Abstract
An air cooling system for an unmanned aerial vehicle including a propeller () driven by an engine () has at least one cooling air duct () to direct cooling air to cool a vehicle component e.g. a cylinder head. The duct has at least one air inlet and at least one air outlet. Operation of the propeller causes a pressure differential between the air outlet () and the air inlet () which draws air through said cooling air duct (). A cowling () can cover at least part of the engine, and can form a plenum and have the supply of cooling air through a front face aperture () or side walls () of the engine cowl ().
