Chapter 2076

Speaking of Su-27, it is well-known in the military fan world. However, speaking of T-10, few people know. In fact, T-10 is the prototype of Su-27, which is the code name during test flight.

The Xiong Navy had long wanted a carrier based aircraft with fixed wings, so when the Su-27 had not been finalized, it began the experiment of carrier based aircraft.

In 1982, the Su-27 was still far from being finalized. The Sukhoi Design Bureau began to use the t-10-3 prototype to carry out ground sliding jump deck take-off and blocking landing tests. This -3 means the third prototype.

After improvement, repeated experiments were carried out on this prototype, such as sliding jump take-off, blocking landing, etc. on the nitka system. In the following years, other test aircraft were tested, such as t-10-25 prototype, t-10-24 with canard wing, t-10u-2, etc, They were not specially designed for shipboard, but were refitted. During the long test flight, due to lack of experience, these prototypes crashed successively in the test. In this way, until 1985, Xiong Guo Military Commission officially issued an order to the design bureau to develop su-27k. Their official t-10k prototype has also begun research and development.

From the beginning of design, this kind of aircraft is prepared for carrier. From the appearance, it seems to be the most unique duckling wing. In fact, the whole is very different.

For example, its wing area is increased to reduce the wing load and landing speed, so that the pilot can control it more easily. Its tail vertebra is shortened to avoid rubbing onto the deck during landing. Its front landing gear is replaced with two wheels, and the rear landing gear is strengthened to withstand the huge impact force during landing. Its flap slot is increased, Provide greater lift. In order to improve the control ability, analog telex is replaced by digital telex, and so on.

These can only be found by professional people, and they have to be carefully compared with the previous aircraft. Now, the most intuitive thing is that there are more pairs of small wings in front of them and they have become three wing planes. Facing this change, Qin Guan deliberately pretended not to understand what the other party said about t-10k and asked the other party, "what's the use of this?"

Our J-10 fighter is a canard layout fighter. The canard wing is used to pull the vortex. At the same time, it can also control the fuselage and greatly improve the pitching operation ability. However, now, the area of the canard wing is quite small, and the control force should not be large. Besides, the edge can be used to pull the vortex. What do you want the canard wing to do?

"Improve the longitudinal pitching control and increase the static instability." Simonov accepted to Qin Guan: "this kind of aircraft will become a carrier based aircraft of our navy."

Although the air force officers came to visit, they listened very carefully at this time. After all, the needs of the navy are more demanding. After being developed for the Navy, they can be used to improve the air force's fighters. They are still very interested in this new technology.

"No, no, this is not a carrier based aircraft." at this time, Qin Guan shook his head: "carrier based aircraft, the wings have to be folded. You don't even have a folded wing. What kind of carrier based aircraft should you be?"

Simonov blushed when he heard Qin Guan's words. Their t-10k-1 really did not have collapsible wings, which would not be available until t-10k-2.

After all, they have to catch up.

On the aircraft carrier, the space is narrow, and only the foldable wings of the carrier aircraft can reduce the floor area. Of course, the male cat is a special case. Its wings do not need to be folded, but directly shrink back to the end, and the transverse width is greatly reduced.

Now, Qin Guan pointed out to them that there are no folding wings. What kind of carrier plane should it be? Pretending to be a big tail wolf is actually a little white rabbit.

Simonov was embarrassed for a while and continued to explain: "our prototype mainly carries out take-off and landing experiments, so we don't fold the wings. We'll have it when the next plane comes."

Qin Guan continued to shake his head: "no, after folding the wings, the weight will increase. Now such construction is equivalent to a waste. After folding, it is found that the previous data are wrong, so we have to do it all over again."

After the land-based fighter is changed into a ship based fighter, its performance will decline a lot. The airframe should be strengthened, the landing gear should be strengthened, the whole body should be salt resistant, and the folding wing should increase the weight by about 10%. Therefore, there should be new schemes, such as using more composite materials to reduce the weight, replacing engines with greater thrust, etc.

If these technologies are applied to land-based fighters, the performance of land-based fighters will naturally continue to improve. This is also the reason why air force generals value it.

Now, Qin Guan continuously pointed out his mistakes. Everyone was looking at Simonov's embarrassment and knew that Qin Guan was not wrong. Now, Simonov is also fighting for time.

The competition between the two design bureaus is quite fierce. After all, MgO Yang design bureau is still a giant in military aircraft research and development. Although it has only won a contract for a front-line fighter on the third-generation aircraft, it has presided over the research on the fourth-generation aircraft. At the same time, in terms of shipborne aircraft, they are also responsible. The MiG-29 modified shipborne aircraft and the Su-27 modified shipborne aircraft, There will be fierce competition. Whoever comes out first and gets on the ship for test flight will have an advantage.

In particular, in terms of progress, Su-27 delayed because the radar problem could not be solved for a long time. They delayed for several years. In 1985, Su-27 began a large number of service. At this time, MiG-29 has been flying in the sky of Hans for several years. This is the gap. They are also in a hurry now.

"Anyway, the plane has not been assembled. If you lack the wing folding technology of the carrier based aircraft, you can go to us to investigate and improve it. Although it will be delayed for several months, it can avoid repeated work in the future." Qin Guan kindly reminded.

It's not difficult to refit. In history, when the t-10k-2 was built, the - 1 aircraft also went back to the factory and replaced with folded wings. Is it necessary to toss about like this? It's better to change it now. Although the J-11 in China doesn't need to fold the wings, the Yun-12, which is a mapping imitation of the S-3, retains the folded wings. Just look at it. It's very simple.

Qin Guan said to this extent. Of course, the other party can't refuse: "then we'll send technicians to investigate immediately. However, for us, the difficulty of carrier aircraft is not folding wings."

This folding wing is just a mechanical device. Now, they still have difficulties to tell.

Looking at Simonov's hesitation, Qin Guan smiled in his heart. Of course, I know your question. Is that enough?

"Its biggest problem is self-respect."
