Abstract

A vertical takeoff and landing aerial vehicle. A left linear support and a right linear support of the unmanned aerial vehicle are respectively provided with a first group of multiple lift propellers and a second group of lift propellers, and the aerial vehicle is provided with a left dorsal fin and a right dorsal fin. By arranging a plurality of lift propellers, a left dorsal fin, and a right dorsal fin on the vertical takeoff and landing aerial vehicle provided by the disclosure, the aerial vehicle is higher in stability in the flight process.

First claim

What is claimed is:

1. A VTOL (vertical take-off and landing) aerial drone comprising:
a left main wing and a right main wing;
a left secondary wing and a right secondary wing;
a main body coupled to the left main wing and the right main wing;
a left linear support coupled to the left main wing;
a right linear support coupled to right main wing;
wherein the left linear support has a first set of plurality of lifting propellers disposed thereon;
wherein the right linear support has a second set of plurality of lifting propellers disposed thereon;
a left dorsal fin disposed between any two of said first set of plurality of lifting propellers on the left linear support and is directly connected to the left main wing;
a right dorsal fin disposed between any two of said second set of plurality of lifting propellers on the right linear support and is directly connected to the right main wing; and
a left extra lifting propeller disposed on a distal end of the left dorsal fin, wherein a range of motion of the left extra lifting propellers at least partially overlaps with a range of motion of an adjacent lifting propeller in said first set of plurality of lifting propellers from a top view.

2. The aerial drone as recited in claim 1 further comprising at least one push propeller disposed at a rear end of the drone, each of said at least one push propeller has a rotation of axis in parallel with a longitudinal axis of the drone.

3. The aerial drone as recited in claim 2 , wherein one of said at least one push propeller is disposed at a rear end of the left linear support, and another one of said at least one push propeller is disposed at the end of the right linear support.

4. The aerial drone as recited in claim 3 , wherein each of said left dorsal fin and right dorsal fin has a lifting propeller disposed thereon.

5. The aerial drone as recited in claim 4 , wherein the lifting propeller disposed on each of said left dorsal fin and right dorsal fin is disposed on a top distal end of the left and right dorsal fins, respectively.

6. The aerial drone as recited in claim 4 , wherein a base of each of said left and right dorsal fins at least partially overlaps with said left and right main wings, respectively.

7. The aerial drone as recited in claim 4 , wherein each of said left and right dorsal fins has a rear-ward slant.

8. The aerial drone as recited in claim 4 , wherein the lifting propeller disposed on each of said left dorsal fin and right dorsal fin has a rotational coverage area that partially overlaps with a rotational coverage area of the lifting propeller disposed on the respective left and right linear supports immediately behind the respective dorsal fins.

9. A method of increasing a lifting power in a VTOL aerial drone without having to lengthen the aerial drone, the method comprising:
providing a left main wing and a right main wing on the drone;
providing a left secondary wing and a right secondary wing on the drone;
providing a main body coupled to the left main wing and the right main wing;
providing a left linear support coupled to the left main wing;
providing a right linear support coupled to the right main wing;
providing a first set of plurality of lifting propellers disposed on the left linear support;
providing a second set of plurality of lifting propellers disposed on the right linear support;
wherein the first set of plurality of lifting propellers and the second set of plurality of lifting propellers are disposed on a same first horizontal plane;
providing a left extra lifting propeller on the drone disposed on a second horizontal plane which is positioned higher than the first horizontal plane;
providing a right extra lifting propeller on the drone disposed on the second horizontal plane;
providing a left dorsal fin coupled to the left linear support, and the left extra lifting propeller is disposed on the top distal end of the left dorsal fin; and
wherein said left dorsal fin is disposed between any two of said first set of plurality of lifting propellers on the right linear support and is directly connected to the left main wing;
wherein said left extra lifting propeller has a range of motion at least partially overlaps with a range of motion of an adjacent lifting propeller in said first set of plurality of lifting propellers from a top view.

10. The method as recited in claim 9 , wherein from a top view, the first set of plurality of lifting propellers and the left extra lifting propeller are disposed co-linearly.

11. The method as recited in claim 10 , wherein from the top view, the left extra lifting propeller has a rotational coverage area that partially overlaps with a rotational coverage area of another lifting propeller in said first set of plurality of lifting propellers.

12. The method as recited in claim 11 further providing a push propeller disposed on a rear end of each of said left and right linear supports.

13. The method as recited in claim 11 , wherein there are no other lifting propellers besides the first and second sets of plurality of lifting propellers and the left and right extra lifting propellers.
