Synthesis of everything starting from models

Chapter 42 Model aircraft?Fixed-wing propeller drone!

The assembled body parts were put aside by Li Anchor, while he assembled the power system himself.

Whether it is a model aircraft or a real propeller aircraft, there is actually no gearbox on it, so how to change the speed?Controlled by the throttle of course.

So to a certain extent, the structure of a propeller aircraft is simpler than that of a car.

Li Anchor used a forklift to hoist the mini engine according to his own design, and pushed the assembled body over. Then the other unassembled bodies were put in place along with the engine, and they were all assembled together.

The engine was installed into the body, and Li Ao began to organize various control circuits inside the body and connected the circuits to the engine.

After connecting the control system to the engine, connecting the oil line to the wing fuel tank, and installing two 12v lead-acid batteries in the body, everything inside the body was completed.

Now only the propeller is left, and the wheels of the landing gear have not been installed in place. The propeller has been printed together before, but the wheels are a bit difficult.

After all, his printer has not printed rubber materials yet, and he has not prepared rubber materials. Even if the printer can print, there is no material.

As for where to buy the tires, that still has to wait, but Li Ao has nothing to do. Although solid rubber tires are not available for the time being, he can still use the tires of small-wheel electric vehicles to push them on for a while.

The tire problem had been solved, and Li Anchor then began to assemble the propeller of the aircraft model.

At this point, the aircraft is considered complete, with its entire body showing a metallic luster and shining brightly.

The plane in front of him had a total length of 1.26 meters, a wingspan of 1.87 meters, and a total height of 0.53 meters.

It is completely scaled down according to the ratio of 1:10, based on the Y-5 prototype. Of course, there are still differences. The original upper and lower double-layer wings have been optimized by him into a high-monoplane wing.

Li Anchor went up to the plane and tried to weigh the plane while holding it. He felt that the total weight should be about 30 kilograms. As for the take-off weight, it will be determined through later tests.

Looking at the more than one meter long model aircraft in front of him, Li Ao said it was impossible not to be excited. Moreover, the body of this model aircraft was made of all metal, which was completely different from what he had played with before.

It's not that he has never played with aircraft with a wingspan of more than 1.5 meters before, but those aircraft bodies are almost all made of foam. Although the foam is very light and strong, it is completely incomparable to a solid metal body.

At this moment, Li Ao wanted to fly this thing into the sky immediately, but unfortunately, the current conditions were not sufficient. At least the wheels of the landing gear were not ready yet, and there was no fuel.

The 10L of gasoline I bought earlier had been burned out by the mini engine. Apart from these, Li Ao actually had another idea, which was to install a set of motion sensing lenses on this model aircraft.

With the somatosensory lens and VR glasses, you can create a very simple and realistic model airplane, and then you can really experience the fun of flying.

At this time, Li Ao was already having fun. As for the cost, that was not what he was considering at the moment.

With the idea in mind, Li Ao immediately took action, packed up everything in the workshop, got in his car and left the factory.

The car left without a sound. Li Anchor first went to a place that sold electric cars, bought three sets of the smallest tires, and then drove straight towards home.The car was parked downstairs in his house. He went upstairs in a few steps, picked up a DJI gimbal and a camera he didn't often use, and ran back to his bedroom, holding the VR glasses he often used to watch Mikami in his arms. .

Taking a few things, he went downstairs, drove to the car, and bought some second-hand mobile phones from a second-hand mobile phone store near his home. After finishing these things, Li Ao drove back to the delivery room.

As soon as Li Anchor came back, he came to the office with a bunch of messy things.

After taking a deep breath and calming down, he started to dismantle and disassemble. He kept welding with a soldering iron, and then glued and glued again. Finally, Li Anchor was still uneasy and tied several ties. bring.

At this time, the handle below the gimbal has been removed, a Canon 500D camera has been connected to the gimbal, and next to the gimbal, there is a second-hand mobile phone that has just been welded together.

On the other side of the platform, there is a very old VR head-mounted glasses. At this moment, the VR glasses have long been unrecognizable, and they are covered with various flying wires.

By now Li Ao had been working on it, the time had quietly come to the afternoon, but when he had an idea, he didn't feel hungry at all, but only felt a full sense of accomplishment and excitement.

After finishing these things, Li Anchor drew a mounting bracket inside the aircraft model on the computer and distributed it to the laser sintering printer.

Taking advantage of the gap in printing the bracket, I installed the three small-sized pneumatic tires I just bought on the model aircraft. Although they are not solid tires, I will use them first anyway!
He had just installed the tires, and then the bracket was printed. Li Anchor took off the bracket again and fixed the gimbal camera with the somatosensory module firmly inside the model aircraft with the bracket.

What should be connected to the power supply, what should be fixed should be fixed, and then Li Anchor couldn't help but put the modified VR glasses on his head.

As the prompt that the glasses and the lens in the cabin were successfully connected appeared, the gimbal and the lens began to complete the self-check, and then the somatosensory gyroscope began to exert force, and the VR and lens completed the linkage.

I saw that if Li Ao turned his head to the left, the camera inside the machine would turn to the left under the action of the gimbal; if he turned his head to the right, the camera would turn to the right.

Anyway, no matter what actions Li Anchor makes, the camera inside the plane will make corresponding actions.

After some experiments on his part, his original idea was completely realized.

The ordinary four-channel remote control is used to control the system. The field of view is provided by the somatosensory linkage lens in the machine. The machine itself is powered by a fuel version.

The total length of the aircraft is more than one meter. What else is a model aircraft called?It's enough to just call it a fixed-wing propeller drone.

The powerful power of the mini engine, coupled with the nearly 10 hours of battery life of 40L of gasoline, directly gives the model aircraft the ability to stay in the air for a long time.

Although in actual use, the battery life will definitely not be that long, but even if it is halved or reduced by one-third, the airborne capability is still powerful enough.

The thing Li Ao has built now is really looking less and less like a model aircraft. It really looks like a fixed-wing propeller unmanned reconnaissance aircraft.

I just don’t know how this thing performs after it flies into the sky?
What's the speed?How long is the battery life?What is the maximum take-off weight and what is the maximum load capacity?
