describe how ships and airplanes are protected against lightning
Answers
Explanation:
In case of airplanes : The outer shell of a typical airplane is made of aluminum. Aluminum offers several benefits when used in aerospace engineering: it’s strong, lightweight, readily available, and predictable. Moreover, it’s an excellent conductor of electricity, making it ideal for use in lightning-prone aircraft. When a bolt of lightning strikes the exterior of an airplane, the electricity travels into the aluminum shell and out through another point on the aluminum.
In case of ships: Lightning over water wants to travel from the cloud to the water (or the water to the cloud). Vessels being higher than the water line make them easy targets for direct strikes and even more so if it has a metal mast and hull. We can't prevent lightning strikes so one approach is to create a safe discharge path from the highest point of the vessel to the water and hope for the best. This usually entails a lightning rod or rods connected to heavy wire like 4 Gauge or larger that is run in the shortest, most direct path away from other wires/equipment to a ground plate mounted outside the hull below the waterline. Some employ a Faraday cage to create safe zones.
