The New Era of Combustion Chamber Manufacturing: How CNC and 3D Printing Reshape Efficient Production
The combustion chamber, the “heart” of aircraft engines and gas turbines, have struggled to overcome issues such as long production cycles (8-12 weeks), low yield rates for complex structures (<70%), and high mold costs (30% of total expenses) for some time. As the global gas turbine market is expected to exceed $30.8 billion by 2025 […]
A comprehensive comparison of the differences between gas turbines and steam turbines
Turbofan engine Also known as the “turbofan engine”, it is developed from a turbojet engine, with a fan and a low-pressure turbine added to the core engine. The fan rotates to compress the air, and the compressed air is divided into two streams. The outer stream flows in parallel and is directly discharged through the […]
Beyond the Blades: The Turbine’s Vital Role in Gas Turbine Efficiency
The role of the turbine The high-pressure and high-temperature combustion gas coming out of the combustion chamber expands and decelerates to impact the turbine to do work. This drives the compressor to do work, and drives the accessories to work through the accessory casing transmission. Turbine compresses gas? Who can compress high-temperature and high-pressure gas? […]
From Air to Power: Understanding the Gas Turbine Engine
Working Principle of Gas Turbine The compressor, driven by the turbine, continuously draws in air from the atmosphere and compresses and increases its pressure. The compressed air enters the combustion chamber, mixes with the injected fuel and burns. After becoming high-temperature combustion gas, it flows into the turbine to expand and do work. After doing […]
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 […]
