■ Express reporter Zhou standards
Zhuhai Airshow display of the Long March V rocket, which is China’s first public appearance of the moon rocket. Reporters learned yesterday, the Long March V, 2014 or carry Chang-e fourth satellite to the moon.
along with the Chang-e II satellite successfully launched and completed a series of scientific tasks, China’s first moon rocket models eventually identified as the Long March V.
carrying capacity to 25 tons
reported that the “five-second” period, China will build the space station, and the implementation of lunar, moon, etc. program. As the current carrying capacity of China’s Long March II rocket largest unable to complete these tasks, it will be capable of transporting 25 tons payload developed a new generation of large load carrier, that is, the Long March V rocket, Long March V carrier rockets, including CZ-5A, CZ-5B, CZ-5C, CZ-5D, CZ-5E and CZ-5F six kinds of configuration.
Zhuhai air show debut of the Long March V 1:10 model. Reporters found that the Long March V rocket Long March II with the biggest difference is the top of the antenna-like escape tower into a cone-shaped. Compared with the existing launch vehicle Long March V rocket carrying capacity of near-Earth orbit from the current 10 tons to 25 tons, geosynchronous transfer orbit from the current carrying capacity of 5.5 tons to 14 tons.
About the Long March V stations before the show: According to China’s lunar exploration goals, CZ-5E has initially been identified as the rocket for the lunar surface sample return mission and the rocket.
were developed and launched in Hainan for
Long March V and the European “Ariane 5″ basically the same level of large launch vehicle, capable of launching 20-ton long-term manned space station, a large space telescope, the return type lunar probe, deep space probes, satellites, super-heavy applications, in new space launch site in Wenchang, Hainan came, therefore, will be launched in Wenchang space launch base, the first The launch scheduled for 2014.
as large launch vehicle Long March V 5 meters in diameter, is difficult to transport by rail or road to the existing launch site, thus requiring the development and launch rockets to be in the same base, just completed in the near Hainan Wenchang Satellite Launch Center in the lower latitudes from the equator close to launch satellite carrier rocket to save fuel. Meanwhile, a rocket off the area within a radius of 10 km in the sea of ??people and less impact on the surrounding environment. Although located in the island, Wenchang largely unaffected by the typhoon. Therefore, the development and launch of the Long March V are selected in Hainan Wenchang space launch base.
Chang-e IV satellite’s main task is to achieve a soft landing on the moon, lunar, Moonlight and other life science and engineering. According to the China Aerospace Science and Industry Group, the staff, the quality and quantity of scientific instruments far more than its “predecessor”, the Long March V carrier rockets will be the best choice.
large aircraft can not now install the “China Heart”
engines still rely on imports, domestic large aircraft project is speed
“to China’s large aircraft flying the blue sky as soon as possible!” Premier Wen Jiabao’s words speak of several generations of Chinese people’s dream.
Indeed, in the current aviation field, the large aircraft were foreign monopoly. However, the good news is constantly passed over. In the first day of the opening of this air show, China Commercial Aircraft C919 for the first time it received 100 orders and ARJ21-700 regional jets in the air show type re-signed 100 orders for the next day, they are taken for the development of China-made large aircraft a big step.
However, whether C919 or ARJ21, their heart – the engine still rely on imports, the Chinese plane in order to install the “China Heart”, still take time.
to build the aircraft was not controlled by others
large aircraft, generally refers to the total take-off weight of more than 100 tons of transport category aircraft, including military and civilian transport aircraft large transport aircraft, but as countries have different levels of development the aviation industry in the country of more than 150 large passenger aircraft is called, 100 the following called regional jets; the international shipping system used on the 300 or more aircraft called the large passenger aircraft.
Premier Wen Jiabao visited a few years ago and CAS academician Wang Daheng two-time Academy of Engineering, 88-year-old Wang Wen Jiabao put forward on the “Chinese people have their own large aircraft.” During the air show, China Commercial Aircraft Company, the official said, the production process involves a number of large aircraft disciplines including aerodynamics, avionics, materials science, from the industrial point of view based on the large aircraft industry, involved in chemical, electronic, metallurgy and other sectors, the large aircraft known as the “flower of modern industry”, is a country in general, the embodiment of strength. In today’s world, only the United States, Russia and the EU can build large aircraft.
development of large aircraft in addition to sectors of the economy, but also improve the defense capabilities of the embodiment. Once you have the ability to build large aircraft will no longer be dependent on imports, war will not be controlled by others.
two years to sell hundreds of small planes stand
in the State Council with the support of the large aircraft project has been included in “Long-term Scientific and Technology Development Plan (2006-2020) “and” national economic and social development in the Tenth Five-Year Plan “, May 11, 2008 China Commercial Aircraft Company was officially established, marking the formal step of manufacturing large aircraft the first step.
2008 年 11 28, the first aircraft developed by China with independent intellectual property rights in the new short-range turbofan regional aircraft – ARJ21-700 aircraft flight test success, immediately favored by domestic and international airlines, In just two years to sign the 240 orders at this air show, ARJ21-700 regional jets in the air show the next day type re-signed 100 orders, total orders so ARJ21 has reached 340.
true meaning of China’s first aircraft large aircraft C919 1:1 model was first exhibited at the Zhuhai Airshow, C919 similar to the Airbus A320, Boeing 737 with considerable. The first day of the air show, China Commercial Aircraft Company and six major domestic and international aviation, finance companies signed 100 orders for large aircraft in the market development has made important progress. With the successful development of C919, C929 and more large aircraft developed into tension among the … … large aircraft is making big strides.
According to projections from now to 2029, China’s civil aircraft fleet will reach 4724, the freighter fleet to 579, which is China’s large aircraft golden age of development.
turbofan engine technology do not break so matching “foreign Heart”
Although the development of China-made large aircraft was stride for, but because of the large aircraft’s core technology – turbofan engine technology has not been broken. So whether it is ARJ21 or C919, can only use foreign engines.
“The quality of an aircraft, mainly to see the quality of the engine!” At the Zhuhai air show at a press conference, a foreign engine manufacturer’s spokesman bluntly. Indeed, the two major international aircraft manufacturers – Boeing and Airbus, have benefited from good cooperation with engine manufacturers. And China to develop large aircraft, engine research and development necessary from the “poor white” of the base on the start, the cost of the cycle is much lower than the aircraft itself, much longer development time, can not stop the big planes had to choose ” foreign heart. ” December 2009, China Commercial Aircraft Company selected the CFM International LEAP-X engine, as the C919 single-aisle aircraft.
Airshow display Taihang engine’s “Chinese heart” family, all military aircraft of the “heart.”
openly anti-missile weapon out
made four air defense system, capable of attacking targets in the air eleven combat
this air show, China Aviation Science and Industry Group debut four air defense system that can hit incoming targets in the air eleven, including fighter jets and high-speed low-altitude flying raid to the missile, to build its own missile defense systems.
the principle of anti-missile missile is extremely complex, only the United States recognized the world series of Patriot missiles.
four air defense system missile
air defense system is a set of command, control, communications, intelligence, reconnaissance and combat operations in one system, the main surprise attack against enemy fighters and high-speed flying missiles. At the Zhuhai air show, China Aviation Science and Industry exhibit a complete set of four air defense system: the satellites and early warning aircraft that struck the help of aerial targets, the first to use long-range missiles to intercept FD-2000, once long-range interceptor was a breakthrough, enabling the second layer of defense, KS-1A missile launch to intercept; Once the break two enemy targets at low altitude defense, then immediately enable a third layer of defense, the use of FM-90 missile interceptors, and if the enemy broke through the three-goal defense, the last use of anti-interference ability of FL-2000 missiles.
China Aviation Institute of Science and Industry Group, the second chief engineer Xu Gang told reporters, in addition to this set of four air defense system against incoming fighters, but also for high-speed interceptor missiles flying, especially or surface-to-ground missile is a missile, the missile has a good effect, from this perspective can be seen as anti-missile system.
anti-missile missile launch vehicle
four air defense system can build a dense air defense network, it is worth mentioning that these four can board the missile launch, mobile and not easily eliminated at this air show on display at the missile launch vehicles, launch vehicles is only the smallest pickup truck models, you can quickly reach the designated launch site, but also to leave quickly after launch . FD-2000 anti-aircraft missiles S-300 missiles in Russia’s improved, the maximum range of about 100 km, bomb weighing 1.3 tons, using a passive seeker, mostly used by the Army-type vehicle, a missile launcher, a target guided radar vehicle and a search radar vehicle can be completed. KS1A China-made air defense missiles, air defense missiles, the maximum range of 50 km using radar shape similar to the U.S. “Patriot” missile system uses phased array radar, with multi-target tracking, multi-target attack capability. FM-90 air defense missiles in the air show in the first live show, its maximum range of 15 kilometers, can be effective against aircraft, helicopters, unmanned aerial vehicles, cruise missiles, tactical missiles and air to ground anti-radiation missile many types of air targets. The FL-2000 air defense missile a maximum range although only 6 km, but its low-altitude, low altitude flying fixed-wing aircraft, helicopters, unmanned aerial vehicles and cruise missiles with a strong lethal target class, in the case of battle damage , can be removed manually launch the missile.
anti-aircraft “Three Musketeers”? Is misreading
this air show debut of the coastal defense system structure chart, the chart shows three missiles against targets based on heavy-duty aircraft carrier battle group as the core surface for Many media interpreted this as our anti-aircraft “Three Musketeers” coming out. Air Science and Industry yesterday in the third chief engineer Yan Lixin researcher said that this is actually a misunderstanding.
Yan Lixin, the “Three Musketeers” in the previous air show also exhibited, but not systematically to three missiles and coastal defense systems linked to this air show is the first time anti-ship coastal defense missile systems to link with the whole, show a complete operational system. Indeed C602, C705, C802A three missiles hit the enemy has the ability of large ships, but within range, the C602′s longest-range missile a maximum range of about 280 km. “The real combat during the enemy attack and defense can be, ah, the power of its defense than I am strong, I can not hit him.” Yan Lixin, this seems like shooting two people toward each other, one of the wearing vests, then he may be right, wearing bullet-proof vests for the dead.
