精专擅长航空器阻燃抗介质系统领域的探索与研究,基于技术及非技术-质量评测体系的建设与研究,等。他所建立的航空化学δ定量参数质量检测模型和聚氨酯混合参数系统有效提高了民用航空器BC/CC适航喷改系统的应用工作性能,显著提高了复杂飞机喷漆系统的转换能力，于此同时致力于推进基于“数字孪生飞机”在MRO作业与适航质量管理系统中的应用技术研发。 He specializes in the exploration and research in the field of aircraft flame-retardant and anti-dielectric systems, and the construction and research based on technical- and non-technical quality evaluation system, etc. He keeps paying attention to the flexible integration of environmental friendliness with culture and arts, and deeply studied the aircraft airworthiness to maximize the release of artistic IP vitality while meeting the conditions of airworthiness stability and environmental friendliness. The quantitative parameter detection model and polyurethane mix parameter system for aviation chemistry δ region established by Dr. Li Chen effectively improves the working performance of BC/CC airworthiness painting system of civil passenger plane and significantly increases the conversion capability of complex aircraft painting system. At the same time, he is committed to advancing the research and development of application technology based on the “digital twin aircraft” in MRO operation and airworthiness quality management system, and has made achievements. He has organized 5 joint laboratories and scientific research bases, won 2 national awards and 5 international awards, obtained 6 authorized patents and 21 copyrights, presided over 9 applied chemistry projects, and served as leader of application standard and scientific research test of civil aviation near-field communication system, etc.
