This turbo jet engine model of a modern two-wave turbine shows in detail the construction and the operating system of such a motor. Low-pressure and high-pressure compressor, low-pressure and high-pressure turbine are readily recognisable, as also are the combustion chambers with the injection nozzles and starting plugs. These can be readily seen thanks to the section cut housing. The turbines can be set in motion with the built-in electro-motor. • On the base
