Abstract

The publication focuses on some questions about calculation and design of thermomechanical engines and thermal power plants developed by alloys with shape memory.

Also, some requirements for the alloy defined when it is used as an active element (actuator) in thermomechanical engine and in the power plant.

Next, there goes classification of active elements and recommendations for its selection for the maximum efficiency and adaptability.

There are also given some fundamentals of design of thermomechanical engines with active elements based on alloys with shape memory, then there goes engineering method for calculating the thermomechanical engine.

Finally, there goes a theoretical researching of special type power plant turbine working in two environments (water-air) and the possibility to create an installation of this type.

Keywords:
