The "Iron Bird Test Benches" is a specialized piece of equipment used for functional, performance, reliability, and airworthiness testing of aircraft and their components. It is capable of simulating the working conditions of aircraft in real environments to obtain critical performance parameters and data. It serves as an advantageous means for ensuring the precision and quality verification of products/equipment and acts as a catalyst for upgrading product performance levels.
This type of equipment is an indispensable key test facility for aircraft system integration, optimal design, airworthiness certification and delivery for operation, and continuous airworthiness. It is primarily categorized into three levels: component-level, system-level, and full-aircraft-level (with the system-level and full-aircraft-level test stands also being referred to as "Iron Bird Test Stands").
