According to Wedoany.com, sourced from the Aviation Industry Corporation of China (AVIC), the "Auspicious Bird" AC313A iron bird test rig has recently completed its final assembly and delivery.

The AC313A helicopter is a 13-ton-class large multi-purpose civil helicopter developed by AVIC, designed to meet operational requirements in complex regions and climatic conditions such as plateaus, high temperatures, and extreme cold. The iron bird test rig is an "aircraft" with a steel skeleton that can never take to the skies; its purpose is to accurately replicate real flight conditions on the ground, conduct multi-system collaborative tests, and expose issues before takeoff, enabling developers to make adjustments and improvements.

It is reported that the AC313A iron bird test rig delivered this time adopts a 1:1 steel-structure simulation of the airframe framework, integrating avionics systems, control devices, and hydraulic power units, and bears the critical responsibility of helicopter system integration verification. In the next phase, the rig will undergo approximately 50 hours of ground testing, including a series of ground joint tests such as power system adjustment, torsional vibration stability, pitch-axis force relationships, and durability, providing key data support for the model's development.

To strictly meet the schedule, personnel from AVIC's helicopter plants and research institutes have worked around the clock with deep dedication and collaborative effort, upholding quality standards and safety red lines while pursuing efficiency, ensuring the smooth completion of the AC313A iron bird test rig's final assembly and fully safeguarding the high-quality advancement of the model development mission.
