On September 22, 2020, the Sixth China (Beijing) military intelligent technology and Equipment Expo opened in Beijing. The Expo invited thousands of technology products from 200 manufacturers and more than 30000 representatives from government units, military industry groups, scientific research institutes, etc. Among the equipment for the conference, the UAV exhibits of the 60th Institute of the general staff are the best. Let me show you these exhibits.

The total parameter 60 is located in the field of UAV and target machine in China. It is mainly engaged in the research and development of four series of products, including UAV, actual combat training, simulation training and target range. It has formed series and systematization, and is developing towards stealth and striking. The total number of 60 main brought unmanned helicopters and target aircraft to the exhibition.

In terms of unmanned helicopter, the two WZ-5 unmanned helicopters improved by general staff 60 are Z-5B/G light altitude unmanned helicopter and Z-5B/H shipborne unmanned helicopter. In fact, as early as the 2002 Zhuhai Air Show, the WZ-5 unmanned helicopter of the general staff's 60 Institute participated in the exhibition. This is a veritable old aircraft, but with the help of new technology, it has regained its youth.

Z-5B/G is a light altitude unmanned helicopter transformed from Z-5B. The aircraft is light and flexible, with streamlined design and invisible design. The radiator is moved to the top of the aircraft head, and the exhaust pipe of the engine is designed with grille to reduce the infrared radiation. The maximum take-off weight of the aircraft is 530kg, and it can carry 180kg mission load. The maximum level flight speed can reach 170km/h, and the cruise speed can be maintained at 80~120km/h. The aircraft greatly improves the flight performance in plateau area by optimizing the rotor and engine. The hovering lift limit is 5000m above sea level, the use lift limit can reach 6500m above sea level, and the measurement and control distance can reach 200km The flight time is 8 hours, and it can resist the wind speed of 12m/s in the take-off and landing phase, and 18m/s in the air flight.

Under the support of different mission loads, the aircraft can perform reconnaissance instruction, location and fire correction, damage assessment, border patrol, communication relay, transportation and delivery, etc. The whole system can be carried on the measurement, control, storage and transportation integrated vehicle with MV3 general tactical vehicle chassis, which meets the requirements of railway transportation and has strong mobility.

Z-5B/H is also a shipborne unmanned helicopter improved on Z-5B. The engine adopts heavy oil engine, the radiator is moved to the upper part of the engine head, the exhaust pipe of the engine adopts grille design, which reduces the infrared radiation, adopts stealth design, and shows the test picture of the aircraft in the microwave anechoic chamber. The maximum take-off weight of the aircraft is 480KG, it can carry 100kg mission load, the maximum level flight speed can reach 160km/h, the cruise speed can be maintained at 80~120km/h, the hover lift limit is 2500m above sea level, the use lift limit can reach 3500m above sea level, the measurement and control distance is 100km, it can also be extended according to the user's requirements, the endurance time is 7 hours, the wind speed can resist 12m/s in the take-off and landing stage, and 18m/s in the air flight The speed of the wind.

Because the aircraft is to take off and land on ships, it is specialized in anti-corrosion performance, and is also equipped with electric harpoon system. The harpoon landing aid system was developed by France, and was equipped on almost all the main ships after China introduced it. The UAV is equipped with a hydraulic rod with buckle structure at the lower part, which "Forks" the grating on the helicopter deck during landing, so as to complete the rigid connection between the helicopter and the landing target ship. The operation time is short, and the mechanism is simple, which can ensure the safe landing and fixation of the medium-sized shipborne helicopter under the level 6 sea condition. However, the UAV is too light, and can only adapt to the level 4 sea condition.

The aircraft adopts safety redundancy control technology, and has the functions of Shipborne autonomous take-off and landing, program-controlled flight, online mission planning and so on. By carrying different mission loads, it can perform air patrol, emergency investigation and evidence collection, search and positioning, ship detection and identification, sensitive island and reef monitoring, oil pollution identification, communication relay, directional amplifying, light and small emergency materials throwing and other tasks. Of course, the aircraft's body is still too small. It is estimated that it is a better direction for him to be equipped with 056 frigate or maritime surveillance law enforcement ship.

It can be seen that the unmanned helicopter of the 60th Research Institute of the general staff has entered the systematic development. By changing the power and mission load, it is easy to develop specialized models to adapt to various environments and meet the increasing needs of the military. Z-5B/G is a very practical aircraft for the plateau army. It can be used more easily and has low difficulty in getting started. It can help control the situation of the target area. Z-5B/H is also a very suitable equipment for the continuous surveillance, forensics, tracking and detection of the light frigate level of our army. However, this level is still a little low. The WZ6B unmanned helicopter has been developed by the 60th Institute of the general staff in 2014, Known as the Chinese version of "Fire Scout", the unmanned helicopter recently carried on 075 is also likely to be a masterpiece of the Institute. This is the freedom kingdom of research and development. I hope to see the service of these aircraft in our army's equipment sequence one day!
