The country is still equivalent to the technology of the sixties, when you open the country, when you come out to see, you can find that you have completely outdated, a simple test run, you can also see a huge gap, many projects, people can do it on the ground, the computer nephew will measure the various parameters of the aircraft to show it.

On the tower of the test flight station, there is also a telemetry tracking system, the general test flight, will be carried out locally, this system, more advanced than the French one, not only can watch the various attitudes of the aircraft in the local tower, but also can be thousands of miles away from the Edwards Airport in California test flight, by the 25,000 miles above the synchronous satellite transmission of all the test information on the aircraft!

Synchronous satellites, now in China, are still developing synchronous communication satellites, and for people, the use of communication satellites to transmit experimental data is a fairly simple and common way.

"It is these gaps that make us determined to keep working hard." The day's visit was over, and when he returned to the hotel, Tu Lao looked preoccupied, he looked at Qin Feng, and couldn't help but say.

If this kind of aircraft is introduced, it will definitely have an impact on the new domestic J-1 project, but it will not affect the 132 factory, which has now become a domestic star enterprise by relying on the export of the J-7, and the capital flow of the factory is also quite abundant, so there is no need to worry too much.

However, if we continue to lie on this achievement and sleep a lot, it is absolutely not possible, and it will not take ten years for the third-generation aircraft to expand rapidly, and when the time comes, if the 132 factory does not want to forge ahead, it will lose the export opportunity in the international military aircraft market. The sky in the future will definitely be the world of third-generation aircraft.

"Yes, Elder Tu." Qin Feng said on the side: "Today's visit has made us gain a lot, I have an idea, can our Jianqi carry out a big sword and axe improvement?" ”

At present, the improvement of the Jian-7 is constantly being carried out, introducing avionics, increasing the payload capacity, increasing the number of missiles, etc., and it has been changed to a good and impressive level, and it is still an international alliance with the Marconi company.

However, what does Qin Feng's so-called improvement of the big sword and axe refer to?

"Qin Feng, go on." General Lin said.

"For example, change our J-7 from the nose air intake to both sides of the air intake, or belly air intake, empty the nose, install modern radar equipment, improve the shape of the wing, make it have better flight performance, improve the engine, increase thrust, and even replace it with a new turbofan engine, so that its combat effectiveness can reach or approach the level of the F-16, in this way, our J-7 will definitely be able to continue to produce for another 20 years."

Qin Feng's series of thoughts made Tu Lao pat him on the shoulder vigorously: "Yes, your idea is very good, very good!" ”

Then, Tu Lao turned around, looking at Tu Lao's back, Qin Feng couldn't help but ask General Lin beside him: "Am I not right?" ”

"Qin Feng, what you said is very right, but what is the difference between you saying this and redeveloping an aircraft?" General Lin said: "Change the nose, improve the gas, change the wing, change the engine, is there another one that is the original Jian-7?" ”

Qin Feng's idea is too beautiful, but it's a pity that he didn't take into account the reality, and if he wants to make a big change like Jianqi, it is definitely not something that can be done by domestic technology, let alone the factory design office of Factory 132 led by Tu Lao.

So, it's just a good idea.

General Lin also saw this very clearly, Qin Feng shook his head: "It seems that I am too naïve." ”

This day's inspection opened everyone's eyes, and the next day, when I came here again, I finally saw the test flight of the Tomcat fighter.

On the airport, the roar and hissing of the engine were so kind, Qin Feng held the binoculars and looked at the Tomcat fighter from afar.

At the time of takeoff, the wings of the Tomcat fighter were all deployed, and the engines in the tail burst into flames, pushing the fighter to glide on the runway, take off, and quickly rise into the sky.

Although the thrust-to-weight ratio of the engine is not high enough, the design of the variable sweep wing makes it perform quite well at low speeds, so it leaves the runway at a low speed and can pull up quickly, which is quite important for the navy.

When everyone saw the Tomcat fighter take off, with a chic attitude, it flew into the blue sky, and then, all entered the tower, and looked at various data of the plane through the tracking system here.

"Its climb rate is not low at all." When he saw the above data, Qin Feng suddenly muttered, this kind of aircraft, the thrust-to-weight ratio is only about 0.7, but this climb is too fast, this kind of can't play tricks, just rely on real skills.

Hearing Qin Feng's words, Pelehack immediately showed confidence on his face: "Of course, this is the advantage of our design, its variable sweep wing, giving it a very strong performance, in all kinds of airspace, all kinds of speeds, all kinds of packets, it is the best." ”

Qin Feng suddenly figured out something, bragging, right? It's clear that you don't have enough fuel when you take off!

The oil volume of this fighter is six or seven tons, this kind of test flight, half a ton of fuel is enough, the weight is light, so that its thrust-to-weight ratio can reach about 9, in this way, of course, it will make its climb more rapid.

It's definitely a slippery head, and now I'm here to brag about it.

"Mr. Pelehaq, shall we have a chance to experience its flight?" Qin Feng asked Pelehak, as a test pilot, of course he wanted to fly once.

"I'm sorry, we don't have such an arrangement." "If we can sign a purchase agreement, we can arrange for a special one to fly for you," Pellehaq said. ”

Grumman is not as real as Dassault, and their aircraft does not have the form of a tandem trainer, and it does not make much sense for a test pilot to experience it alone in the rear cockpit.

"In that case." Qin Feng said: "Then do you want to experience the confrontation between this aircraft and the MiG?" ”

"Of course, we have our own MiG aircraft, we often engage in confrontation by ourselves, and the performance of the Tomcat fighter is far superior to the MiG aircraft. IMHO, your MiG-21, oh no, is a J-7 fighter, and in front of our Tomcat fighters, there is no chance of winning at all. ”

Qin Feng was happy in his heart, the opportunity came.
