Helicopter rotor blades are commonly used in the production of metal materials, but the blade in the Middle East dust environment due to the impact of easy to wear and tear. To solve this problem, Russia is using glass fiber and non-metallic composite materials to transform the rotor blades.
Famous Russian military enterprises of Russia Technology Group recently in its official website published the article said that Russia in Syria, Iraq and the cargo experience shows, the helicopter landing there will set off full of sand of the cyclone and even a helicopter to fly from hundreds of meters in height, can not put off the dust shrouded. This environment will accelerate the wear of the rotor blades, and affect the lift and flight maneuverability.
In view of this, the Russian helicopter company's R & D personnel using two kinds of new materials to improve the performance of the rotor. First, after doing a good job of rotor in the leading edge of the wing beam body, and technical personnel will will wing beam transverse stretch into a circular machine, 4 stigma on the inner wall of the machine will be the wing beam from beginning to end winding up with four strands of glass fiber yarn, and so repeatedly winding 144 times; then, use of titanium metal sheet for the wing beam front edge wrapping to protect there of electro thermal de icing system.
R & D staff said that the wing beam in the glass fiber and titanium reinforced protection, the strength of the Middle East to cope with sand and dust in the middle area of wear and tear, and can withstand a short strike of ground fire.
The rear section of the blade which is connected with the rear part of the wing is more and more small. In order to minimize the weight of this component, the Russian helicopter company experts with a composite material coated with rubber completely replace the traditional metal materials of the component. The company's explanation of the video shows that when the rotor flat, its blade after the internal structure of the segment is like a myriad of upper and lower openings of the hexagonal honeycomb. The honeycomb structure is more helpful to reduce the weight of the rear section of the blade, and the helicopter can fly higher.
The Russian helicopter company also master a kind of new technology, available carbon fiber composite materials in a mould to to do it the whole rotor molding, without wing spar and blade made in each section then they link up. Experts believe that this helps to improve the overall stability of the rotor and the use of life.
Because these technical details are confidential, the R & D units did not disclose the new material to the helicopter rotor weight, wear resistance, and how much improved flight maneuverability. But Russian air armies commander-in-chief bondarev recently revealed that after modified Naomi - 28NM "sky Hunter" armed helicopters will be the first installation of composite rotor, the helicopter will be 2018 years ago into mass production.
The Russian helicopter company experts said that if the helicopter meters 28NM in actual combat to verify the new material with excellent performance and more Russian armed forces and transport helicopters will be equipped with this new type of rotor.
