Abstract

A VTOL aircraft is provided with a fuselage, a pair of first thrust units, a pair of second thrust units, and a pair of first wings. The first thrust units and the second thrust units are tiltably mounted on the fuselage. The first wings are securely mounted on the fuselage, and each first wing has a root end and an outer end. The longitudinal length of the outer end is larger than that of the root end. Thus, when the VTOL aircraft is landing or taking off, the airflow can pass around the root ends of the first wings; when the VTOL aircraft is cruising or gliding, the wings can provide lift, so that the first thrust units and the second thrust units can operate in a low mode, which makes the VTOL aircraft save energy and land safely even when the thrust units are broken.

Claims (42)

1. A vertical taking-off and landing (VTOL) aircraft comprising:

a fuselage comprising a length direction;

a pair of first thrust units tiltably mounted on an upper portion of the fuselage and mounted on two sides of the fuselage respectively;

a pair of first wings securely mounted on the upper portion of the fuselage and on the two sides of the fuselage respectively, and the first wings disposed behind and above the pair of first thrust units; each one of the first wings comprising:

a root end mounted on the fuselage; and

an outer end opposite the root end of the first wing; a longitudinal length of the outer end of the first wing parallel with the length direction being larger than that of the root end of the first wing;

a pair of second thrust units tiltably mounted on a lower portion of the fuselage and mounted on the two sides of the fuselage respectively; the second thrust units being disposed behind the first thrust units; and

a pair of second wings securely mounted on the lower portion of the fuselage and mounted on the two sides of the fuselage respectively, and the second wings disposed behind and above the pair of the second thrust units; each one of the second wings comprising:

a root end mounted on the fuselage; and

an outer end opposite the root end of the second wing; a longitudinal length of the outer end of the second wing parallel with the length direction being larger than that of the root end of the second wing.

2. The VTOL aircraft as claimed in claim 1 , wherein each one of the first wings comprises:

a winglet mounted at the outer end of the first wing; the winglet extending at a dihedral angle.

3. The VTOL aircraft as claimed in claim 1 , wherein each one of the first wings and second wings comprises:

a winglet mounted at the outer end the second wing; the winglet extending at a dihedral angle.

4. The VTOL aircraft as claimed in claim 2 , wherein the winglet extends at a dihedral angle and rearward.

5. The VTOL aircraft as claimed in claim 3 , wherein the winglet extends at a dihedral angle and rearward.

6. The VTOL aircraft as claimed in claim 1 , wherein each one of the first wings comprises:

a wing connecting portion at the root end of the first wing, the first wing mounted on the fuselage through the wing connecting portion; a section of the wing connecting portion being in a circular shape, an elliptical shape, or an airfoil shape.

7. The VTOL aircraft as claimed in claim 1 , wherein each one of the first wings and the second wings comprises:

a wing connecting portion at the root end of the first wing or the second wing; the first wing or the second wing mounted on the fuselage through the wing connecting portion; a section of each one of the wing connecting portions being in a circular shape, an elliptical shape, or an airfoil shape.

8. The VTOL aircraft as claimed in claim 1 , wherein each one of the first wings is a single blade, and an expansion rate of a leading edge of each one of the first wing equals to that of a trailing edge of said first wing.

9. The VTOL aircraft as claimed in claim 7 , wherein each one of the first wings and the second wings is a single blade, and an expansion rate of a leading edge of each one of the first wings and the second wings equals to that of a trailing edge of said first wing or second wing.

10. The VTOL aircraft as claimed in claim 1 , wherein each one of the first wings is a single blade, and an expansion rate of a leading edge of each one of the first wings is larger than that of a trailing edge of said first wing.

11. The VTOL aircraft as claimed in claim 7 , wherein each one of the first wings and the second wings is a single blade, and an expansion rate of a leading edge of each one of the first wings and the second wings is larger than that of a trailing edge of said first wing or second wing.

12. The VTOL aircraft as claimed in claim 1 , wherein each one of the first wings is a single blade, and an expansion rate of a leading edge of each one of the first wings is less than that of a trailing edge of said first wing.

13. The VTOL aircraft as claimed in claim 7 , wherein each one of the first wings and the second wings is a single blade, and an expansion rate of a leading edge of each one of the first wings and the second wings is less than that of a trailing edge of said first wing or second wing.

14. The VTOL aircraft as claimed in claim 1 , wherein each one of the first wings comprises multiple blades, which are:

a front blade mounted between the root end and the outer end of the first wing; the front blade being capable of moving in a direction parallel to the length direction of the fuselage; and

a rear blade mounted between the root end and the outer end of the first wing and behind the front blade; the rear blade being capable of moving in a direction parallel to the length direction of the fuselage.

15. The VTOL aircraft as claimed in claim 7 , wherein each one of the first wings and the second wings comprises two blades, which are:

a front blade mounted between the root end and the outer end of the first wing or the second wing; the front blade being capable of moving in a direction parallel to the length direction of the fuselage; and

a rear blade mounted between the root end and the outer end of the first wing or the second wing and behind the front blade; the rear blade being capable of moving in a direction parallel to the length direction of the fuselage.

16. The VTOL aircraft as claimed in claim 1 , wherein each one of the first wings comprises multiple blades, which are:

a front blade tiltably mounted between the root end and the outer end of the first wing; and

a rear blade tiltably mounted between the root end and the outer end of the first wing and behind the front blade.

17. The VTOL aircraft as claimed in claim 1 , wherein each one of the first wings and the second wings comprises two blades, which are:

a front blade tiltably mounted between the root end and the outer end of the first wing or the second wing; and

a rear blade tiltably mounted between the root end and the outer end of the first wing or the second wing and behind the front blade.
