Aircraft electrification is a topic of increased interest in the industry. It affects many aircraft systems that were traditionally mechanical or hydraulic. Engineers seek more effective test strategies to ensure high reliability, performance, and operational safety. In this example, the SCALEXIO system is integrated in a test rig for electromechanical actuators used as backup for high-lift surface control. It achieves a scalable closed-loop environment by providing control, fault injection, measurement, monitoring, and data acquisition capabilities. Real as well as simulated pilot commands, are used as input to cover complete flight missions for repeatable and automated testing. In addition, the SCALEXIO system provides a single platform for testing the integrated system, including software verification. This flexibility is achieved by enabling simulation of the entire system, individual components, such as power electronics, or only the environment.
