Earlier, a video made countless netizens even more excited. The test flight at the -20 plateau took 50 seconds to expose the shocking picture. In the video, my country’s self-developed new generation of general-purpose helicopters, the Z-20, flew on a snowy plateau and withstood the test of severe cold weather.
It is understood that after the Z-20 enters into service, our army's air raid capability will be greatly improved, and it will play an extremely important role in areas such as transportation and rescue and disaster relief in plateau areas. In the future plan of the Navy, the Z-20 HNA version will become a carrier-based aircraft for aircraft carriers and amphibious assault ships. It can perform tasks such as transportation, carrying missiles, and logistics support. It is responsible for alerting, reconnaissance and supply, and can also perform patrols on destroyers Anti-submarine, rescue and other tasks. On the vast land of our country, the Z-20 can fly all-weather and across the territory, representing the highest level of helicopters in our country.
It is reported that since 1986, Deng Jinghui has taken root in the helicopter business. In the 2008 Wenchuan earthquake, there were no plateau helicopters in China. It was in that context that the project and development of tactical utility helicopters started. In the ten years before the Zhi-20 project was established, Deng Jinghui and his team had already begun the research on key technologies for anti-icing of the rotor. Together with the formal development of the model after the project was established, it took 20 years.
However, if you want to develop a plateau helicopter, you must overcome a key technology, the anti-icing of the rotor, which is a worldwide problem. Below 7000 meters, when the helicopter passes through low-altitude clouds with high water content, the rotor will often freeze due to low temperature and high humidity and fail to work normally. At the beginning of the development, Deng Jinghui and his team also thought about achieving technological breakthroughs through external cooperation, but they were rejected by the foreign party. He realized that the core key technology must be in his own hands, and the anti-icing technology of the rotor must be developed!
In February 2018, Deng Jinghui and his scientific research team successfully completed the final flight test verification on a snowy plateau with an altitude of more than 5,000 meters. This is the first time that Zhi-20 has entered a real and harsh environment to verify the anti-icing technology of the rotor. From that day on, China became the fourth country in the world to overcome the anti-ice technology of helicopter rotors.
