According to official news from the aviation industry, on January 9, the domestic large-scale civil helicopter AC313A took off from Mohe Airport in the Daxinganling region of Heilongjiang Province. It completed some flight test subjects such as hover performance and rotor speed, and landed smoothly. The first flight successfully completed the high-cold test flight mission.This is the first high-cold test flight of AC313A, which belongs to the parallel stage of scientific research adjustment test flight and certification test flight.
The main contents of the test flight subjects includeAirspeed and rotor speed, environmental control system test, helicopter hovering performance, level flight performance and climbing performance, engine starting test, etc.Multiple items.
According to reports, high-cold test flights have strict temperature requirements. The test flight team is not afraid of low temperatures of more than minus 30 degrees and strong winds. They set out at 6 a.m. every morning to carry out preparations related to scientific research and test flights in order to seize the best low-temperature conditions that day.
The AC313A is a 13-ton large-scale multi-purpose civil helicopter developed on the basis of the AC313. It is equipped with a new engine to improve the power and life reliability of the transmission system. It also upgrades the electromechanical, avionics, flight control, control and other systems, and adds airborne equipment such as a health monitoring system (HUMS) and rotor anti-icing. The overall performance, life and maintainability of the helicopter are significantly improved.
The maximum external sling take-off weight is 13.8 tons, the water spraying capacity is 5 tons, and it can transport 28 crew members.
It has visual and instrument flight capabilities and can meet the requirements for use in complex areas and climatic environments such as plateaus, high temperatures, and high cold.
Tao Chong, chief manufacturing engineer of AC313A, said,In the early stages of development, AC313A targeted the weak links of my country's aviation emergency rescue equipment, and carried out a large number of improvements in terms of aircraft life, reliability, maintainability, and environmental adaptability;
At the same time, customized designs are carried out to meet the rescue needs in various disaster scenarios and the individual needs of customers. By adding fire buckets, electric winches, emergency flotation and other equipment, it can meet the emergency rescue needs of special environments such as plateaus, alpine colds, plains, and seas. It has strong mission equipment modification capabilities and emergency rescue operation capabilities, which can effectively support the construction of my country's aviation emergency rescue system.
