The aero engine is often referred to as the “heart” of an aircraft, as its performance, reliability, and efficiency directly determine the overall capability of the airplane. Being one of the most sophisticated and precise power systems, it is not only the core guarantee of flight safety but also a symbol of a nation’s technological strength, industrial foundation, and defense capability. Within the entire development cycle of an aero engine, integrated testing is a critical stage. It serves as the essential verification platform for the electronic engine controller (EEC/EMU) and provides a solid foundation for ensuring the safe and stable operation of the engine. With the increasing national investment in engine R&D, the demand for advanced and secure testing solutions has grown rapidly.

This solution is built on the SIVB Simulation and Verification Platform, enhanced with reflective memory technology and multi-core controller synchronization, enabling comprehensive and system-level testing for complex engine controllers. It supports a wide range of signal tests, including LVDT, RVDT, RTD, piezoresistive sensors, speed, flow, thermocouples, liquid level, discrete signals, and analog signals. In addition, it is compatible with multiple avionics communication standards such as ARINC429, RS422, ARINC664, and Ethernet, ensuring precise and reliable data interaction. Its standardized data management and open software architecture provide high flexibility and scalability across different testing phases.

From a functional perspective, the upper-computer platform manages resources, monitors system status, configures parameters, and records simulation data, while offering playback, visualization, and automated reporting capabilities. Hardware resource management adopts a tree-based layered structure, allowing intuitive drag-and-drop mapping between logical channels defined in ICDs and physical channels in hardware resources. The signal conditioning system ensures accurate electrical matching between the simulation platform and the EEC/EMU, while the power simulation system reproduces aircraft power supply conditions under both normal and fault modes, supporting integrated verification of the EEC/EMU’s power stability.

The system also provides customizable monitoring views, enabling users to design real-time monitoring dashboards with ICD variable binding for engine model visualization. Moreover, it supports fault injection testing across multiple communication buses, allowing controlled simulation of abnormal conditions to evaluate controller fault tolerance and safety boundaries.

In terms of application, this solution is well-suited for integrated testing of engine controllers and engine health management units, particularly in the integration verification stage of the controller’s V-model development process. By offering comprehensive process and system validation, it significantly enhances the safety and reliability of electronic control systems, accelerates development, and reduces cost and risk.

The AeroEngine Controller Integrated Test Solution is more than just a testing platform—it is a strategic enabler that supports the advancement of domestic aero engine technologies toward greater autonomy, safety, and reliability.
