Abstract
A system and method for improving the flight control and efficiency of an aerial vehicle. Many embodiments are directed to a rotor-shroud assembly system where a plurality of rotor blades are connected to the internal side of a shroud and are set up to pivot through the use of a pitching mechanism. The entire assembly is configured to rotate when attached to a motor.
Claims16
A rotor-shroud assembly comprising:
- a central hub configured to rotate about a central axis,
- a plurality of rotor blades circumferentially disposed on and moveably connected to the central hub, wherein each of the plurality of rotor blades has a first end pivotably connected to the central hub and an elongated body extending outwardly from central hub towards a second end,
- wherein the second end is pivotably connected to a shroud that circumscribes the plurality of rotor blades, wherein each of the plurality of rotor blades can rotate about an elongated axis extending between the first and second end and perpendicular to the pivot connection with the shroud and
- wherein the shroud is configured to rotate with the rotation of the rotors about the central axis.
