[EN] Micro turbines become increasingly popular for small-scale power generation up to 100kW. However, significant challenges still remain to be faced in terms of efficiency, operating costs and environmental issues to make micro turbines competitive in relation to existing concepts. The challenge with the development of micro turbines is to minimize the losses that become increasingly large when scaling down a gas turbine in size. By following an unconventional approach, MTT (www.mtt-eu.com) has developed a concept that is not suffering from the scale-effects on efficiency. The key feature is a monolithic rotor. Basically, the turbine comprises of a single rotor including a centrifugal compressor, a rotating combustion chamber and reaction turbine. With the rotating combustor, the compressor does not have a diffuser and the turbine does not have stator vanes. In the baseline configuration a single stage compressor and turbine are used [1]. Fig.
