Helicopter carbon fiber composite fuselage application

According to reports, Russia recently decided to invest 1 billion US dollars to develop a new generation of armed helicopters, will highlight high-speed, invisible and other technical characteristics. According to the plan, with all things going well, Russia will launch a new generation of armed helicopters five years later. Among them, the body structure will use advanced all-composite materials.

In recent years, the rapid development of helicopter technology, especially rotor technology, has largely depended on the application of composite materials and nanotechnology. The application of composite materials in helicopters is called the second helicopter **.

Helicopters have complex structures and many more mobile components. Once a component is fatigued, it can easily lead to various accidents. The composite material is light in weight, high in anti-fatigue strength, and will not break suddenly. The ability to withstand impact is also stronger than that of metal. Lightning also wears impenetrable blades, which greatly improves the safety of helicopters.

In the 1990s, a "Tiger" helicopter made by Germany and France used a new composite wing blade. The American Comanche helicopter uses a fully composite, bearingless rotor system, and the composite material used in the fuselage accounts for 90% of the structure. At present, test machines for all-composite bodies have come out. It is foreseeable that advanced composite materials, especially carbon fiber, will be widely used in new-generation helicopters.
