Research on Civil Aircraft Scenario Modeling Method Based on SysML
摘要
Due to the diversity and variability of external factors in aircraft operation, in order to avoid the deviation and lack of key requirements in the design phase due to incomplete identification of operation scenarios or insufficient requirement analysis capability, it is necessary to analyze the expected behavior of users and systems under the scenarios for the whole life cycle of aircraft design, and capture the operation interactions and interfaces in the process of behavior, in order to obtain reliable aircraft design requirements. Guided by the idea of model-based system engineering (MBSE), this paper proposes a civil aircraft scenario modeling process based on System Modeling language (SysML), which realizes scenario description through muti-perspective views and their combination, and introduces a structural framework to standardize the model-based multi-perspective scenario analysis and design requirement capture process with a logically consistent multi-view model as a bridge. Taking the take-off scenario as an example, a multi-dimensional, multi-level and multi-view scenario structured model is constructed to realize the “forward design” of aircraft requirement development, which verifies the operability and effectiveness of the method. This method is of great reference significance for improving the capability of requirement analysis and development of civil aircraft systems.
