Abstract:

Given the characteristics of multi-machine combined operation and virtual-reality integration in multi-machine collaborative validation testing in a ground test environment, this paper presented a model-based virtual and real integration technology for multi-machine collaborative validation testing. The environmental architecture design was verified using the virtual and real integration technology. The semi-physical aircraft (airborne equipment and, a small number of auxiliary simulation models), the core aircraft (airborne computer type equipment and, supplementary simulation models), and the digital aircraft (mission systems and flight simulation models) served as the verification object. By employing the methods of “model in the loop” and “supplementing reality with the virtual,” utilizing the validation testing acceptance process, combining the virtual-real interface adaptation technology, difficulties encountered in conducting comprehensive system testing due to missing or imperfect functions of onboard equipment or systems were overcome, and issues such as the inability of the traditional interface-level simulations to meet the time sequence and function logic requirements of comprehensive system testing were addressed. This facilitated rapid simulation iteration validation throughout the entire process, enabling early identification of emergent properties in the system, providing decision criteria for system design quality, supporting rapid iteration optimization of system design, and reducing development cycle and costs.
