Chapter 689: Do they want to buy this plane?

The 107-fire and 130-fire both use turbo rocket engines.

This kind of rocket engine is one of the few solid engines in which one engine has many nozzles.

Because these nozzles need to be tilted at a certain angle to provide power for the rotation of the rocket, a single nozzle is undoubtedly not possible, and two nozzles are not suitable. These two rockets have 6 nozzles.

Although there are 6 nozzles, there is only one fixed hair.

"Although the turbine engine is easy to spin, there is a problem. Limited by processing technology, these six tubes cannot be completely balanced. At the same time, the distribution of the center of gravity of the rocket cannot be completely uniform. When the length of the missile is small, Fortunately, the longer the projectile is, the smaller the imbalance in the tail will make the projectile more unstable.”

"And in the later stages of flight, the burned-out rocket engine will cause the center of gravity to move forward, further aggravating the situation. And once the fuel is burned out, it can no longer provide rotational torque to achieve rotational stability, even if there is no problem with the missile body at this time, But the nutation of the long projectile will soon cause problems with the flight status of the projectile.”

As a simple example, rear-wheel drive vehicles tend to oversteer, which is actually a similar behavior.

The 130-fire rotation is powered by 6 nozzles at the tail. As long as these 6 nozzles are slightly unbalanced, this imbalance will be amplified on the long projectile.

In addition to the distribution and changes of the center of gravity of the projectile, the rocket with a turbo rocket engine cannot, firstly, have an aspect ratio that is too large, and secondly, it cannot hit too far.

The comrades in Fenglei Factory said nothing, just rolled up their sleeves and just took notes!

These things that Chief Engineer Gao said are all theories and are not aimed at 130 fire at all. This means that what I heard today can be used with 130 fire and 180 fire. Even if I want to make new bombs in the future, it can still be used.

Although it has not solved what ammunition should be used, at least what should not be used is clearly explained theoretically.

The comrades of the Fenglei Factory were working hard to acquire knowledge, while the comrades of the Defense Work Committee looked at the sky and saw that it was already very late.

Since there was a lot of estimation, reasoning, and calculation of actual equipment during the discussion, it took a long time, and the comrades of the National Defense Work Committee had other considerations.

He said to other comrades: "Comrades, it's getting late today. Should we stop here first? Come back to General Engineer Gao for advice another day?"

The comrades at Fenglei Factory were a little stunned. Is it too late to do work these days?

Gao Zhendong didn't take it seriously: "It doesn't matter, I have time, it won't be a problem if we talk for a while. Comrades come here once in a while, so we can't waste time by letting them run around half-assed."

The comrades on the National Defense Working Committee had somewhat different ideas.

"It's not just for this reason, Chief Engineer Gao. I noticed that many of what you have been talking about are theoretical issues in rocket launcher design research, or very important basic technologies. I am wondering whether it is necessary to develop large-caliber rocket launchers. Comrades from the Rockets also called over to listen together.”

Comrades from the Land Loading Bureau also thought about it: "Well, yes, yes, I think it's reliable. It doesn't matter that the 107 has a short range, but the 180... well, the range is also close, but the 180 is a planned large-caliber rocket launcher. It is necessary to come and learn from it. It is not a good thing to be so close all the time. It is not a good thing to ask Mr. Gao to speak twice. It would be a waste of time.”

To be honest, when the comrades of the Land Loading Bureau think of the current range indicator of the 180, they feel that something is wrong everywhere.

Apart from anything else, the 130 has at least 15 kilometers now, right?

180 for 10 kilometers? What a fuss!

The comrades of Fenglei Factory were in high spirits, so they didn't want to end it like this: "It's okay for us to listen to what Chief Engineer Gao has said and then paraphrase it. Chief Engineer Gao's words were explained in simple terms and easy to understand and paraphrase, and the details should not be lost." .”

The comrade of the National Defense Working Committee smiled and said: "It is better to listen to them in person. Their problems may not be the same as yours. If you listen to them in person, you can also ask some questions that can be solved in person."

It's impossible to solve all problems, but at least in the area that Gao Zhendong is good at, he can ask questions face to face.

Comrades from the Land Decoration Bureau also think this is true.

"Yes, yes, it is better to invite the comrades who are involved in 180 to come and listen to this matter in person."

Both the National Defense Working Committee and the Land Loading Bureau insisted that the comrades in Fenglei Factory should no longer be stubborn. They couldn't just enjoy themselves and leave other comrades with similar difficulties aside, right?

Seeing that they had reached an agreement, Gao Zhendong did not insist. This was good, as he would waste less time and settle the matter.

Gao Zhendong made an appointment with them. The next day was impossible. It was very difficult for the comrades involved in the 180 Fire to reach the capital in one night.

Amid the excitement of the National Defense Work Committee and the Land Loading Bureau, as well as a little bit of regret and expectation from Fenglei Factory, they bid farewell to Gao Zhendong.

At about the same time, Lao Maozi's house.

Linochka approached the minister with a document and a strange look on his face.

"Comrade Minister, our comrades from the south have made a strange purchase request to us."

"Really? How strange is my Davari?" For the minister, Linochka, who has become increasingly mature, feels strange, and that is indeed worthy of careful questioning.

Linochka placed a document in front of him.

"They are asking us to buy the discontinued Be-6 seaplane."

The Bie-6 is a water patrol aircraft designed and produced after Laomaozi S2. It was put into production in 1949 and discontinued in 1955.

We imported 6 aircraft in 1955, which were said to be our most expensive aircraft at that time. How expensive was it? One piece of this thing can buy 15 MiG-15s...

But although it is expensive, the stuff is still good.

A range of about 5,000 kilometers, a flight time of 16 hours, and a maximum external load of 4 tons for 4 pylons.

In terms of hard indicators, many are even better than its successor, the Be-12, especially in terms of range and bomb load.

The most amazing thing is that when a B-6 was participating in a competition, it exploded and sank into the water due to a depth bomb malfunction. No one was killed, and only one person was injured. What's even more amazing is that the aircraft was fished out a few days later. Come on, we've fixed it...

Of course, this product is not without problems. The biggest problem is the landing gear. The landing gear of this product needs to be assembled and disassembled in the water. But considering the range and bomb load, I guess we can bear it.

With a hint of curiosity, Comrade Minister picked up the document and looked at it carefully: "They want 18? Vladimir, why don't they ask to buy back our production line?"

There are many opinions on the specific production quantity of Be-6, but the relatively unified one is that it is only between 120 and 150. In other words, our request, plus the original purchase, is equivalent to buying the Be-6 directly. One fifth of the total!

Hearing Comrade Minister's complaints, Linochka shrugged: "Comrade Minister, you guessed it so accurately. That's what they asked for from the beginning. After we rejected it, they turned to ask for 18 aircraft."


Comrade Minister was stunned for a moment. He didn't expect that the appetite of the southern comrades was so big!

He looked at the document carefully again and raised his head: "Linochka, what do you think of this problem?"

Linochka shook his head firmly: "I don't recommend selling them. 6 are enough for them. Adding 18 more will pose a serious threat to our submarines in the Pacific."
< br>

The existing six Be-6s are deployed in Jade Bird City in northern my country. Interestingly, the secret code name of the Be-6 in the 1960s happened to be "Blue Bird".

Lao Maozi is very clear about the deployment location of Bie-6. The reason is very simple - this base was helped by others to survey, select the site, and expand it. The site selection options at that time even included Dongyue Province. Cape City.

Yes, at that time, Haijiao City and Tianya Island, where it was located, belonged to Dongyue Province.

Originally, the base in Jade Bird City was a seaplane airport in the early years of Hans Cat. After several twists and turns, it finally became our seaplane base.

The Bie-6 is deployed in the north and will undoubtedly pose a certain threat to the submarines of Laomaozi's Pacific Fleet.

Comrade Minister shook his head: "I don't think so. I think that they are buying these aircraft not to continue to deploy them in the north. Instead, they are more likely to be deployed in the south."

Linochka was a little puzzled: "Comrade Minister, they only have one base in the north that can deploy seaplanes."

The minister smiled: "Comrade Linochka, you can't underestimate our southern allies. They have enough technology and capabilities to build seaplane bases elsewhere. And for their northern seas, 6 Jiabei-6 is already saturated.”

In the opinion of Comrade Minister, in the northern waters of the ally, apart from patrolling and guarding the other party's ridiculously shallow inland sea - Bohai, seaplanes are of little significance, and 6 are enough.

"Moreover, the Be-6's submarine detection system has seriously fallen behind. The Pacific region has never been the focus of our navy, and their northern waters are not the main scope of our submarine activities. Therefore, the threat of the Be-6 to our submarines is not Big.”

Lao Maozi's strategic focus is in the west. Whether it is land or sea, the Pacific direction is not the focus. However, in the west, their navy's combat environment is extremely poor. It is either ice and snow, or the exit is strangled by others.

This is also a very real problem for Lao Maozi's navy: the sea area is not large, and the transportation and geological environment are extremely poor, resulting in no synergy in naval construction.

And from the perspective of strategic focus, terrain distribution, geopolitics, international relations, economic and trade routes, etc., apart from covering the big black fish and driving the big bombs out, they actually have no very urgent maritime needs.

To a certain extent, Lao Maozi’s naval construction strategy, which seems strange to outsiders, is not completely unreasonable.

Linochka was very puzzled: "Then why do they import so many B-6s?"
