Chapter 501: Constant Improvement

Most of the people who came were aircraft designers, so everyone immediately studied this aircraft.

The technicians on the assembly line are still busy back and forth, so everyone can't get close to observe, but can only come close to observe.

The Mirage 3 is intake on both sides, there are air intake cones, which is the most significant sign, at this time, the fuselage of these fighters has been produced, and you can see the pair of canard wings on both sides of its air intake cones, which is the most interesting to everyone.

"The improvement of your Cub fighter is worth learning from." Song Lao said with a sigh.

This time, General Lin did not come out with him, Song Lao was the captain of the team, and when he looked at this plane, he was quite emotional.

The Mirage 3 is only an authentic second-generation aircraft, and it is produced by Dassault, but now the Israeli aircraft engineers in front of them have eaten all the technology of this aircraft, and then on the basis of this aircraft, they have made a reborn improvement, the tail is thickened, the latest engine is stuffed in, and the canard wings are also added in front to improve the performance of the aircraft.

The improvement of this aircraft is of great significance to our own reference, because we are now also improving the MiG-21, this authentic second-generation aircraft, in our own hands, but also to carry out large-scale improvements, nose air intake, new engines, and finally become a quasi-third-generation aircraft.

Learn from them!

"Yes, we have also put a lot of effort into the improvement of this aircraft." In the face of the praise of the Chinese guests, Salaf was also full of emotion.

The current lion cubC7,It's already the final version,Before that,The most important version is the lion cubC2,After repeated research,Absolutely on its aerodynamic shape income,At the beginning,They once added a long nose to the phantom3,It looks quite alternative,At the same time, on both sides of this long nose,Also added a side strip,This side strip is not a vortex,The main thing is to improve the airflow of the air intake。

However, after installing it, it was found that there was a problem, although the airflow was improved, but in the case of high angles of attack, the fuselage began to tremble.

Later, one of the test pilots suggested a sawtooth on the leading edge of the wing to eliminate the high angle of attack chatter. It can be seen that in Israel, test pilots are quite capable, and they are often in the role of test flight engineers, who can provide some very constructive advice.

After repeated test flights, the long nose was eventually abandoned, and they added canard wings to the front of the aircraft.

After this canard wing is installed, there are advantages and disadvantages, for example, the disadvantage is that it increases the drag of the aircraft, and at the same time it has its own structural weight, in order to place it, the corresponding airframe must also be strengthened, but this method is finally retained.

First of all, it increases the total area of the wing and reduces the wing load, the lower this figure, the better the maneuverability of the aircraft.

At the same time, it also moves the aerodynamic center of the aircraft forward, although the stability has been reduced, but the maneuverability is greatly improved, and the aircraft is more sensitive.

Of course, as a canard, vortices are naturally generated, which help to increase the lift and drag of the delta wing behind, increasing the maximum limiting range of the aircraft's angle of attack. (Increasing the drag is the drag brought by the canard wing, reducing the drag is the vortex pulled out by the canard wing, which reduces the drag of the main wing behind, and the two are not the same concept.) οΌ‰

The improvement of this aircraft alone has made them rack their brains, but there are also benefits, and after this improvement project, they have cultivated a large number of professional aircraft development teams, and they have a lot of experience, which is why they can carry out new projects.

Thinking of this, Saraf is also very emotional, now, looking at the fighter being assembled, he continued: "The models we are producing now, mainly on the basis of the previous models, have been replaced with a lot of newly developed equipment, for a fighter, the life of the fuselage will be very long, but the avionics equipment on it will age rapidly, so it is necessary to replace it with new equipment." ”

Hearing Salaf's words, Song Lao's eyes suddenly lit up: "So, in your understanding, how important is the airborne equipment?" ”

At the beginning of the bidding, the 601 Institute's view was that those complex avionics were useless, as long as the simplest mature avionics could be used, but Song Lao's view was the opposite, in the future air battle, the dependence on advanced avionics equipment is quite large, if there is no advanced avionics equipment, then there can be no victory in the future air war.

At that time, the experience of the Vietnam War was carefully studied in China, and the MiG-21 repeatedly defeated the ghosts, but that was all in the past, and we must look forward!

Now, in foreign counterparts, what do you think? Song Lao wanted to know very much.

"It's critical." "Our brilliant victories in air battles in previous years were inseparable from advanced avionics, and the shoddy Soviets had nothing but the fate of being shot down in front of us," Saraf said. Salaf said firmly.

Now the stability of avionics has improved, and without this, it is impossible to win future air battles! It was by virtue of this technological superiority that the Israeli Air Force was able to ravage the Syrian Air Force and achieve an 82-0 record.

"Can you tell us about the aircraft's avionics?" At this moment, another old man in the delegation spoke, this old man was the chief designer of the 1471 radar, Ben Lao, who was most interested in the avionics system.

"Absolutely." "Come here, we have an assembled cockpit here, you can take a look," Salaf said. ”

Israel is quite generous, just like the last time they happily agreed to export the Monster Snake-3 missile, and now, they show everyone the avionics system of the Cub.

"Our core avionics system, which is produced in-house, was previously the WDNS-141 weapon delivery and navigation system, and now the WDNS-391 system. The system includes Elbit's mission computer, IAI's Tamam division's central air data computer and inertial measurement unit, El-Op's head-up display, and Elta's EL/M-2001B ranging radar, which is still a ranging radar but has excellent ground clutter filtering in downward-looking mode. When carrying out ground bombing missions, it is quite efficient. ”

While talking, everyone walked to the side of the plane that Saraf said, since they said that they could visit, then Qin Feng was the first to jump on, and the moment they saw the cockpit, they drooled.
