Although the sound of the engine and the wind roared in his ears, Lin Jinlai seemed to hear the exclamations of an unknown number of people behind him, he looked behind him happily, but he was immediately so frightened that he almost stopped breathing - there were more than a dozen ground crews on the runway running along the runway and shouting towards the plane, some people were waving their hands, some were waving their hats, and someone in the distance had already driven a Rolls-Royce to pick up the pilot, and was starting to chase this way, but no one could catch up with the plane. Of course, they didn't plan to chase the plane at all, everyone knew that they would definitely not be able to catch up, and in front of the road they were chasing, a wheel was rolling forward quickly on the runway, as if it was trying to catch up with the plane that had abandoned it, and finally lost its kinetic energy, and turned to the right on the runway, and rolled straight towards the hangar on the side. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 He nervously looked at the two nose landing gears of the plane, this reconnaissance trainer is a rear three-point landing gear, and the wheels running on the ground just now are the main landing gear wheels.

Sure enough, the wheels on the left landing gear were gone, and the empty landing gear poked there, looking terrifying. Yuan Zhenli obviously didn't notice that the wheel had fallen, and he didn't know if he should tell him now, after thinking about it for a while, Lin Jinlai still mustered up the courage to pat Yuan Zhenli twice on the shoulder in front of him.

Yuan Zhenli turned his head sideways, looked at Lin Jinlai behind him with a sad expression, and couldn't help but shout a little weirdly, "What's the matter?" ”

"The wheel is off!" Lin Jinlai could only shout loudly at this time, "Left front landing gear!" ”

Yuan Zhenli was almost scared, and hurriedly looked sideways, and sure enough, the left front landing gear was empty, and the wheels were really not on it. He couldn't help but yell at the back, "Where's the wheel? ”

"The wheels are off! Roll down the runway to the hangar! Lin Jinlai unconsciously pointed towards the hangar, but no one could see it.

What to do? Yuan Zhenli is really big now, and he has just taken off! The wheels just fell off, how could there be such a play? Whether it is the front three-point type or the rear three-point landing gear, the main landing gear must land first, if the rear wheel falls off, it is better to say a little, it is a big deal to drag it on the ground and force the landing, at most it is to scrape the tail and runway. But if the left front landing gear falls, once landed, the aircraft body will tilt to the left, and it will fall to the ground in a daze...... How?

The plane circled over the airport, Yuan Zhenli didn't come up with a solution at all, after a while, he looked at the fuel gauge, it was full, thought about it again, and shouted at Lin Jinlai behind him, "Write a note, let them not worry, we will go to scout, and the rest will come back." ”

Lin Jinlai rummaged in the locker in the back seat for a while, but found nothing, so he could only pat Yuan Zhenli on the shoulder again, "Chief!" No more paper! ”

"I'll go!" Yuan Zhenli was quite speechless, the notebook in the plane locker was a key supply, and no one was allowed to take it, and the person who could take it was He Rolling Dragon except himself. In fact, He Rolling Long was also quite speechless, he went to the Joint Staff Committee for a meeting this morning, but he couldn't find the notebook, remembering that he put it in the plane during the last flight, and asked the orderlies to get it, and the orderlies couldn't tell the difference between the front and rear seats, so they took the notebooks in the two cockpits.

He Rolling Long was standing next to the runway at this time, he didn't know what to do, there was no notebook on it, he couldn't be contacted, and the light signals and flags could only be shown to the people on the plane on the ground, and the iron box could only be thrown down to transmit. Suddenly, as if he remembered something, he shouted at the orderly on the side, "Go quickly, go to the duty room to see, is Chief Yuan's mobile phone in the duty room?" Without saying a word, the orderly rushed over to the duty room, so fast that he could almost bring out a puff of smoke from behind.

The ground staff and trainee pilots on the runway were all looking up at the plane still hovering in the air, and Yuan Zhenli and Lin Jinlai on the plane were also looking at the crowd on the ground, and neither side had any way to contact each other. Suddenly, Yuan Zhenli felt a vibration from the flight suit, and he thought that the vibration had increased due to the increase in engine power, so he hurriedly looked at the speed, and the speed was normal.

At this moment, Lin Jinlai, who was behind, patted him on the shoulder and shouted, "Chief, they asked you to look at your phone." ”

Yuan Zhenli couldn't help grinning, he was originally not allowed to bring his mobile phone on the plane, but he forgot to put it back when he conducted the flight inspection today, so he didn't know if he brought it on the plane. He hurriedly took out his mobile phone, and it was indeed a call, Yuan Zhenli shouted at Lin Jinlai behind him, "You come to drive!" As he spoke, he closed the clutch for the rear seat operation.

Although Lin Jinlai was still a little scary when he landed, there was no problem with this kind of level flying hovering, and the joystick began to operate generously.

"Hey!" Yuan Zhenli connected the phone, and it was He Rolling Dragon on the other end, "Your wheel has fallen!" ”

"Nonsense, I know, how did it fall?" Yuan Zhenli shouted at the microphone rather angrily, He Rolling Dragon spread his hands, but Yuan Zhenli couldn't see it, "How do I know how it fell?" I had just come back from Bunker Hill and I heard that you had taken off, and then the ground crew told me that one of the wheels had fallen off. ”

"I'll go! Don't worry about it for now," Yuan Zhenli looked at the battery of his mobile phone, "My mobile phone is running out, there is still about 30% of the battery, I will turn off the phone first, and fly directly to the west to see the enemy's situation." ”

"And what about you landing?" He Rolling Long was speechless for a while. "What else can I do? Cold! Even if you land now, it's just as dangerous, so let's go and see what the situation is going on over there. We brought cameras and a few bombs, and after the reconnaissance we would attack them, and we would burn fuel on the way and throw the bombs, so as not to lose some weight so that we would not fall upside down when we landed. ”

"Yes, then you pay more attention, and we'll get in touch when we land." He Rolling Long said as if he suddenly remembered something, "Isn't there a USB port reserved on your plane?" Isn't it possible to charge directly? ”

"I know there's an interface, but I don't have a cable, what if the cable falls into the plane and gets stuck? You don't usually bring the thread with you, do you? Yuan Zhenli shouted loudly into the phone, "It's going to die!" Don't bring it next time! ”

He Rolling Dragon hurriedly defended, "I didn't bring it!" Why am I carrying my phone on the plane? If you can't hear the ringtone and don't have GPS navigation, you pay attention to safety, we are waiting for you to come back. Not to mention, save electricity for you. ”

"Okay, I'll turn it on when I return, and I'll send you a text message when I enter the range of Dongfang Port." He Rolling Long hurriedly said, "Okay, no problem, waiting for your news!" Bon voyage! ”

Yuan Zhenli hung up the phone and turned off the phone directly, then stuffed the phone into the flight suit, and shouted loudly with Lin Jinlai behind him: "Modify the course and fly west along the river!" ”

Since the establishment of the Oriental Port, the aircraft has reached the third generation, from the beginning of the slightly stronger people sit in and can't stretch their feet like a bee-like plane, to the temporary manufacture of a reduced version of the mosquito plane, and then to the current biplane reconnaissance plane, the aircraft industry has made great progress. According to He Rolling Long's concept, he also wanted to build a large airship or hot air balloon for the airborne troops to facilitate the transportation of a large number of materials and personnel. However, the hot air balloon is very affected by the fuel, and has no power, a bit of flying with the wind, if it is used for artillery observation these aspects are quite suitable, for fixed-point transportation or something is not suitable. In contrast, airships are far better than hot air balloons and transport planes, except for the slower flight speed, the carrying capacity is far more than both, and the requirements for airship take-off and landing sites are not high, which is much simpler than building an airport.

However, despite all the benefits of airships, they have the same constraints as other Senate black technologies - there is no guarantee of airtightness and gas used in the shell of the airship. There is no plastic in this space, and if you want to make an airship shell, you can only choose canvas now, and canvas waterproof can also be considered, but it is basically impossible to prevent air leakage, and even if you can provide rubber to apply the inner layer in the future, it is difficult to guarantee that it will not leak. Even airships from the old planes couldn't solve the airtightness problem, but they could just take a gas canister and fill it with gas when needed. And the gas is also difficult to choose, at the beginning everyone is optimistic about hydrogen, hydrogen is indeed a good thing, it is very simple to make, and it is not troublesome to store, but the biggest danger is that hydrogen is combustible, and once it burns up, it is simply impossible to extinguish, the Hindenburg airship of the old time and space caught fire in only thirty-two seconds, and more than 30 people were killed, the reason is that the hydrogen on the airship burned. The gas later used to fill the airship in the old spacetime was mainly inert helium to ensure that no fire would occur.

However, the acquisition of helium was a big problem before, and helium is a super noble gas, which basically does not react with other elements, and can only be extracted, not produced. There are four main methods of helium extraction in the old space-time: natural gas separation and helium extraction; Air liquefied fractionated helium; Uranium ore roasting, fractionation and purification and synthetic ammonia tail gas separation and purification. Shi Li has already stated at the discussion meeting that the synthetic ammonia production line is about to be put into operation, and the synthetic ammonia tail gas can get helium as long as it is passed into the acid, and as long as the metallurgical department solves the problem of the gas storage tank, the production process can be started. Li Jin also expressed his attitude at the meeting that compared with the products produced when the factory was just established, the purity of the steel of the Dongfang Iron and Steel Plant has been getting better and better, and the quality of the steel will basically meet the quality standards of similar products of the Capital Iron and Steel Plant before the old time and space steelmaking within half a year. The most important thing now is to solve the problem of airship airtightness. However, since Shili's chemical plant was put into operation, his waist has hardened a lot, and he swore that he would give him half a year, and ensure that the focus of the Senate's work would be tilted towards his chemical department, and that he would be able to make plastics, which made most of the departments in urgent need of plastics reassure him that if he can really do this, then the chemical department will be absolutely given priority.

============================= divider =============================

The plane flew west at a speed of about 160 kilometers per hour in the air, Lin Jinlai behind was in charge of flying, and Yuan Zhenli was holding a telescope to observe in all directions. Under the plane is a river that meanders from the west, and this river does not have a name, because the Wu Dynasty and Champa are bounded by the lower reaches of this river, so it is directly called the boundary river. The middle and upper reaches of the river are the dividing line between the north and the south of Annam, and although both sides have always insisted that they are the orthodox of Annam, they have to stop at both sides of the river. Although this river is nothing to the Yangtze River, Yellow River and Pearl River, which are commonplace for the patriarchs, the two banks of the rock have been washed away by perennial floods, and the rocky banks have been washed into strange rocks, and it is basically impossible for people, vehicles and horses to enter, but this time and space has become an insurmountable natural defense line. It is only about 10 kilometers or so that there is a sandy beach near Jiezhen that can guarantee traffic, so Jiezhen has become the pearl of the defense line of the north-south Annan boundary river.

Since the Joint Chiefs of Staff did not have a complete understanding of the terrain to the west, the cameras installed on the aircraft were activated at this time and began to photograph the terrain that could be seen during the westward flight. The camera also has a small compass mounted on the lower part of the lens to determine the direction of the shot and facilitate mapping. The flight altitude was also about 200 meters, which is more suitable for shooting videos, and the temperature at this altitude did not drop too much, at this time, the sun was shining on them overhead, and the dogskin hat and leather jacket began to make sweat beads appear on the foreheads of both of them.

Compared with the pilots of the old time and space, they were synonymous with handsomeness, and the two pilots in this time and space, dressed like farmers in Shaanxi, enjoyed a journey that was definitely not comfortable. First of all, the wind is too loud, the speed of 160 kilometers per hour, although the supercar in the old time and space can reach about 300 kilometers per hour, but people don't drive convertibles to achieve this speed after all! When you drive on the highway, you can feel the roar of the air when you open the window.

Although both of them were now wearing earmuffs to protect their voices, they were still tormented by the roar of noise. Yuan Zhenli routinely looked left and right with the telescope for a while at this time, then leaned back and muttered, "How many hours are left...... The seat behind him is wooden, but it is padded with a layer of cloth filled with cotton, and the X-shaped seat belt is pulling his shoulders tightly at this time, "How much use is this seat belt?" If there is a mechanical failure, I am afraid that it will be quite troublesome to even get out of it. Grunting a few words, he shouted behind him, "How long have we been flying west?" ”

Lin Jinlai hurriedly looked down at his watch and replied loudly, "It's been one hour and fifteen minutes!" ”

"Has the airspeed always been 160 km/h?" Yuan Zhenli rummaged for a while, and then remembered that the flight record book was not there, and quickly replied, "Yes, chief!" ”
