Mi -26 is a dual-engine multi-purpose heavy transport helicopter developed by the Miri Design Bureau of the former Soviet Union (now renamed Miri Moscow Helicopter Factory Co., Ltd.), which was nicknamed "Halo" by the North Atlantic Treaty Organization. This helicopter is a heavy transport helicopter developed after Mi -6 and Mi-10, and it is also the heaviest helicopter in the world today.

The fuel consumption of the two engines of Mi -26 is very high, reaching 2.5 tons per hour, about 3,000 liters. The fuel consumption is high and the power is very huge, which is equivalent to the sum of the horsepower of 50 Ferrari sports cars. With huge fuel consumption, the flight cost of Mi -26 is naturally extremely high. In the Wenchuan earthquake in China, two Mi -26 helicopters participated in the post-earthquake rescue, and their core task was to transport large-scale mechanical equipment to the rescue operation area. According to Mi -26, a pilot from China who carried out the equipment hoisting task, the flight distance from Gulei Town in Beichuan to the operation area of the dammed lake is 5 kilometers, and it takes about 25 minutes for a round trip. According to the calculation of 7000 yuan per ton of fuel at that time, it was a round trip to lift an excavator, and all the expenses totaled about 30 thousand yuan. According to China Yunnan TV Network, Mi -26 was called by the State Forestry Administration of China to carry out a fire fighting mission in Cangshan, Dali, Yunnan at the beginning of 20 10, and 2.3 tons of oil was only enough to maintain its 1 hour air flight. In the fire fighting operation at that time, the total flight cost per hour reached130 thousand yuan, so it was called "oil tiger"

At the end of 2008, Longfei Professional Airlines, a subsidiary of China Harbin Aircraft Industry (Group) Co., Ltd., officially purchased the Mi -26 helicopter previously leased from Russia, and made outstanding performance in the Wenchuan earthquake rescue work. At this point, China will have two kinds of helicopters with the largest load capacity in the world. In 2007, Longfei Company, a subsidiary of Hafei Group, introduced Mi -26 by lease for the first time in China. After Mi -26 entered the "service" of Longfei Company, it has repeatedly made remarkable achievements in forest fire prevention and disaster relief, especially in the earthquake relief flight of Tangjiashan dammed lake after Wenchuan earthquake. Captain Qi was also awarded the title of "National Model of Earthquake Relief". Due to the excellent performance of the aircraft, Longfei Company decided to change the Mi -26 being used from lease to purchase. A few days ago, China handed over the property rights with Russia, and another domestic helicopter company also signed an agreement with Russia to buy a Mi -26 helicopter. On the morning of May 26th, 2008 1 1: 05, a heavy excavator weighing about 13.2 tons was hoisted to Tangjiashan dammed lake by a red Mi -26 helicopter. On May 25th, 2008, at around 15: 50, a Mi -26 heavy transport helicopter supported by Russia for emergency rescue and disaster relief in Sichuan, China, flew to Guanghan Airport in Deyang, Sichuan, and will perform the lifting task of large-scale mechanical equipment. It took only two times to transfer 230 people affected by Tangjiashan dammed lake to safety. On May 29th, 2008, the Tangjiashan dammed lake, the most dangerous dammed lake formed after the Wenchuan earthquake in Sichuan, was rescued in stages. Before the main flood season of Minjiang River comes, it will make great contributions to ensuring the peace of the land of abundance. It also highlights the lack of large helicopters in China. At 6: 06 pm on June 10, 2009, Mi -26 landed firmly on the "X" box at the temporary airport of Jiang Shui Town, Nanchuan District, accompanied by huge roar and flying dust everywhere. This indicates that heavy machinery such as excavators will be able to quickly enter the Wulong rescue site, thus greatly speeding up the rescue progress. On June 1 1, 2009, the rescue work in Wulong, Chongqing has entered the seventh day. At 9: 56 am, Mi -26 helicopter successfully hoisted the excavator to the rescue site of Wulong Mountain collapse. Previously, the Mi -26 helicopter dispatched a blower to the collapse site, and also conducted a test flight for dispatching larger excavators and other equipment. Therefore, it was awarded the title of "National Model of Earthquake Relief". Because of its excellent performance, Longfei Company decided to change the Mi -26 being used from lease to purchase. A few days ago, China handed over the property rights with Russia, and another domestic helicopter company also signed an agreement with Russia to buy a Mi -26 helicopter. 20 1 1 In September, Li Jiayun, deputy chief designer of China Helicopter Research and Development Institute and chief designer of AC31/helicopter, said at the helicopter exhibition that the pedigree of national helicopters in China is relatively sound, but heavy helicopters (with take-off weight of 20 tons) are still blank. When the reporter asked if it was true that Russian media rumored that it was possible for China and China to jointly develop a new type of heavy helicopter based on Mi -26 heavy helicopter, Chief of Staff Li said that this was not a simple cooperation with Mi -26, and he had his own ideas and plans. At present, China has purchased two Mi -26 heavy helicopters with a maximum takeoff weight of 56 tons. Mi -26, a well-known company of Longfei, has played a unique and key role in earthquake relief, but generally speaking, Mi -26 will not be widely used. It is more suitable for China to develop a 30-ton heavy helicopter.
