Abstract
A mechanism for steering and maneuvering an airborne body comprised of at least one actuator comprising an electric motor having a first axis, and a gear transmission for transmitting power from the electric motor to an angular motion axis of a fin that has an angular motion around a second axis to steer the airborne body, and wherein the mechanism is characterized in that the gear transmission is a beveloid gear type of transmission, an airborne body that comprised the mechanism, and a method for achieving the desired flight path of an airborne body implementing the mechanism.
Claims19
A mechanism for steering and maneuvering an airborne body comprising:
- a plurality of actuators arranged circumferentially about a longitudinal central axis of the airborne body, each actuator comprising:
- an electric motor having a first axis, and
- a gear transmission for transmitting power from the electric motor to an angular motion axis of a respective fin coupled to the actuator to steer the airborne body by aerodynamic maneuvering or Thrust Vector Control (TVC), wherein the gear transmission is a beveloid gear transmission, wherein the beveloid gear transmission transmits power from the electric motor to the fin, while the first axis of the motor is not parallel to the angular motion axis of the fin, but is positioned to create an angle between the two axes.
