TJU UAVs are Chinese unmanned aerial vehicles (UAVs) developed by Tianjin University (TJU). As an academic research and development establishment, TJU is only limited to the development of UAVs. The production and marketing of these UAVs are performed by two companies via joint development agreement with TJU, and these two companies are Noble Moral Aviation (沈阳通飞航空科技有限公司) and Dong Xin Airlines (沈阳东信科技开发有限公司), both heardquartered in Shenyang. Some of the UAVs marketed by both companies are jointly developed by TJU and Shenyang Institute of Automation (SYIA, 沈阳自动化研究所) of Chinese Academy of Sciences. As of 2013, all of UAVs developed by TJU and its associates are unmanned helicopters.

    • 40 kg class turboshaft powered UAV

    40 kg class turboshaft-powered UAV is an unmanned helicopter developed by TJU in conventional helicopter layout, and the landing gear consists of a pair of skids. The general designer of this UAV is associate professor Mr. Li Zhe (李哲), and it has been deployed in various missions in over twenty provinces in China. In one of the missions, the 40 kg class turboshaft powered UAV was deployed in archaeological missions during which the onboard sensor detected underground ruins of ancient Chinese capital of Yuan Dynasty.
