On April 24th, the Kunlong AG600 completed a demonstration and verification of water rescue and air drop rescue at Zhanghe Airport in Jingmen, Hubei. During the test, the aircraft and surface rescue forces cooperated well, and the rescue implementation process was smooth. The AG600 has preliminarily completed the verification of water rescue mode. This demonstration and verification of water rescue is an important part of the overall implementation of the spirit of General Secretary Xi Jinping's important instructions and instructions on aviation industry and AG600 series as well as the requirements for the construction of emergency rescue system. It is another major breakthrough after the verification of fire fighting mission capability, and provides important technical support for the subsequent development of AG600 aircraft search and rescue. The AG600 water rescue demonstration verification includes both water rescue and airdrop rescue. The rescue drill focuses on verifying the key processes of aircraft low-speed sliding on the water surface during water rescue, such as lowering the boat, exiting the boat for rescue, and receiving the boat from the side, as well as the use of airdrop equipment and the process of parachute deployment during airdrop rescue. Through this exercise, the low altitude and low-speed performance as well as surface maneuverability of the AG600 aircraft have been once again verified and supplemented, especially in terms of surface twin engine and four engine slow driving, downwind and upwind sliding characteristics, and turning characteristics; Secondly, the collaboration between mission personnel and the ability to collaborate with flight crews and command centers has been fully validated, resulting in standardized commands and gestures; Each operational link and action detail during the rescue process has been supplemented and improved through repeated deduction and iterative verification, and has formed a standard example; The rationality and feasibility of the task system configuration have been verified, and the direction of iterative optimization has been clarified, gradually implemented and improved in subsequent development; The personnel configuration and workload for this task have been preliminarily verified, forming basic evaluation standards and configuration requirements! This demonstration verification will be implemented on the AG600 technology verification machine, and the related capability verification of AG600M at sea will be completed in the future.
