R & D status Titanium

Relative titanium sponge, since the development of aerospace technology, has been very active in research and development of titanium. From basic research to study properties of the alloy, to applied research have made great progress.

Basic research, interstitials impact strength and bulk modulus of titanium research, composite interface behavior finite element simulation study, ordered alloy strengthening research, alloys interaction of atoms and vacancies, etc. have made progress. In order to meet the performance requirements of applications in different fields of titanium wire manufacturers, alloy design display space, with remarkable results. Used in aerospace field BT 3 7 alloy, NI N CT 2 0 alloy, NI NT i a 600 alloy, T i a 60 alloy, "I T1 5 D alloy, NI NT i a 40 alloy, NI NT i a 26 alloy, and NI N TP a 650 alloy is representative of the new grade alloy materials research at home and abroad in recent years, to meet the different components of the material application performance requirements, and some can reduce costs, reduce quality study of high temperature titanium alloys (such as T i 5 3 3 1 1 S) is also a hot spot [16]; apply to ships in the field of T imeta l 5 1 1 alloy, NI NT i -B 1 9 alloy and NI NT i have a 91 alloy significantly improved in toughness, corrosion resistance and sound transmission, etc., for large ships (such as aircraft carriers) manufacturing and marine industry has a positive role in promoting development in the biological field mainly uses Z r, N b, T a, P d and sn as grade 1 titanium wire element to enhance the mechanical properties and biocompatibility, such as T i a 3 5 Z r - l ON b alloys and T i a 2 9 N b a 1 3 T a a 4. 6 Z r alloys, etc. In recent years, the development of bone material, Tsinghua University is a typical representative of the biological field applications. civilian areas widely used a golf club called KS -T il 9 grades of alloy, making the cost of a substantial decline, quality.

In recent years, due to the promotion of civilian titanium, titanium applied research in the construction, automotive, marine engineering, medical, and sports and other aspects began to increase, especially in the field of application of desalination has attracted wide attention, medical titanium 1, C 2 0 ( T i a 6 A 1 -7 N b) the products have been in clinical use.

titanium spring wire So now we have to judge the performance

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 titanium welding wire 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 . 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 titanium spring wire 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 . Air Force Materiel fourth generation titanium wire manufacturers 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 .
