Ace major is aircraft manufacturing engineering of the Academy of Aerospace Engineering, formerly known as the Aviation Engineering Department established by 1978. At present, there are three undergraduate majors (two majors and one international cooperation class): aircraft manufacturing engineering, aircraft manufacturing engineering (aviation maintenance engineering and technical direction), aircraft design and engineering, and engineering mechanics. Among them, aircraft manufacturing engineering is a characteristic specialty jointly established by the Commission of Science, Technology and Industry for National Defense and Liaoning Province, a demonstration specialty for undergraduates in Liaoning Province, and a core specialty of the training base for aerospace talents in short supply in Liaoning Province. It has the right to award master's degrees in aerospace science and technology and three master's degrees in two disciplines (aerospace manufacturing engineering, aircraft design and engineering mechanics), as well as the right to award master's degrees in aerospace engineering. Among them, aerospace manufacturing engineering is a characteristic discipline established by the Commission of Science, Technology and Industry for National Defense and Liaoning Province, and it is also two key disciplines during the Eleventh Five-Year Plan period.
