#ARCTIC. #SIBERIA. THIS IS TAIMYR. Engineers of the NTI competence center Digital Materials Science on the basis of MSTU named after N.E. Bauman created an impact-resistant and anti-icing coating for turbojet engines. Its erosion resistance is at least twice as high as that of foreign analogues.
According to the leading engineer of the NTI competence center Sergey Grishin, the coating was successfully tested in Arctic conditions.
“The materials were tested on a stand simulating a flight altitude of 6 to 7.6 thousand meters at temperatures from –20 to –30 degrees under icing conditions. According to the tests results, there was practically no ice on parts of the engine coating developed by our engineers and on those surfaces where a standard coating was used, its thickness reached seven millimeters”, the expert explained.
The coating is made on the basis of polyurethane, which gives it high strength, and organosilicon compounds – for hydrophobicity. The developed composition provides both an anti-icing and impact-resistant effect.
Abrasive wear of surfaces protected by such a coating is minimized, which affects such characteristics as fuel consumption, operational stability, maintenance costs and flight safety of the aircraft.
“The uniqueness of the development lies in the fact that the coating, due to its extremely high strength, impact strength and low surface energy, simultaneously protects the surface from abrasive wear and significantly reduces ice formation”, emphasized Sergey Grishin.
According to him, the coating can be used to improve flight safety, reduce fuel consumption and the cost of servicing aircraft, unmanned aerial vehicles, ships and equipment operating in the Arctic. It will also be useful as anti-icing protection for electrical structures, roofs and building facades.
Earlier, This Is Taimyr reported that Il-114-300 aircraft were being tested for flights in the Arctic.
