A multi-mode unmanned aerial vehicle, comprising:
- an elongated fuselage having a front end, a rear end with a curved guide slot, a right side, a left side, and a wing-in-ground (WIG) effect bottom;
- a right-fixed wing extending from the right side of the elongated fuselage;
- a right tilt wing attached at a first side to a free end of the right fixed wing, the right tilt wing being rotatable in a range of 0-135 degrees about a lateral axis of the multi-mode unmanned aerial vehicle;
- a right duct attached to a second side of the right tilt wing;
- a right winglet attached to the right duct opposite to the right tilt wing;
- a left-fixed wing extending from the left side of the elongated fuselage;
- a left tilt wing attached at a first side to a free end of the left fixed wing, the left tilt wing being rotatable in a range of 0-135 degrees about the lateral axis of the multi-mode unmanned aerial vehicle;
- a left duct attached to a second side of the left tilt wing;
- a left winglet attached to the left duct opposite to the left tilt wing;
- a tilt tail located within the curved guide slot at the rear end of the elongated fuselage, the tilt tail being rotatable in a range of 0-90 degrees about the lateral axis of the multi-mode unmanned aerial vehicle and within the curved guide slot, wherein the tilt tail includes a vertical stabilizer, a right horizontal stabilizer, and a left horizontal stabilizer;
- a rear duct attached to the tilt tail;
- a tilting mechanism including
- a first set of servo actuators connected via a bevel gear group to a right and left set of horizontally-oriented shafts integrated with the right tilt wing and the left tilt wing, respectively,
- a set of pulleys connected to the right and left set of horizontally-oriented shafts, and
- a second set of servo actuators connected to a rear shaft integrated with the tilt tail;
- and
- an integrated autonomous flight control system including processing circuitry configured to control flight and navigation of the multi-mode unmanned aerial vehicle and to control the tilting mechanism.
