It's OK.

Zhang Nan solved the various improvements of the "Mengfei Type 1" aircraft.

Yang Mengchao obtained light and tough carbon bamboo silk material, which can greatly reduce the structural weight of the aircraft.

Combining the two, it’s no problem to create a perfect aircraft.

...

June 8th.

Mengchao Aircraft Manufacturing Factory.

Zhang Nan drove the No. 3 prototype that had been transformed by him, and landed very smoothly and dexterously on the temporary runway next to the factory.

"Is this our No. 3 prototype?"

Yang Mengchao rubbed his eyes, looking surprised and disbelief.

The shape and lines are smoother.

The waistline has become thinner.

Many details that are not easy to detect are added: such as the wing cutter on the wing, the small texture of the fuselage, as well as the cutting tips and thinning treatments in certain parts.

The first impression I give is perfection. No matter what angle I look at, I feel very pleasing and pleasing to the eye.

It even has a certain artistic beauty and elegant temperament.

"Zhang Nan, in your hands, how did the No. 3 prototype become like this? How did you do it?"

Pulling Zhang Nan's arm, Yang Mengchao asked impatiently.

"Don't ask, I can't answer one by one. This is the "Improvement Manual" I have summarized. I have taken notes on more than a thousand improvements. You can take them over and read them slowly."

Zhang Nan took out a thick notebook from his pocket and handed it to his hands.

"And even if you don't find the so-called carbon bamboo wire material, the empty weight of the No. 3 prototype was cut to a level of more than 2 tons, and the weight could not be reduced even by 1 gram. The maximum flight speed, maximum range and other data all meet the standards. For maintenance, I can do whatever it takes to repair it. I have reserved a lot of fuselage openings, which should be easier to repair."

Zhang Nan added.

"This...how is this possible?"

Yang Mengchao felt that his head was a little overturned, "What you mean is that as a test pilot, you have improved this aircraft to a perfect level with your own strength. Even without carbon bamboo silk material, it can meet data indicators and meet customers' demanding requirements?"

"That's right, that's what it means." Zhang Nan nodded.

"Impossible. You are not a mathematician and don't understand the principles of flight very well. How could you be so powerful?" Yang Mengchao shook his head crazy.

"Maybe this is a kind of talent. I suddenly became enlightened and reached the state of 'man-machine integration', and learned how to modify it without a teacher." Zhang Nan shrugged.

Yang Mengchao's eyes were about to fall off, and he could not accept such nonsense explanation. He wanted to grab Zhang Nan's collar and find out the truth.

But no matter how he doesn't believe it.

Zhang Nan took him on the plane and took him to the sky for a long time. After experiencing the 800-kilometer-hour speed, the plane was not separated.

Back at the ground, he looked at Zhang Nan as if he saw a living monster.

And the great gods who must be offered.

"Zhang Nan, no, Zhang Shen, don't call me the instructor in the future, just call me Lao Yang."

Yang Mengchao patted his shoulder and said with an extremely kind attitude: "In addition, as the chief ace flight officer of Mengchao Aircraft Manufacturing Factory, you can give you 30% of the shares of this factory. If you think there is less, you can add it. What do you think about Zhang Shen?"

"Old Yang, your smile makes me feel a little philandering."

Zhang Nan said lightly: "I really don't want any shares. In the future, I'll get a few more planes for me to play with. If my farm expands in the future and needs plane seeders, pesticide sprayers, etc., you can just help me customize a few... You should have helped me with this little favor, right?"

"No problem, I'll order you all for free!"

Yang Mengchao said while patting his chest.

...

soon.

The No. 3 prototype improved by Zhang Nan was selected as the final finalizer, and the No. 4 prototype was abandoned without a test flight.

What we need to do next is to combine carbon bamboo wire materials to achieve further weight reduction based on the appearance of the No. 3 prototype to the extreme based on the huge advantages.

So in order to pursue a "perfect" plane, Yang Mengchao, Zhang Nan and others were busy until the end of June.

With the help of the lightweight properties of carbon bamboo wire, the air weight of the aircraft has been reduced to a minimum of 1625.8 kg, which is truly undecreased.

With Zhang Nan's abnormal ability, he made more than 100 improvements to the aircraft, and every detail was polished to the extreme perfection.

July 1.

Mengchao Aircraft Manufacturing Factory successfully achieved a finalization of the first aircraft developed in half a year - the "Mengfei No. 1" single-engine propeller aircraft.

The main technical parameters are as follows:

Length: 9.21 meters

Wingspan: 10.42 meters

Height: 3.5 meters

Empty weight: 1625.8 kg

Maximum flight speed: 872 km/h

Maximum range: 5830 km

Maximum crew: 2 people

The above technical parameters are quite outstanding. Not to mention ordinary civil aircraft manufacturing companies, even military aircraft manufacturers with extremely strong technical reserves and strength, they may not necessarily build such outstanding aircraft.

So when the performance introduction of this propeller aircraft appeared in the relevant experts from the Ministry of Science and Industry and the Air Force technicians of the Ministry of Defense, their first idea was to not believe it.

It's definitely a fraud!

Cut off the relevant performance indicators by half, which is more credible.

"If you don't believe it, you can send someone to experience it."

Yang Mengchao even said in a little fluttering tone: "If the data I listed is mixed with even 1% false, I am willing to accept the punishment. I will not build aircraft in the future, but specialize in toilets. If my 'Mengfei No. 1' aircraft is indeed so good, please purchase more aircraft and allocate a batch of equipment and workers for me. I want to expand the production line and achieve mass production!"

...

July 5,

The expert group of the Ministry of Science and Industry and several air force representatives from the Ministry of Defense came to Mengchao Aircraft Manufacturing Plant.

Their expressions were very serious, just to see how crazy the factory director Yang Mengchao, who spent only half a year to build an advanced plane that was so arrogant that he could be so arrogant.

If the performance indicators of "Mengfei No. 1" do not meet the performance indicators listed in the parameter table, then the aircraft manufacturer will indeed be converted into a toilet factory in the future to solve the problem of serious shortage of toilets within the Kaituan Bureau.

"Let's get started."

As a test pilot, Zhang Nan brought an expert from the Ministry of Science and Industry to heaven.

The Air Force representative of the Ministry of Defense sent two pilots to learn how to control it in a short time, and drove another "Mengfei No. 1" and accelerated the launch.

More than 5 hours later.

After the test flight was finished.

Experts from the Ministry of Science and Industry concluded that it is fragrant, it is really fragrant.

The Air Force representative of the Ministry of Defense concluded that the magic machine is so delicious!

After learning about the characteristics of "Mengfei No. 1" such as "easy to learn, easy to control, easy to repair", I placed an order, and there was nothing to hesitate to place an order immediately. It would be unreasonable not to buy such a good plane.

The Ministry of Science and Industry has placed an order of 1,200 aircraft and hopes to be delivered within one year.

The Ministry of Defense has placed an order of 1,500 aircraft and hopes that all of them will be delivered within one and a half years.

The total orders are nearly 3,000, which is enough for Mengchao Aircraft Manufacturing Factory to work overtime for a while.

If the civil market is allowed to be liberalized later, "Mengfei No. 1" will definitely become a must-have for every pioneer like a private car, and it is entirely possible to sell millions or tens of millions of aircraft - if there are no competitors in the market.

However, no matter how many racks the "Mengfei No. 1" can sell or how much success it has in the market, it has nothing to do with Zhang Nan. He will not make 1 cent of money from it, and he doesn't care much about these things.

Fortunately, Yang Mengchao fulfilled his promise and, in accordance with what Zhang Nan said, led several technical workers. It took more than half a month to build the flying car that Zhang Nan wanted on July 15 and named it "Nan Fei".

The size of the ‘Nanfei’ is one circle larger than that of the ‘Mengfei No. 1’, with three rows and five seats, and can accommodate up to 5 people.

The interior is gorgeous and very high-end.

The panoramic view is a bubble-type cockpit without partitions. It has a great view when viewing the scenery outside the window. There are telescopes for viewing the ground scenery in front of the seats.

For the engine, Zhang Nan made a major transformation of a 600-horsepower six-cylinder piston diesel engine and filled the six piston cylinders with water, and then inserted six so-called "nuclear batteries" - which are actually the energy clusters in Zhang Nan's body.

When Zhang Nan releases 3 units of light energy per second into six cylinders, each of which releases 3 units of light energy per second, the output power of this engine can reach more than 500 horsepower.

When 5 units of light energy are released per second, the engine power can exceed 1,000 horsepower.

In short, considering the maximum bearing capacity of this engine, as long as the output power does not exceed 1,800 horsepower, the engine can be used at will without the risk of explosion of the cylinder.

With this engine power, the "Nanfei" can fly for nearly a thousand kilometers per hour, which can be said to be quite fast.

In addition, there is no device such as a fuel tank, so there is no need to load fuel, and the fuel tank is transformed into a huge storage box with a capacity of 1.5 cubic meters and can accommodate a large number of luggage items. Although Zhang Nan has a space ring, avoid using it as little as possible.
