"Get on the plane and take off!" Mr. Ma gave the order directly.

Xie Kai and Tian Li also followed on the plane.

This is Xie Kai's first time stepping on the Yun-10, although it is a test aircraft, there is no difference from the layout of a civil airliner.

Behind the cockpit, there is the first class, and the back section is all economy class.

"You put your parachutes on your backs. As soon as he got on the plane, Cheng handed Xie Kai and Tian Li a parachute from time to time.

None of the technicians on the plane took it.

"Isn't there anyone else?" Xie Kai looked weird, "Although this plane has only flown for more than 170 hours, I believe in the safety performance of this plane when it flies." ”

Xie Kai did not believe in the safety performance of the aircraft.

He knows that many structural parts that need to be manufactured as a whole are assembled.

But at this time, he can't do this in front of the chief designer, deputy chief designer and many technicians, even if he has the urge to put on a parachute on his back.

"It just makes you feel less nervous. Without you, this plane really can't fly. Ma Fengshan said to Xie Kai, "We just hope that you can experience this flight easily." ”

"Mr. Ma, don't worry, I'm not so timid. You're not afraid, but what am I afraid of? Although I don't believe in the safety of this plane, I believe in you. Xie Kai told the truth.

A few days ago in conference room 404, Xie Kai directly pointed out the defects in the manufacturing process of Yunshi, which is a potential safety hazard.

Ma Fengshan and others used their practical actions to prove that their technology is trustworthy.

This method is not advisable, but Xie Kai understands that the whole team is on the plane just to tell himself that the safety of Yun-10 is reliable.

Otherwise, Xie Kai would not have parachuted when he got on the plane, and no one else had this thing.

"This flight experience is at least much better than the Z-5, and it is much better than the leaky cockpit of the Yun-8, but the disadvantage is that the cost of a ride is too high. Xie Kai used a smile to hide the nervousness and fear in his heart.

Silently prayed to the gods and Buddhas all over the world to ensure that Yun Shi would never have an accident on this flight.

Optimism is a good thing, and blind optimism brings disaster that cannot be saved.

He couldn't really get on the parachute in front of Ma Fengshan and others.

Even Xie Kai thinks that as long as Ma Fengshan persuades and persuades himself, he will borrow the slope to get off the donkey and get it on his back.

Ma Fengshan didn't insist anymore, which made Xie Kai a little disappointed.

In just half an hour from the time Yun Shi landed to the time he took off again, the people on duty at the airport garrison, as long as they could see the plane, saluted the plane when the plane's engine roared, and watched the huge plane rush into the dark sky on the runway......

"Don't worry, it won't fall!" Tian Li sat next to Xie Kai, seeing that he was nervous, she gently held Xie Kai's hand to comfort him.

Her palms were cold.

Xie Kai knew that Tian Li's nervousness was even worse than his.

The situation that happened when she sat up straight and came over just now was not because she was airsick, but because she was afraid that Zhi-5 would fall.

It's not that Xie Kai is timid, before he was reborn, he didn't take a few planes, after all, he didn't have much time to go out.

In this life, on the last trip to Xiangjiang, he took planes one after another, even if he behaved very calmly, the worries in his heart were not alleviated.

From the moment the plane began taxiing on the runway, he was worried that the plane would break down.

When the nose of the plane was raised and the nose landing gear was off the runway, until the plane was fully flying, Xie Kai's heart hung in the air.

The plane encountered air currents at high altitude, and even if the flight attendant reminded them that there would be bumps, he did not dare to relax. I was always thinking about how to save my life in the event of a plane crash.

I always felt that the plane would break down in the next moment, and it fell from a height of 10,000 meters.

Airplanes are not like cars and trains, they are always at an altitude of 10,000 meters, and if they fall, they will be crushed to pieces, and there is no possibility of survival.

On the ground, even if something goes wrong, there is still a good chance of survival.

Some people say that airplanes are the safest means of transportation in the world, and Xie Kai scoffs at this, trains are. Although there are a lot of car accidents every year, the number of cars in the world is compared to the number of airplanes, and the proportion of airplanes is terrifying......

Therefore, Xie Kai is afraid of taking a plane from the bottom of his heart.

When he went to Xiangjiang a while ago, when he got off the plane, his legs were weak, and Tian Li, who helped him get off the plane, naturally knew the situation.

Taking a civil airliner, Xie Kai was so worried, not to mention that this Yun-10 still only flew for more than 170 hours, and the main core components of the design requirements for the overall manufacturing were all assembled and other technologies, and there was no test flight completed, and there was no finalized aircraft?

"Why don't you put the parachute on your back?" Ma Fengshan sat next to Xie Kai, seeing Xie Kai's face pale, his teeth clenched, and asked with a smile, "It's not a shame, and no one will look down on you, you are just a child." It's us, always worried, afraid of any glitch!"

"We were afraid of a breakdown because if it did, the project would be terminated completely, not because we feared for our own lives. Cheng continued Mr. Ma's words from time to time.

"I know!" Xie Kai nodded, "I don't want to be scared either, maybe it's because I don't fly too often." ”

The number of times is one thing, and the bigger concern is the manufacturing defect of Yun Shi.

The design was successful, but the production technology couldn't keep up with the design.

"From the first first flight, the Yun-10 is the 131st flight test. In 81, it flew to the capital, and then flew to the Northeast Ice City on April 25, 83, with a range of 1,840 kilometers, and on November 4, 83, it did a long-distance long-distance test flight with a maximum take-off weight of 110 tons and a commercial load of 15 tons, with a range of 3,680 kilometers...... This year, I flew to the Qinghai-Tibet Plateau seven times in a row, and there were no failures during the flight...... "Ma Fengshan introduced the test flight process of Yun 10 to Xie Kai. "There were no emergencies even during the flight. ”

Every test flight, Ma Fengshan remembers it very clearly.

He hoped to reassure Xie Kai of his concerns.

"Mr. Ma, I'm really not worried about this. Xie Kai felt that he was too timid.

When his feet are not on land, he always feels insecure.

"By the way, what do you think about the next step of Yun Shi?" Xie Kai simply changed the subject. "With the current situation, it is difficult for Yun-10 to obtain an airworthiness license from the Civil Aviation Administration, and it is impossible to promote it to the civilian market. ”

The future of Yun Ten is very important.

Xie Kai didn't want Yun 10 to be finalized after the test flight.

"Originally, at the beginning of the test flight, the question of future modifications was discussed. At present, it does not seem appropriate, and 404 cannot support such a large amount of funding. Ma Fengshan said with some regret, "If the country agrees to our plan and allocates enough funds to complete the rest of the test flight work, it can be finalized." ”

"If the plan of the Third Machine Department in 81 is approved, 90 years ago, can 16 planes really be delivered?" Xie Kai thought about the news he knew, "What you applied for was to invest 170 million yuan for Yunshi before 85 years, and at the same time you also need 160 million working capital, a total of 330 million ......."

Xie Kai wanted to know if the truth about Yun Shi's dismount was like the rumors.

Originally, only a very few people knew the truth about all kinds of analyses, all kinds of discussions, and all kinds of scolding.

There is nothing more real than asking the chief designer of Yun Shi.

The Third Machine Department applied for 330 million funds in 81 years, but it was not approved, but later some people speculated that Yun Shi died because of 30 million funds.

Ma Fengshan's face was a little embarrassed, and Xie Kai's question couldn't be avoided.

At first, he opposed Dongfeng Cheng's meddling in the Yun 10 project, and finally threatened Zheng Yucheng and others to take over Yun Shi.

His thoughts, Ma Fengshan and others are not clear.

"Of the 330 million, 170 million yuan is invested in building factories and production lines, and the remaining 160 million is used for flight test experiments and design modification funds, including engine test funds and research funds...... "Mr. Ma did not hide it.

Only half of the test flight tasks have been completed, and the engine has not yet been fully developed, and it is impossible to finalize it with only 30 million funds.

"That is to say, if we do not carry out modifications and only produce based on the technology and design of this aircraft, the minimum investment is 330 million?" Xie Kai asked.

He wants to know how much money it will cost for Yun Shi to really put into manufacturing and put it on the market.

"Not only that, but these are just the basic investment, design modification, and the cost of experimentation. Mr. Ma said, "To enter the production process, a plane must prepare at least 20 million manufacturing funds, if the test flight process needs to be modified, upgrade the system, etc., it may be more expensive......

"So cheap?" Xie Kai was a little incredulous. "Don't all used Boeing 707s cost fifteen million dollars?"

After Nixon's visit to China, China imported 10 707s from Boeing for civil aviation transportation, and the total contract value of 10 Boeing 707s was 125 million US dollars, with an average of 12.5 million US dollars per Boeing 707.

Since then, the price of the 707 has been rising.

At the current cost, the performance of the Yun-10 is comparable to that of the Boeing 707, and if the manufacturing cost of a plane is 20 million, this is less than 10 million dollars, even if the price increase is counted, it will not exceed 30 million.

"The production cost is not high, and if the quality of the spare parts is guaranteed, the cost can be reduced. However, the price cannot be calculated in this way, and the research and development costs and infrastructure investment have to be diluted into the cost. So far, we have invested more than 500 million yuan in large aircraft, and the one we are sitting on can be said to cost more than 200 million or nearly 300 million ......," Ma Fengshan explained to Xie Kai.

"That's just as well. However, we do not count the cost of state investment, only the money invested by 404. Xie Kai said, "The country's cheapness is not taken advantage of." ”

The two communicated, so that Xie Kai was not as nervous as he was at first, and after diverting his attention, he didn't have the heart to worry about the plane crash.

"Are you preparing to give birth?" Ma Fengshan heard this, with a look of hope.

Only by going into production can the aircraft project be more promising.
