The large multi-purpose civil helicopter "auspicious bird" AC313A developed by China Aviation Industry Corporation Limited successfully made its maiden flight in Jingdezhen, Jiangxi Province, marking new progress in the construction of China's aviation emergency rescue equipment system, and then add a new tool.
Helicopters are generally divided by takeoff weight to the use and level. For example, 1-ton, 2-ton, 4-ton, 7-ton, 10-ton, 15-ton, 20-ton or more. 2-ton is AC311A, 4-ton is used a lot of straight 9 / Wuzhi 19, 7-ton is the Wuzhi 10 / AC352, 10-ton is straight 20, 15-ton is AC313A, technically speaking, should be 13-ton. By all rights, the AC313A with a new French Safran engine should be able to reach 15 tons.
After the first flight, the development of the AC313A helicopter was transferred from the trial production stage to the test flight stage, and according to the plan, it will be completed in the "14th Five-Year Plan" period of airworthiness certification, and delivered to the user.
AC313A is a 13-ton large multi-purpose civil helicopter developed on the basis of AC313. AC313A is equipped with a new type of engine, which enhances the power and reliability of the drive train, upgrades the electromechanical, avionics, flight control, and maneuvering systems, and installs additional on-board equipment such as a health monitoring system (HUMS) and rotor anti-icing, as well as the maximum external The maximum external takeoff weight is 13.8 tons, watering capacity is 5 tons, and 28 crew members can be transported.
AC313A helicopter is equipped with visual and instrument flight capability, which can meet the requirements of high plateau, high temperature, high cold and other complex regions and climatic environments. AC313A helicopter aims at the weak links in China's current aviation emergency rescue equipment, through the fitting of search lights, fire buckets, electric winches, aerial broadcasting and other mission equipment, with the outstanding ability to perform fire fighting, search and rescue missions; through the improvement of the design of this type of aircraft with excellent performance in the plateau, can effectively make up for the emergency rescue and transportation of materials in Tibet and other highland areas of China. The aircraft has excellent plateau performance through improved design, which can effectively make up for the gap in emergency rescue and material transportation needs in China's Tibet and other highland areas.
Through customized design, the aircraft has the ability to carry out emergency medical rescue, emergency command, comprehensive law enforcement and other tasks, and after the addition of emergency floating system, it can also carry out sea rescue tasks, which can meet China's all-terrain all-weather multi-purpose needs, and will effectively improve the domestic large-scale civil helicopter aviation emergency rescue capabilities and high-quality supply capacity, and better support China's aviation emergency rescue capabilities. The company's newest product is a new generation of helicopters that can be used in a wide variety of applications.
AC313A is widely recognized as the civil model of the domestic military straight-8L helicopters, the two are extremely similar in appearance, the biggest difference is that the AC313A upgraded the power system, equipped with the French Aneto-1C type fifth-generation turboshaft engine, an increase of about 10% in power at the same time, but also triggered the outside world on the domestic turboshaft engines. Thinking.
It should be said that in recent years, the performance of domestic military engines has been excellent, whether it is the turbofan-10 aero engine carried by J-20, J-16, and J-10C in batch, or the QC-280 naval gas turbine used by 055 and 052D, or even the 150HB series of diesel engines used by the 99A main battle tanks and the 05-type amphibious tanks, which represent the advanced level of domestic engines in the three fields of air, land, and sea. The advanced level in the three fields of sea, land and air. Helicopters with turboshaft engines from theory, and turbofan engines can be common core machine, although this situation actually rarely happens, but in the advanced turbofan engine R & D, manufacturing system based on the derivation of advanced turboshaft engines, is really not too difficult thing.
