    Department of Aeronautical Structural Engineering was founded in 2003. It was formerly known as 504 Teaching and Research Section of the Aircraft Engineering Department (which was founded in 1959) and Aircraft Structural Strength Research Institute of the Northwestern Polytechnical University (founded in 1981). The department consists of the two national key laboratories: the State Specialized Laboratory of Dynamics and Strength, and the National Defense Key Discipline Laboratory of Aircraft Structural Mechanics and Strength Technology. It is also the fundamental part of the state key discipline of Solid Mechanics in NPU.

    The department is involved with the undergraduate education of two specialties: Aircraft Design and Engineering and Theoretical and Applied Mechanics. The major discipline for M.S. and Ph.D. degree programs is the Solid Mechanics. The department also accepts post-doctoral researchers each year. Research areas of the department focus on the structural fatigue, fracture and reliability, multi-scale mechanics, aeroelasticity, structural vibration control, impact dynamics, strength of composite materials, and computational mechanics.

    The department consists of four research institutes and has 38 faculty members, including 19 professors, 8 associated professors and senior engineers, and 9 lectures. The department has a total enrolment of over 120 postgraduate students.
