Turbojets work by compressing, combusting, and releasing air through a turbine. This model expresses this method in a colorful, easy-to-understand way. Approximately 19″x9″ at its base, the turbojet is designed for use on a desktop as an educational demo. The turbine can be spun using a wheel at one end, demonstrating the way the jet works. This model works well for physics classes focusing on jet engines, air compression and dynamics, and the Brayton cycle.
