我国自主研发的大型多用途民用直升机AC313A，近日在极北漠河成功完成了首次高寒试飞任务。据航空工业官方消息，1月9日，AC313A在漠河起飞，经过一系列的试飞科目，包括空速及旋翼转速、环控系统试验、直升机悬停性能、平飞性能及爬升性能、发动机起动试验等，最终平稳落地，标志着首架次高寒试飞任务圆满完成。
此次高寒试飞属于科研调整试飞和取证试飞并行阶段，对气温要求极高。为了抢占最佳低温条件，试飞团队每天清晨6点整装出发，进行相关准备工作。AC313A可针对不同用户需求进行定制化设计，研发时针对我国航空应急救援装备的薄弱环节，具备高高原、高原和海上作业要求，满足全疆域全天候多用途需求。
这款13吨级大型民用直升机，在AC313的基础上换装新型发动机，提升了传动系统功率和寿命可靠性，升级了机电、航电、飞控、操纵等系统，增装健康监测系统（HUMS）、旋翼防除冰等机载设备。最大外吊挂起飞重量13.8吨，洒水能力5吨，可运输28名乘员。
按照计划，AC313A将在“十四五”期间完成适航取证，并交付用户。这款直升机的成功研发和试飞，标志着我国航空工业的又一重要突破，对于提升我国航空应急救援能力，具有重要意义。

News Content:
China’s independently developed large-multi-purpose civilian helicopter AC313A recently completed its first high-cold test flight mission. According to the official message of Aviation Industry, on January 9th, AC313A took off in Mohe, completed a series of test flight subjects including airspeed and rotor speed, environmental control system test, helicopter hovering performance, horizontal flight performance and climb performance, engine start test, and finally landed smoothly, marking the successful completion of the first high-cold test flight mission.
The high-cold test flight belongs to the parallel stage of research and development adjustment test flight and certification test flight, with high requirements for temperature. In order to seize the best low-temperature conditions, the test flight team sets off every morning at 6 o’clock for related preparation work. AC313A can be customized for different user needs, aiming at the weak links in China’s aviation emergency rescue equipment, with the requirements of high plateaus, plateaus, and maritime operations, meeting the multi-purpose needs of all regions and all seasons.
This 13-ton large civilian helicopter is upgraded from AC313, equipped with a new type of engine, improved transmission system power and reliability, upgraded electromechanical, avionics, flight control, manipulation systems, and added health monitoring system (HUMS), rotor anti-icing and other airborne equipment. The maximum external hanging take-off weight is 13.8 tons, the water spraying capacity is 5 tons, and it can transport 28 passengers.
According to the plan, AC313A will complete the airworthiness certification during the “14th Five-Year Plan” and deliver it to users. The successful research and development and test flight of this helicopter mark another important breakthrough in China’s aviation industry, which is of great significance for enhancing China’s aviation emergency rescue capabilities.
