Abstract: A cooling system is disclosed for cooling charge air in a turbocharged diesel internal combustion engine of an aircraft. The cooling system includes a charge air cooler, a charge air bypass valve, and a bypass valve actuator. The charge air cooler is fluidly coupled between the turbocharger assembly and the intake manifold, wherein the charge air cooler is configured to cool the charge air. The charge air bypass valve is moveable between a first position and a second position. The charge air bypass valve is configured to bypass the charge air cooler when in the second position. The bypass valve actuator is configured to move the charge air bypass valve between the first position and the second position.

Abstract: Method and apparatus for installing a grounding fastener in a composite aircraft structure includes structure and/or function for (i) drilling a hole in the composite aircraft structure, the hole dimensioned to provide a clearance fit with respect to the composite structure and the grounding fastener; (ii) coating the grounding fastener with a conductive fluid; (iii) inserting the grounding fastener into the hole such that the grounding fastener is in electrical contact with conductive fibers within the composite structure; (iv) securing the grounding fastener to the composite structure; and (v) attaching a conductive device to the grounding fastener such that the conductive device is in electrical contact with the grounding fastener.
