Others also came over one after another to watch Fang Hao fish the nose of the machine.

The pilot's cockpit in the nose of the plane is missing. It must have been ejected when the plane crashed.

But this is not the key.

Whether the pilot's cockpit is present or not will not affect their subsequent research.

On the contrary, for Fang Hao, he was relieved. At least there was no pilot inside, which meant that the body was useless.

If the pilot's cockpit is still there, it means that the plane was not ejected when it crashed, and the body would still be on the nose of the plane.

That means he caught a corpse again.

Although Fang Hao has caught many corpses and has long been used to it, he should avoid catching them if he can.

He doesn't want to catch a corpse again.

Two fighter aircraft research and development experts were the first to run to Fang Hao and looked at the newly caught aircraft head at close range.

Seeing this aircraft nose, the two experts were extremely excited.

This is the nose part of the F22 Raptor fighter jet.

The things inside have always been their dream research objects.

After all, as the world's first fifth-generation fighter aircraft in service, the F22 has always been the subject of research and simulation.

In the past, everyone could only guess and analyze based on some displayed data, and many things were not very accurate.

There are no real objects for reference, so many things are based on guesswork.

Although the nose of the aircraft in front of us is seriously damaged and the fuselage may have been broken into several sections, some of the instruments and radar inside are of great reference and research value.

It is equipped with a passive phased array radar that can detect enemy aircraft using enemy radar waves without emitting electromagnetic waves, and an/apg-77 active phased array radar with an extremely long detection range. It is a key equipment for beyond visual range combat.

.

These can all be studied and can also make up for our shortcomings in this area.

Do you think these two experts are excited?

These things are so precious.

The AN/APG-77 radar used by the F-22 uses phased array technology with more than 2,000 transceiver components. Each component uses microwave integrated circuits with GAAS substrate technology. This substrate has a high electronic drift rate.

High breakdown voltage.

However, our phased array radar GAAS substrate technology has not yet been fully developed. There is about an order of magnitude gap with Takako's technology in terms of electron drift rate and breakdown voltage, resulting in the microwave amplification capability of a single transceiver component of our radar.

, the circuit amplification capability is much smaller than an/apg-77.

Therefore, in order to achieve the same detection distance, more transceiver components and a larger antenna aperture are needed, which brings two negative consequences to electronic performance.

The first is the increase in radar side lobes, and the second is the sharp increase in power consumption.

There is also passive radar. Passive radar mainly analyzes the signal of the other party's radar to warn itself or serve as the basis for electronic interference.

The gap between us is even more obvious.

It disperses its own radar energy in a wider frequency domain and synthesizes a narrower bandwidth when receiving. Then our radar receiver cannot fully accept its radar signal energy, although the final result may or may not be

Receive and analyze the radar signal of the F-22, but it takes several minutes.

Secondly, there is still a gap in the algorithm and sensitivity of the radar receiver, which makes the processing of weak energy signals insufficient.

In addition, the optoelectronic system, high-precision d lens and infrared sensor are far less accurate than Yingzi.

So catching this machine head means something really different to us.

They determined that the nose they caught was the nose of the F22.

"With these things as reference, we can further improve our new generation of fighters, improve our aircraft, and create a better targeted combat method."

It’s really like crossing the river by feeling the eagle’s wings.

Moreover, you can also carry out some countermeasures and upgrade some countermeasures according to the opponent's fighter aircraft, which will give you a higher chance of winning in future air battles.

First there was f35, and now there was f22... This time, Takako's cards were really almost gone.

“It’s really amazing.”

Captain Han really admires Fang Hao this time.

Only by seeing it with your own eyes can you feel such a shock.

You can really catch these things by fishing.

After catching the nose of the machine, everyone gathered around and looked at the nose of the machine curiously.

At this moment, they completely forgot how much effort it took to catch a machine head.

"Is this the nose of the F22?"

"I just saw pictures on the Internet before."

"It's so beautiful."

"But I feel it is not as good as our sword 20."

"Of course, this is a product from decades ago after all."

"But there are still many things we need to study about this aircraft."

The surrounding coastguards were also discussing in low voices, and they were all attracted by the fished nose.

"Yes, it would be better if we could catch the engine at the tail of the plane."

"Yes, the engine is our weakest aspect."

"It depends on whether we can catch the engine from behind."

Everyone began to look forward to Fang Hao's performance later, to see if he could catch the engine part.

After catching one, everyone is thinking about the next one.

The pressure was put on Fang Hao again.

Fang Hao once again became the hope of the whole village.

It depends on whether he can still catch the plane's engine.

As long as the engine is caught, the wreckage of this F22 aircraft will basically be considered complete.

As for other scattered small parts, they can be ignored.

Mainly if we can get these important things, that would be great.

Radars, avionics systems, and engines...these are the most important ones.

There is also the black box. If you can find it, you can obtain the flight data information inside, which will also be of great help.

After Fang Hao caught the nose of the machine, everyone now has full confidence in him.

The coast guard on this ship also looked at Fang Hao as if he were an alien.

There is a big difference between hearing about it and seeing it with your own eyes.

It’s a really different feeling to see the other party fishing the nose of the machine with your own eyes.

After fishing the machine head, Fang Hao felt much better and his confidence increased again.

It seems that I still have hope of catching all the remaining fuselage parts.

Now that the nose of the plane has been caught, the only thing left is the chicken butt... ahem, the tail of the plane.

The importance of the tail of the aircraft is not generally high, because their engines have always been our covetous ones.

The F22 engine uses two F119-PW-100 afterburning turbofan engines. The afterburning thrust of a single unit can reach 155.7 kN, and the thrust-to-weight ratio reaches 10. When the afterburner is not turned on, the aircraft can fly at supersonic speeds.

The cruise takes about half an hour.

This gives the F22 ultra-high maneuverability and the ability to cruise at supersonic speeds.

This is also the aircraft that is still the world's first-tier fighter aircraft.

Some people even pointed out that there is still a gap of more than ten years between our Jian 20 and the F22 in terms of engine level.

Why does our Jian 20 need a canard layout? It is because of the level difference between the engines that we have to adopt a canard layout so that we can have higher maneuverability.

The canard layout is a genius design that improves lift and maneuverability.

But this also exposed the slightly weaker capabilities of our engines.

However, in recent years, with the emergence of our new engines, this situation has improved a lot.

The gap with Yingzi is also rapidly shortening.

But this... the gap still exists.

If we can get Takako's engine, it will save us a lot of detours.

Of course, the most critical factor that restricts our engine capabilities now is materials.

The most fatal thing is that our materials cannot keep up.
To be continued...
