Five-axis linkage CNC machine tools are definitely the best production tools for complex curved products, especially propellers. In the 1980s, when China was in the honeymoon period with the West, China introduced several units from the West and domestically developed five-axis linkage CNC machine tools.
, started on this basis.
Although these imported machine tools cannot yet produce large propellers for submarines with a displacement of several thousand tons, they can still produce water jet propellers for missile speedboats with a displacement of several hundred tons.
"I heard that these CNC machine tools require programming to be used. So far, we can only use the programs that come with imported machines to produce established products. We are still studying those programs domestically, and no one can write programs for brand-new products."
There were still knowledgeable people on site. After all, the propellers processed by that thing could greatly reduce the underwater noise of submarines. They rushed to ask for advice excitedly, but the result? No one could write programs, and they had not yet fully understood the principles of the machine.
.
"I understand." Qin Tao said, "I can write relevant programs."
"You understand?"
"Either spend precious foreign exchange and import from abroad, or try it yourself. The choice is yours."
"Okay, let's give it a try! We are responsible for coordination." The leader on the scene made the decision: "Although there are still many details, but now, given that this design is very excellent, I personally agree to hand over our passenger ship order to
Mingzhou Shipyard will no longer consider other design offices and shipyards."
As Qin Tao guessed, mosquitoes are still meat no matter how small they are. Many people are watching them. Although Qin Tao has made great contributions, there are also people who shamelessly come to ask for the missile boat contract. What they say is hard to hear.
How can that shipyard that almost went bankrupt take on the task of building passenger ships or even warships, even though it only builds fishing boats?
The top brass of the Navy were also shaken, but now, looking at Qin Tao's design, they were completely convinced. The first task of building a passenger ship was handed over to the Mingzhou Shipyard.
"Other design institutes and shipyards?" Qin Tao caught this sentence, and then looked at Pang Jianmin and Zhang Zhen: "You two, what you promised once almost didn't count?"
The expressions on both of their faces were very embarrassing. They were soft-spoken and soft-handed. They took four torpedoes and agreed to the construction contract of a small surface wave-piercing catamaran. In the end, they almost turned it down. They were really embarrassed.
"Of course not." The leader came to the rescue in time: "We were originally leaning towards Mingzhou Shipyard. Now, with your advanced design, we have nothing to say. There is a design institute in the south, and we also want to undertake it.
However, they can't do this task well on their own and have to cooperate with Australians. But in this way, the price will go up. Your design scheme is advanced and based on China, so the price can also be lowered.
We are satisfied. The superiors have allocated two million for this project. You..."
"We charge 1.9 million, and the remaining 100,000 will be kept in the headquarters as your office expenses." Qin Tao was very polite. It was normal to give kickbacks for projects. In the 1980s and 1990s
The army is very miserable. Faced with the pitiful military expenditures, the leaders of each army have a headache. Then, the Eight Immortals cross the sea and show their magical powers. Some troops eat meat and some eat wild vegetables.
"Okay." This kind of thing can be said directly, and no one is embarrassed. The leader immediately agreed: "However, if the design indicators cannot be met..."
"We will compensate the troops two million." Qin Tao said simply.
"In order to cover up the public's eyes, we need to set up a special passenger ship company to prevent the outside world from seeing that this is a military project." The leader said: "If there is no problem, we will sign the contract now."
Qin Baoshan, who had been sitting there watching the excitement, now had his turn to play.
In the early 1980s, the domestic shipbuilding industry was in dire straits. In order to develop, the country decided to go abroad and undertake shipbuilding for customers from various countries. When negotiations began, it was discovered that there were quite a lot of details in the contract, even the direction of the cables and the design of the gangway.
There are special specifications. The thick international standard contract seems extremely cumbersome.
It's different in China. Signing a shipbuilding contract is just one page. The basic data is listed and how to build it. It's the shipyard's business. Even the acceptance is the responsibility of the shipyard itself, unless it's a warship.
Only then will military representatives be responsible.
"It's getting late, Captain Zhang and Political Commissar Pang, since they were invited by you, take them to have something to eat." The leader said with a smile.
This is also to save office expenses.
"We should invite you." Qin Tao replied.
"Let's invite you. Just go to the small canteen in our headquarters and cook a few dishes." Zhang Zhen said, "It's also for what happened last time. Thank you."
The canteen is on the other side of the headquarters, so to get to the canteen, you have to walk along a long pier road.
Qin Tao didn't care. He was extremely excited as he walked and watched. The warships on the dock were a feast for his eyes.
Aged destroyers, frigates... Suddenly, a warship caught his eye: "Our No. 531 is back? This is a meritorious ship!"
The 531 warship is a type 053K frigate with a displacement of less than two thousand tons and a low cost. It is the backbone of the navy.
"Yes, he came back after the naval battle last year. He has completed all the test projects and is the main force of our air defense." Zhang Zhen said.
This warship was designed as an air defense frigate. It was planned to be equipped with Hongqi-61 air defense missiles. Unfortunately, this missile has been in trouble and various problems have emerged. The 531 warship participated in the battle last year.
At that time, this missile was not equipped, and it was not until the end of the naval battle that it came back to continue testing.
At the front of the bow is a twin-mounted 100mm naval gun. On the second deck behind the gun, there is a twin-mounted swing-arm missile launcher. However, it is empty and no missiles are seen.
