Revolutionizing Turbine Blades: The Heart of Modern Aircraft Engines
Turbine Blade Introduction The component with the worst working conditions in the turbine engine is also the most important rotating component. In the hot end components of aircraft engines, the turbine blades are subjected to high-temperature gas erosion and temperature changes during the engine start-up and shutdown cycles, and the rotor blades are subjected to […]
Graphical introduction to the main components of aircraft engines
Turbine Blades Hot end components, turbine blades belong to the hot end components of aircraft engines. They need to work in a high temperature and high pressure environment and are the most difficult blades to manufacture in turbofan engines. High temperature and high pressure combustion gas expands in the turbine, driving the turbine to rotate […]
How much do you know about the strength design issues and challenges of aviation gas turbine engines?
The aviation gas turbine engine (hereinafter referred to as the engine) is a rotating mechanical product that integrates high temperature, high speed, high pressure and complex vibration environment. How can a high-speed rotating machine working in such a harsh environment have high reliability, safety, economy, comfort (low noise and low vibration) and long life, while […]
Crack analysis method for integral blade ring of aeroengine
With the continuous improvement of aircraft engine performance, high thrust-to-weight ratio has become an important indicator of advanced aircraft engine performance. Therefore, the development of advanced high structural efficiency and high-performance materials with lightweight overall structure has become the main development trend. The integral blade ring structure using continuous fiber reinforced titanium-based composite materials has […]
Causes, hazards and preventive measures of steam turbine water hammer
1. Concept of Steam Turbine Water Hammer Turbine water hammer, that is, the accident caused by water or cold steam (low-temperature saturated steam) entering the steam turbine, is one of the most dangerous accidents in steam turbine operation. Such accidents occur frequently at home and abroad and will cause serious consequences, so boiler and steam […]
100 questions to help you understand gas turbines from all angles
What is a gas turbine? Answer: A gas turbine is an internal combustion power machine that uses a continuously flowing gas as a working fluid to drive the impeller to rotate at high speed, converting the energy of the fuel into useful work. It is a rotating impeller heat engine. What thermodynamic processes are included […]
Why do aircraft engines use integral blades?
01 Advantages of the integral blade Before the emergence of the integral blade disk, the rotor blades of the engine needed to be connected to the wheel disk through tenons, mortise and tenon grooves and locking devices, but this structure gradually failed to meet the needs of high-performance aircraft engines. The integral blade disk that […]
