Siheyuan: Starting from a fitter

Chapter 313 The birth of the Z-7 armed helicopter

Ever since Li Guocheng wanted to develop motorcycles and cars, he modified the waiter's tasks and asked him to help collect and analyze data, because now it is difficult for him to have a long period of time to concentrate on research.

While waiting for the actual motorcycles and cars, Li Guocheng designed the shapes and structures of several motorcycles.

As a motorcycle enthusiast, Li Guocheng also collected several types of motorcycles in his later generations, but he only played them for fun and did not understand them in depth.However, the various cool shapes have been deeply ingrained in my mind.

For example, Ninja H2R, Suzumoto Hayabusa, Yahaha VMAX, Kida NR750, Harley Prince and other products.

What he is doing now is to design several cool shapes first, as far as the core engine is concerned, and then he can only refer to the prototype.

Relying on his and Xiaoer's derivation abilities, it may be possible to design a better engine.

He first carved out more than a dozen models with a carving knife, relying on his profound aesthetic accomplishment. These models looked a bit domineering from the appearance alone, some had beautiful lines, ultra-low center of gravity, front suspension, and some rear suspension.

No matter what model, ergonomic aesthetics are fully considered.

The waiter scanned all the models, first made partial modifications to the models based on specific wind resistance and mechanical strength requirements, and then decomposed them into independent modules considering manufacturability.

The versatility of modules is also considered among various models.

In order to ensure computing power, Li Guocheng re-manufactured four sets of Kunpeng 4 servers.There are now a total of 2000 groups of servers, 8 groups are occupied by the third party, and 2 groups are occupied by the first and second servers respectively.

After arranging the work, Li Guocheng continued to study the parameters of various motorcycle engines.

Half a month passed quickly, and the four models that arrived first were Honda 125, Linmu GS125, Linmu GSX-400, and Linmu RG250.

The most incredible thing is that Wu Liankui actually got a beta version of Linmu RG250.

The cars are temporarily parked in the parking lot, and there are only two models: KE70 and Single-Cab.Wait until later for disassembly.

In order to conceal their identity, all motorcycles were transported to underground parking lots in box trucks.Then it was transported by elevator to Li Guocheng's personal comprehensive laboratory in the middle of the night.

On the second day, Li Guocheng started each type of motorcycle and controlled the throttle. Through his mind power, Li Guocheng understood the working principle and control process of the engine, and gained a detailed understanding of the valve and oil circuit control in the intake, compression, combustion, and exhaust processes.

At the same time, we focus on the heat dissipation mechanisms of several engines.

Next, first scan the appearance, then disassemble and scan each component, and then conduct 2000D modeling on the Kunpeng [-] server.

Three days later, all scanning and modeling work was completed. Li Guocheng and Xiaoer worked together to decompose and combine several engines, learn from their design experience, and analyze the characteristics of the materials.

Two months later, two engines were finalized, one lightweight and one sporty.

The lightweight model is defined as LH125, and its characteristics are:

1. The single-cylinder four-stroke engine adopts an air-cooled cooling system, with a maximum power of 8.2 kW@8 rpm and a maximum torque of 000 [email protected] rpm.

2. Simple and reliable: It adopts a simple and reliable mechanical structure without too many complicated electronic control systems and devices, so it has the advantages of simple structure and easy maintenance.Many engine parts are removable and relatively easy to manufacture and repair.

3. High efficiency and low fuel consumption: The engine adopts advanced air intake and exhaust systems, which effectively improves the engine's fuel economy and emission performance.The engine's fuel economy is excellent, keeping it both economical and environmentally friendly.

4. Lightweight and stable: The engine is made of lightweight materials and has high lightweight performance, ensuring the vehicle's flexibility and controllability.Moreover, the engine's mixed oil supply system and cooling system are reasonably designed, and its stable and reliable performance ensures good stability during operation.

The sporty model is defined as LH250 and its features are:

1. The maximum output power is 55 horsepower (/9 rpm, and the peak torque is 500Nm/34 rpm, which can give the driver a strong driving experience.

2. Twin-cylinder design: The V-shaped twin-cylinder structure is adopted, which enables the vehicle to have very good power output and stability.The twin-cylinder is characterized by being light, stable and reliable, which greatly improves the engine's power and durability.

3. Two-stroke technology: By sharing one combustion chamber with each two cylinders, it can provide greater power with the same displacement.In addition, for motorcycles with higher high-speed speed requirements, two-stroke engines can also provide greater output power and high torque performance.

4. Independent electronic ignition system: This system will continuously and accurately distribute fuel according to the requirements of engine speed and load, and adjust the ignition time to improve fuel utilization and improve engine reliability.

5. Liquid cooling system: It keeps the engine within the optimal operating temperature range during operation and makes the engine life more stable and reliable.

6. High-performance components: A number of innovative technologies are used, such as exhaust control valves, adjustable torque enhancers, aluminum alloy reciprocating air radiators, electronic fuel injection technology, etc.These technologies allow the engine to perform better.

7. The microcontroller adopts the newly designed KT32F202M. This microcontroller is used to control the waiter's legs.

After more than 2 months of repeated deliberations and simulations, even Li Guocheng was very tired and ordered the first and second waiters to enter the 'room' and connect Kunpeng to continue working. He had to go home to rest.

As soon as I walked out of the building, I met Representative Luo head-on.

"Lao Li, you are out of seclusion. I just want to see you if I have something to do."

"Tell me, I'm in a hurry to go home."

"Hey, don't go home in a hurry. The Z-7 prototype has been designed and is about to be shipped to the ** Aviation Base for wind tunnel experiments. Everyone is worried. Finally, I want you to check it."

After hearing the good news, Li Guocheng felt no sleepiness immediately.

"Go, have a look."

Zhi7's installation workshop was temporarily built on a basketball court and looks like a warehouse.

Entering the workshop, several professors were there, and others were gathered around waiting for Li Guocheng's arrival.

"Director Li, look at it, the straight 7 is beautiful!" The person who spoke was Professor Ma, an aerodynamics expert who came to support later.

Is it beautiful? The Z-7 is an optimization based on the Apache. The overall appearance is much fatter than the Apache. It is a new model that integrates transportation, air and ground attack.

Li Guocheng personally carried out industrial aesthetic design, which is beautiful, practical and has high space utilization.Advanced liquid cooling + air cooling heat dissipation technology extends the life of the engine.

The biggest improvement is the flight control system.

Two redundant 2-inch self-heating LCD screens save a lot of control buttons and indicator lights, and the operating status of the aircraft is displayed on the LCD screen in real time, which is convenient for pilots to keep abreast of the status of the aircraft.

The advanced adaptive stabilization system reduces the pilot's control difficulty.

The excellent auxiliary control system assists the pilot in flying the aircraft. Any operation performed by the pilot will be assisted and optimized to avoid damage to the helicopter caused by incorrect operations.

If an electronic pod is installed, it can better identify and track targets and carry out precise strikes.
