The verification of aircraft structural strength is an important part of aircraft development process. In order to address many challenges such as verification system planning, technical capability matching, cost budget control, and cycle schedule control, this paper conducted research on model-driven requirement capturing and capability matching for aircraft structural strength building-block verification. A data capture method for aircraft strength building-block based verification requirement planning and capability matching was constructed, a model database was formed, and their mapping relationships were established. Based on the captured strength verification requirement data, a building-block verification plan was carried out to achieve full process traceability from stakeholder requirements, top-level requirements, and system requirements to verification requirements. And the plan can be classified and updated according to structure, development stage, scenario, etc. According to the building-block verification planning strategy of virtual-real integration, a planning algorithm with multiple constraints such as cost, risk, and cycle was constructed to achieve on-demand matching of verification capabilities and effective control of experimental resources. Integrating the above methods, data, and models, a Model-Based Systems Engineering (MBSE) based civil aircraft strength verification planning and management platform was built, providing strength verification planning tools for civil aircraft development.
