CAS UAVs are Chinese UAVs developed by Chinese Academy of Sciences (CAS). Most of CAS UAVs are developed by Beijing (Tian-Yu (meaning Sky Universe) Smart Map Co., Ltd. (TYSM, 北京天宇智图有限公司) ), a company that is wholly owned by (Institute of Atmospheric Physics, (中国科学院大气物理研究所) ) of CAS. TYSM have developed both the fixed-wing and rotary-wing UAVs, with the rotary-wing UAVs classified by the payload carried, while the fixed-wing UAVs are named as Expedition (Yuan-Zheng, or Yuanzheng 远征).〔(Expedition series UAV )〕 ==5 liter class UAV== 5 liter class UAV is a gasoline-powered unmanned helicopter developed by TYSM by utilizing commercial off-the-shelf (COTS) airframe with flight control system indigenously developed by TYSM. 5 liter class UAV is in conventional helicopter layout, and the landing gear consists of a pair of skids. 5 liter class UAV is mainly designed for agricultural applications, and it can carry up to 5 liters of liquid chemical for crop dusting.
