The deep winter in Northeast China was already cold, but for some reason the Northeast in January 1989 was even colder than before, and dripping water into ice was no longer a kind of ridicule, but a real fact; however, it was in such a season of nine cold days, the military factories under the Northeast Heavy Industry Group were still roaring with machinery, and the scene in full swing seemed to dispel the cold, which made people feel warm at a glance;

In the past half a year, thanks to Lu Jiadong's strong rectification, the efficiency of the Northeast Heavy Industry Group has been greatly improved, originally could only ask grandpa to tell grandma to rely on the machinery hall, the days of the Agricultural Machinery Bureau to get orders are long gone, now not to mention the mechanical bureau orders to the back row, even the orders of the Ministry of National Machinery are no exception, because the current Northeast Heavy Industry Group produces civilian parts, priority for export to earn foreign exchange,

Because Lu Jiadong, as the helmsman of the group, during the period when he was a trapeze, he not only vigorously promoted the new air defense missile system to the outside world, but also introduced the civilian products of the Northeast Heavy Industry Group to foreign countries, especially the Arab countries with an underdeveloped industrial base and strong funds;

Thanks to the good relations established by the joint development of the new air defense missile system, Saudi Arabia has given great help in this regard, not only purchasing more than 60 million US dollars in one go for special spare parts needed for oil exploitation, but also actively promoting and introducing them to other Arab countries, formally taking advantage of Saudi Arabia's influence, the United Arab Emirates, Egypt, Kuwait and other countries have purchased a certain amount of civilian products from the Northeast Heavy Industry Group, so that the total sales have exceeded the $100 million mark;

Such a huge amount of civilian product turnover, in the Northeast military industry enterprise civilian production history is the first time, the news came that the whole group is boiling, the production line that has not been seen for a long time is running at full capacity and three shifts are also here in various production workshops, and with the increase in the export performance of the Northeast Heavy Industry Group,

After all, in that era, the export enterprises were synonymous with quality and reputation, and the potential for cooperation was unlimited, so countless orders rolled in, and its production volume was even ranked in the following year........

The increase in production and sales performance, naturally led to the welfare of workers has also risen, the original monthly less than 100 yuan of ordinary workers, now plus a variety of benefits and corresponding rewards, casually can get four or five hundred yuan, with technology to get higher, in general, its income level and the coastal open area of the joint venture factory is only high;

This makes the workers of the Northeast Heavy Industry Group work harder while straightening their waists, even if Du Bing and others, who were extremely unserious at the beginning, are also working hard, for fear of being overtaken, you must know such a high salary, such a good welfare treatment, not to mention that in the current Northeast, even the whole of China is difficult to find with a lantern.

Because of this, the vitality of the Northeast Heavy Industry Group has been renewed, and you can feel the excitement of a brand everywhere you go, of course, the employees of the group will not forget the young helmsman who brought them this happiness when they enjoy this happiness.

Whoever talks about him will have a look of great reverence on his face, and now this young man is still busy, only this time, he is not only for the better life of the workers, but for them to restore their dignity, a kind of dignity of the eldest son of the republic............

"Due to the need for increased technical and tactical tasks of the new air defense missile system, we have revised and improved the program.........

At this moment, Tong Wenlie, the chief engineer of the project, is standing in front of the flickering slide projector, and uses the guide rod to draw a circle on the two sides of the bomb wings of a fine anti-aircraft missile engineering model on the curtain:

"Due to the expansion of the mission, we have adjusted the aerodynamic layout of the missile, specifically from the original cross****** to the beveled long side strip wing, the reason for such a change is mainly based on the following points:

First of all, as a medium-range air defense system, the new air defense missile has a large range and firing height, and the required engine is relatively long, and when the charge of these engines is burned, the center of gravity of the whole bomb shifts to the direction of the warhead, and then the stability image of the missile is very large, and the maneuverability is relatively poor..........

As he spoke, as soon as the remote control in Tong Wenlie's hand was pressed, the slide projector rotated, and the picture of dissatisfied data and structure diagram appeared on the screen.

As a medium-range air defense missile, the flight speed of the new air defense missile has a large range of changes, which can range from zero to Mach 3~4, and the flight altitude changes greatly, climbing from the ground to more than 10 kilometers high;

If conventional wings such as trapezoidal wings or ****** wings are used, the lift weight of the missile will change greatly with the difference of speed and altitude, while the position of the lift center of the large side wing in different speed and altitude ranges changes very little, which is conducive to improving the static stability of the missile and thus improving the maneuverability of the missile. ”

After speaking, Tong Wenlie paused, and then looked at Lu Jiadong who was sitting on the side, at this moment Lu Jiadong's eyes also came, and under the four eyes, Lu Jiadong just smiled meaningfully, but Tong Wenlie showed an indescribable admiration..........

Speaking of this set of large side wing aerodynamic layout improvement, in fact, it was not his first initiative Tong Wenlie, but by Lu Jiadong first proposed, and improved, he just improved and verified on the basis of it, for the results achieved, Tong Wenlie is very happy.

Because the aerodynamic layout of this large-sided air defense missile can be called the first in China and fills a number of domestic gaps, Tong Wenlie, who is ready to further improve academically, wants to write this achievement into a paper and publish it, so he found Lu Jiadong and prepared to co-author it with him, after all, this achievement is not his alone;

But when he explained his intentions to Lu Jiadong, Lu Jiadong not only refused without hesitation, but also handed over the entire technical achievements to him like a daily gift, which made Tong Wenlie a little surprised, and he didn't understand why Lu Jiadong was like this, but the answer Lu Jiadong gave him moved him:

"The purpose of engaging in weaponry is to build the backbone of the country, to consolidate the foundation of the country, and to do a good job is no less meritorious than the crime of fighting the country; and if it is not done well, it is no less guilty than the crime of treason. Whether it was in Wanshan in the past or now in the Northeast, I like to do it bit by bit, not because I don't want to make a name for myself and be an authority, but before our national army is truly modernized, I don't want to scatter all my energy, as the so-called giving must be gained, there must be a beginning and an end, I don't want any authority and fame, what I want is a straight and strong national backbone.........."

Hearing this, Tong Wenlie can be said to be ashamed of himself, and secretly blamed himself for this for several days, and finally learned from Lu Jiadong to put down the matter of publishing papers, and devoted himself to the development of a new air defense missile system..........

Chaotic thoughts flashed in Tong Wenlie's mind, and then he picked up the teacup and moistened his throat, then pressed the remote control again, and then a louder voice sounded again in the room:

"Secondly, the new anti-aircraft missile has strong mobility, and the large side strip wing can have a good strengthening effect on the structure of the missile body, just like adding four very long stiffeners, which can improve the rigidity of the missile body structure, that is, it can make the missile body stronger;

Finally, and most importantly, due to the expansion of the tasks of the new anti-aircraft missile, in addition to the interception function of the combat aircraft that was just formulated, the interception capability of air-to-ground missiles, cruise missiles and other low-altitude aircraft has also been added, so this requires the new anti-aircraft missile to have excellent maneuverability, and in order to improve the maneuverability, it is necessary to increase the lift, and the large side strip wing has an irreplaceable role in this regard;

At the same time, the missile needs to accelerate rapidly after launch, so as to approach the target as quickly as possible and destroy it, so it needs to have good low-resistance characteristics, the supersonic resistance of the large side strip wing is small, and the characteristics are good, all in all, after verification and calculation, the aerodynamic layout of the large side strip wing is suitable for the overall needs of the missile, and the similar aerodynamic layout is also adopted by the United States' 'standard' missile, the Soviet Union's 'Beech' missile and Europe's 'Aster' missile, which can be said to be a result of different paths........."

After listening to Tong Wenlie's introduction, all the experts present nodded in agreement, and then Tong Wenlie explained the semi-active radar seeker, prefabricated fragmentation warhead, single-chamber double thrust technology, pneumatic rudder surface with synchronous gas rudder and universal vertical launch technology of the new air defense missile, until finally after glancing at the relevant experts, Tong Wenlie cast his eyes on Lu Jiadong and asked slowly:

"Mr. Lu, what do you think needs to be improved in this plan?"

"There is no big problem with the missile body itself and the launcher, but in terms of radar surveillance system, I think it has not included the current threats, especially the latest air threats, so it has not achieved full coverage of the target..........

As soon as these words came out, the audience was stunned, you must know that the current set of plans is already the most complete, and the targets to be dealt with have been included in both aircraft and missiles, and basically all that can be thought of can be thought of, how can there be omissions, and it is also the so-called new threat in the air............
