Chapter 1422: New Jianshi

Chen Rui looked at the outside window and could see that this was everything he had been familiar with. The runway of the 1132 factory, on the tarmac beside it, could see the beautifully shaped fighter plane with its main wing at the back and canard wings at the front. , It seems to make it look very spiritual.
Once, Chen Rui was the test pilot of this aircraft, but was later asked by the navy to fly to simulate the take-off and landing of the aircraft carrier.
Now, seeing this plane, Chen Rui is also very kind.
"Xiang Jing, Andrew, you, Yutong, Xiaoxia, Xiaolu and others will first go to the hotel to stay. It is late today, and tomorrow we will go shopping in the city. The scenery here is also very beautiful." Qin Guan said.
After getting off the plane, there was already a car to greet him. After sending away the others, Qin Guan took Xiucai and Chen Rui straight to the apron.
"Something is different." Chen Rui saw the clue from a distance, and then Chen Rui suddenly discovered something: "Its engine has been changed."
In the past, this fighter used a Spey engine. Although it has been modified to improve its power, it is already at its limit. Its aerodynamic layout is very advanced, but in many cases it is dragged down by the engine.
Now, when they approached, Song Lao and others greeted him.
"President Qin, thank you for bringing us the engine." Song Lao said.
Relying on the last incident, after the negotiations, the Eagle Nation provided a batch of engines. Most of these engines were snatched by the navy. They wanted to use them on their J-11 fighters, so they were divided into five. After getting the station, everyone quickly matched it, and now it is finally placed on this J-10 fighter.
For the Spey engine, the thick outer nozzle is fixed and cannot perform any movement, but only serves as a rectifier. The inner layer can perform a small range of convergence actions. This double-layer nozzle is actually outdated. The nozzles of the current three-generation engines can be converged and expanded as a whole, which can effectively improve the jet's effectiveness.
Now, from the outside, Spey’s nozzle is just a cylinder, but the engine in front of us, with the nozzle backwards, is in a contracted state, which looks different.
"I have to thank Chen Rui for this matter." Qin Guan said with a smile: "Without that good thing, how could we get this kind of engine."
The Yingguo people are very cunning. They only gave dozens of engines with matching air flow and other materials, but they didn't give any technology. In this case, Han will have to ask Yingguo for help in the future.
They certainly won't know that they are already developing new third-generation engines. These engines are only temporary, just to make up for this unacceptable vacancy.
"Chen Rui, have you only noticed that the engine has changed?" Qin Guan said to Chen Rui.
When Chen Rui just stared at the engine, after all, Chen Rui knew that there was the shortcoming of the J-10. As long as the engine was changed, the performance of this fighter could be truly brought into play.
But now, after hearing what Qin Guan said, Chen Rui finally began to focus his gaze on more places, and he saw it right now. There are also some differences in front of it.
In order to improve the maneuverability at high angles of attack, it adopts the method of belly air intake, and the air inlet adopts an adjustable rectangular air inlet. In this way, it can provide excellent air intake ability at various speeds. This section attaches importance to the need for air combat interception capabilities.
And now, the baffle above the air inlet is gone, and the six sticks are gone. What Chen Rui saw was a big drum bag!
Qin Guan also stared at this thing with appreciative eyes. Unexpectedly, Song Lao and the others had mastered this air intake technology.
This kind of thing, the scientific name is called the supersonic inlet without a surface layer clapboard. It has already been adopted on Xiaolong fighters. However, it is not just a bulge. It requires complicated fluid dynamics calculations. Yes, our current computer capabilities have already reached, and Mr. Song and the others actually used this technology on the J-10 fighter plane. In later generations, this is the level of the J-10 B.
This kind of bulging air inlet has many advantages, simple structure, light weight, low resistance and improved invisibility.
Compared with the previous adjustable intake duct, it can save more than 50% of the weight. For the fighter, the lighter the weight, the higher the maneuverability. At the same time, this bulge will have the effect of With occlusion, you can simply improve your stealth ability.
Of course, it also has its downsides. Although it has been repeatedly optimized and designed, it has no adjustable ability after all, and it cannot achieve the best air intake at all speeds.
Compared with those advantages, the only shortcomings are acceptable. Besides, there is already such a powerful engine. "Lao Song, is there a flight test project today?" Chen Rui said, he couldn't wait.
After getting an affirmative answer, Chen Rui hurriedly ran to the pilot preparation room, and soon changed a set of flight equipment from there.
Since Chen Rui made an emergency landing on the opponent’s plane, he has not flown until now. For a proud man in the blue sky, this is simply intolerable. Therefore, Chen Rui has long wanted to fly. Unfortunately, brother-in-law’s The meaning is obvious. Before Xiaoxia's belly bulged, she was afraid that she would not want him to fly, but now that he finally had this opportunity, he could not wait to fly right away.
He was holding the flight helmet in his hand. At this moment, he didn't immediately climb into the cockpit. He said to Song Lao, "What is the shelf on this helmet?"
He has already discovered that there is an extra metal plate on his helmet with a card slot on it. It seems that other things can be added?
"Helmet sight?" Qin Guan said in one mouthful: "It seems that our research and development in avionics will finally exceed the world's advanced level."
Qin Guan recognized it at a glance. In later generations, this is something very mysterious to say.
The helmet sight, as the name suggests, is an aiming device combined with the pilot helmet. It is composed of helmet, display, head position measuring device and onboard computer system.
The most important thing about it is follow-up, that is to say, where the pilot's head rotates, it will be able to stare at it.
If specifically, after the pilot finds the target, he can track the target by staring at the target through the mark in the display; the head position measuring device is used to measure the angle of the pilot's head rotation to obtain the angular position of the target relative to the carrier; The computer converts the target position information into aiming instructions, and controls the missile's seeker, turret, radar or other photoelectric detection devices to track the target.
The helmet sight is easy to use, quick to aim, convenient for visual search, and has a large tracking range. It is suitable for launching guided weapons or for positioning and tracking of radar and photoelectric detectors.
Therefore, after its emergence, it was considered a revolution. In later generations, it was first equipped with the introduced Su-27 series fighters. However, pilots did not use them much in training, so their helmets only had a shelf. That's all, anyway, the aircraft doesn't carry missiles, and it's useless to carry it, but if it is cruising in actual combat, it will be carried.
Now, Qin Guan didn't expect that he already had such a thing.
