Cooling for an electronic package mounted on an aircraft engine housed in a nacelle is achieved by connecting the package to the inlet of the engine and overboard of the nacelle so that substantially continuous air flow over the electronic package will ensue from either direction depending on the varying pressure gradients adjacent the points where connections are made and the conditions exists during the flight envelope. This negates the necessity of providing positive pumping devices for effectuating the flow of the cooling air.

Cooling means for an electronic package mounted on a gas turbine engine housed in a nacelle of an aircraft consisting of a first connection means for interconnecting the electronic package and the inlet of the engine, a second connection means interconnecting said electronic package, said first connection means and the ambient overboard of said nacelle, the opening of said first connection means relative to said engine inlet and the opening of said second connection means relative to said ambient overboard being located relative to pressure gradients acting on said nacelle and said inlet being selected so that the flow of air automatically flows from said opening of said first connection means and discharging through the opening of said second connection means and alternately from said opening of said second connection means and discharging through said opening of said first connection means dependent on the pressure gradients adjacent said opening of said first connection means and said opening of said second connection means.
