Therefore, Zhuang Jianye is very tolerant of mareshevsky's requirements. He just wants to learn from Tengfei group's business experience. What's the point? As long as you keep the technology of carrier based aircraft, you can learn how you want, even if you let Zhuang Jianye, the leader of the take-off group, do a pole dance.
Even if the core business is liberalized, Zhuang Jianye will be more generous in terms of funds. Doesn't mareshevsky want us $3 million? Zhuang Jianye directly approved US $6 million with a big hand.
It is required to complete the trial production of jacques-41m VTOL model and Zhenlong V model within two years.
Maleshevsky agreed very simply. He beat his chest with his fist, which was a thump. He said with pride that if he couldn't do it, he would hang naked for ten days and a half months in the winter.
In a word, it's just that if you leave this matter to me, you can put your heart into it.
Facts have proved that maleshevsky, an old comrade left over from the Soviet era, is very reliable. Since March 1996, maleshevsky has successively called together university professors, technicians from scientific research institutions and skilled workers in factories who used to work in Yakovlev Design Bureau.
In less than half a year, a total of six tons of technical data were collected. Then, according to these data, jacques-41m vertical take-off and landing fighter and others drew the design drawing and production model of jacques-41m vertical take-off and landing fighter.
On this basis, the original jacques-41m VTOL fighter has been systematically optimized, so as to upgrade it to jacques-41mk VTOL fighter, that is, at present, the Zhenlong V VTOL fighter is carrying out adaptive production in the general assembly line of pulse III aircraft in No. 0 workshop of Tengfei group.
"This fighter. The wd-70st turbofan vectoring engine is used, with a maximum thrust of 15.8 tons, a total mass of 1.82 tons and a thrust to weight ratio of 8.3... "
After introducing the history of Zhenlong V VTOL fighter, Zhuang Jianye began to talk about the specific performance indicators of Zhenlong V to the two leaders. The leaders had been smiling, but the leaders in the army listened very carefully.
Seeing that there was no superfluous expression from the two leaders, Zhuang Jianye continued: "the engine is our take-off group. Aeroengine Manufacturing Co., Ltd., based on the Russian r-79 turbofan vector engine, is improved. The biggest feature is that the nozzle can achieve a 60 degree downward deflection, and can provide a maximum lift of 10.5 tons. Cooperating with a wd-28st turbofan lift engine at the rear of the cockpit, the lift of 4.2 tons can be achieved, so as to realize the Zhenlong V vertical take-off and landing operation. "
"As far as I know, the jacques-41m VTOL fighter uses two turbofan lift engines." Hear here army inside big leader interrupts suddenly the words of mucous. Interrupt Zhuang Jianye.
Zhuang Jianye nodded: "yes, old chief, the jacques-41m VTOL fighter uses two rd-41 turbofan lift engines, but this layout is obviously too complex, and the later maintenance and production costs are too high. Based on this point, we reduced the two turbofan lift engines to one, which is our real dragon V different from the jacques-4 The most important characteristics of 1m VTOL fighter. "
Wen Yan, the leader of the army, didn't say anything more. He just made two rounds around the assembled real dragon V VTOL fighter with great interest. Then he rubbed his chin and asked thoughtfully, "it seems that the layout is still different from what you declared?"
The implication of the military leader is that the aerodynamic shape of Zhenlong V seems to be different from that of jacques-41m. It is obvious that the military leader has seen jacques-41m before, otherwise it is impossible to see the difference at a glance.
Zhuang Jianye is not proud of this. After all, what he is looking at is the real dragon V evolved from jacques-41mk. If it's the same, it's the hell.
So he immediately replied: "we did make some changes. The relevant data have been collected and will be reported in the near future. Because before the trial production, we found that the previous design was problematic through theoretical calculation and wind tunnel test, so we made a series of changes in the aerodynamic layout, such as adding a large wing..."
With these words, Zhuang Jianye made a sketch at the wing root front of the real dragon V being assembled: "the original design version of the strake wing was just at the wing root front, a very small strake. Now we not only enlarge it, but also extend the strake to the air intake port, so that the aircraft can obtain extra lift, at the same time, it can also obtain extremely strong maneuverability. In addition..."
In the initial design, the rectangular inlet similar to the MiG-25 was adopted. After our calculation, the efficiency of the inlet was not the best at low speed of subsonic speed, but it was very good at supersonic speed. Therefore, we learned from the adjustable inlet of f-15c and added an adjustable inlet Device. "
"And the wings..." Zhuang Jianye turned around and patted the wing behind him: "we increased the wingspan from 10.1 meters in the initial design to 12.4 meters, and adopted a more advanced wing folding device. Not only the overall flight performance is better, but also the folded space area is roughly the same as the initial design By the way, we have also changed the inclination of the final vertical tail, from 3.5 degrees to 12.5 degrees. Not only that, we have also integrated the new technology of full motion vertical tail, which improves the mobility of the aircraft qualitatively. "Zhuang Jianye made a very detailed introduction to each part and purpose of the trial production model of Zhenlong V that was being assembled. The leaders and leaders were amazed. But when people thought it was an impeccable advanced combat aircraft, Zhuang Jianye changed his words: "of course, it took a certain amount of effort to apply so many advanced technologies and techniques Among them, the biggest impact is the total structural capacity, which has increased from 28 tons to 32 tons, and the weapon load has decreased from 2.6 tons to 2.2 tons.
However, we are making the next improvement plan to further increase the proportion of composite materials in the aircraft interior, so as to increase the proportion from 25% to 38%. After the improvement, the maximum take-off weight of Zhenlong V will be maintained at 29 tons, the maximum payload will be increased to 3.2 tons, and the maximum payload during vertical take-off will reach 2 tons, and other indicators will not be lower than the present Today's third generation combat aircraft are generally equipped. "
Speaking of this, Zhuang Jianye pauses for a moment, then leads the big leaders and army leaders to walk outside workshop zero, and continues to introduce: "this is our plan for the first two stages of the development of Zhenlong V VTOL fighter. In the future, we will carry out the third stage improvement, that is, on the basis of the improved Zhenlong V, combining with the next generation combat aircraft The application of technology to launch radar stealth version of the VTOL fighter.
Of course, it all depends on the development of the present stage. However, Tengfei group is confident that it will turn its ideal into reality for the sake of the cause of the people's Navy! "
After listening to the military leaders, they nodded with approval. However, when they came to the gate of No.0 workshop, they suddenly stopped. Then they looked at Zhuang Jianye and asked what made Zhuang Jianye's heart beat faster: "after reorganizing China's take-off on the basis of the take-off group, what are your main business directions besides supporting naval aviation ?”
