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 .
