Abstract

An air vent mounted on the side of a jet engine nacelle provides cooling for on-board electronics. This paper investigates the geometry of the air vent and predicts the effect the geometry has on incident electromagnetic radiation. Simulations using 3D-TLM were performed to provide power density plots at 3 GHz and 8 GHz for two bounding areas of incident radiation. The field plots were used to predict how radiation was entering the vent. The return loss of the vent has also been calculated for the two bounding areas.
