The aero-engine, often hailed as the “flower of industry,” stands as the heart of an aircraft and a critical benchmark of a nation’s technological and industrial strength. With the advancement of the “Defense Technology Industry 2025” strategy and the “13th Five-Year Plan” for defense-industry integration, China’s aero-engine development faces higher standards for verification and testing. The engine control system, particularly the Electronic Engine Controller (EEC) and the Engine Health Management Unit (EMU), plays a pivotal role in ensuring engine performance, safety, and reliability. Efficient and comprehensive testing of these systems has therefore become a critical challenge.

To meet these demands, we present the SIVB-AESBench Aero-Engine Control System Simulation & Test Solution. Built upon the HWA-SIVB simulation platform, this solution provides a robust, modular, and scalable system-level testing environment designed specifically for aero-engine control systems. It enables complete coverage of functional testing, performance verification, and fault injection, ensuring thorough validation across the development cycle.

The primary testing targets of SIVB-AESBench are the EEC and EMU, focusing on system-level integration and verification phases. The platform is capable of simulating a wide range of sensor signals—including LVDT, RVDT, fuel flow, thermocouples, RTDs, vibration, and pressure sensors—as well as actuator signals such as current- and voltage-controlled valves. In addition, it supports real-time simulation of bus signals, including RS422, AFDX, and ARINC429, ensuring high fidelity with real-world operating conditions.

Fault simulation is one of SIVB-AESBench’s defining strengths. The system can replicate physical signal anomalies such as open circuits, short circuits, impedance mismatches, and grounding errors. Beyond hardware-level failures, the platform also allows for protocol-layer fault injection for communication buses, enabling rigorous validation of redundancy and fault-tolerance strategies in the control system.

Technically, SIVB-AESBench adopts a distributed simulation architecture, combining Ethernet for command transmission and reflective memory for data synchronization. This design ensures high-speed communication and robust real-time performance under complex scenarios. The platform further supports FPGA-based real-time simulation, achieving nanosecond-level precision, which is essential for replicating high-frequency dynamic processes.

The software suite of SIVB-AESBench provides comprehensive functionality, including project configuration, signal simulation, test execution, data visualization, and post-test analysis. Its modular design allows rapid adaptation to different testing requirements without altering core software. The visualization tools support multi-screen monitoring with drag-and-drop layouts, offering an intuitive view of test progress and outcomes. The well-defined workflow guides users through system self-checks, configuration management, power-up validation, automated test execution, fault injection, and final report generation—establishing a closed-loop testing process.

Automation is another core advantage. Users can easily build and execute custom test cases through the integrated test case library and standardized interfaces. The system supports both open-loop and closed-loop debugging and enables synchronized injection of model-driven stimuli and faults, ensuring high efficiency and accuracy in complex testing tasks.

Currently, SIVB-AESBench has been successfully deployed in the development and testing of next-generation aero-engines, including the CXX-1000 and CXX-2000 programs. Its adaptability, reliability, and comprehensive features have proven indispensable in advancing China’s independent aero-engine R&D.

The SIVB-AESBench Aero-Engine Control System Simulation & Test Solution stands as a cornerstone technology in modernizing China’s aviation power systems. It provides a solid foundation for ensuring the safety, reliability, and advancement of aero-engine control systems, driving innovation and securing national technological independence.
