SunHawk Aviation S100 "Small Whirlwind" stuns at the Zhuhai Airshow

　　At 11 o'clock on November 6, 2018,SunHawk Aviation(Henan) industry co., ltd. held the world premiere ceremony of the unmanned helicopter S100 "Small Whirlwind" at booth H6B4 in Hall 6 of Zhuhai Airshow. As the first company to release new products at this year's air show, the s100 broke the design concept of conventional drones with a longitudinal arrangement twin-rotor helicopter structure, which has been highly recognized and praised by the industry insider.Zhengfeng Wan, the Vice Mayor of Zhengzhou Municipal People's Government, member of the party group, director of the Zhengzhou District Administrative Committee of the China (Henan) Free Trade Zone, and Yongjun Geng, he head of the Shangjie District of Zhengzhou City, attended the opening ceremony of the S100 "Small Whirlwind".

Liang Tao, CEO of our company, was interviewed by CCTV.

The main advantage of longitudinal arrangement twin-rotor helicopter is that its rotor is arranged in longitudinal, the space occupied by the folded rotor is small and very convenient, and the mission load is not disturbed by landing gear. The direct advantage of longitudinal arrangement twin-rotor helicopter is that its loading capacity is obviously improved compared with the traditional single-rotor helicopter. Because there is no tail rotor power consumption as a single rotor helicopter usually does, so that the load capacity is also greater. And at a lower paddle, the load can get the best performance, bigger range in longitudinal center gravity, and the hovering efficiency is higher. The longitudinal twin-rotor helicopter has the congenital advantage of smaller diameter of the paddle disc under the same load. It has the strong anti-crosswind ability and it also has a large control margin in strong wind environment.

The longitudinal arrangement twin-rotor unmanned helicopter is composed of engine, transmission system, frame, two reduction gearboxes, two sets of hubs, two sets of rotor, two sets of tilting discs, control steering gear, flight control unit, communication link, ground radio, ground workstation and so on.Mainly it can be used in agriculture and forestry plant protection, forest fire prevention, police patrols, counter-terrorism， reconnaissance，field search and rescue, power line inspection, petroleum pipeline patrol and disaster investigation etc.
