Claim 0:
1. A vertical takeoff and landing unmanned aerial vehicle, comprising:
a left main wing and a right main wing;
a main body which is engaged with the left main wing and the right main wing;
a left linear support connected to the left main wing;
a right linear support for connected to the right main wing;
a first group of multiple lift propellers arranged on the left linear support, a first lift propeller in the first group of multiple lift propellers has a radius of gyration;
a second group of multiple lift propellers which are arranged on the right linear support, each lift propeller in the second group of multiple lift propellers having a radius of gyration;
wherein the left linear support and the right linear support each having a hollow interior;
wherein a first motor is arranged in the hollow interior of the left linear support to drive the first lift propeller;
at least one air inlet disposed below the first lift propeller in the first group of multiple lift propellers and said at least one air inlet is provided on a top side of the left linear support; and
at least one air outlet disposed below the first lift propeller on the top side of the left linear support;
wherein the at least one air inlet is disposed directly below an outer 75% portion of a radius of gyration of the first propeller, thereby allowing a high pressure downward airflow created by a gyration of the first propeller to naturally drive a flow of air into the hollow interior via the at least one air inlet to create pressurized air in the hollow interior;
wherein the at least one air outlet is disposed directly below an inner 25% portion of the radius of gyration of the first propeller, and a space directly below said inner 25% portion of the radius has a low pressure downward air flow, thereby allowing pressurized air within the hollow interior to naturally escape from said hollow interior to an ambient environment through said at least one air outlet; thereby directing the flow of air to pass to and from the first motor.
