The image shows an airplane engine, specifically a piston-powered radial engine, which is characterized by its multiple cylinders arranged in
a circular pattern around the central axis of the engine. This type of engine was commonly used in older aircraft before
jet engines became prevalent. The engine has a propeller attached to it, indicating that it's designed for direct mechanical propulsion rather than using exhaust gases to drive a turbine. It appears to be an exhibit or model on display, possibly for
educational purposes or as a piece of historical aviation equipment.
