Airborne aerodynamic arrangement

An aerodynamic arrangement for providing a required air pressure coefficient at an area of location of at least one air port of an internal cooling system of a flying platform,

• said at least one air port being selected from an air inlet port and an air outlet port of the internal cooling system, and arranged at a desired area in an external surface of the internal cooling system of the flying platform, wherein said at least one air port opens through the external surface,
• the aerodynamic arrangement comprising at least one airfoil-shaped body arranged on the external surface facing an oncoming air flow over the flying platform at the desired area for providing a negative pressure coefficient at the corresponding desired area on one side of the airfoil-shaped body and a positive pressure coefficient at the corresponding desired area on the other side of the airfoil-shaped body when the airfoil-shaped body is oriented at a suitable angle of attack to the oncoming air flow,
• wherein said airfoil-shaped body is located near said at least one air port so that the negative pressure coefficient or the positive pressure coefficient created by said airfoil-shaped body near said at least one air port provides an air pressure gradient within the internal cooling system between the air inlet port and the air outlet port to allow the oncoming air flow to flow through the internal cooling system via the air inlet port and the air outlet port.
