Development of productivity started in 1981

Chapter 90 Aircraft Manufacturing Part

Returning to the underground base on Sunday night, Wang Jiankun showed Zhizi the air flow images recorded during the daytime flight in his mind, asking him to make further improvements to the aircraft based on the data.

Because Tomoko will be required to design a seaplane capable of subsonic flight in the future, the airflow diagrams obtained from these actual flights can provide Tomoko with the most accurate data.

He used the base's microwave to heat up a can of meat and rice for himself, then contacted Cheng Xing using a text message machine to ask him whether the shipment had been loaded and shipped.

"Jiankun, your batch of goods has been dispatched. I followed the station staff to load the goods. I stacked them according to the instructions and handled them with care. Don't worry. But you have to send someone to watch over them at the station, otherwise the staff will not treat your goods so gently."

"Okay, thank you Cheng Xing. I will tell my uncle about Guangshi and he will arrange someone to keep an eye on it."

"How's your business in lighters and digital watches lately?"

"Wholesale of lighters is currently growing steadily. The export business that my brother Cheng Yong is following has been slowly increasing recently. Domestic wholesale has not seen much growth, but the electronic watches wholesaled from your Xingyao Electronics are very popular. Every time I receive a batch of goods, they are sold out within a few days."

"Oh? How come digital watches are selling so fast? We can't have so many wedding requests here, right?"

"Of course not. But people who are not married also buy this kind of electronic watch. After all, young people nowadays feel ashamed if they go out without a watch. Our electronic watches cost less than a month's salary. Those who have jobs can still afford it if they save a little. And as long as one person buys it, other friends and colleagues will buy one every ten days or half a month. After all, they don't need tickets, right? Of course, the majority of them are sold wholesale to small towns, accounting for 60% of the current shipments."

"Oh, I thought so. However, Xingyao Electronics is expanding its production. You'd better control your prices. In two months, the shipment volume will increase. You will not be able to sell at the current retail price. So don't stock up too much."

"Well, we know that. You told us before the New Year that you would expand production this year. We buy in batches and only buy the next batch when they are almost sold out. We don't stock up too much."

"That's good. Go ahead and get busy. We may see new designs of lighters next month. You can take some out for trial sales and then give feedback to my dad. We will then make more of the models that sell well."

"Okay, bye then!"

After contacting Cheng Xing, Wang Jiankun sent a message to his uncle, letting him know the departure time and train number of the goods so that his uncle could arrange someone to go to the station to receive the goods.

In the evening, Wang Jiankun manufactured some lighter production equipment, such as 14 stamping machines, 8 sets of painting equipment, 20 sets of assembly workbenches and tools, and also manufactured the second set of spring production equipment. He manufactured more assembly tools because the stamping speed has increased a lot since the use of rolled iron production, and the number of assembly tools has to increase accordingly.

Wang Jiankun will transport these equipment to the scrap recycling station in the next half month, and then have his father's fleet transport them back to Fengshan Commune and Wangjia Production Team.

Because yesterday when my father came to deliver the goods, he told Wang Jiankun that the electric poles leading to the Wangjia Production Team were already being laid, and it would probably take less than a month to complete. Then the second lighter production factory in the production team had also laid the foundation and was building the walls. The second phase of the commune's spring factory was also under construction, and it would probably be completed by the end of March.

So Wang Jiankun was afraid that he would forget, so he took advantage of this period of time without having to waste his energy on excavating the base and quickly manufactured these mature equipment, and then let his father slowly transport them back.

The next day was Monday. In the morning, Wang Jiankun asked his class teacher, Teacher He, for a week's afternoon off. That meant that Wang Jiankun would not attend classes from Monday to Saturday afternoons. Teacher He said nothing and approved it readily. After all, he still attended half a day of classes every morning.

So what did Wang Jiankun do when he took leave? Of course, he went to practice flying. After all, proficiency is accumulated over time. The next step is to fly faster planes. If you don't practice some basic skills on a slow plane, it will be more difficult to practice later.

On Monday afternoon, after Wang Jiankun finished his lunch at school, he quickly rode his bicycle and changed to a speedboat to rush to where the plane was parked.

It was less than 1 o'clock when we arrived. The sun was high in the sky. The wind speed was only about level 1 at this time. The water surface was sparkling. It was a good weather for flying.

Before taking off, Wang Jiankun made a model of the new airplane that Zhizi had designed last night, and planned to take it to the sky to test it to see if the design was reasonable.

After the manufacturing was completed, Wang Jiankun temporarily fixed the model on the back of the aircraft, preparing to open the fasteners to release it after reaching a high altitude, and tow it with the CJ-1 to fly.

Then he added the modulated gasoline brought from the base into the aircraft's fuel tank, and then checked the lubricating oil and hydraulic oil. After confirming that there were no problems, he got on the aircraft and debugged it according to yesterday's steps.

After debugging is completed, slide the plane out of the berth, take a deep breath when you arrive at the take-off point, increase the throttle and let the plane rush forward.

When the speed reaches 160 kilometers per hour, gently pull the joystick towards your arms, and the plane will leave the water and fly into the sky.

This takeoff felt more natural than last time. He even had time to use his superpowers to record airflow data during takeoff. His hands were not as stiff during operation. After flying the plane yesterday, he felt his hands were a little cramped because he was too nervous and held the joystick too tightly.

As usual, it flew in circles around the test flight field, maintaining an altitude of about 300 meters. During the flight, it also observed the terrain below from time to time, preparing to find a place suitable for building a land airport.

Because subsonic aircraft can still use seaplanes, but supersonic aircraft are definitely not possible. A land airport with a length of 1500 meters and a width of 30 meters is enough.

After circling several times, he still couldn't find a suitable one because there were only hills and low mountains with trees on them and the terrain could not be seen clearly. So Wang Jiankun temporarily put aside the search for a site and waited until he became more proficient in flying the plane. He would fly at a low altitude of about 50 meters and use his superpowers to scan the terrain below.

About half an hour later, Wang Jiankun flew the plane to an altitude of about 800 meters and a speed of 400 kilometers per hour, then unfastened the buckles that fixed the model plane as planned.

The model plane was towed by a rope and flew about 1 meters behind the CJ-80.

The choice of this distance is very important, because after 50 meters, the airflow disturbed by the passing of the CJ-1 will become smoother. In order to eliminate the airflow interference caused by the aircraft flying in front, we deliberately chose to test it 80 meters behind it.

Wang Jiankun's super power projection range is now 130 meters, and there is no problem with the gas flow at 80 meters.

In order to conduct a comprehensive test, Wang Jiankun took the model aircraft to perform stretching, diving, turning, tilting and other movements, and recorded all the flight data one by one. Then, when it was time to descend, Wang Jiankun used his superpowers to disassemble the model aircraft to avoid affecting the CJ-1 during landing.

After the descent was completed, Wang Jiankun went to the speedboat to rest, drank some water and ate some dried meat he brought to replenish his energy, and then continued his flight training.

We took off and landed a total of four times this afternoon. Our movements became more skillful each time, and the take-off distance was shortened a lot. We could pull up the nose of the plane and take off at one-third of the way along this straight river channel. This was far from the first time when we had to pull up and take off almost to the end.

After returning to the underground base that night, Wang Jiankun gave the day's test data to Zhizi as usual and asked him to correct the design flaws.

Tuesday to Thursday afternoons were all a repeat of Monday's routine, practicing takeoff and landing, and testing the new aircraft designed by Tomoko.

On Thursday night, Chieko said that the model was already the best solution it could simulate and calculate. There was no need to fly the model anymore. If they wanted to get more data, they would have to build a real machine and test it.

Wang Jiankun recalled the flight conditions in the past few days, and he had flown for nearly 20 hours in total, so he decided to manufacture this subsonic seaplane tomorrow, Friday afternoon, and then conduct some water taxiing tests depending on the time. In order to manufacture this subsonic aircraft, Wang Jiankun specially manufactured 1 ton of aviation kerosene on Thursday night, and then prepared several kinds of metals, which were transported to the speedboat by motorcycle and trailer, because the engine of this aircraft was copied from the Greyhound transport aircraft on the US aircraft carrier, so aviation kerosene was required.

It is a turboprop engine that can provide 4800 shaft horsepower, but Wang Jiankun improved the propeller that comes with it instead of copying the Greyhound transport aircraft's propeller so that it can fit on the seaplane's fuselage.

On Friday afternoon, Wang Jiankun brought the prepared materials to the seaplane test flight site and dug a cave beside the river. During the excavation, he kept some elements to be used to build a new aircraft later.

The full-size data of the new aircraft is 15.2 meters long, 13 meters wingspan, swept wings, 6 meters high, wing area 4.8 square meters, empty weight 58 tons, load capacity 12 tons, available load capacity 15 tons, maximum take-off weight 8 tons, and it is powered by two T22-A-56 turboprop engines.

According to the performance calculated by Zhizi simulation, its maximum speed can reach 960 kilometers per hour, cruising speed is 900 kilometers per hour, stall speed is 180 kilometers per hour, range is 2800 kilometers, practical ceiling is 12000 meters, climb rate is 24 meters per second, and wing load is 380 kilograms per square meter.

After the excavation of the cave was completed, some auxiliary facilities were also built inside, such as boarding equipment, refueling equipment, lighting equipment (powered by solar panels and energy storage systems), ventilation equipment, etc.

After all these were completed, Wang Jiankun began to manufacture this large seaplane.

The first thing is of course the two huge floats, which can be retracted into the belly of the aircraft, which is equivalent to retractable tires. This is one of the reasons why this aircraft can fly so fast and so high. Otherwise, with two large floats, the resistance will be particularly large.

After the floats are manufactured, the skeleton will be manufactured first, followed by two turbine engines, then the corresponding internal pipelines, and various instruments. The aircraft will be equipped with radar and the US military's Transit satellite navigation and positioning system.

The instructions and documents for this positioning system were found in the U.S. military's data room in Okinawa. The actual system was also seen on aircraft carriers and destroyers, so Wang Jiankun built a receiver and tested it. Its positioning accuracy is 20 to 50 meters, which is barely acceptable. At least it is enough for the subsequent test flights of this aircraft and subsequent supersonic aircraft.

After all the internal parts were manufactured, Wang Jiankun checked the drawings as usual to make sure nothing was missing and checked the dimensions to ensure there were no errors.

After the inspection is completed, the outermost skin and some external parts, such as the pitot tube, are laid. This time, the skin is based on the US A-7 fighter. It is the easiest to use what is available. After all, things that are used on a large scale by the US military should be more reliable.

It was already past 4 p.m. when all these were completed. Looking at the sky, the sun was already setting, so Wang Jiankun quickly added lubricating oil, hydraulic oil and aviation kerosene.

While the sky was still relatively bright, Wang Jiankun launched the aircraft, which he named Y-1, the first subsonic model.

Sitting in the spacious and tall cockpit, Wang Jiankun felt great. The view was very good. After all, he was almost 5 meters above the water surface. When he glided the plane out of the cave, the sound startled the weary birds returning to the forest in the distance.

Fortunately, there are few people living within 10 kilometers of this area, otherwise it would be difficult to deal with. Such a large aircraft can still be seen clearly at about a kilometer.

As it was getting late, Wang Jiankun checked the instruments and the wings and tail near the berth to see if they were functioning properly. He then glided back and forth several times on the 3-kilometer river channel to get familiar with the operation of the aircraft. After all, he had only trained for a few hours on the flight simulator, so he had to familiarize himself with it more.

When the sun went down and the river surface was no longer clear, Wang Jiankun parked the plane back in the cave hangar, lowered a camouflage net at the cave entrance, and then drove the speedboat back to the temporary dock.

On the way, I was thinking that in the future I would mainly test-fly this aircraft at night. It is still too conspicuous during the day. The size of this aircraft is 1 or 5 times that of the previous CJ-6. It will definitely be easily discovered if it often flies during the day. But if it takes off and lands at night, indicator lights must be installed on the river surface and the top of the mountain. Otherwise, it will be pitch dark at night and I don’t have the ability to take off and land under such conditions.

So I decided to install lighting on the mountains and the river on both sides tomorrow. The test flight of this Y-1 will have to wait for a few days. I will use the CJ-1 to fly a few night takeoffs and landings to get familiar with the takeoffs and landings at night according to the indicator lights. At the same time.

After returning, Wang Jiankun first contacted his uncle and asked him whether the goods had been cleared through customs to Hong Kong. He felt relieved after receiving a positive reply. Once this batch of goods arrived at his uncle's place, it would at least greatly enhance the strength of the Nanjie Formation.

So he sent a message to his uncle and asked him how the pilot selection was going and how the basic flight training was going. His uncle did not reply that evening. Wang Jiankun knew that he was very busy recently, so he went to practice YI flying on the simulator by himself.

On Saturday afternoon, Wang Jiankun transported another batch of aviation kerosene, all of which were modified from purchased diesel. This is much easier than directly synthesizing it from hydrocarbon elements.

After arriving at the aircraft berth, Wang Jiankun first used his superpowers to climb to the top of the mountain on the left side of the river, and then built a 500KW solar power generation array on it, configured a 1MW lead-acid energy storage system, and also manufactured the corresponding wires and substation equipment.

After the energy problem was solved, a lighting lamp was installed every 30 meters on the top and middle of the mountain. Because the current LED brightness is too low, Wang Jiankun made the halogen lamp used in cars, which has a brightness and illumination distance several times that of ordinary incandescent lamps and fluorescent lamps.

The top of the mountain and the river surface on the right have the same configuration. After the facilities on the top of the mountain and the mountainside are installed and debugged, the next steps are the sides and middle of the river surface.

The Le'an River will flood in two months, so it is not advisable to manufacture lighting equipment on the riverside and at the bottom of the river. However, Wang Jiankun does not plan to use it for long. After testing the Y-1, he will have to find a place to build a land airport, and the CJ-1 can be flown here.

Wang Jiankun set up red light strips in the shallow waters on both sides, and a red halogen lamp was installed every 3 meters along the entire 20-kilometer-long riverbed.

Because the middle part of this section of the river is quite deep, more than 4 meters, Wang Jiankun led a straight pipeline from the bottom of the river, which is only 2 meters from the water surface. He then installed green halogen lamps on the pipeline, one every 15 meters.

In this way, when you look down from the sky during landing, you can see yellow warning lights on the top and middle of the mountain, followed by the width lights on both sides of the river and the green calibration light in the center. When the time comes, you can point the nose of the plane towards the green indicator light in the middle and there will be no risk of crashing into the mountain.

After the manufacturing was completed that afternoon, Wang Jiankun flew the CJ-1 twice in the evening. Because the aircraft was relatively small, he landed smoothly according to the light instructions.

In the past two nights, Wang Jiankun also flew the Y-10 for about 1 hours on the flight simulator. The terrain was made according to this section of the river and the mountains. He practiced takeoff and landing thousands of times, and he is already confident that he can fly the actual aircraft.

So on Sunday morning, Wang Jiankun went to the market at the Dongmen Bridge to have a nice breakfast, and packed 10 big meat buns to take to the water airport, intending to stay there for a few days and not come back.

After arriving at the water airport, Wang Jiankun conducted a routine inspection of the CJ-1, then flew it into the sky to patrol the test flight field to ensure that no one came to this area. He then lowered the flight altitude to about 50 meters and projected the terrain of about 100 square kilometers into his mind, and then analyzed whether there was a place suitable for building an airport.

The sky was overcast for several days, and the cloud height was about 1500 meters, so Wang Jiankun painted the Y-1 the same gray color as the clouds, so that even if someone looked up, they would not be able to see his plane clearly.

The paint job was done and Wang Jiankun lost no time in starting the Y-1, completing the pre-takeoff check and heading for the take-off point.

Sitting in the cockpit with an excellent view, looking at the straight water runway in front of him, Wang Jiankun was quite excited, as he was about to fly this huge aircraft into the sky.

Following the thousands of training steps he had performed on the flight simulator, he turned some switches on and off, and used his superpowers to check the fuselage one last time. Finding no flight abnormalities, he stepped on the throttle and the plane quickly moved forward. When the speed reached 260 kilometers per hour, Wang Jiankun pulled the joystick toward him, quickly lifted the nose of the plane, and the plane left the water and rushed into the sky.

At this time, it is about 1 kilometer away from the end of the runway, which is still relatively safe. Once you become more familiar with it, the take-off distance can be shortened further.

This is all I have to post for now. I wanted to post some other plots together in this chapter, but the kids are too noisy, so I will post the sequel tomorrow morning.
