Turbine Basics – Turbine and Blade Cooling Technology
Axial flow turbine structure A turbine is a rotary power machine that converts the enthalpy of a working fluid into mechanical energy. It is one of the main components of aircraft engines, gas turbines, and steam turbines. The energy conversion between turbines and compressors and airflow is opposite in procedure. The compressor consumes mechanical energy […]
Analysis of the development history, market status and development trend of turbine blades
Development History and Trends of Turbine Blades Turbine blades are divided into two categories: turbine guide blades and turbine working blades. The main function of turbine guide vanes is to adjust the flow direction of the exhaust gas from the combustion chamber. The material operating temperature can reach up to over 1,100°C, and the stress […]
