German defense network of experts 14 Journal of the text of a detailed report on China’s status of UAV research and development, saying that despite China’s UAV technology unmanned aerial vehicles with the United States and other Western countries are still a huge gap, but in recent years by leaps and bounds, has self-development and production of a variety of types of unmanned aircraft systems.
China UAV hot pursuit of world standards
The article said that China and Russia as the military advanced the increasing demand for unmanned reconnaissance aircraft, and invest in research and development, the two countries and Western countries in the field of unmanned aerial vehicles has continued to shrink the gap. China and Russia is still the focus of analysis (usually copy), such as the United States, “Global Hawk”, “Predator” and Israel’s “Harpy” and “Heron” unmanned aerial vehicles and other equipment to existing and non-listed human-machine system, fully self-developed UAV concept is still rare, some of which theories are too great and can not be achieved because of mass production, not to mention was officially installed.
In China’s case, and its the 60th anniversary of National Day military parade, he proudly displayed to the world of its efforts to increase the use of unmanned aerial vehicles, and to independent R & D and production of such aircraft, the ability to – in his National Day military parade, a total of 10 in the short-range unmanned reconnaissance aircraft by the reading. Unmanned Aerial Vehicle fleet manager Wang Baorong (phonetic) told Xinhua interview that it belonged to 10 unmanned aircraft in three different models, to equip the PLA special forces perform a variety of reconnaissance missions.
People’s Liberation Army National Defense University, said Professor Tan Kaijia weapons experts, the latest display of these UAVs shows China’s information control systems, precision measurement and control systems and computer information processing and other fields has made considerable progress.
In fact, “Dark Sword”, “Xianglong” unmanned aerial vehicles UAVs such as the far-reaching design concept of Professor Tan Kaijia confirmed this assessment, because of China’s focus and R & D objectives are being rapidly from a small propeller Tactical Unmanned Aerial Vehicle to the high-altitude long-endurance unmanned aerial vehicles and unmanned aircraft transfer.
Has been developed by a variety of models
In addition to in 1994 from Israel Aircraft Industries to buy, “Harpy” UAVs outside, in the past 30-40 years time, China has independently developed a wide range UAV control systems, most of which are in Western countries (mainly the United States ) unmanned aerial vehicles and unmanned combat aircraft based on the concept.
Moreover, China will be in areas such as the MiG -17 and J-5 based on the research and development of the Ba-5, in the developed based on the MiG -21 F -7 converted manned aircraft such as drones. In addition, China has also developed a number of small drones, such as the Ba-2, Ba-9, they have developed in China and the subsequent pre-programmed remote control aircraft, autonomous flight system provides a wealth of experience.
China also has a number of man-portable launchers-style mini-UAV (such as the ASN-15), they are usually by the propeller-driven, short-range tactical reconnaissance missions for ground troops. The following will explain the scope of a few focused on the larger UAV reconnaissance and combat missions, although the whole model, but concentrates on China’s past, present and future unmanned aerial vehicles and unmanned aircraft concepts and common source of technology.
Future research still faces many challenges
The face of the UAV has been considerable progress in the field of China, “Han, and Defense Review,” chief editor Andrei Chang also pointed out that China’s development of unmanned aircraft faced a number of challenges: China has been on display at the Zhuhai air show does not small UAV model, but why did not mass production of its physical machines? Andrei Chang said this indicates that China in mastering the complex technical aspects of UAV still difficult. Andrei Chang is also suggested that many Chinese companies and institutions and there is no real prototype, they are just a simple idea of looking for a UAV is willing to foot the bill for foreign investors.
In early 2007, China Aviation Industry Corporation (AVIC) Tu Jida renowned aircraft designer, said in an interview that China’s unmanned combat aircraft is still in its infancy, but may be successful in the next decade. He further stressed that China will rely on its own efforts and the will to develop such systems.
Tu Quetta to the world of the interview has left such an impression – China is still developing its unmanned aerial vehicles more reliable and durable control and communication chain in order to prevent the enemy to interfere in China’s control of its unmanned aerial vehicles and reconnaissance information transmission.
However, despite China’s current military satellite network with the support of the PLA may be remote or overseas, the use of high-altitude long-endurance unmanned aerial vehicles, but also fully understand that in the era of satellite communication in the importance of UAVs.
In response, the PLA Air Force Command College Professor Chen Hong said that if there is no military satellites, U.S. military commanders can not control its thousands of miles away at the other side of the planet, “Predator” unmanned aerial vehicles. China’s move to comprehensively promote the national defense technology that the country has been doing a good job in the aviation sector to expand their preparations.
China’s main technical characteristics of unmanned reconnaissance aircraft
“No reconnaissance -5″ unmanned aerial vehicles (also called “Changhong -1″ unmanned aerial vehicles)
“No reconnaissance -5″ to the U.S. AQM-34N “Fire Bee” unmanned reconnaissance basis. This model will provide China with further promote the development of UAV technology necessary technical background. The last century, 60 years, the Chinese jet shot down a large number of unmanned reconnaissance aircraft, Beijing University of Aeronautics and Astronautics in the reverse which UAV Based on the study, began to develop unmanned reconnaissance aircraft.
By the body, optical image sensor suite, consisting of turbojet engine as well as ground stations and other concepts under the guidance of China in 1972, completed a prototype unmanned air vehicle, and later in 1976, completed a two UAV prototype. 1978, when a Chinese-designed UAV certification, and in 1981 the PLA Air Force equipment. This is a UAV is the “no reconnaissance -5″ UAV.
“No reconnaissance -5″ is the air-launched UAV unmanned aerial vehicle, in the 4000-5000 m altitude have been launched between the following opportunities for this type of unmanned combat climb to 17,500 meters altitude, when its flight speed can be up to 800 kilometers. Initially, the UAV by the modified plan -4 “Bull” bomber fired, and later changed to Y-8E turbo bracket transport.
Due to lack of real-time data links, “No reconnaissance -5″ UAV endurance time is only 3 hours, but only a reconnaissance mission during the day, if you do not upgrade to modernize, then the UAV will be unable to continue to exist. Moreover, the lack of real-time data links and control, “no reconnaissance -5″ unmanned aerial vehicles have to stay in its intended orbit, unable to adapt to the changing tactical environment.
80s of the last century, when China’s successful use of unmanned aircraft carried out a series of reconnaissance missions. After that, the Beijing University of Aeronautics and Astronautics on the “no reconnaissance -5″ unmanned aerial vehicles has been improved and re-christened as “non-reconnaissance-5A” UAV. “No reconnaissance-5A” unmanned aerial vehicles equipped with Global Positioning System and inertial navigation system, accuracy has been greatly improved.
“Grand Waterfront” Unmanned Aerial Vehicle (Chengdu Aircraft Corporation)
As one of the latest design, the Chengdu Aircraft Company “Xianglong” UAV in 2006, the Zhuhai Air Show debut. Its size, jet engine inlet and wing shape is set with the U.S. RQ-4 “Global Hawk” similar, indicating this UAV can also be used to perform high-altitude long-endurance reconnaissance missions.
In fact, it has been reported that the flight height of up to 18,000 meters, only slightly below the “Global Hawk.” According to anonymous sources, the aircraft was completed by the end of 2008 high-speed taxi tests and first flight is scheduled for early 2009.
“Grand Waterfront” unmanned aerial vehicles and engine air intakes are located in the “V”-shaped tail between the top of the rear fuselage than the “Global Hawk” in much smaller. However, according to Chinese media reports, this UAV than the “Global Hawk” unmanned aerial vehicle flying faster, up to 750 kilometers per hour around a range of up to 7,000 km.
It is reported that the aircraft take-off weight of 7500 kilograms, 650 kilograms of the task load, take-off weight is slightly lighter in the “Global Hawk”, and a lighter load (on RQ-4B “Global Hawk” unmanned aerial vehicles, for example, maximum take-off weight of to 14.64 thousand kilograms, load is 1360 kg). As the “Grand Waterfront” relatively limited range of UAVs, so it was believed only in Asia and the Pacific war.
WZ-2000 “telescope” unmanned aerial vehicles (Guizhou Aviation and Aerospace Group, also known as “WZ-9″)
And “Xianglong” similar, WZ-2000 UAV also seems to be the United States, “Global Hawk” unmanned aerial vehicle-based design, with “V”-shaped tail, the rear of the fuselage at the top with turbo-fan engines. However, WZ-2000 are smaller (length 7.5 m, a wingspan of 9.8 meters), and has an excellent stealth performance.
As an old-style unmanned aerial vehicles, WZ-2000 UAV as early as December 2003, when the completion of the first flight, and in August 2004 completed the airborne remote sensing system testing.
Although the WZ-2000 UAV size smaller, but allegedly ceiling 18,000 meters, maximum speed of 800 km, but the life time is only 3 hours. According to reports, which UAVs equipped with thermal imaging cameras and synthetic aperture radar, the task load. The detection of data through the nose for satellite communications antenna external transmission.
ASN-206 / ASN-207 UAV (Xian Ai-sheng Technology Group)
ASN-206 UAV is an early stage one of the senior tactical UAVs, but also successfully entered the PLA’s military service, one of the few UAVs. This lightweight, short-range, tactical multi-purpose unmanned aerial vehicles from Xi’an to love life and technology research and development group in 1994, and in 1996 and mass production.
It did not confirm the news that the Israeli Tadiran Spectralink Ltd. took part in UAV research and development process. According to reports, ASN-206 UAV can carry a variety of task load, and thus enforceable, such as day and night aerial reconnaissance, electronic warfare and electronic warfare (EW / ECM), field investigation, border patrols and nuclear radiation sampling missions.
ASN-206 UAV wings from the HS-700 piston engine, by the digital flight control and management operating system. ASN-206 UAV UAV research and development is an important step because it can provide real-time reconnaissance information, and old-fashioned to get unmanned aerial vehicles will need to extract the data collected.
In the National Day military parade square UAV team, ASN-207 UAV in a team leader position. It is the ASN-206 UAV improved models. It is reported that the performance of ASN-207 UAV is far beyond the ASN-206 UAV, the former life time and the task load is twice the latter, and the maximum range of up to 600 km. Are particularly vulnerable to distinguish between these two models, it is because the front of ASN-207 UAV is equipped with mushroom-type receiving antenna, to receive flight instruction from the ground station.
Attack UAV / UCAV (UCAVA)
“Harpy” unmanned aerial vehicle (Israel Aircraft Industries)
“Harpy” unmanned aerial vehicles from Israel Aircraft Industries (IAI) Construction of the Chinese UAV Another important source of research and development skills. China in 1994, purchased from Israel which an unspecified number of unmanned fighter aircraft, this has seriously affected the US-Israel diplomatic relations between the two countries triggered a crisis of confidence. By 2004, the United States compounded by China’s military exercises in the use of “Harpy” unmanned aerial vehicles, urged Israel to stop all arms sales to China.
“Habib” is not a typical unmanned aerial vehicles, but is called a “TOURS missile” weapons systems. The unmanned aircraft powered by a propeller and can be from the ground vehicle or surface warships fired. In addition, it can hover fly patrol in the mission area for some time, locate and identify high-value target.
In attacking their targets, “Habib” unmanned aerial vehicles to target the first dive, and then detonated 32 kg of high-explosive warhead would be destroyed, Prior to this, UAV sensors can collect valuable information. No R & D for the implementation of this detection, tracking and destruction of radar transmitters and other tasks (such as enemy radar and surface to air missile batteries), and from day and night and the weather.
CH-3 hollow long-endurance unmanned aircraft (China Aerospace Science and Technology Corporation)
CH-3 hollow long-endurance unmanned aircraft prototype in 2008 Zhuhai Air Show exhibit, but because of design complexity has not yet put into production. The aircraft powered by a propeller, fuselage design for the duck, that is, before the tail is located in the main wing. In addition, near the main base of the lower part of the fuselage wing carry large sensors. From the prototype of view, the aircraft is designed to carry two air to surface missiles (such as the AR-1-to-ground missiles).
“Dark Sword” unmanned combat aircraft (Shenyang Aircraft Design Institute)
“Dark Sword” unmanned combat aircraft (UCAV) in 2006, the Zhuhai air show debut. The aircraft fuselage flat, using duck-style front wing design approach, with a wingspan larger, and has supersonic, highly mobile and other features. “Dark Sword” under the fuselage of large air intakes hint at the machine at high speed, flexibility, and the angle of attack and so some of the features, and further demonstrate the aircraft shall be powered by turbine engines.
