Start with a blacksmith shop

Of course no one heard Lieutenant Wang's exclamation, and even if they did, no one would refute him.

As for the muffler of this engine, it still uses the original muffler that came with the motorcycle.

They have also tried their own silencer systems, but they are not as thorough as the original ones.

This also proves from another aspect that the muffler created by Li Zhenhua is indeed awesome.

The noise produced by the rotation of the propeller masks the sound of the engine.

Lieutenant Wang closed the small window again and looked at the propeller rotating at a constant speed.

Propeller noise is also isolated from the aircraft cabin.

Then he gave the ground staff a thumbs up, and the ground staff received it.

At the temporary tower, Mr. Yan, as the chief engineer, also gave the order for the test flight.

Lieutenant Wang, who received the takeoff order through the headset, was also unambiguous.

Controlling the plane on the runway, it slowly began to accelerate.

When the plane reaches a certain speed, the two engines drive the propellers to rotate crazily.

The thrust generated by the propeller pushes the entire aircraft forward.

The nose landing gear of the plane also lifted off the ground under the influence of this thrust.

Lieutenant Wang felt the state of the aircraft and knew it was time to pull up.

Touch the throttle handle on the instrument panel with your right hand, push the handle to the front, and use the maximum throttle.

Seize the opportunity, hold the V-shaped operating lever tightly with both hands, and lift it up with slight force.

At full throttle, the nose of the aircraft leaves the ground.

This was because Lieutenant Wang was driving for the first time and was not familiar with it.

The movement of lifting the control stick was a bit too big, almost causing the tail of the aircraft that had not yet left the ground to touch the runway.

That is to say, Lieutenant Wang had rich experience and corrected the attitude of the aircraft in time and loosened the control stick, so that the accident was not caused.

The plane was completely off the ground, and with space, Lieutenant Wang also had a place to do whatever he wanted.

The full throttle state was not released just now, but the joystick was pulled up hard.

The plane also followed Lieutenant Wang's driving and made corresponding movements.

At this moment, I saw that the plane was climbing at a large angle of forty degrees with the ground, climbing towards the blue sky.

When the plane climbed to 2,000 meters and was about to enter a stall, Lieutenant Wang changed the plane to level flight.

After the change, my right hand was freed up and the throttle valve was withdrawn from the full throttle state.

The speed of the aircraft was maintained at 240 kilometers per hour, and it flew at an altitude of 2,000 meters for several minutes.

"Tower, tower, please climb to three thousand meters to continue testing."

Lieutenant Wang seemed to be fine, flying freely in the sky.

But it was a completely different mentality on the ground. Everyone on the ground was so frightened by the scene that they just took off that they broke into a cold sweat.

"Old Zhou, look, did you fail to say something just now?"

Mr. Yan turned to Mr. Zhou, who was holding a telescope and shaking his head following the plane and asked.

"Ah, what did you say?"

"I said that I thought that Mr. Wang was treating our little toy as a fighter jet.

Didn't you tell him that this is a civil aviation aircraft, not a fighter jet? "

After hearing Mr. Yan's question, Mr. Zhou suddenly slapped his forehead and said.

"Oh, I really forgot. It's my fault. I've never done anything civilian before.

I thought it was a fighter jet, so I didn't notice it and didn't give any instructions. "

Several staff members nearby listened to the conversation between the two and smiled, as if it was true.

"Okay, Lao Zhou, I don't know you yet?"

Faced with what Mr. Yan said, the old man surnamed Zhou said immediately.

"It's okay Yan Tou, think about the propeller planes during World War I and World War II.

Aren’t the parameters of our thing better than those back then? Performance is fine! rest assured. "

What he said was indeed correct, and everyone once again focused their attention on the plane in the sky.

The plane climbed to an altitude of three thousand meters and changed to level flight again.

Lieutenant Wang is also at this altitude, cooperating with the ground tower to test various indicators of the aircraft.

After a series of tests, all indicators of the aircraft were within expectations.

As far as Lieutenant Wang's current driving experience is concerned, the aircraft's control, flight control, avionics, etc. all satisfy him.

But I just feel a little unsatisfied, and I always feel that the motivation is not so sufficient.

As far as the aircraft model is concerned, as long as the engine is more powerful, he can fly the aircraft better.

With this feeling in mind, he pressed the communication button with the ground.

"Call the tower, the bird calls the tower!"

"Received from the tower, any questions?"

"Xiaoniao applied to lift the engine restrictions, and will conduct a maximum ceiling test next! Please agree with the tower."

At the temporary tower on the ground, all the old men around looked at Mr. Yan.

Old Man Yan nodded seriously, walked to the phone, held the microphone in his left hand, and put the earphone on his ear with his right hand.

"Lieutenant Wang, I am Yan Hang, I allow you to lift engine restrictions,

In the highest limit test, please remember one thing: don’t take risks, everything is about safety.

If nothing matters, jump immediately and don't risk your own life. "

Lieutenant Wang was flying a plane, hovering over the Hongdu Aircraft Factory.

After hearing Mr. Yan's instructions, he nodded subconsciously, and then answered into the intercom after reacting.

"The little bird receives it, the little bird receives it, everything is about safety."

Lieutenant Wang released the button on the intercom and reached out to the instrument panel with his free right hand.

A switch with a cover on the instrument panel is particularly eye-catching. Open the cover.

The switch is exposed, flip the switch to the on position.

The moment the switch was turned on, Lieutenant Wang immediately felt that the plane he was sitting on was like a fierce horse unbridled.

The engine horsepower increases greatly, push the throttle valve all the way forward, and a feeling of pushing back is felt.

The speed of the plane increased a lot, and he also pulled up the control stick.

The plane was also making movements, with its nose once again at a forty-degree angle to the ground, and it flew toward the sky.

The flight altitude was increasing, the propellers were turning crazily, and the two engines were working desperately.

Soon the plane climbed to four thousand meters, but this was not the final point, the altitude was still rising.

4500 meters

5000 meters

5100 meters

5200 meters…

When the altitude reached 5,600 meters, Lieutenant Wang could clearly feel the strain on the engine.

When it climbed to 5,780 meters, Lieutenant Wang finally changed the attitude of the aircraft and turned it into level flight.

He knew that the engine had reached its limit at this time, and there was no need to continue.

If something goes wrong by then, it will not only endanger his safety, but also cause unnecessary losses.

As far as this aircraft is concerned, with its current power, it can rise to an altitude of nearly six thousand meters.

This is already a great achievement, although Lieutenant Wang still feels lack of motivation.

"Tower! Tower! The bird has now reached the airspace of 5780 meters.

The flight attitude has been adjusted to level flight, and the current flight status is normal. "

From the temporary tower on the ground, Lieutenant Wang's report reached the ears of everyone present through the loudspeaker.
