Vertical takeoff and landing aerial vehicle and cooling system
A vertical takeoff and landing unmanned aerial vehicle and a cooling system for the unmanned aerial vehicle. Heat dissipation in an arm of an unmanned aerial vehicle is achieved by providing a forward-facing opening at the front end of each of a left linear support and a right linear support of the unmanned aerial vehicle, thereby achieving the purposes of lowering temperature in the arm and protecting equipment in the arm.
1. A vertical takeoff and landing unmanned aerial vehicle, comprising:
a left main wing and a right main wing;
a left front wing and a right front wing;
a main body which is engaged with the left main wing and the right main wing;
a left linear support for connecting the left main wing with the left front wing;
a right linear support for connecting the right main wing with the right front wing;
the left linear support having a first group of multiple lift propellers arranged thereon;
the right linear support having a second group of multiple lift propellers arranged thereon;
wherein the left linear support and the right linear support each have a hollow interior;
a forward-facing opening which is provided at the front end of each of the left linear support and the right linear support;
a ducted fan having trumpet-shaped duct and the ducted fan is disposed within the hollow interior at the forward-facing opening; and
wherein the trumpet-shaped duct has a front end opening and a rear end opening, and a diameter of the front end opening is larger than a diameter of the rear end opening.
2. The vertical takeoff and landing unmanned aerial vehicle according to claim 1 , wherein the fan is a ducted fan.
3. The vertical takeoff and landing unmanned aerial vehicle according to claim 1 , further comprising motors of the first group of multiple lift propellers and the second group of multiple lift propellers, wherein the motors are arranged in the hollow interiors.
4. The vertical takeoff and landing unmanned aerial vehicle according to claim 2 , wherein a rotating shaft of the fan is perpendicular to a rotating shaft of each lift propeller of the plurality of lift propellers.
5. The vertical takeoff and landing unmanned aerial vehicle according to claim 4 , further comprising at least one propulsion propeller arranged on the unmanned aerial vehicle.
6. A cooling system for an unmanned aerial vehicle, comprising:
a front end opening provided on a shell of a linear support;
a plurality of lift propellers arranged on the linear support;
a plurality of motors which are configured to be used for each lift propeller of the plurality of lift propellers in the linear support;
a ducted fan having a trumpet-shaped duct and wherein the ducted fan arranged in the linear support at the front end opening to supply air from an external environment to an interior of the linear support; and
wherein the trumpet-shaped duct has a front end opening and a rear end opening, and a diameter of the front end opening is larger than a diameter of the rear end opening.
7. The cooling system for the unmanned aerial vehicle according to claim 6 , wherein the linear support is in a straight configuration.
