Korean media warned that China’s unmanned aircraft have serious flaws should be cautious development
[World Wide Web reports South Korea’s military site, “the Silla Air Force Forum August 16, 2012, published an article on the U.S. Navy in 2013 declared that X-47B UAV autonomous takeoffs and landings on the carrier The messages were analyzed. The article, as the world’s best technical performance unmanned aircraft X-47B is not only leading the development of unmanned aircraft in the world, but also embodies the common problem of many existing unmanned aircraft, such as radar, mobility and function expansion the limitations of the As high-speed rise of the country, China not only should be cautious development of unmanned aerial vehicles, we must beware of the United States as a tool to the UAV China into high-end arms race.
First, the unmanned aircraft obvious defects, and inability to balance fighters.
in a number of active duty U.S. military and research equipment, the X-47B unmanned aircraft has been a star equipment. Not only is it the first UAV based replace someone fighters from the actual stage, but the UAV is also regarded as an effective means of one of the United States to counterbalance China’s anti-ship ballistic missile. In accordance with the U.S. Navy’s vision on the next-generation Ford-class nuclear aircraft carrier, the X-47B will be used as the main one of the aircraft carrier out equipment. Although the machine can not completely replace the traditional “Super Hornet” series of carrier-based aircraft, but efficient stealth performance and ultra-long range will allow U.S. aircraft carrier battle groups to combat the effect of the distance and the fight against the nature of upgrading. However, many technical details from the X-47B unmanned aerial vehicles which reflect the point of view, this UAV is subject to the limitations of its own radar, mobility and functionality to expand, not only difficult to effective alternative fighter in service, but also in The future air combat it is difficult to pose a threat to someone fighter.
Russian-made MiG -21 fighters as the third-generation fighter in good works, not only had served in many countries, but today, the technology upgrade version of the fighters have been endless. But despite the technical staff through the new wing and engines to enhance the maneuverability of the fighters, but the nose the rectifier cone small space of the fighters face great radar upgrade limitations, such limitations also exist in the X-47B above the unmanned fighters. Fifth-generation fighter R & D program with the United States similar to the X-47B UAV attaches great importance to the stealth performance from the outset, so similar to the B-2 strategic bombers flying wing aerodynamic layout. But the huge gap in size subject to the flying wing is too flat structure and the X-47B compared to B-2, X-47B UAV nose space for the loading of radar space like a MiG-21 fighter the rectifier cone narrow. The United States has been advertised to the future of UAVs a key technical performance is independent detection and attack, but the small head space caused by the lower radar performance is no doubt that this concept is difficult to achieve in the X-47B UAV.
direct successor as the B-2 strategic bomber wing aerodynamic layout, the X-47B UAV seems from the outset, giving a superior mobility The impression of the performance. However, the facts or is not the case, the X-47B unmanned aircraft used Pratt & Whitney F100-220U non-afterburning turbofan engine. Therefore, the X-47B does not actually have a supersonic cruise, and even supersonic flight capabilities of its combat forces to play a completely rely on stealth performance, the higher altitude and the U.S. for its variety of specially developed new types of ammunition. This development pattern is very similar to the US-made F-117 stealth fighter, too utilitarian thinking has made the Nighthawk fighters suffered heavy losses. Similar to the “Nighthawk” yes, at this stage, as a new fighter, the X-47B, it is difficult to imagine this UAV in addition to act as a performance of a single unmanned aircraft, can upgrade like the “Super Hornet” “Growler” as assume other combat missions. In view of the serious limitations of radar, the power unit and functional development, or will make the X-47B compared to “Raptor” fighter is more difficult labor, a more limited role in actual combat.
Second, China should be cautious development of similar high-end X-47B unmanned aircraft.
, although there is no clear evidence that China has been equipped with high-end similar to the US-made Predator or Global Hawk unmanned aerial vehicles, but China in UAV The technical achievements are obvious to all. At present, China has been on UAV technology over comprehensive than Russia, Europe and Israel the same after the second tier of the United States. Therefore, when the U.S. X-47B UAV unveiled not only the international community has a lot of point of view, should also have the necessary research and development of similar high-end unmanned aerial vehicles, UAVs early model of China’s own exposure also shows China are exploring the basic performance data of the X-47B flying wing UAV. However, these are difficult to prove that China has committed to research and development of high-end similar to the X-47B unmanned aircraft. In fact, the high-end unmanned aircraft is one of the most in need of careful development and equipment.
X-47B unmanned aircraft represents the highest technological achievements in the UAV field, but the unmanned aircraft’s overall development of the X-47B may be regarded as an early demonstrator type. As we all know, compared to manned aircraft, the greatest advantage of UAVs is a random pilot removed, thanks to this, unmanned aerial vehicles eliminating the need for a huge life-support system, have a go before the aircraft difficult to adapt to regional and environmental perform the task. However, this change in addition to bring technical advantages, but also brought a huge change in the aircraft structure. Greatly reduced due to removal of a randomized pilot volume at the same time, the UAV would make it difficult what should be reserved for the number of upgrades, in fact, it is uncertain whether the unmanned aircraft in the future the manner in which development? What future technology can be used for upgrading the performance of the UAV? These problems is difficult to solve like the U.S. UAV technology overlord. Therefore, at this stage, no one fighter is actually a high investment in exchange for the possible effectiveness of disproportionate symbolic success, in exchange for almost no headroom “disposable equipment”, this development of ideas is no doubt with the right fighter The thinking runs counter to.
At present, even though China is stepping up its R & D F -20 fighter, and the exposure of the so-called “dumplings machine also speculation that the Chinese are simultaneously developing two new stealth fighter, but can not be avoided, the Chinese in terms of fighter’s aerodynamic design, or stealth technology R & D, compared with the United States and Europe there is a certain gap. In this case, it is difficult in a new generation of aerodynamic layout has not been very much at home on the fifth-generation fighter, hastily developed unknown inputs and technical risks to high-end unmanned aircraft this big dream and equipment, which is undoubtedly contrary to consistent, prudent and rational arms development thinking. From the strategic perspective, the U.S. R & D X-47B in order to enhance the offensive capability of its navy. For China, it is not only the Navy, even though their overall strategy, mainly to defensive operations in the foreseeable period of time, similar to the X-47B of this too strong offensive nature of the utilitarian equipment needs and not obvious. Therefore, care should be taken to develop high-end unmanned aircraft, now seems to mimic the X-47B research and development, before the key technologies to enhance national strategy toward, you should try to stay in the level of primary technology research and development and technological accumulation.
Third, China should be alert to the United States to the UAV to open bilateral arms race .
the history of the development of military equipment, a timeless truth: success depends entirely on the equipment this equipment can meet the demand. Many points preconceptions that the needs of the so-called demand here is a battlefield. However, the Cold War, the Soviet Union has repeatedly release carrier false information, even through frequent technical improvements of the aircraft carrier after the first nuclear-powered aircraft carrier “Enterprise” service (a lot of technical improvement is conducive to enhance the performance) the Soviet Union not only had exposure to the United States is bound to carrier arms race in the upper hand, and the United States demonstrated a real aircraft carrier performance information to make the development of the Soviet aircraft carrier twists and turns. The United States through such equipment as a means of deception, not only the Soviet Union caused the collapse of the arms race and the USSR After a laborious development of armaments, the results obtained are quite limited. In view of this, when the United States come to realize that by rendering the aircraft carrier value is difficult to make the bait, its very likely to turn to the UAV field, as in the real world, in China and the United States a great market this equipment, and China into an unfavorable arms race is bound to itself.
of equipment, technology speaking, the UAV is indeed more than the aircraft carrier is easy for potential opponents on board the pirate ship of the arms race. The reason is simple, on the carrier, whether it is the development of the aircraft carrier itself or the formation of carrier-centric task force, we need a large number of inputs. Therefore, the input of funds on the aircraft carrier is difficult to be taken by the construction of aircraft carriers and the construction of supporting ships, two basically the same as on the amount of the huge cost of composition, for the savvy countries. UAVs. Only UAV itself, its R & D costs compared to the carrier undoubtedly be much lower, but the key is in the chain of the new military system, unmanned aerial vehicles is a new part of decisive significance. This means that with the arrival of high-end UAV with a large number of applications, almost all the equipment associated with the need for the technological upgrading of the system, whether it is the technical difficulty of this upgrade or the amount of financial investment, compared to the construction of a new fleet has referred less. Therefore, if in the case of lack of sufficient funds and actual needs support, rashly invested by the United States provoked the UAV as the core of the arms race, then China will suffer heavy losses compared to the then Soviet Union.
with the then Soviet Union, similar to today’s China faces the same dilemma that either the carrier or UAVs, are their own urgent need for equipment to occupy an important place in their own equipment R & D system is inevitable, but at the same time, their own lack of the technical basis of the research and development of such equipment, in the R & D process is likely to be a competitor with ulterior motives led astray. However, it is different, today’s China to that of the Soviet Union do not have a significant favorable conditions, that China is the witness of the Cold War from the Soviet Union in the Cold War failures to learn from experience and, more importantly, China has been there is a clear defense path of development and national interests in the worldwide development of specific plans, and these routes, the degree of coincidence of China and the United States is much lower compared to the degree of coincidence in the United States and the Soviet Union’s. Therefore, the Chinese than the Soviet Union was easier to see through an attempt to provoke an arms race in the United States, to more rational development of weapons and equipment truly meet their needs. Therefore, the U.S. high-end UAVs as a tool to lure China into an arms race in degree of difficulty will be relatively large, but China is no doubt should always be on the rational development of the UAV to maintain adequate vigilance.
