This department, re-established in 1999 when the new NUDT was founded, contains four teaching and research sections: aerodynamics, aircraft structure, propulsion theory and engineering, and aircraft overall design. The department currently has two first-level discipline Ph.D. degree programs, six second-level discipline master’s degree programs, and two post-doctoral research stations in dynamics, aeronautical and astronautical science and technology. Among which aeronautical and astronautical propulsion theory and engineering is the National Key Discipline, aircraft design is the national key development discipline, and fluid dynamics and solid dynamics are the Hunan Province Key Discipline.
The department has a team of high-quality faculty, with young and middle-aged disciplinary and academic leaders as its core. The department now has 7 Ph.D. supervisors, 15 master supervisors, and 27 teachers with senior professional and technical titles, with 75% Ph.D. degree holders. The department has produced three Hunan Province excellent doctoral dissertations, and nine Hunan Province excellent master theses.
