The term 'Plane Engine Housing' refers to the POD, which is a three-letter acronym for Powerplant Outlet Duct. This is a component of an aircraft engine that is designed to direct the exhaust gases away from the engine and out of the aircraft. It is typically made of metal and is attached to the engine's exhaust system. The POD helps to reduce noise and vibration, as well as improve the efficiency of the engine.
