电磁弹射系统多元交互式安全性设计新理论与新方法

The composition of Electromagnetic Aircraft Launch System (EMALS) is sophisticated and interacts with one another intensively. Safe and reliable operation of EMALS is a prerequisite for carrier-based aircrafts to take off and execute tasks securely. Therefore, it is urgent to conduct research on fundamental theories of system safety under complicated interactive relationships for EMALS. This project focuses on solving the problems caused by insufficient consideration of complicated interactive relationships among staff uncertainty, equipment reliability, environment complexity, and mission specificity. Firstly, by considering staff, equipment, environment, and mission comprehensively, propose the multivariate interactive model for safety design and the construction method for hierarchical frame of key safety index (KSI) with respect to system safety as top-level requirements at the design stage. Secondly, propose the normalization method of multi-source heterogeneous data based on ontology modeling to construct the expandable database of fundamental safety-related data and propose the KSI construction method based on weakly-supervised deep learning technique to quantitatively calculate KSIs. Thirdly, propose the verification methods for the KSI frame under different categories and the quantitative technique of interactive coordination optimization under multiple targets to achieve optimized safety design via KSI improvement. Finally, apply the safety design methods on the energy storage device, which is a key component of EMALS, to validate the effectiveness of the proposed methods. Research findings of this project shall show great theoretic meanings and engineering application values in aspects of improving EMALS performance, ensuring success of military missions, reducing cost, and eliminating casualty.
