Li Zhen said, let him try.
Then you must try it.
According to Liu Jinghong's idea, they have to wait until the mobile hospital has achieved a breakthrough and all the data has passed, and then they can conduct experiments when they are fully theoretically prepared.
But Li Zhen didn't want them to waste time like this anymore.
Instead of pinning all your hopes on others, it is better to hit the wall once and then keep your feet on the ground.
After Li Zhen's words, the people from the Automobile Research Institute fully cooperated and temporarily shelved the plan to develop a rotary engine. Turn to test data for the radial engine.
Once I tried it seriously, I realized that it was too difficult.
Because it is difficult to make two engines produce the same power. Every engine is absolutely unique and has its own faults.
The problem is obvious.
Because the industry of New Kyushu cannot be compared with the industry of Zhang Zhi's time.
Although New Kyushu is an industry, machines only replace human power, but humans are still needed to direct it.
If you are cutting a steel plate, you need to measure the size manually and then cut it manually with a machine.
If the data is measured by humans, it will never be absolutely accurate, and there will definitely be various small errors. Even the most professional master craftsman will have his hands shake sometimes.
In Zhang Zhi's time, it was a real CNC machine tool.
The computer directly commands the machine to cut. The computer has an advantage over the human brain in that it will not make mistakes in data. If we say that this batch of goods all have the same specification, then they are absolutely all of the same specification, and there is absolutely no possibility of errors. Not even a millimeter.
But New Kyushu's industry is far from that level. Even if there are templates to constrain it, it still cannot be perfectly accurate.
Small differences in component specifications will lead to power errors in the finished engine. It is almost impossible to build two engines with the same power and power.
This is what Li Zhen said, why they are wasting time.
Because placing engines across the wingspan is simply impossible now.
The most important thing is that only Li Zhen knows the most important reason. At that time, the engines that could be placed on the wingspan were not propeller engines at all, but turbojet engines.
What is the concept of a turbojet engine? That was a concept that none of them had been exposed to yet. Even Li Zhen is very vague.
Even now, it is impossible for Zhang to give Li Zhen a drawing of a turbojet engine, and he cannot explain it at all.
After all, Zhang Zhi is just an ordinary college student. No matter how academic she is, she will never be able to build a turbojet engine with her bare hands. That requires professional knowledge beyond conventional imagination.
And a propeller engine placed on the wingspan, this... actually won't succeed.
One problem they ignored. Putting it on the wings will increase the weight of the wings. In fact, the lighter the wings, the more lift they have. When two radial engines are added to the wings, the wings will instantly gain nearly a hundred kilograms of weight. If you want to fly smoothly, the power requirements for the engine are too high.
That is why only turbojet engines can be placed on wings, because the power of turbojet engines is far greater than that of propeller engines.
Li Zhen couldn't explain these truths to them. There was nothing wrong with being stubborn. Just let them try. Failure was considered experience.
Under Li Zhen's arrangement, the Institute of Motor Vehicles and the Aviation Institute entered into close communication again and began to cooperate on the first aircraft that could fly into the sky.
A week later, people from the Motor Vehicle Research Institute worked hard to debug the two radial engines, and the power difference was not big.
The Aviation Institute also spent this week constructing the fuselage.
They added steel tubes along the wingspan, which were connected directly to the fuselage to form veins of sinew.
Then the latest welding technology from the Electromagnetic Institute was used to weld the two radial engines to the wings.
After installing two propellers, the world's first real airplane was born.
Liu Jinghong was confident that he had sent out multiple invitations in advance, inviting political figures, wealthy businessmen, and scientists from all over the New Kyushu Kingdom to come and watch the test flight.
Everyone attaches great importance to this test flight.
If this test flight is successful, New Kyushu can officially announce that it has entered the era of aerospace.
Liu Jinghong also attaches great importance to it.
On the day of the test flight, a temporary airport runway that had been renovated from the Gale Tower was cleared and overcrowded.
Xun Shifei came, and the supreme commander of the Eastern Military Region came. Scientists from all over came. Even Yun Kexian, the former president of the National Academy of Sciences, came.
All the dignitaries came. The temporary takeoff runway was full of people standing on both sides.
A black car came quietly. Li Zhen got out of the car and sat in the pergola that had been set up in advance.
Xun Shifei stood up and shook hands with Li Zhen: "Congratulations, junior, this time the Kyushu Academy of Sciences will finally succeed in conquering the blue sky."
Li Zhen smiled and didn't say anything more. He sat down and drank tea.
The people sitting in the pergola took a deep look at Li Zhen and felt that Li Zhen didn't seem to be optimistic about this test flight, and they were thoughtful in their hearts.
After a while, the entire airport runway became completely noisy and full of people. Everyone tied their necks and looked towards the end.
A large tractor-trailer drove over carrying a huge object covered by canvas. The moment the canvas was lifted, a silver, streamlined aircraft with a sci-fi feel appeared for the first time and appeared in front of the world.
"Wow, so handsome."
"Is this... is this a plane?"
"silver."
"Is this the overlord who will conquer the blue sky in the future?"
"The information revealed by the Kyushu Academy of Sciences said that the name of this aircraft is Swordfish."
"Swordfish? Why swordfish?"
"Because you see how much it looks like a swordfish. The front is so sharp that it can stab someone to death."
"What a name, Swordfish."
"I don't know if it will work."
“…”
Liu Jinghong jumped out of the car and arranged for someone to get Swordfish off the trailer.
Then the staff of the aviation institute took various tools and began to conduct final measurement tests.
'buzz'
The moment the engine was turned on, everyone on the runway held their breath. Listening to the shocking sound of the engine and looking at the propeller that began to rotate at high speed, there was a hint of fanaticism in his eyes.
The moment the engine starts. The swordfish began to struggle uneasily, with dust flying behind it, like an angry dragon trying to ascend to the sky, struggling continuously.
If it hadn't been pulled by a rope from behind, it would have been full of surging power, and it would have wanted to rush out in an instant and jump up to the blue sky and white clouds.
