Beihang University is a new university reorganized from the Department of Aeronautics and Astronautics of Tianjin University. In other words, Beihang University was originally a part of Tianda. Both universities have the legacy of Beiyang people, and they are both good universities. But the reputation should be a little higher. The admission score is generally low in Tianda, because some majors in Tianda rank slightly lower, but they are definitely first-class in China. By the way, both universities are higher than Dalian University of Technology.
