SLA UAV

SLA UAVs are Chinese UAVs developed by Lanzhou Shenlong (meaning Divine Dragon) Aviation Technology Co., Ltd. (SLA 兰州神龙航空科技有限公司), most of which are integrating commercial off-the-shelf (COTS) airframe with flight control systems indigenously developed by SLA itself.

SLA unmanned helicopters

SLA unmanned helicopters are UAV developed by SLA by integrating COTS airframes with flight control systems indigenously developed by SLA itself. Every model of unmanned helicopter has applications in law enforcement,[1] environmental surveillance,[2] aerial survey,[3] agriculture,[4] disaster relief,[5] engineering,[6] mineral survey,[7] and power line inspection.[8] Most of the unmanned helicopters are gasoline-powered.

SLA multirotors

SLA has developed two multirotors as of 2013, and they are SLA-4600 quadcopter and SLA-4800 hexacopter, both are constructed of carbon fiber composite material and both are electrically powered.

SLA-500

SLA-500 is a 70 kg class unmanned helicopter developed by SLA, and it is powered by liquid-cooled engine. SLA-500 has conventional helicopter layout with a pair of skids as landing gear. Maiden flight was completed in August, 2012.[16]

SLA custom-built unmanned helicopter

SLA custom-built unmanned helicopter is an unmanned helicopter developed by SLA that is based on ultra-light manned helicopter. SLA custom-built helicopter is converted from the airframe of a single-seat manned ultra-light helicopter that is also used on another Chinese unmanned helicopter, Blue Sky 100 kg class UAV, and as a result, externally, the two unmanned helicopters from Beijing Blue Sky Rise Science and Technology Co., Ltd. (Blue Sky, 北京蓝天飞扬科技有限公司) and SLA are visually identical to each other. The difference is in their respesctively flight control systems which are independently developed by each company separately.[17]
