The BH-90 is an unmanned aerial vehicle (UAV) developed by Aero-Starloop in China.

Maximum payload is 35 kg (77 lbs).  With 60 liters of fuel capacity, the UAV is powered by a 15kw (20 hp) turbine shaft in a heavy fuel engine (HFE) propulsion system.  The aircraft is also equipped with ground collision avoidance, using a Variable Precision Rough Set (VPRS) system.  Components are modular, allowing for various configuration and upgrades.

In addition, Aero-Starloop developed a larger version: the BH-160.
