Boom assembly for aerial vehicle
An aerial vehicle includes a fuselage supporting a pair of wings, with each of wings having a pair of booms attached thereto. A tilt rotor is positioned at each of the forward ends of each of the booms, to provide the aerial vehicle with at least four tilt rotors. A fixed rotor is positioned at and secured to the aft (or trailing) ends of each of the booms, to provide the aerial vehicle with at least four fixed rotors.

each inner wing boom and outer wing boom comprising:
a tilt rotor mounted at or adjacent a forward end of the wing boom, the tilt rotor being operationally tiltable between a lift-generating position and a thrust-generating position;
a fixed rotor mounted at or adjacent a trailing end of the wing boom in a lift-generating position; and
an aerial vehicle control system operable to operate the aerial vehicle in a first mode in which all of the tilt rotors of the inner wing booms and the outer wing booms are operating in a thrust-generating position and all of the fixed rotors of the inner wing booms and the outer wing booms are not operating,
the aerial vehicle control system further being operable to operate the aerial vehicle in a second mode in which:

two of the four tilt rotors of e inner wing booms and the outer wing booms are not operating;
two of the four the fixed rotors of the inner zing booms and the outer wing booms are operating to generate lift; and
two of the four the fixed rotors of the inner wing booms and the outer zing booms are not operating.
2. The aerial vehicle of claim 1 , further comprising:
a tail having a starboard tail section and a port tail section; and
a rear fixed rotor mounted to the tail behind the starboard tail section and a port tail section.
3. The aerial vehicle of claim 1 , further comprising an electrical control system to control a rotational speed of each of the tilt rotors and the fixed rotors.
4. The aerial vehicle of claim 1 , further comprising a tilt control mechanism to control tilting of each of the tilt rotors.
5. The aerial vehicle of claim 1 , further comprising a battery system located in each of the port wing and the starboard wing, and electrically coupled to operatively provide electric power to electric motors of each of the tilt rotors and the fixed rotors.
6. A vertical takeoff and landing (VTOL) aerial vehicle comprising:
a fuselage;
a starboard wing secured to the fuselage;
a port wing secured to the fuselage;
an inner wing boom mounted to each of the starboard wing and the port wing;
an outer wing boom mounted to each of the starboard wing and the port wing;
each inner wing boom and outer wing boom comprising:
a tilt rotor mounted at or adjacent a forward end of the wing boom, the tilt rotor being operationally tiltable between a lift-generating position and a thrust-generating position;
a fixed rotor mounted at or adjacent a trailing end of the wing boom in a lift-generating position; and
an aerial vehicle control system operable to operate the aerial vehicle in an operating mode in which:
two of the four tilt rotors of the inner wing booms and the outer wing booms are operating it a thrust-generating position;
two of the four tilt rotors of the inner wing booms and the outer wing booms are not operating;
two of the four the fixed rotors of the inner wing booms and the outer wing booms are operating to generate lift; and
two of the four the fixed rotors of the inner wing booms and the outer wing booms are not operating.
7. The aerial vehicle of claim 6 , wherein during the operating mode:
the two tilt rotors of the outer wing booms are operating in a thrust-generating; and
the two fixed rotors of the inner wing booms are operating to generate lift.
8. The aerial vehicle of claim 7 , wherein during the operating mode, the two tilt rotors of the outer wing booms are not operating and are in a lift-generating position.
9. The aerial vehicle of claim 6 , wherein during the sec-end operating mode, the two of the four tilt rotors that are not operating are in a lift-generating position.
10. A method of operating a vertical takeoff and landing (VTOL) aerial vehicle, comprising:
