China Academy of Aerospace Aerodynamics Weapon Systems
China Academy of Aerospace Aerodynamics is a Beijing-based CASC academy focused on aerodynamic research, wind-tunnel testing, and UAV development, including the CH-series aircraft family connected to this catalog.
1 weapon systemsChina Academy of Aerospace Aerodynamics is a Beijing-based research and production academy inside China Aerospace Science and Technology Corporation (CASC). Open-source references commonly describe it as the 11th Academy and trace its lineage to China's early aerodynamic research institutions.
For this archive, the builder profile provides context for the Chinese unmanned-aircraft and flight-vehicle systems tied to CAAA's aerodynamics expertise, including the Rainbow/CH family of UAVs and newer cargo-drone work.
Notable Systems
CH-4 Rainbow UAV
Janes reports that CAAA is CASC's UAV development arm and that the Taizhou Rainbow UAV Base began delivering CH-4 aircraft.

Predecessors
Public English coverage uses multiple historical names and academy-number aliases for CAAA, so the profile normalizes them under the current builder name. No rights-clear reusable builder image was verified during this task, so images are omitted.
