member being either rigidly connected to or journaled on the fuselage, each rotor together with the other respective rotor or with the component part of the support member or fuselage part supporting the first mentioned rotor constituting an integral part of an electromotor by forming th...
An aircraft comprising, a fuselage, two coaxially counter-rotatable rotors, blade mounts carried by said rotors, each rotor being journaled to said fuselage about an imaginary axis of rotation common to both rotors, each of said rotors carrying poles and cooperating with a counteracting pole carrying member to form at least one electromotor, a current generator electrically connected to a pole carrying member of at least one rotor so that upon production of a frequency current a reciprocal field effect is created between counteractive members to cause co...
