Jet engines are referred to as turbines. Technically they are Turbofan or turbojet turbine engines depending on how the jet fuel is used to generate thrust. Almost all modern jets use turbo-fan turbine engines. A series of turbine blade wheels work with stationary stator blades to compress a fuel / air mixture to very high pressure, a series of igniters ignite this highly compressed mixture of compressed fuel/air and the combustion creates the energy to spin a powerful fan and generate thrust. Each engine on a jet or jet-prop airplane is indeed a turbine. I fly jets for a living.
