Chapter 2897: Three models take off together

Since the visitors had demand, Qin Guan could only follow Feng accompany him, and on the next day, he came to the flight test institute.
Now the Han State Flight Test Institute has become a giant. Here, there are many advanced aviation equipment of Han State, which are undergoing intensive test flights. Of course, what you want to show to the Davids is naturally The F-31 fighter is out.
Although such fighters frequently appeared in newspapers, they could not be compared with on-site observations. This was the first time I saw Han's advanced aviation equipment and the fourth-generation aircraft, Rafael and others were still full of expectations.
Qin Guan also had expectations in his heart. After all, it has been several months since the last time I saw the J-31 fighter. In these months, what progress has this fighter made? How far is the flight test subject? Can you catch up with this year's air show?
Amidst such doubts, Qin Guan saw a F31 fighter on the tarmac that was preparing for a test flight.
The body of the entire fighter aircraft looks huge and bloated. Because it was a test flight, it was not painted with a stealth coating. The most common yellow paint was used. On the nose, there was a 04 mark. It seems that this is the fifth one. Prototype.
With sufficient funding guarantees, the progress of this project is also very fast. After all, 6601 has been holding back for so many years, and now they are finally about to usher in their own take-off, how can they not race against time?
However, this plane is a bit strange, right?
When Qin Guan stood in front of the plane, Qin Guan felt a little different from what he had seen before, and then realized that the tail nozzle of this plane was not a three-section rotating nozzle.
"When we designed this kind of aircraft, it belonged to one aircraft and three types." Just after everyone arrived, the chief teacher and old grandson on the scene began to introduce to everyone: "01 and 03 have been tested and flown away. , This 04 is different from the others, this one is a conventional take-off and landing model."
That's it!
In order to speed up the flight test progress, it is necessary to build a few more prototypes, 01 and 03, both of which are vertical take-off and landing models, and are undergoing test flight, and this one is a conventional take-off and landing model.
"Well, the progress is fast." Qin Guan said.
Lao Sun scratched the back of his head and said with a smile: "According to the plan, the 05 is a ship-based model and is being assembled on the production line. It is estimated that it will take two months. After that, we will have all three models."
In fact, among the three models, the vertical take-off and landing model is the most difficult. After the vertical take-off and landing model is developed, the other models are logical, just removing the front lift fan part and turning it into a fuel tank and equipment. That is the conventional model, with enhanced landing gear and anti-salt treatment. This is the shipboard model.
At the same time, the test flight of these models will speed up the project, because those vertical take-off and landing fighters can also take off and land routinely. The flight control in normal flight is also the same, so that it can maximize the improvement. The flight test of the aircraft is in progress.
Only verification of vertical take-off and landing is enough. There are 01 and 03 aircraft. Other models are also undergoing test flights, which saves time to the greatest extent and allows the aircraft to be finalized earlier.
"This plane, can we take a look at it first?" Seeing that the people around were already preparing to take off, Rafael was shocked and asked.
Lao Sun nodded.
Therefore, Rafael was not polite. First, he stepped on the ladder and climbed into the cockpit. According to the outside world, the cockpit of this fighter aircraft is quite sci-fi, with only a large-area display screen in front. Is that true?
Sure enough!
When Rafael saw the furnishings inside, he couldn't help but be amazed. It's such a layout, it looks so simple and capable, and a large screen can only be done by Han!
As for the joystick, it is not in the middle. This fighter has a side stick arrangement, which allows the pilot to withstand greater overload. It seems that the maneuverability of this aircraft is also quite high!
With comprehensive stealth capabilities and such a high degree of mobility, it is conceivable that Han has completed these integrations, allowing this fighter to exert greater effectiveness, and it is definitely the world's first.
Eagle country's joint fighter? It’s too early to serve! It seems that if you really buy twenty from here, it's not a bad thing.
While Rafael sighed in the cockpit, Qin Guan, together with Graça and Lao Sun, circled the plane, and then came to the tail. "In terms of combat effectiveness, this is still the highest, and the nozzle does not need to be deflected downwards. Therefore, we installed the latest omnidirectional vector nozzle for it." Lao Sun pointed to the nozzle at the tail and said: "This way , Fighters can have super-mobile capabilities."
Super mobility! As a fourth-generation aircraft, it must have 4S indicators. One of the important aspects is super-maneuverability. Compared with conventional fighters, its vector nozzle allows it to have more aerodynamic torque, so that it can make some The maneuvers that conventional fighters cannot make, or even some maneuvers that violate the basis of aerodynamics, are super maneuverability.
This vector nozzle is very important.
Even F22, in order to simplify, only a baffle is adopted, which can realize the vector function most easily, but the loss is relatively large, but the current vector nozzle is not like this, and all the power can be deflected. Suffer any loss.
After adding it to the flight control computer, it can be cross-linked by flying fire. At that time, don't look at this bloated and bulky body, it is good to abuse the third-generation aircraft.
Qin Guan also nodded in satisfaction. In fact, this vector nozzle has already been pre-researched. Its biggest problem is its life span. As for how long this life span is, Qin Guan will never ask here. Ten hours, isn’t that just showing up?
"Yes, at the air show, let it be shown to the world once to see the advanced performance of our aircraft." Qin Guan said, his eyes have already appeared one by one classic maneuvers, what super Cobras and falling leaves can be easily displayed on an airplane of this kind.
There was an expression of envy in David's eyes, and it seemed that he was drooling, and finally left the plane, standing far away, watching the start of the plane.
The test pilots easily operated the plane and took off with full afterburner. After flying for a short distance, the plane was pulled up, and the tail nozzles were displayed in front of them. Rafael sighed and said: "This should be the world Did you get the second fourth-generation turbofan?"
