"Tell me a little bit more about the plane, can it be like a tank, can it participate in combat?"

Bai Yu didn't want to let this state continue, he didn't like this feeling, as if no matter how hard he tried, he couldn't catch his sweetheart, and could only watch her stand on the other side of the distance.

It turned out to be linked to the military aspect so quickly. Gu Shuhan smiled helplessly, the piston propeller plane she built was a genuine civil aircraft.

However, many new industries in history were mostly used in the military at the beginning, and it was not until after the war that they extended to people's lives. It is not surprising that Bai Yu would have this question.

Gu Shuhan, whose thoughts were pulled back, did not continue to remember the deceased, she said to Bai Yu seriously: "The aircraft we just developed does not come with ammunition and defense systems, it can drop bombs at high altitudes, but the efficiency is not too high, and it ...... analyzed from the performance point of view."

Piston propeller machines, as the name suggests, have their forward traction generated by the engine driving the propeller to rotate. The speed of the propeller is limited, and the drag generated by its flight also limits the speed of the piston propeller, so the piston propeller aircraft are not suitable for high-speed flight. In war, an attack from above can certainly play a role in disrupting the enemy's forces, but in the absence of various technical problems, airships and piston propeller aircraft can play a limited role.

However, in the aviation industry, which is just beginning, the piston propeller machine is already a very advanced aircraft. It is much safer and more maneuverable than clumsy, low-speed, flammable and explosive airships.

Like the Wright brothers' aircraft, the original piston propeller aircraft at the Gu factory were wooden. The structure and construction of the wings and fuselage are much simpler than in later generations. Due to the small power of the piston propeller itself, the fuselage of the aircraft cannot be too large, and the materials selected cannot be too heavy, otherwise, the engine will not be able to drive the aircraft to fly.

In the era of turbines in later generations, most of the materials used in the fuselage were light metals such as aluminum alloy, magnesium alloy and titanium alloy, and the landing gear had to withstand great impact force when the aircraft took off and landed, so it was necessary to use ultra-high-strength structural steel to make it. The wing structure of the turbine is also much more complex than that of the original piston propeller, and the leading edge flaps, slats, ailerons, spoilers, winglets, etc., all need to be made of special materials. And where do these materials come from? It is simply unrealistic to produce all of this all at once.

For Gu Shuhan, theory has never been a problem. But in the case of materials and mechanical equipment that do not match reality at all, even if she is superhuman, she will not be able to produce a turbine shaft machine.

Moreover, aircraft are not like cars, as long as they are built, they can be used. With an airplane, do you want a guidance system? Do you want navigational aids? Do you want a shuttle bus or boarding bridge? Even if none of this is taken into account, at the very least, a runway for take-off and landing and the surrounding clearance area are always needed.

With the advent of aircraft, there is a need for a whole system around it to serve it.

In order to make the turbine operate normally, from the collection of raw materials, the production of high-tech materials, the production and assembly of spare parts, the production of aviation kerosene, the production of navigational aids, including the construction of airports, and the development of air routes, everything needs to be done little by little, which is not a one-time thing.

"I understand, it's me who is anxious." After listening to Gu Shuhan's words, Bai Yu understood in his heart that aircraft, as an emerging product, would inevitably bring a great change to the surroundings. He believes that what he hears and sees is only the tip of the iceberg.

"I will tell my father and Uncle Qin about this, and when the time comes, they should still ask you about the plane. It's going to be a huge project, and you're going to need government funding, aren't you? ”

Premier Bai and Qin Lao have always held a supportive attitude towards Gu Shuhan's research, not only because Gu Shuhan can make them really profitable, allowing them to maintain their international competitiveness and gain a lot of money at the same time, but also because her research and innovation spirit have led to a wave of domestic innovation. While the former is important, the latter cannot be ignored.

As long as we maintain this good atmosphere, we can see hope.

For Gu Shuhan, loans are now commonplace, and she makes more money and spends more money. Now, Prime Minister Bai has relaxed the loan amount a lot. If the amount is within a certain amount, the bank can lend to her; Once the amount exceeds the limit, she must first get approval from the government before she can receive financial support.

Generally speaking, as long as Gu Shuhan comes to the door, the government will lend her a loan. Because none of the money invested in her has ever been a loss.

"Okay, then, I'll leave it to you to communicate with the Prime Minister." Gu Shuhan closed the information in his hand.

When Bai Yu heard this, he couldn't help but smile.

His girl is very strong, and no matter what happened to her before, she would not trouble others if it was unnecessary. She didn't know how much he wished he could be troubled by her. Now, she seems to have finally learned to rely on him, is that a good start?

When Bai Yu stepped into the office, the sun was already setting in the west. Now, after a long talk between the two, before they knew it, the night was dark.

Putting Wen Jiàn into a drawer, locking the doors and windows, Gu Shuhan looked up, and saw half of Bai Yu's side face. The moonlight softened his corridor, and it wasn't until he saw his blinking eyelashes that Gu Shuhan suddenly realized that she was so close to him.

As if sensing something, he raised his eyes, and Gu Shuhan was just crashing into his eyes, and she could catch the warmth overflowing in his eyes as clear as autumn water.

"It's late at night, I'll send you home."

A short sentence quickly escaped into the air. But then, a hand came to her side and grabbed her hand.

Now the weather has turned cold, the evening breeze is wheezing, and her hands are a little cold.

Seeing that the tentative action was not refused, he became bolder, and simply wrapped her hand completely in his palm and clasped it firmly.

"Do you really like me?" After a while, a female voice sounded beside Bai Yu, the voice was cold, with Gu Shuhan's usual coldness, but after all, it was a little different from the past.

"Of course, I told you a long time ago that I ......" He suddenly became cramped, perhaps realizing that this was an opportunity to change the relationship between the two, and that he could speak well in the past, but at this moment, he couldn't play it at all.

"But I'm still a married woman." Gu Shuhan broke away from Bai Yu's hand.

Bai Yu: "...... Yes? He was stunned, as if he didn't understand why the topic had jumped to this point all at once.

A smile flashed in Gu Shuhan's eyes: "So, you can wait for the time being." She waved at him, "My home has arrived." ”
