Claim 6:
7. A cooling system for an unmanned aerial vehicle, comprising:
a plurality of lift propellers arranged on a linear support of the unmanned aerial vehicle;
wherein the linear support has a hollow interior and contains a plurality of motors to drive the plurality of lift propellers;
at least one air inlet disposed below a first lift propeller of the plurality of lift propellers and said at least one air inlet is provided on a top side of the linear support;
wherein the first lift propeller is driven by a first motor of the plurality of motors; and
at least one air outlet disposed below the first lift propeller on the top side of the 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 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.
