Micro Gas Turbine Technology

High-efficiency micro gas-turbine power generating sets are used in a variety of engineering sectors, such as aeronautics and astronautics, distributed electric power generation, auxiliary power plants for military vehicles, and hybrid power units for automobiles, etc. In view of this, the study of this type of power plants is of major practical significance. The development history of the micro gas turbines is first presented, briefly describing the changes in structure experienced by such turbines over the past four decades. This is followed by the enumeration of some problems demanding close attention during the design of the micro gas turbine key components. In conclusion, the authors reviewed the research work conducted by some Chinese institutions engaged in this realm of study.
