| Summary: | One of the main microturbine plant elements is a turbine impeller. Development of effective turbines
demands considerable costs, that is why the method of turbine design based on existing prototypes
is offered. Microturbines have a high-speed rotor. Therefore, there is a problem related to strength
ensuring of the turbine at high speeds of rotation. In this article it is said about gasdynamic and strength
optimization of turbine impellers. The offered method allows to reduce stresses in a turbine impeller
during an operating mode without changing of useful gasdynamic characteristics. Several modifications of
blade and wheel joint are considered in this research and also strength analysis is presented. Verification
of method of turbine design is carried out. It based on the strength and gasdynamic analysis of working
processes in a flow channel of the microturbine |
