grade 1 titanium rod decrease is absolutely no problem

Besides the extensive use of new materials has become a common method of combat aircraft to lose weight . Weight loss in the application of new materials , the use of titanium and composite materials are becoming more mainstream . F-22 titanium and composite materials using the ratio has reached 66% , while the traditional steel and aluminum is less than 20 %. From the recent media reports , China in the development medical grade titanium‍ of aviation titanium is very fast. China's titanium research and development, its performance level , production technology, processes and standards currently have reached the world advanced level. In the processing of titanium, January 18, 2013 2012 annual meeting of the National Science and Technology Awards Conference, Professor Wang Huaming Beijing University of Aeronautics and Astronautics presided over the " large complex plane forming an integral member titanium laser technology" First State Technological Invention Award Award. This means that China has become the country after the United States , the world's second master aircraft titanium alloy structural components rapid prototyping and laser technology . And our country is better than the United States has been able to produce laser forming titanium components, to become the world's only master laser forming titanium large main bearing components manufactured and put into practical country. China 's J- 15 if they can embody innovative design features to minimize the weight of the structure , while a large number of new applications aviation titanium and other materials on the materials, coupled with the country already have some basic composites, the empty weight of the F -15 to achieve the decrease is absolutely no problem.

Followed in the avionics field . With respect to the former Soviet Union , China 's electronics industry is rapidly catching up the world advanced level . On airborne fire control radar, China 's J-10 , J- 11 has been equipped with multi-function pulse Doppler radar , according to media reports more new F-10B fighter equipped with phased array radar. Since China on phased array radar transceiver components and VLSI technology has made ​​great progress , so the F- 15 airborne radar in terms of fully capable and " Super Hornet" in the same grade , and can even reach gusts M level. And in the past and have been complex and cumbersome Soviet fighter cockpit flight instruments compared to China's large fleet of three generations of fighters have installed a large number of multi-function displays, and even spend a color LCD display. In the CCTV program " Face to Face" , some users have found that the J-15 cockpit simulator there are at least three multi-function display . It should be said , the F -15 cockpit whole technical level , although not comparable with the F-35, but reached the level of M Super Hornet is no problem .

So now we have to judge the performance of the J-15 , "and the Russian Su-33 , the United States and other world serving the main carrier-based F/A-18 fighter comparable " is not mere propaganda but has real technical basis . But now a lot of point of view, the F -15 flying leaps slippery way , there are inherent deficiencies , limiting the J-15 multi-purpose aspects of sea attacks on the performance of the ground . Well, J-15 can not be converted into a catapult off?

Jet aircraft carrier aircraft flying leaps off the slide to eject the world seems to be no precedent . But that does not violate the basic laws of modern aircraft design . Generally considered to catapult off part of the landing gear strengthened, while flying leaps slip you do not need ; And both need to block cable landing approach , the structure of the body and therefore must be strengthened to cope with the huge impact landing brought . medical grade titanium alloy‍ It can be seen to be modified F- 15 catapult takeoff , it is necessary to increase the weight . After some calculations , now converted catapult takeoff F -15 to strengthen the landing gear may have to gain weight 300 kg . This strict control of the empty weight of the J-15 , it is not good news . But also with a view of the F- 15 converted into the catapult can also lose weight, because the original slide flying leaps in order to improve the performance and design of low-speed flight -lift devices, such as the F -15 canard , etc. , you can catapult takeoff under way canceled. Thus , compared to calculate the modified F -15 increasing weight can be controlled at 200 kg. And in the " face to face" program, many users found that the F -15 landing gear " very thick " , so some people do have to determine the J-15 loaded catapult take-off "program ." Catapult takeoff can further increase the F -15 fully loaded takeoff weight , thereby increasing the fuel load and the F -15 weapon mount capability, which has a very large significance for the F- 15 aircraft carrier battle groups to improve their performance .

Thus, " an airplane out of a series of development is certainly , then this series to a certain extent , there will almost certainly be the next generation of aircraft arrangements ." We should SUN Cong chief architect of the program, said these words , be depth thinking. Some people may think that the development of the J-15 ejection type of equipment requires China has an aircraft carrier catapult , it is definitely not happen overnight. So at this time, why the Chinese J-15 efforts, not as a direct development of a new generation of stealth aircraft carrier .

But in fact , the Air Force and Navy air combat styles are very different . titanium grade 1‍ Air Force Materiel fourth generation fighter is without a doubt the king . However, naval equipment , the development of fourth-generation stealth aircraft is even more complex, and the status of three generations of heavy machine also more than we thought it would be stable .

grade 1 titanium rod China laser forming of titanium alloy components than the U.S.

  Recent CCTV program " Face to Face" on the F -15 had an interview with the chief architect of Sun Cong , which disclose a lot of important information about the "Flying Shark" developed . Which CCTV reporters Cong Sun , also spoke in particular of the " next generation of aircraft should definitely have plans ." This makes the future of China 's military enthusiasts carrier aircraft and more full of expectation . medical grade titanium‍ But we are looking forward to the second generation of domestic aircraft carriers , while the J-15 may wish to present a more objective and comprehensive understanding. Chinese aircraft carriers in the process of development, the J-15 is by no means merely a platform to meet the initial landing of aircraft , more than those who were later replaced by the short-lived "third generation fighter " , but to be in a long-term process the main role of an offense and defense .

November 2012 , CCTV reported during the first carrier-based aircraft taking off and landing aircraft , the F -15 is so introduced : a successful landing on the Liaoning number of F- 15 fighter , is China 's first self- designed and developed carrier -based multirole fighter , with completely independent intellectual property rights , it has a combat radius , mobility, payload and more features ; according to different combat missions, carry multiple anti-ship missiles, air to air missiles, ground missiles and precision-guided bombs and other precision strike weapons , with full sea , the whole airspace strike capability. The performance of the J-15 , Su-33 with Russia , the United States and other world F/A-18 main carrier-based fighter comparable active , so as the ferocious powerful air "flying shark ."

SUN Cong in the CCTV program " Face to Face" is the definition of F -15 : J-15 is the first generation to produce air -based multi-role fighter of our country, should belong to the third-generation fighter , the difference is such a difference , it China 's aviation started quite late , but the starting point has the advantage .

To produce a space-based multi-role fighter , the J-15 is a qualitative judgment. In "Face to Face " program commentary revealed that the F -15 F -11 fighter is based on the development of our own production , the assembly has canard , folding wings , tail hook fitted with stern features , such as carrier-based aircraft , high gear strength. As we all know , J-11 is a twin-engine heavy " air superiority " fighter , so on the basis of its research and development of the F -15, in the fight for control of the air have certain advantages. Russia's Su-33 also reflects this feature , from the indicators, the Su-33 in addition to weight ratio on behind the Rafale M, while basic and F/A-18E and Rafale M flat in other areas, and the Soviet Union - the weight ratio to more than 33 Super Hornet , medical grade titanium alloy‍ so the air combat capability to more than F/A-18E.

But it is generally for the Su-33 combat performance is not good, because the Su-33 is the first empty weight too . Su-33 's empty weight reached 18.4 tons , more than the F/A-18E of 13.4 tons , is much larger than the "Rafale M" of 9.7 tons . This means that the Su-33 payload and fuel takeoff in carrying amount will be relatively limited, which limits the performance of the Su-33 in combat . Followed avionics relatively backward . Su-33 avionics basically behind the F/A-18E fighter 10-15 years. With the United States has a strong F/A-18E avionics base , which has better avionics and man-machine interface , which make up the gap with the Su-33 's flight performance alone . U.S. aircraft carrier battle group plus the warning means , the actual combat "Super Hornet" instead of pressing the Su-33 to play .

Therefore, it is very similar to the evaluation and control of the air performance of the J-15 Su-33 , but also to see whether it can solve these two major problems. The first is the weight loss. Modern fighter to lose weight, there are two ways nothing less . The first is to optimize the design , and the second is the use of new materials. Former Soviet Su-27 design fully embodies the idea of ​​weight loss . The use of more than 60% of aircraft aluminum , due to the widespread adoption of integrated structural system layout , the overall , integrated structure and layout , structural design partial rationalization to reduce the structural weight . The Sun Cong also mentioned in the CCTV interview : " weight loss is a very complex work , if at first you load the design, the structure of this design dexterity , the efficiency of the structure is in the selection, titanium grade 1‍ and so on. other to achieve reduction in weight of the final series . "

alloy medical titanium Difference titanium, aluminum

Titanium and aluminum are essentially different , titanium grade 1‍ but sometimes they are just like some of the products , it is not difficult to identify them carefully observed , particularly titanium magnesium alloy doors and aluminum doors , details about the specific distinction below :

    1, the titanium added to the titanium- based alloy medical grade titanium‍ other alloying elements called titanium . Titanium has a low density , high strength , corrosion resistance , good process performance , etc., is an ideal aerospace engineering structural materials. Titanium and titanium alloy structure can be divided into heat titanium, titanium alloy , or α , β , and α + β type titanium alloy titanium alloy . Study also include forming technology of titanium alloys , powder metallurgy technology, rapid solidification technology , titanium military and civilian fields.

    2 , aluminum is aluminum made ​​by adding some alloying elements such as aluminum - manganese alloys, aluminum - copper alloys, aluminum - copper - magnesium-based hard alloy, Al - Zn - Mg - Cu based hard alloys. Aluminum has a better than aluminum physical and mechanical properties : easy processing , high durability , wide application , good decorative effect , rich color . Rust-proof aluminum into aluminum, hard aluminum , hard aluminum and other types of various types have their own range , and have their own code , in order for users to choose.

    3 , remains a lightweight aluminum features, medical grade titanium alloy‍ but significantly improved mechanical properties . Application of aluminum alloy has the following three aspects : First, as the force components ; Second, as doors, windows , pipes, covers, shells and other materials ; Third, as a decorative and insulating material . After the use of aluminum anodized characteristics can be colored , made of various decorations. Aluminum alloy sheet, the surface profile can be corrosion, ginning , painting, printing and other secondary processing to produce a variety of decorative plates, profiles, as a decorative material.

titanium sheet How to distinguish a titanium frame

Titanium material found

Development of titanium materials: a German chemist in 1794 ( two hundred and seven years ago ) discovered this new metal element and named it titanium titanium. Named by sources from the ancient myth of the West Prince Titan ( Titan ) , because he titanium bar for sale believes that super-strength titanium and ultra- refractory degree , working with the great Titan with shine .

Although titanium material in the Second ○ was discovered seven years ago , but due to refining process was not easy ( titanium is very easy to combine with oxygen ) , scientists have been unable to be refined into useful substances metals. Until 1938 , DuPont developed a new way to extract , plus magnesium reduction method, the red and gold reserves in the ground ore , after chlorination, plus magnesium , restore it and become a sponge titanium, to a ninety-four three years , DuPont began producing a large number of titanium metal products.

Development of titanium frames

Titanium is a metallic chemical element , because the refining process is not easy, and less expensive titanium material production , it is only used in the early titanium aerospace science , marine science and other high-tech science and energy development . And daily necessities are to begin in 1965 applied to the titanium material .

The first titanium frame is in九八○年someone invented the " rivet -like titanium frames " titanium welding is a very difficult material, there is no better way to do early connection handling , use rivets type of way to put it nailed together. While in 1981 , the plant began buy titanium sheet outside coated with a layer of nickel titanium material to facilitate welding. An increasingly competitive market and month of the new manufacturing methods , 1982 Day MARUMAM company pioneered the first payment in full titanium metal frames around the world ; 1984 also has factories launched nickel-plated titanium frames , there is a big price difference .

Material development of titanium

1 . Full titanium : Frame in addition to the screws and plastic gloves for outside , all metal parts made ​​of titanium material .

2 . Nickel titanium package : Borders titanium material, the surface material using a nickel package , and now this frame no longer exists.

3 . Assembled Titanium: Due to the high cost of production of nickel and titanium package to update the device , it is not updated before , assembled titanium frames as the situation , but this product is dangerous because each metal has a different melting point, literally Putting it together will be very fragile. Early nickel- titanium frame package passes flattened angle , it 's not like a factory original border distribution of production so mean , so after use , nickel, and titanium -coated layer that will break out and no way to weld repair , titanium also includes assembling such a situation .

4 . Nickel-plated titanium : In order to reduce costs, make it easier on the production, but also come up with a factory nickel plated titanium . So then processed using conventional welding techniques .

How to distinguish between pure titanium frame

1 Check the weight.

2 Check magnetic reflection.

3 Check the hinge structure .

4 with a chemical reagent checked.

5 Test conductive index .

We can be a magnet placed on the table , then leaned over the frame , if it is not generating the magnetic response of titanium frames . Also check its hinge , titanium glasses are placed two plastic or metal liner in the hinge , in addition , because of different titanium round bar metals with different electrical conductivity , so with conductive index can be measured whether the titanium metal.

Now consumers in addition to care about aesthetics , but also pay great attention to security , such as European countries have regulations, things come into contact with human skin items ( such as glasses , watches , necklaces , etc. ) , if necessary ingredient containing nickel marked . Because the nickel whites sometimes cause skin lesions or skin cancer , so manufacturers and stores have a duty to inform .
