"Mr. Yang, I think we can start talking about new orders, we and Baba Yang will purchase at least 200 J-15s and related supporting weapons and equipment this time, and we hope that Huake Airlines will establish a production line for fighter jets and missiles in our two countries. ”

The next day, both Jarad and Nimhera found Yang Jie.

“……”

For such a quantity, it is definitely something that Yang Jie did not expect, in his estimate, the number of people purchased by the people of the Rest Country will not exceed eighty after upgrading forty-five big Tomcats, and what surprised him is that the Rest Country will purchase at least two hundred planes together with Baba sheep.

The surprise was not over, and when Nimhela turned to leave, he told Yang Jie, "We are already in contact with the Argentine side, and we will carry out joint purchases, and if the price is right, maybe this quantity will be even larger......

For such news, Yang Jie really couldn't react for a while.

The number of orders for more than 200 aircraft plus the number of orders from the domestic military is at least about 300 aircraft, which is a business of more than 9 billion US dollars, which is enough for Huake Aviation Technology Company to produce for several years.

"What, joint purchasing? How is this possible!"

Zhang Haiping and others were also quite surprised by this news, the two countries of Anxiguo and Baba Yang were a little discordant on the border issue, and now they are joining hands to purchase fighter jets, presumably to lower the price of fighter jets.

"It looks like they want to drive down the price of this fighter, what do you think?"

Zhang Haiping looked at Yang Jie and asked.

"As long as the military agrees to their demands, we at Huake Aviation Technology Company have no problem. ”

Yang Jie opened his mouth and said.

"As long as you don't violate the arms export regulations, the military will not interfere in this. ”

Zhang Haiping said.

In the next few days, Baba Yang and Anxiguo also negotiated with Huake Aviation Technology Company, and Huake Aviation Technology Company naturally had a working group responsible for the specific negotiation content.

After bargaining, the price of this J-15 was finally set at 26.25 million US dollars, which is equivalent to a two-and-a-half discount on the previous price of 3,500 US dollars.

This price is also Yang Jie in order to thank the rest of the country to provide two F-14 to Huake Aviation Technology Co., Ltd. for research, and also get the favor of hard pipe refueling system system technology, Huake Aviation Technology Co., Ltd. produces 50% of the order, and the rest of the orders will be completed in their respective domestic production lines.

Both Baba the Sheep and the Sabbatical State were very satisfied with the price and signed the contract.

A few days later, Zhang Haiping inspected Huake Aviation Technology Company, Zhang Haiping was extremely concerned about the hard tube refueling system of Huake Aviation Technology Company, and also came to the laboratory where this system was developed.

"This is the in-flight refueling docking structure you developed?"

Zhang Haiping looked at the built-in oil receiving device in front of him with a diameter of half a meter and a height of about one meter, and his eyes were also shining.

"Yes, this is a built-in oil receiving device jointly developed by us and the Jinshan Aerospace Technology Research Institute under the China Aerospace Corporation. ”

Yang Jie said with a smile: "Jinshan Institute of Aerospace Technology has been developing space docking structure, which has a very solid foundation, and this technology can also be applied to air refueling technology, and the company also took the initiative to find them to develop this aspect." ”

In fact, China has long been preparing for space docking technology, because astronauts need to enter and exit the cabin in space, which requires that the gas in the relevant cabins cannot leak, and the cabins must be tightly closed between the cabins.

The 12 docking locks of the space docking structure developed by Jinshan Academy of Aerospace Technology are the key components in the docking mechanism, and the lock hook must be synchronized locking and synchronous separation, which is like "screwing" in space.

The docking mechanism itself is also more complex than the fuel filler, because there is no air resistance/damping in the space, and the relative kinetic energy needs to be absorbed through the docking mechanism, otherwise either the two aircraft will bounce off or forcibly lock and cause non-convergent vibration resulting in damage to the docking body.

After docking, the energy and control of the docking body may also need to be merged and managed, which is also much more troublesome than air refueling, and the research institute and Jinshan Jiaotong University have compiled more than 1,000 kinds of procedures in order to deal with all the possible docking situations of the docking and docking.

The docking lock of the refueling device does not need to be so complicated, and the refueling truss of this set of hard pipe refueling copied and upgraded by Huake Aviation Technology Co., Ltd. is equipped with a V-shaped operating surface in the middle, which is similar to the elevator of the aircraft, and the refueling truss can be moved within a certain range by manipulating it.

With its profound technical skills in material technology and pneumatic layout, Huaxing Group has successfully imitated this set of hard pipe refueling device, and has carried out technical upgrades, with a higher degree of automation.

Because the fighters in the country are now hose refueling equipment, a hose refueling equipment is installed on the tanker.

For example, the hard pipe refueling device on the fuselage of the fighter was developed by Huaxing Group Company itself, and Huake Aviation Technology Company and Jinshan Aerospace Technology Research Institute carried out joint research and development.

The docking lock is designed by Wang Jianqi, a senior engineer of Jinshan Aerospace Technology Research Institute, at the beginning of this set of devices had the problem of synchronization coordination of the docking lock system, and it took almost half a year to find the crux of the problem - the lock hook is driven by a steel cable, and the steel cable will become longer and the tension will decrease under large loads, which leads to the fact that the lock hook cannot be unlocked synchronously.

The technical team has made targeted improvements, and now it is a technical problem that has been solved in one fell swoop, and now the docking lock system of flexible transmission is not only quickly and accurately adjusted to synchronization, but also makes the life of this subsystem have been greatly improved.

Through rigorous fatigue life tests, this subsystem can be used more than 100,000 times, and a fighter jet is almost not repaired and replaced after loading.

In fact, the rabbit military in the nineties on the rest of the country's big Tomcat fighter got hose refueling technology, but the technical degree of the hard tube refueling system is really very difficult, this time Huake Aviation Technology Company once again imitated and upgraded, can be regarded as a complete technology.

Zhang Haiping and others were also in a medium-sized wind tunnel laboratory built by Huake Aviation Technology Company at a cost of more than 40 million US dollars.

At this time, a reduced version of the F150 model was placed at the mouth of the wind tunnel, with a set of hard-pipe refueling equipment at the tail, and a model of the J-15 was also placed behind.

At this time, a strong air flow was sprayed out of the tunnel mouth, and when volatile alcohol was sprayed out of the tunnel mouth, the white air flow produced various white vortices along the body and wings of the tanker aircraft, and the sensors on the body also recorded various parameters.

In order to grasp the distance and range controlled by the tanker and the various fighter models behind it during refueling, Sinoking Aviation Technology Company had to do many wind tunnel tests, during which these models had to be blown from different angles.
