Chapter 204: Advanced equipment is the key

"Grandpa, please see..."

Song Yingxing pointed to the newly-made grenade on the table: "According to the grandfather's idea, Xiaguan and many craftsmen in Taixi developed it together, improved it on the basis of our old-fashioned sky-shaking thunder, and developed this new type of sky-shaking thunder, which is packed with fifty small round steel balls, and the killing range can reach ten steps after exploding...

In addition, due to the instability of the new gunpowder, the current method of use is to ignite the old-fashioned medicine line, which can explode within five breaths after ignition. ”

"Named 'grenade bullet', it can also be called a grenade," Chen Cao picked up a grenade and looked at it: "The white phosphorus that I told you last time, did you succeed?" ”

"It's done," Song Yingxing nodded: "This thing can be used as a burning substance, but if it ignites this thing, the danger is too great." ”

"When you design a new type of grenade, you need to design it in a way that doesn't require ignition, and in addition, I talked about it once when I was at the academy last time, and this kind of grenade and bullet was temporarily discontinued after it was produced, so people can devote themselves to designing a rope grenade."

After being told a few times by Chen Cao, Song Yingxing was very ashamed, so he handed over his hand and said that he would definitely handle this matter well.

"How's the rifle thing going?"

Chen Cao took a turn in the workshop, then turned his head to look at Song Yingxing who was following behind, Song Yingxing hurriedly pulled over Bi Maokang, who was even more powerful in firearms research: "Grandpa, the completion is nearing the end, but there is still a gap in bullets." ”

Bi Maokang also replied: "The original rifle after firing ten bullets, the bolt bolt will burst due to insufficient friction and overheating inside the barrel, so the forging of the barrel has been the same as the forging method of the Taixi people, and other minerals were added to the molten steel to form the alloy that the grandfather said, and the effect was really good, after the thirty rounds of bullets were fired, although the rifle barrel was heated, it still did not affect the shooting." ”

"But grandpa, bullets are a big problem." Song Yingxing was a little embarrassed: "The successful construction of the machine tool allows us to make bullets as we like, but the current productivity of the compression drilling machine is not large enough, and under the premise that the copper material is not enough, in addition to the test gun, the workshop does not dare to produce excess bullets." ”

Copper rifle warheads are really expensive, and although the workshop has sufficient funds, most of the energy is now devoted to the development of new artillery.

"Copper is a scarce mineral, and we don't have too many copper mines in the Ming Dynasty, grandpa, you see?"

Bi Maokang said a little tactfully, but Chen Cao waved his hand: "You don't have to worry about the raw materials of the bullets, even if you build it, according to the calculation method of the Taixi people, the bullet head should be made into a 7.62 mm rifle bullet, and the vernier caliper on the drilling machine should be based on the Taixi number, if you can't get it right, let them get it;

Also, from now on, you will make as many bullets as I can get you copper, and you must make me as many bullets as you want, and the bullets for combat readiness cannot be less than one million. ”

"A million?" Bi Maokang shook his head again and again: "Impossible, grandpa, although we can make bullets, but the production proficiency is not high, even if we don't count the time for melting copper to finalize, the production of a bullet from the gunpowder machine tool to the drilling machine, it is not possible without half an hour." ”

"Half an hour is too long," Chen Cao shook his head again and again, the production of bullets is clear to him, later generations are mechanical automation, and now manual manufacturing, but the time is not enough: "The more drilling machines and machine tools, the better, the same as water hammer, designed to be hydraulically driven, the time can be reduced a lot, in addition, you can't forget the matter of brushing tung oil, otherwise the bullet will be bad..."

"I'll do as I was told..."

After Chen Cao finished arranging it in one go, he took over the left revolver gun that he had personally drawn and designed from Song Yingxing, the bright white gun body design was made of one of the few alloy stainless steel in their workshop, and it weighed a pound and three taels: "Well, this is good, is it customized?" ”

"This is the grandfather's first hand..."Bi Maokang said with a smile.

"This **** is named 'Daming 1626 type left revolver gun', and after the new pistol design is available, this gun can be exported." Chen Cao played with it, and then loaded six bullets.

Bang...

After a puff of smoke, the target in the distance was shot, Chen Cao nodded with satisfaction, and then inserted the gun into the special holster, and put the gun suit into the waist of the clothes.

"The rifle, it's called the Daming 1624 bolt-action rifle, it will be produced quickly after it is ordered, it can't be delayed, and it will be wrapped after the production is done, and it will not be delayed when it is used in the future."

After Chen Cao finished his instructions, he took his family and bodyguards to the Nanjing Military Academy not far from the workshop, and he wanted to go to the academy to see their research results.

As soon as he stepped into the academy, Chen Cao heard a burst of cheers, followed by the sound of a machine turning.

Today's Cao Shiyun is a fifteen-year-old boy, he stands in front of the steam turbine he has worked hard to develop in the past three years, and then keeps instructing his classmates in the R&D team to operate this rather large machine.

It wasn't until Chen Cao stood behind a group of students that Cao Shiyun, who was standing on the high platform and was personally shoveling coal for the boiler of the steam engine, saw Chen Cao wearing a duke's python robe.

In addition to the excitement, Cao Shiyun ran off the high platform and hugged his fist towards Chen Cao: "Grandpa, live up to the teaching, the student has successfully developed a steam turbine." ”

The circle of gears with a diameter of one meter on the right side of the turbine is driving the crossbar below it, and the round rotation of the crossbar makes the gear of the crossbar tell the rotation, and the gear lever connected to the pinion drives two suspended wooden wheels, and the wheel rotates rapidly.

"Well, yes, and I know that in the experimental phase, the wheels are suspended in the air, and if you use wooden wheels, the weight of the wheel is enough to bury the wheel in the ground."

Chen Cao nodded with satisfaction.

Cao Shiyun's face was covered with black soot, and so were his classmates, the steam engine was the first major project requested by Chen Cao, so the academy allocated a lot of silver in the entire class, and the composition of this engine was made by these students in the workshop under the personal watch of those craftsmen.

"The students discovered this, this turbine weighs 3,000 catties, according to Taixi's calculation, it weighs six tons, if you only use the kind of technology that our Ming Dynasty built a carriage, the two load-bearing wheels should be at least about three tons."

"You are ruthless and smart," Chen Cao touched Cao Shiyun's head: "But have you thought about it, two wheels weigh three tons, are there any other alternatives?" ”

"Yes," Cao Shiyun nodded confidently: "The student thought of lengthening the front of the car, and placing six sets of wheels on the front of the car, so that the weight can be balanced and it can be safer in terms of traction." ”

At this moment, there was a sudden loud bang in the engine, and it turned out that the boiler had exploded.

"Blew up again..."

Cao Shiyun turned his head to look at the turbine behind him, and then looked at Chen Cao very embarrassed: "Grandpa, although the students thought of this, after the success of the past year, they blew up no less than ten boilers, and the students really can't think of how to solve it." ”

Chen Cao stepped forward to look at the coal destroyed by the hot water spewing from the blown up boiler, and then looked around again, and he found that this turbine was missing one of the most important things.

"Cao Shiyun, my father asked you, what does this turbine rely on to rotate?"

"Steam...," Cao Shiyun replied immediately.

"You think, your internal rotating turbine is only so big, in this enclosed space, steam is constantly generated, and the turbine can only use so much steam, so what to do with all this excess steam?"

This is an academic question, Cao Shiyun immediately began to think about it, and then said: "The excess should be let go... But grandpa, there is not enough steam in the engine after it is released, and once it is released, the engine will stop rotating. ”

"You should have thought about this question a long time ago..."

Chen Cao looked at a pull rope next to the boiler with interest: "So you made this pull rope." ”

"Yes," Cao Shiyun nodded: "It's just that it's not used once, every time three catties of charcoal are burned, the student will pull down the pull rope, open the lid of the boiler, release the steam, and then the turbine will stop." ”

Chen Cao laughed and said, "Why don't you make a pressure gauge?" When the steam reaches a certain critical value, pull down the rope and let go of the steam, isn't that the best of both worlds? ”

Cao Shiyun's eyes lit up, this smart student had already thought of something, but then he dropped it again: "But pull down the rope, and the steam will be exhausted." ”

"Idiot," Chen Cao scolded: "You install the spring made by the firearms department on the boiler cover, you pull it and put some steam out, and the lid will be restored as soon as you loosen the power of the spring, you just need to put as much as you want?" With the help of the pressure gauge, as long as it doesn't reach the critical value, you can toss as much as you want..."

"That's right..."Cao Shiyun patted his head: "The student has to be taught by his grandfather, and he already knows how to do it." ”

"It seems that Mr. Taixi's teaching you is not talking nonsense, you have learned quite well, come here, Cao Shiyun and his research team have made meritorious contributions to the research and development of steam turbines, and each of them will be given a scholarship of 1,000 taels, and another 50,000 taels of silver will be allocated to them as funds for the improvement and development of turbines."

"Grandpa Xie..."

According to the etiquette of the college, the students raised their hands and raised their eyebrows to Chen Cao to express their gratitude, and Chen Cao returned the salute and went to the firearms department of the college.

Lin Liangcai is now the leader of the firearms department, and he first proposed the alloy cold forging technique after being taught by Mr. Taixi.

"The student has seen Grandpa..."

The news of Chen Cao's presence in the steam department has already been told to them by the teacher, so Lin Liangcai can't wait to show what he has developed in the past three years.

"In fact, we are only limited to the manufacturing technology of the machine, if we increase investment in the industry, I believe that the forging technology is more advanced than the Taixi people..."Chen Cao said noncommittally.
