First Coaxial UAV in China?
Beijing ZHZ Tech introduces its TD220 unmanned aerial vehicle at a Hi-tech Expo
Jun 3, 2015 (China Knowledge) - Beijing ZHZ Technology Co., Ltd., an aviation and avionics manufacturer located in , a , has displayed its independently developed TD220 unmanned aerial vehicle (UAV) at Beijing International Hi-Tech Expo.
This new type of UAV has been put into mass production and applied in military areas and surveillance for the power grids.
The hi-tech company has received a total of over 50 orders for TD220 purchase, according to its vice president.
The vice president also indicated that the workshop has an annual production capacity of 50 units of this type of plane. Sharp increase in orders was mainly driven by the improvement in product performances including intelligent features in automatic take-off and landing, hover and waypoint planning, with the continuous voyage time as high as 5 hours and a load of 100 kg.
Meanwhile, State Grid Corp of China, the nation's largest power supplier, has bought 21 units of the company's quad-rotor UAVs this year.
Beijing ZHZ Technology's portfolio of products covers UAV, airborne equipment and automatic laser bird control that are applied in electricity, agriculture, public security, emergency, marine regulation, geological prospecting and video shooting.
First Coaxial UAV in China?
The TD220 Unmanned Helicopter is one of ZHZ Technology’s the most successful products. Many years of research was spent to complete the TD220’s independent intellectual property rights. Currently,it is considered to be the most mature technology and has the largest payload capability in the domestic civilian market. Equipped with advanced coaxial-twin-rotor tailless design and intelligent HeliAP flight control system, the TD220 can automatically and independently takeoff, land, hover and conduct path planning for up to 5 hours.

Entrepreneur under 30 makes UAVs fly high
July 07, 2015
Among the entrepreneurs born after 1980, there is Tian Gangyin and his team. They have an ambitious plan to develop an unmanned helicopter to fly across the Pacific and the Himalayas.
It means a three-ton, eleven meters long unmanned helicopter will have an operation ceiling of 9200 meters above ground, with a maximum cruising speed of 300 kph.
Tian Gangyin and his college alumni Man Yi took 40,000 yuan (12,808 US dollars) respectively and set up Beijing ZHZ Technol Co. LTD. together. The money came from their parents, who saved for their wedding and housing, as People’s Daily reported.
During four years of university, Tian Gangyin spent most of the time on UAVs, and its flight controllers. He and Man Yi constantly optimized the design of the flight control system. By the end of 2007, they condensed the fly controller into a cigarette box size, which leads the field in China. They sold it at nearly 300,000 yuan (48,029 US dollars) and won their first "pot of gold" for their business.
In 2012, they developed the first electronic coaxial unmanned helicopter. Compared internationally with the same type of unmanned helicopter, their UAV has less than half the parts but with double the reliability. Due to their excellent performance, they received seven orders in the test phase.
In 2013, Tian Gangyin presented their independently developed portable electric coaxial unmanned helicopter at the Beijing International High-Tech Expo. It is the first UAV of this kind in the world.
The UAV, 1.5 meters long and 140 kg in net weight, has the ability to cope with maximum loads of 100 kilograms at a highest flight speed of 100 kph and a ceiling of 4000 meters. The endurance time of UAV is 5 hours. In addition, it can freely rise and fall in a small spatial extent with a double speed and load in comparison to rival products. Even today, the UAV is still leading the industry.
ZHZ Technol Co. LTD now has developed its R&D team from 3-4 people to 50-60 engineers. Every year, the company receives more than 100 orders of several types of UAVs.
