Black technology: I can decompose everything

Chapter 103 Prepared (35)

The two test pilots listened very seriously at first, but as Li Zhenhua spoke in more and more detail, they also understood how the rotorcraft operates.

For two test pilots with extremely rich flying experience, the operation of this simple aircraft is really not difficult.

After Li Zhenhua told them how to operate, he returned to Professor Du's side. Seeing him come back, many ground crews here became busy.

The two engineering students who came with them also got busy with the ground staff, filling up the gyroplane with 98 gasoline and making various preparations.

After all this was done, one of the test pilots boarded one of the military version of the rotorcraft, and after receiving the take-off order, the test pilot started the engine.

Driven by the engine, the thrust propeller generates power, pushing the rotorcraft to slowly drive to the runway.

As the engine throttle increased, the rotorcraft began to roll on the runway. As the speed of the rotorcraft's taxiing became faster and faster, the propeller above the head also began to rotate against the wind.

The glide distance of the rotorcraft is not very long, it is only more than 30 meters, and the lift generated by the propeller above the head is enough for the rotorcraft to lift into the air.

After continuing to run forward for more than ten meters, the three wheels of the gyroplane had left the ground, and it was at this time that the gyroplane was gently lifted up under the control of the test pilot.

As the test pilot pulled the joystick back, the windward angle of the propeller above his head also changed, and then the gyroplane completely left the ground.

Soon the rotorcraft began to fly over the airport, flying sometimes fast, sometimes slow, sometimes high, sometimes low.

After the experienced test pilots were familiar with the control of the rotorcraft, they began to follow the orders from the ground and started the various tests of the rotorcraft in a targeted manner.

Since the gyroplane went up, it has been flying from two o'clock to six o'clock, and it was getting dark, so it started to enter the landing procedure due to insufficient fuel.

As long as they pass the last test, their test flight today will be considered a real success.

Li Zhenhua spent the whole afternoon looking up at the rotorcraft flying in the sky, but as the flight time got longer and longer, he was not worried about any problems with the rotorcraft at all.

"Ground tower, the bird is calling, apply to enter the unpowered gliding landing test!"

"The control tower has received it, and agrees that the bird will enter the next test subject!"

Listening to the communication between the test pilot and the control tower, Li Zhenhua moved his stiff neck, raised his head again, and stared at the rotorcraft in the sky.

"The bird successfully extinguished the engine, and the gyroplane entered the gliding and landing stage!"

The voice of the test pilot came out from the side speaker. Under Li Zhenhua's gaze, the power propeller behind the buttocks of the gyroplane flying in the sky stopped rotating at this moment.

However, the propeller on the top of the gyroplane rotated as before, providing lift for the gyroplane.

After the gyroplane loses power, its flight altitude is decreasing, and its flight speed is also slowing down.

Under the control of the test pilot, the gyroplane circled over the airport for many times before lowering the altitude to a height where it could land.

The nose of the gyroplane changed slightly, the gyroplane was aligned with the runway, and the altitude was continuously dropping, and soon the three wheels of the gyroplane landed on the runway.

The landing process was very smooth, without even a single mistake, and the gyroplane taxied on the runway for more than ten meters before stopping.

When the gyroplane landed successfully, when the propeller stopped turning, and when the test pilot jumped off the gyroplane, there was warm applause at the scene.

This applause is not only to celebrate the successful test flight of the rotorcraft, but also to the test pilots.

The test flight was successful, and Li Zhenhua and the others also obtained all the flight data of the rotorcraft during this test flight.

The first is the speed of the rotorcraft, which can easily reach 185 kilometers, and can also cruise at this speed. As for the fastest speed, it can reach 237 kilometers per hour.

The airborne time of the gyroplane, calculated according to the remaining fuel on the current fuel gauge, can probably fly in the sky for no less than five hours.

Calculated in this way, the cruising range of a fully fueled rotorcraft can reach an astonishing 900 kilometers.

The maximum ceiling of the gyroplane was also tested in this test flight. The gyroplane can fly up to 6000 meters in the air, the minimum flying height is 0.5 meters, and it can also achieve hovering.

A flying speed that can be flexibly changed between hovering to 235 kilometers, and a flying altitude span between 0.5 meters and 6000 meters. The performance of such a rotorcraft is almost unremarkable.

Moreover, the cost of using this small plane is also extremely low, not much higher than using a car, it is nothing more than the fuel mark is higher.

And after getting all these test data, Li Zhenhua himself really understood why such a simple small plane can be equipped by the army.

How about a small aircraft capable of penetrating defenses at low altitudes, not too slow, not too loud, with a crew of about three, and a load of 800 kg? Doesn’t it meet the needs of the army?

Moreover, in Li Zhenhua's opinion, the most suitable scene for this small aircraft is not other places, but to be equipped with border guards and let them fly this small aircraft for daily border patrols.

However, these things have nothing to do with the current Li Zhenhua. He has already approached the test pilot and asked him about his flying experience. He is too curious about the small plane he created.

"May I ask how the flying experience of this gyroplane is? Is there anything wrong with you, can you tell me about it?"

Li Zhenhua couldn't wait to ask. Faced with his question, the test pilot explained his experience of using it to them.

Even if the test flight on this day came to an end, all the test flights were not completed, and the test flight would continue on the next day. According to the news Li Zhenhua got from Professor Du, as long as he hadn't participated in the exhibition, the test flight would continue.

On the second day, the test flight continued, but compared to yesterday's test flight, today's scale is larger, because yesterday only one rotorcraft was flying in the sky, but today all six were sent to the sky. .

Two-seater, three-seater, open, closed, military, civilian, anyway, each of the six rotorcraft has its own test items.

The test flight lasted until the night of NO.17, and the test flight was not completed until now. It wasn't that they didn't want to test more detailed data, but that they didn't have enough time.

Because they will be NO.18 the next day, and the internal exhibition of NO.19 will start, and they will rush to the venue tomorrow to make arrangements in advance.

　Had a hard time coding today, my son doesn't go to school, he's so fussy, so this chapter has dragged on until now.

　　There are two more updates today, and they must be completed before twelve o'clock, so stay tuned!
