Since Li Guocheng wanted to engage in motorcycles and cars, he revised Xiao Er's task and asked him to help summarize and analyze the data, because it is difficult for him to have a large period of time to study quietly.

While waiting for the actual motorcycles and cars, Li Guocheng designed the shape and structure of several motorcycles.

As a motorcycle enthusiast, Li Guocheng also collected several motorcycles in his later life, but he only played with them and did not have an in-depth understanding. But all sorts of cool looks are already in my mind.

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

What he's doing now is to design a few cool shapes first, specifically for the core engine, and then he can only refer to the prototype.

Relying on his and Xiao Er's derivation ability, they may be able to design a better engine.

He first carved out more than a dozen models with a carving knife, relying on profound aesthetic cultivation, these models are a bit domineering when viewed from the outside, some have beautiful lines, an ultra-low center of gravity, front suspension, and rear suspension.

No matter what the model, the ergonomic aesthetics are fully considered.

Xiao Er scans all the models, first makes local modifications to the models according to the specific wind resistance and mechanical strength requirements, and then considers the manufacturability and decomposes them into independent modules.

The commonality of the modules is considered for each vehicle model.

In order to ensure computing power, Li Guocheng remanufactured four sets of Kunpeng 2000 servers. Now there are a total of 8 sets of servers, 2 groups are occupied by Primary 3, and 3 groups are occupied by Primary 1 and Primary 2 respectively.

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

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

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

The car is temporarily parked in the parking lot with only two models: KE70 and Single-Cab. Wait until later to disassemble.

To keep it covered, all motorcycles are transported to the underground parking lot by vans. Then in the second half of the night, it was transported by elevator to Li Guocheng's personal comprehensive laboratory.

On the second day, starting each motorcycle and controlling the throttle, Li Guocheng understood the working principle and control process of the engine through telekinesis, and had a subtle understanding of the valve and oil circuit control in the process of air intake, compression, combustion and discharge.

At the same time, the focus is on the heat dissipation mechanism of several engines.

Next, the exterior is scanned, then the parts are scanned as they are disassembled, and then 3D modeling is performed on the Kunpeng 2000 server.

Three days later, all the scanning and modeling work was completed, and Li Guocheng and Xiao Er worked together to disassemble and combine several engines, learn 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 the LH125 and features:

1. Single-cylinder four-stroke engine with air-cooled heat dissipation system, with a maximum power of 8.2 kW@8,000 rpm and a maximum torque of 12.2 Nm@6,500 rpm.

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

3. High efficiency and low fuel consumption: The engine adopts advanced intake and exhaust systems, which effectively improves the fuel economy and emission performance of the engine. The fuel economy of the engine is excellent, and it can be kept economical and environmentally friendly.

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

The sporty model is defined as the LH250 and features:

1. The maximum output is 55 horsepower (/9,500 rpm) and the peak torque is 34 Nm at 8,000 rpm, which can give the driver a strong driving experience.

2. Double-cylinder design: The V-shaped double-cylinder structure is adopted, which makes the vehicle have a very good power output and stability. The twin cylinders are lightweight, stable and reliable, which greatly improves the power and durability of the engine.

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

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

5. Liquid cooling system: make the engine always stay in the best working temperature range during operation, and make 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 boosters, aluminum alloy reciprocating air radiators, electronic fuel injection technology, etc. These technologies allow the engine to perform better.

7. The microcontroller adopts a newly designed KT32F202M, which is used for the leg control of Xiao Er.

After more than 2 months of repeated deliberation and repeated simulations, even Li Guocheng was very tired, and ordered Xiao Yi and Xiao Er to enter the 'room' and connect Kunpeng to continue working, and 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 the customs, and I happen to be looking for you for something."

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

"Hehe, don't rush home, the Z-7 prototype has completed its design and is about to be transported to the ** aviation base to carry out wind tunnel experiments. Everyone is not at ease, and in the end, I want you to check it."

Hearing this good news, Li Guocheng immediately stopped sleepy.

"Let's go, let's see".

The installation workshop of the Z 7 was built improvised on a basketball court, which resembles a warehouse.

Entering the workshop, several professors were there, and everyone else was waiting for Li Guocheng's arrival.

"Li Dong, look, straight 7 beautiful!" It was Professor Ma, an expert in aerodynamics who came to support later, who spoke.

Can it be pretty, the Z-7 is optimized on the basis of Apache, the whole shape is much fatter than Apache, and it is a new model that integrates transportation, air-to-air, and ground strikes.

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

The biggest improvement is in the flight control system.

Two redundant 15-inch self-heating LCD screens reduce 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 know the status of the aircraft in time.

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

Excellent auxiliary control system assists the pilot to fly the aircraft, and any operation of the pilot will be assisted and optimized to avoid helicopter damage caused by wrong operation.

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