On May 21, 2020, the project 'civil aircraft RAT retraction and release subsystem' of  Nanjing Electromechanical Hydraulic Center of AVIC undertaken by Chengdu Ruineng technology officially passed the customer acceptance.

For Ruineng, it marks the beginning of the deep cooperation with Nanjing Electromechanical Hydraulic Center (609 Institutes) of AVIC. In 2017, the research and development contract of the civil aircraft RAT retraction and release subsystem was signed. During this period, it has experienced many product design adjustments and equipment demand changes from customers. With a stable technical team and a good sense of service, Ruineng fully cooperated with the customer's product development work and completed the research and development task according to the time node required by customers. The project gives full play to the company's testing experience in civil aviation airborne products and civil aircraft purple oil system, and is well received by customers.

'Civil aircraft RAT retraction and release subsystem' not only provides retraction and release test function for customer's rat actuator products, but also provides hydraulic test bench for field oil supply and rat generator test bench.
