The butcher did not answer Lin Zheng's question, but asked Lin Zheng with a smile: "Mr. Lin, you are also a person in our military industrial system, and you are ...... about ejection seats. Well, how much do you know about the parachutes used on the fighters of our national air force? ”

Lin Zheng really doesn't know much about this thing, just imagine, as a military fan, in most cases you will only be interested in the performance of weapons, great you may know more about the weapons carried on the plane, maybe you will know the performance and data of a certain fighter jet well, but who cares about the ejection seat. Pen ~ fun ~ pavilion www.biquge.info reading artifact

Lin Zheng is a relatively senior military fan, and he has an incomparable advantage over ordinary military fans, and after a deep sigh, Lin Zheng said: "It seems to be a square parachute, the kind that can glide and adjust the direction at a certain distance?" ”

Theoretically, the non-powered parawing can also glide for a short distance, basically can ensure a gliding ratio of more than 15:1, that is, every 1 meter drop in height, the parachute can glide forward more than 15 meters, with a pilot parachuting after the height of 500 meters to calculate, when he landed, he has drifted out of 7500 meters from the coordinates of the parachute, which is basically enough to ensure that the pilot avoids the more dangerous area on the ground.

Of course, this is only the ideal scenario, and in practice this distance may be longer or shorter due to the influence of rising and descending airflows.

"That's right, that's it."

"......" Lin Zheng looked at the butcher, hoping that he would continue to speak.

"We have analyzed more than 200 actual cases of fighter pilots parachuting to survive at home and abroad from the early 80s to the present, and have come to a surprising conclusion: in the vast majority of cases, after the pilots parachuted, the terrain where they landed was very bad, and it was very inconvenient for the rescuers to carry out the rescue."

After seriously thinking about a few cases of pilots who he knew of parachuting to survive, Lin Zheng had to nod: "It seems ...... That's true. ”

"But after an analysis of the strip where these pilots landed. We found another interesting situation, even if the pilot was able to fly another 50 kilometers in the center of the circle where he landed after the parachute jump, it would make our rescue work much easier......"

"I understand," Hearing the butcher say this, where did Lin Zheng still not understand what he meant? It suddenly dawned on me: "What do you mean is that if the fighter pilot's parachute is converted from an unpowered parachute to a powered parachute, not only will the pilot's chances of escape be greatly increased. It's also much less difficult to rescue, right? ”

The pilot initiates the ejection seat escape is divided into three processes, the first process is to pull the ejection pull ring of the ejection seat to start the ejection program; In the second step, after the ejection is successful, the parachute is opened at a suitable time according to the actual situation to separate the person and the chair; The third step is to land.

The butcher thinks about the third most important step: landing.

The overall weight of the parafoil and the pilot does not exceed 100 kilograms, in fact it is generally less than 85 kilograms, calculated by the huge wing area of the parafoil. You don't need to think about altitude climb as you would if you were taking off on the ground. It is only necessary to ensure that the lift-to-drag ratio of 0.15, that is, 12.75 kg of thrust is enough to ensure that the pilot is flying in the air, to provide more than 13 kg of thrust, a kilometer of about 2kw of electric motor can be satisfied, a battery with a capacity of 1kw.h is enough to ensure that the pilot is in the air for more than 30 minutes, with a reasonable gliding and operation mode, it is enough to ensure that the pilot flies out of more than 50 kilometers - the distance of 50 kilometers, It is enough to ensure that the pilot's chances of survival are many, many times higher.

Lin Zheng understood what the butcher meant: "So the weight of the battery has become a key consideration?" ”

"Yes, we have also considered using lithium batteries, but regardless of the cost, a 1 kWh lithium battery weighs almost 7 kilograms. Considering the volume, it's really hard to place, so ......"

So after seeing this flywheel battery exhibited by Lianchuang Technology. The butcher immediately realized that the problem of choosing the right landing place for the pilot after parachuting was solved: a flywheel battery the size of an ordinary red brick and weighing about 2 kilograms could provide about 2 kilowatt-hours of electricity, which was really tempting.

Even for HNA pilots. Flying in the air for more than an hour is enough for the base to send a rescue team...... The ejection rescue seats of the Hainan Airlines are different from those of the Air Force. Considering that many times it may need to be ejected at sea, people are not only equipped with life-saving inflatable boats, but also have more food and water to save lives than air force pilots.

"It is our honor to do what we can for our army building." After figuring out what was going on, Lin Zheng immediately said without hesitation: "But it may be ...... in terms of cost."

The butcher interrupted Lin Zheng's words and asked with a smile: "Mr. Lin, do you think we will put cost first?" ”

Stunned for a moment, Lin Zheng also smiled: Indeed, as a military equipment, it is definitely not possible to consider the cost factor, but in the same way, for a military equipment, it is definitely not the cost factor that is considered in the first place, don't look at the ejection life-saving seat is a chair, but at present, the cost of the ejection life-saving seat in the world is generally between 200,000 US dollars and 300,000 US dollars, and the self-weight is also about 500 kilograms.

Compared with the cost of two or three hundred thousand dollars, the cost of the extra battery and electric motor is really nothing, how much does it cost and how long does it take for the country to train a fighter pilot? How much is a 2 kWh flywheel battery? Even if this battery only plays a role once in a lifetime, how much money can it save the country?

If you really want to be careful about this kind of detail, then simply cancel the army: the country needs so much money every year to feed the army, and it doesn't fight anyway, so why spend that money?

"We can only produce some batteries in small batches in the laboratory now, and there are at least five or six years before small-scale industrial production," Lin Zheng asked tentatively: "Will this delay the progress of the project on our side?" ”

"No," the butcher waved his hand: "You can provide us with a batch of batteries for experiments first, our project will take some time, then again, even if you haven't been able to achieve industrial production by then, it doesn't matter, this little production capacity of your laboratory is enough for us." ”

This is also true, Lin Zheng didn't react for a while just now, but now he reacted: The Republic is also an air force, starting from the J-7, even if you count the H-6 bombers, how many planes are there in our country?

In order to ensure that the combat effectiveness is not affected, the number of ejection seats that need to be updated every year is gradual, and the production capacity of Lianchuang Technology's flywheel battery is not high, but even the production capacity in the laboratory state can basically meet the needs of the military.

Thinking about it, Lin Zheng suddenly smiled: Big business is coming to the door! "Please rest assured that we will provide us with high-quality battery ...... with quality and quantity."

Speaking of this, Lin Zheng's brain suddenly opened: the ejection rescue seat of the fighter needs a flywheel battery with high energy density, so do the special forces performing special operations and the paratroopers performing airborne operations also need this thing? Imagine that our fighters who carry out airborne operations and special operations are quietly approaching the enemy from the air at a distance of hundreds of kilometers......

It's not too pretty!

"Why didn't I think of that?" After listening to Lin Zheng, the butcher's eyes also lit up: if he could take down this business, the life of the 610 Institute would be better: a power parachute with auxiliary power. "Well, Xiaolin, your suggestion is good, in this way, I will make a report when I go back."

………………………………

After sending off the butcher, Lin Zheng immediately called the pony over: "How long will it take for our flywheel battery to reach mass production?" ”

"At least 3 years." I don't know why the boss is so concerned about this issue all of a sudden, but that's not the point, the point is that the boss cares, and the pony immediately said cautiously.

"Slow!" Lin Zheng's brows immediately furrowed: "2 years!" It will take two years at most, and I will have to build the production line. ”

"2 years? Boss, it's simply impossible! Xiaoma's face suddenly wrinkled into a bitter melon: "Boss, there are still many technical problems and process problems that need to be solved, 3 years is already the most optimistic estimate, if there are any problems that are difficult to solve in the process of transformation to production, maybe four or five years may not be able to put into production." ”

"I don't care about this, I only need to put the flywheel battery into production within 2 years," Lin Zheng was unmoved in the face of Xiaoma's complaints: "Tell everyone that no matter how much money is needed, the company will meet them, but 2 years is a line, and it must be done." ”

"That'...... Okay, I'll convey your meaning right away," the boss insisted so much, the pony didn't have a move, hesitated, and the pony asked carefully: "Boss, we don't need to be in such a hurry......"

"The military may order flywheel batteries in large quantities in the future, and we must prepare early now." Lin Zheng whispered.

"Huh? Military? Stunned for a moment, the pony suddenly covered his mouth tightly, lest he call out: no wonder the boss suddenly became so anxious, it turned out that the military was very anxious, this is understandable, at any time, military products are the guarantee of profits, not to mention that only their own company in the world can mass produce flywheel batteries?

The pony immediately said impatiently, "I'll go!" (To be continued.) )
