Siheyuan: Supernatural from the Ninth-level Engineer

Hongqi-9 air defense missile system, the missile range of the basic model reaches 125 kilometers.

The improved version has a range of at least 200 kilometers.

Even the basic model data, the system did not give him.

Strength doesn't allow it.

The Hongqi-9 air defense missile only needs an active phased array fire control radar to complete the search and reach 400 kilometers.

All functions such as early warning, ranging, altimetry, guidance, etc., the detection distance is even more

This is only the distance of the air defense system.

If connected to the domestic radar network, the target can be detected thousands of kilometers away.

"It's not about tracking. The missile's performance is too advanced, and the equipment can't keep up, which will make the missile's performance unable to play out."

Another expert said.

"Can you lower the range, etc.?"

Director Tang also spoke.

Reduce the range, it will definitely save costs.

too expensive.

If it is also fired in the same way as the Hongqi-1, three at a time.

Air defense forces really can't use it.

"No. The v-2 missile used by Maoxiong's sa-750 system is divided into two cores, using fuming nitric acid-kerosene as liquid fuel..."

Yang Gang spoke very professionally.

Let the experts keep nodding.

They all do this work.

As soon as I heard it, I knew whether Yang Gang was really familiar or just to fool people.

"Solid fuels are much more expensive than liquid fuels..."

Director Tang doesn't want to focus on performance issues now.

cost!

The first stage is a solid fuel booster, which is to allow the missile to gain initial velocity with speed.And the second level

Too expensive to use.

"Using cellulose nitrate and glycerol trinitrate as dual-base fuel, and adding other additives

What Yang Gang said made Director Tang look bewildered.

Can't understand it at all!

Solid fuel propellant, but something that has not been researched in China.

Liquid fuels are cheap.

Disadvantages are also obvious.

Save time is too short, long-range ICBMs, pre-launch preparations take too long...

"This……"

Even the experts don't know the truth.

Seeing that Yang Gang was right.

They don't know.

Usually engaged in missiles, are in contact with liquid fuel.

"It's not really expensive. Cellulose nitrate, obtained from the nitration of cotton or wood fibers, serves as a matrix; nitroglycerin (glycerol trinitrate) dissolves it, shapes it, and forms a colloid...I was in school before When tested, the combustion efficiency is much higher than that of liquid fuels..."

What's going on here?

People do it all at school.

A group of experts found that only President Qian could understand what Yang Gang said.

Look at their expressions.

Chief Yang spread his hands helplessly.

Shrug.

The strength does not allow him to design more garbage missiles, and he is also desperate.

"Actually, whether it can reach the theoretical design, or if there are any problems, we can completely produce a few sample bombs first, shoot them out, and know what Yang Gang proposed.

261 lack of target machine?Use Eagle Sauce's fire bee and u-2 over the small pond to the south as a target drone.

"Manufacture? Control computer chips, ours can't meet this requirement..."

An expert said immediately.

"I have."

Yang Gang laughed.

Everyone's eyes widened.

He looked at Yang Gang in disbelief.

Yang Gang has it?

If there is such a thing, the performance of all missiles in the country will be greatly improved.

Especially ICBMs.

Director Tang looked surprised, "I got it~?"

"Although the size is still larger, the performance still can't reach the design target, it is enough for this, Yang Gang said.

"How about we go to the factory?"

"Mr. Yang hasn't eaten yet..."

Ding Qiunan was blocked by Feng Lei.

With rice in his hands, his face was covered with frost.

Seeing a group of people come out and say that they are going to the factory, they are immediately anxious.

No matter how busy you are, you can't make people hungry, right?

I haven't eaten well for several days.

A group of experts and Director Tang immediately became embarrassed.

"Put your stomach first. Let's go to the factory in a while and let your factory cafeteria fill a table for everyone to drink in the evening."

Director Tang reacted.

Yang Gang was not polite, and let a few people go to the factory first.

Go after eating by yourself.

"You really don't take your body seriously!"

Ding Qiunan sat opposite Yang Gang, resting his chin on his hand, watching him gobble.

When Yang Gang put down the bowl, he was ready to serve the rice again.

Yang Gang said that he didn't want to eat and had to go to the factory.

Immediately complained.

"You haven't eaten properly for a long time, you can't eat too much, or your body won't be able to take it. You studied medicine, don't you understand?"

Ding Qiunan just remembered.

Yang Gang's medical skills are much higher than his own.

"That's it?"

A piece of slap-sized, thick fingers, and a black thing appeared in front of everyone.

"Yes, this is the 68000 chip designed by President Yang, which can process 300 million data per second..."

Zhu Mingguang and Zhao Bingyi introduced the specific performance of the chip in their hands to everyone.

"So, let's make a sample directly."

Yang Gang said.

There was excitement on the faces of the other experts.

Director Tang's mouth twitched.

Expensive!

"How much does it cost to make this sample?"

Solid fuel propellant.

Infrared homing active guidance.

New engine.

Director Tang pondered that if it wasn't for Yang Gang to save costs, vertical launch could be used.

"This is not expensive. The sample trial production is estimated to cost about XNUMX yuan. When the technology is mature and the cost is reduced, the price should be controlled within XNUMX yuan." Yang Gang said.

Solid fuel, other air-to-air missiles, air defense missiles, surface-to-air missiles, intercontinental ballistic missiles, anti-ship missiles, can be used.

The larger the production scale, the lower the cost.

Nitrocellulose and nitroglycerin are not expensive.

As for guidance systems, engines, chips, etc.

more widely used.
