In 1999, many people were focusing on the core areas of the city and trying their best to acquire land for development.

Donghua teamed up with its partners to open up a battlefield in the west, acquiring thousands or tens of thousands of acres of land, and embarked on projects worth hundreds of millions or more than a billion.

These are real industries, and they are more concerned by senior officials.

The horn of western development has sounded, and various departments in Donghua have become nervous.

Besides Donghua Construction, the one with the heaviest task is Donghua Heavy Industry.

Chen Lichun received a task and got a headache. Different types of furnaces: gas-based iron oxide reduction furnace, ultra-high-power electric arc furnace, crucible furnace for melting basalt, quartz furnace for refining single crystal silicon, calcining furnace of cement plant...

...

Various types of steel rolling machinery, ingot casting machinery, stamping machinery, extrusion machinery...

Powerful mining equipment: several specifications of mine cars, tunnel traction equipment, rock drilling equipment, shovel equipment...

Now we need to modify the heavy truck.

Although Mary is in charge of the car business, she is only responsible for design, planning, marketing, production and modification. Chen Lichun is still responsible for this part.

Chen Lidong has already expressed his opinion on Donghua Heavy Industry's production model: We don't want to do everything. From now on, what we need to do is develop technology, formulate standards, issue orders, and complete the assembly.

We must learn to select suppliers from across the country and around the world, and establish our own supplier system and team...

The first two are bigger and there is Li Taishun.

He accepted a large number of research and development tasks assigned by Chen Lidong, most of which were electromechanical, including the transformation of various construction machinery such as pure electric excavators, loaders, road rollers, pavers, cranes, dynamic compactors, and pile drivers.

The templates for the modification design are similar, which is to install a super battery on the original chassis, make the power system pure electric, and optimize the control system.

These are not complicated. All you need to do is distribute the tasks, and Li Taishun will be responsible for taking the lead, controlling the progress, and providing technical guidance.

He is currently working on an all-in-one solar panel automatic dust removal, snow removal and cleaning machine.

If solar panels cannot be cleaned in a timely and effective manner, their power generation efficiency will be greatly reduced, which will cause huge economic losses to photovoltaic power generation companies.

A high-pressure cleaning machine has been developed before, which is just a water gun. It is not efficient, wastes water, and can easily damage solar panels.

Chen Lidong asked the R&D department to develop a cleaning equipment that integrates snow removal, dust removal and cleaning.

Li Taishun has developed a manual hand-held cleaning and dust removal equipment. It is a long pole with a motor installed in front. The motor rotates to drive the brush to work, and the dust removal effect is good.

The long pole is hollow, with a water pipe installed inside and connected to a water tank. After adding pressure, water will spray out from the small holes in the brush wheel, and the surface of the battery panel can be cleaned.

If you want to remove snow, you should be able to use this brush wheel.

In short, it is much more high-end than the original water gun.

But Chen Lidong was not satisfied. He suggested that Li Taishun develop an all-weather, fully automatic automatic cleaning machine.

Li Taishun has now developed a dust removal and cleaning equipment with a relatively high degree of automation. The main body is a spray device across the panel, which is installed on the frame of the photovoltaic module. After starting, it automatically moves from one side to the other along the guide rail.

Wash the board like a car.

It was rejected after it was created.

If this solution is adopted, each group of photovoltaic modules will need to be equipped with a set of such cleaning devices, which is too wasteful and might as well be a hand-held mop.

Chen Lidong agreed to produce a batch of electric mops first, but he still wanted to get higher-end ones.

After making gestures and drawings, Li Taishun finally understood.

I dare Chen Xiaoer to want to make a flying cleaning robot, or install an electric brush on a drone.

Unmanned aircraft have been around for a long time. In 1991, multinational forces used unmanned aerial vehicles during desert operations in the Persian Gulf.

The most powerful ones are Sam’s “Curly Hound” and “Death Bee” drones.

The Hound series of UAVs were developed by Northrop Grumman Corporation of Sam Country. Its main functions are reconnaissance and surveying, and it can also be equipped with missiles. This type of UAV is launched through the guide rail by ejection, and the power is to install

Propeller at waist.

The Curly is a pocket-sized propeller aircraft, a medium-sized drone among drones, with a body length and wingspan of nearly 3 meters.

The "Death Bee" UAV was developed by the Johns Hopkins University Applied Physics Laboratory and produced by Bai Aerospace Systems. It has a propeller on the head, an engine in the middle of the body, a delta-wing body, GPS positioning, and infrared

camera.

The Death Bee can be considered a small drone, with a length of about 1.62 meters, a wingspan of 2.5 meters, and a weight of only 41 kilograms.

In short, these drones all use fuel engines and are relatively large.

The drone Chen Lidong is talking about should be classified as micro. He said: "The drone is about the same size as a computer. It uses a micro motor to drive four propellers and can fly straight and land. It can be used for aerial photography and cleaning operations."

Li Taishun thought for a while and asked: "The solar panel is on a slope, how can the helicopter land?"

Chen Lidong became speechless upon hearing this. He said, "It's up to you." Then he ran away.

Li Taishun watched Chen Lidong walk away, and then fell into deep thought.

He knew that many of Donghua Technology's ideas came from this boss's head.

The drone just discussed should be possible, but the key is battery technology.

If the battery energy density is upgraded and the materials are lighter, you can play with it.

After thinking for a while, Li Taishun took out his cell phone and called his wife.

Sun Lan was on a business trip at this time, and her main task was to sign a package of scientific research agreements with Northwestern Polytechnical University. Donghua Technology would fund the project and support NPU in establishing a specialized laboratory to carry out key project research.

These laboratories include the Micro Motor and Drive Technology Laboratory in collaboration with the Institute of Automation; the Micro Satellite Engineering Laboratory in collaboration with the Institute of Aeronautics; the Combustion, Thermal Structure and Internal Flow Field Laboratory, and the Industrial Engineering and Intelligent Manufacturing Laboratory in collaboration with the School of Materials.

.

The method of cooperation is that NPU provides the site and personnel, and Donghua Technology provides the equipment and materials, and together they apply for scientific research funding from the state. If the funds are insufficient, Donghua Technology will provide support based on the actual situation of the project.

At the same time, Sun Lan also brought a scholarship to provide relief to students with poor families and excellent academic performance.

The leaders of NPU attach great importance to Donghua's arrival.

Sun Lan came here in the name of "supporting Chinese education and promoting scientific and technological progress", but to put it bluntly, she was just giving out red envelopes.

If the price of the list of equipment and materials submitted by those laboratories is calculated, the total amount exceeds 100 million.

I chose NPU because of the relationship between the principal and Mr. An, and because of Chen Lidong’s approval.

Nowadays, the enrollment situation of NPU is good, but the infrastructure is relatively backward. The school leaders are more interested in capital to directly support a fund to improve school conditions.

So Sun Lan enjoyed very high courtesy.

After answering her lover's call, Sun Lan asked Liu Yuhua, assistant to the principal, who accompanied her to visit Huaqing Palace: "Is there anyone in NPU who makes drones?"

Liu Yuhua quickly said: "Yes, yes. We have a UAV Technology Research Institute. The first UAV in China was built by our school. Do you want to..."

Sun Lan asked: "Can I visit it?"

Liu Yuhua hesitated for a moment and whispered: "This research institute is for research and development for the army, and there are confidentiality requirements."

Sun Lan said: "Then forget it."

However, the next day, Wu Xiaobing, the chief engineer of the UAV Institute, and his wife rushed over and asked to see Sun Lan.

Wu Xiaobing has been in a lot of trouble recently. Just last month, a key project for pre-research for the army failed. The so-called failure was that the trial drone fell down on its first flight.

The source of the problem is also clear: the fuselage material is too heavy and the engine power is insufficient.

The engine is a fuel engine developed and produced by the UAV Institute of NPU, which represents the highest level of the "heart" of China's small and medium-sized UAVs.

But Wu Xiaobing knew that compared with internationally mature engines, it was at least 20 years behind.

After the first flight failed, he asked for approval from the institute and used the only imported engine. After installing it, the test flight was successful.

But just a few days ago, the institute contacted the seller to purchase a batch of engines, but the other party reluctantly said: Due to problems with the Serbian and Montenegrin embassy, ​​the export qualification of this model of engine to China has just been cancelled.

Wu Xiaobing was anxious. The first flight was successful. The army had approved this drone and was preparing to purchase a batch for equipment testing.

Engine purchase is limited! Isn’t this being put on a rack and grilled?

Wu Xiaobing originally didn't want to use imported engines, but when he got to this point, how could he explain it to the troops?

When he was suffering, his wife told him in the evening: "Liu Yuhua said that Manager Sun Lan of Donghua Technology had asked about the drone. Due to confidentiality reasons, he could not come to visit. I wonder if Donghua can get the engine.

”.

Wu Xiaobing perked up and said, "Even if you can't get it, you still have to ask. I'm at the end of my rope. I'll pay a visit to Mr. Sun tomorrow."

"I'll go with you too."

When they got up in the morning, Liu Yuhua took Wu Xiaobing and Dong Jing to meet Sun Lan.

A few people had breakfast together first, and Sun Lan began to think that this was Liu Yuhua's special arrangement.

Unexpectedly, Wu Xiaobing asked Donghua for help.

After eating and wiping his mouth, Wu Xiaobing said: "Mr. Sun, I'm here to cause trouble for you."

Sun Lan asked: "General Master Wu is very polite. If you need anything, just ask. I will try my best to do what I can."

Wu Xiaobing expressed his dilemma: "This is probably the situation. We are stuck by foreign parties."

Sun Lan comforted and said: "Don't worry, I'll ask the company first if they can think of a way. Maybe one of our units has such spare parts in stock. Oh, what type of engine do you need?"

Wu Xiaobing said: "It's Osteia's rotax914f piston engine."
