Abstract
The rapid development of electric vehicles stimulates the development of structures related to their operation. Including the use of the range extending engine for electric vehicles. The use of gas turbine engines for vehicles has always been of interest. The microturbine in the range extending engine is relevant today. However, the possibility of using a microturbine as part of a range extending engine is possible under several conditions. Microturbine should be successfully mated with a high-speed generator, and the whole structure should have a high efficiency and be economically advantageous. To create such a design, it is necessary to develop a simple microturbine with a design, equipped with a highly efficient heat exchanger, which allows to obtain high fuel and operational efficiency. Microturbine should have low temperatures on the turbine wheel to maintain high environmental parameters. The use of composite materials is necessary. The results of the development and technical characteristics of a single shaft microturbine of this class for use with a high-boring generator are presented, and its applicability as a range extending engine is justified. The main problems solved in the design of microturbines are shown: issues of thermal conditions, optimization of blade machines, flow in gas-air pipes. Power plants, based on the microturbine and high-speed generator, can be widely adopted on the basis of their simple and high operating characteristics, including the range extending engine as a range extending engine.
