NRIST S-100 series UAV
NRIST S-100 series UAVs are Chinese UAVs developed by Nanjing Research Institute of Simulation Technology (南京模拟技术研究所) (NRIST), also known as the 60th Research Institute of People's Liberation Army General Staff Department (总参六十所), an ISO 9001 certified research/production facility headquartered in Nanjing. S-100 series UAVs are part of larger NRIST S-series UAVs. S-100. S-100 is a jet powered drone developed by NRIST with V-tail. The fuselage of S-100 is constructed of glass-reinforced plastic (GRP), with aluminum strips for strengthening, and the wings of S-100 is constructed of honeycomb GRP. S-100 is equipped  with GPS navigation and data link for real-time information transmission. Propulsion is provided by a pulsejet, and it is the first pulsejet equipped UAV in China, making China one of the few nations in the world that master the technology of pulsejet application on UAV. Specification: S-100L. Although having the S-100 designation as part of its own designation, S-100L looks like a different drone than S-100, because it is powered by a two-blade propeller driven tractor engine mounted in the nose, as opposed to pulsejet engine used on S-100. NRIST did apply the same general aerodynamic shape of  S-100 to S-100L, as both drones have cylindrical fuselage and V-tail. S-100L drone is intended for training of operators of antiaircraft weaponry. Specification: S-100W. S-100W is jet powered drone developed from S-100, and both share the same aerodynamic layout. The biggest difference between S-100 and S-100W is in propulsion: instead of pulsejet engine of S-100, S-100W is powered by a turbojet engine, with W as abbreviation of Wo-Lun Pen-Qi Fa-Dong-Ji (涡轮喷气发动机) in Pinyin, meaning turbojet engine in Chinese. In addition to different propulsion systems, S-100W also differs from the original S-100 in size, in that  S-100W is slightly smaller than S-100. Specification: See also.
