Super military empire

(Something happened at home. I can’t do it on the 22nd. I’m sorry, my brothers. I’m going to have these two updates today. When things are done, I’ll choose the time to update!)

"How much funding is lacking?" Liu Yijiu asked directly."After the funds are in place, when can the experiment be carried out? In addition, the Americans use a hard tube refueling system. This kind of refueling system is technically difficult and complex. Can we produce it?"

Every question Liu Yijiu asks is the key.

He still knows a lot about the tanker.

Otherwise, he would not have been without any urging.

"At present, imitating the American hard-tube refueling system. Due to our lack of processing and design capabilities, we are not using Boeing’s own hard-tube refueling system, but using hoses that are less technically difficult. Refueling system..." Seeing Liu Yijiu's brows frowned, he explained quickly, "Of course, the work of imitating the hard tube refueling system is ongoing."

"How far is it going?" Liu Yijiu didn't care about the hose refueling system at all."The hose refueling system is easy to operate and simple in technology, but the refueling speed is too slow. It can only be used for refueling fighters with high maneuverability and low refueling capacity. At present, our bomber has a short range. , The combat radius is also small, and the range of transport aircraft is not long enough. If you want to conduct long-range operations, you must also refuel in the air..."

What Liu Yijiu said is indeed a fact.

The Republic currently does not have long-range bombers. Even long-range bombers, like the Vulcan with a combat radius of more than 3,000 kilometers in the Anglo-Arab war, are used to bomb Argentina, and require a larger number of Vulcan-modified aerial tankers to refuel. Air bombing of Argentina.

The Republic’s H6, without improvement, even Vulcan’s combat radius cannot be reached.

"Not only that, we need to refuel, but also helicopters, large transport aircraft, etc. Refueling methods such as hose refueling are simply not appropriate!"

Since the world’s first aerial tanker and its birth in the United States in 1923, the role of aerial tankers has become more and more important, especially when the aircraft performs long-range and ultra-long-range missions, it is unparalleled.

The hose refueling system was born in the first place, and this kind of aerial refueling method is used in the world's major powers.Although the technical structure is simple and easy to disassemble and assemble, each device can transport 1,600 liters of fuel per minute, and one tanker can install several sets, which can refuel several aircraft at the same time.However, when refueling is affected by airflow, the hose will fluctuate and the fuel delivery efficiency is low. It can only be used for fighter refueling.

Hard-tube refueling system. The refueling pipe is hard, stable, and easy to connect. It is suitable for air refueling of any type of aircraft, and the maximum refueling per minute can reach 6,500 liters.However, due to the complex technical structure, and only one oil receiver can be refueled at the same time, it is mainly used for large aerial refueling aircraft.

The hard-pipe refueling system is only controlled by the United States.

Under normal circumstances, the efficiency is the highest when the two fueling systems are used in combination on the fuel dispenser.

"Director Liu, we also know, but under the current circumstances, our technical foundation is weak..." Sun Daoqian said embarrassedly.

Why doesn't he know which way of refueling is more appropriate?

The problem is that the country has no technical reserves at all.

Even if there is an aerial tanker modified from the American Boeing-707, it is also because there is only one such machine, the processing technology and control technology cannot be reached, and we dare not completely dismantle the entire aerial refueling system...

With Chinese technology, once it is disassembled, it cannot be installed at all.

Even a lot of surveying and mapping work cannot be done because there is no suitable high-precision measuring equipment.

"At the moment, we still have time. Moreover, after flying for so many years, we don’t need to use H6 as the carrier. H6, it’s too small! If you use the American aerial refueling system After disassembling, drawing, and then reprocessing, how long will it take to produce successfully?" Liu Yijiu asked Sun Daoqian.

"We don’t have a three-coordinate measuring machine. We have negotiated with foreign countries several times, but they have not been provided to us and will not be exported at all. There are also some top five-axis machining centers, and the five-axis machining centers produced by the Ninth Institute cannot reach Precision..." Sun Daogan explained the difficulties currently encountered.

Liu Yijiu's brows suddenly frowned, "Do we already have a three-coordinate measuring machine in China? The five-axis CNC machining center of the Ninth Institute can't meet the accuracy requirements? Isn't this possible?"

"If it is machining, there is no problem. The key is a five-axis grinder. Many parts are processed with special-shaped curved surfaces..."

Five-axis CNC grinder, which is the top equipment of CNC machining center.

The Ninth Academy has just begun to conduct research in this area.

Some core parts of pressure equipment need to show that the finish is indeed very high, which requires superb processing technology.

Without equipment, the Ninth Institute can also produce it, but it will require more man-hours.

"Give the parts that require a five-axis grinder for finishing to the high-precision machining workshop of the Ninth Institute. In addition, the three-coordinate measuring machine is mobilized from the Ninth Institute. Is there any problem?" Liu Yijiu pondered for a while. , Aerial tanker, this is absolutely indispensable.

And there must be progress.

"This is no problem. If we can provide parts and a three-coordinate measuring instrument, we will be able to get it out in half a year!" Sun Daoqian looked excited, "I can make a military order!"

"I don't need you to make a military order, I only need to see the results. Moreover, I need to be able to refuel at least six fighters in the air at one time..." Thinking of the fact that only two fighters could be refueled at one time, Liu Yijiu Don't want it if it hurts."Install a hard tube refueling system at the tail of the tanker, and install a hose refueling system on the wings and belly. It is completely possible to refuel several fighter jets at the same time. In this way, as long as our aerial tanker has enough fuel, one can Provided to a squadron's fighters for aerial refueling..."

"This..." At the beginning, Sun Daoqian and others hadn't really thought about such a problem.

Even Hao Hongfei and the others were stunned.

It is impossible to imagine that Liu Yijiu would actually make such a request.

"At present, the development direction of fuel dispensers in various countries in the world is mainly to overcome the influence of wing vibration, gusts and air turbulence on the stability of the fuel pipeline; to convert into an aircraft with two types of fueling equipment; to improve the fly-by-wire fueling control system. These are also What you need to consider. Only by using a hybrid aerial refueling method can you be more flexible to adapt to various tasks."

"But this way, our project will be much more difficult!" Hao Hongfei finally found a chance to speak.

"How difficult can it be? Hasn't the hose refueling system been researched? There is also a hard pipe system, which will not take much time. Just integrate the two systems. Although I know it is more difficult to say than to do it. It's a lot simpler, but if we don't do it, can we solve the problem?" Liu Yijiu said uncomfortably.

For him, it doesn't matter how difficult it is, but whether the project team has such determination to do it.

If you are afraid of doing it, what can you achieve?

"Director Liu, this is not very appropriate. You have also said that we also need to deal with the effects of wing vibration, etc., to make the performance of the fuel pipeline more stable, and at the same time, we must improve the fly-by-wire refueling operating system, two operations on an aircraft. Does the system take up too much space and load? Even if the tanker can carry an extra ton of fuel, sometimes it has a very important role!" Zhao Yunhai frowned and asked Liu Yijiu.

The development trend of the world is said to be like this, but the US military has done it like this.

The Soviet Union did not consider this aspect. Their aerial tankers mainly used hose refueling systems, which did not have much influence.

After all, aerial tankers are mainly used for aerial refueling of fighter jets.

"The United States has long-range strategic bombers like b-52 and b-2, and the Soviet Union has super strategic bombers like Tu-95 and Tu-160, so their requirements for aerial tankers are not too high. Also, they have huge A large number of fighters are deployed throughout the country, and what about us? We only have the H-6, fighters, which have a combat radius of less than 3,000 kilometers. Apart from the J-10 and J-11, what is the combat radius of other fighters? Even ours The combat radius of the J-10 and J-11 is more than 1,200 kilometers, and can even reach 1,400 kilometers. How much can our country's national strength be equipped?" Liu Yijiu's words left Zhao Yunhai and others speechless.

The United States and the Soviet Union do not need too powerful aerial tankers, but they are still developing aerial tankers.

Regardless of Chinese fighter planes or bombers, the combat radius is really not enough to see, but there is no aerial tanker.

Logically speaking, China has higher and greater requirements for aerial tankers.

However, China's foundation is too poor, and it is not easy to build a larger, more powerful and advanced aerial tanker.

I haven't even gotten it done for so many years to transform the tanker from the H-6. Thinking about it now, it's obviously inappropriate.

"So, we must take into account the performance of our tanker, not just solve the problem of existence and non-existence." Liu Yijiu emphasized."It doesn't matter if you make a technologically advanced one, even if it takes a little time to hide."

"Director Liu, this needs more funds..."

Hao Hongfei reminded Liu Yijiu.

To do this, time is not important, what is important is that they need more funds.
