Chapter 450: A Duck Wing That Is Not a Duck Wing
Qin Feng likes duck wings, when he was in Chengdu, he came into contact with the duck layout fighter from Song Lao, and from there, he began to have a special feeling for the duck layout, in Qin Feng's place, he always felt that the duck layout of the fighter was the most beautiful.
Compared with the ordinary normal layout, the biggest feature of the duck layout is the positive lift, if you want to fly, the lever will look up directly, unlike the ordinary layout, the butt goes down first, and the head can be cocked, which is the power of positive lift, so the duck layout is also called the head-up layout.
There are many functions of canard wings, followed by the vortex generated by canard wings, this vortex can effectively improve the efficiency of the wing, so that the wing has a good aerodynamic efficiency at the high angle of attack, it can be said that the canard wing is the best choice for the fighter with the engine is not powerful.
The fuselage of the J-8 is very long, if a pair of canard wings are added in front of the fuselage of the J-8, the performance of the fighter will definitely be greatly improved!
It must be movable, fixed canards, only have the effect of generating vortices, and the movable canards can really be used as a control rudder surface.
However, in this case, the control is even more complicated, after all, the J-8 was originally a normal aerodynamic layout, so that it will become a three-wing aircraft? This must be quite troublesome to control, and it can only be controlled by fly-by-wire.
When Qin Feng was just now, he was definitely not offended, but he was excited all of a sudden, this will definitely greatly improve the mobility of Jianba, and the experts of the 601 Institute finally began to take big strides forward.
Mr. Gu didn't continue to look at his relative, he moved to the report.
"We know that the static unstable layout can effectively improve the maneuverability of the fighter, our J-8, originally statically stable, if you want to become unstable, you must advance the lift center, so we increase this pair of canard wings, mainly to move the lift center forward, turn our static stability layout into an unstable layout, related wind tunnel experiments, we are about to launch."
It turned out to be a fixed canard! Qin Feng's eyes were a little disappointed, and, listening to what Mr. Gu meant, this canard wing does not have any canard wing effect, does not produce vortices, does not use the rudder surface, just increases the lift and moves the aerodynamic center forward.
Static and stable layout, when the aircraft is not operating, it can automatically restore the balance, which is safer, but at the same time, such a layout, it also leads to the impossible improvement of the aircraft's mobility, has been restricted, static unstable layout, a small disturbance will be amplified, in this way, the aircraft is quite flexible, but, if people operate, it must be uncontrollable, only the telex system can conquer it, after all, the telex system is faster than the human operation.
Mr. Gu reported the overall thinking, it can be seen that they have done a lot of preparatory work, and today's meeting has indeed opened Qin Feng's eyes, his own Jian-8 must be further upgraded, after all, the No. 10 project is still far away, so the Air Force also attaches great importance to the plan to improve the Jian-8, General Lin listened very carefully there, and even took notes.
Qin Feng's mind is also full of thoughts, yes, these plans are all good, it's just that directly on such a system, Qin Feng has always felt that it is too difficult and the steps are too big.
Mr. Gu should be in a hurry, the entire 601 Institute is in a hurry, the new J-1 project is out of the way with them, for them, this is a heavy blow, so they can't wait to improve the performance of the J-8 and make the J-8 the main force of the Air Force!
This is the sense of competition, so that 601 has a sense of competition, which is rare, they have also changed their thinking, and strive to win the favor of the Air Force, so that they can become a strong shoulder of the Air Force!
When the meeting ended, it was already night, Qin Feng was in his seat, thinking all the time, until General Lin patted Qin Feng's shoulder, he got up, and walked outside with General Lin.
"Do you have an opinion on this plan?" At the debriefing meeting just now, General Lin stopped Qin Feng from continuing to ask questions, until the end, and now, there are two people left in private, and while walking towards the restaurant, General Lin asked Qin Feng a question.
Qin Feng has been abroad many times and has seen a wide range of things, and now that the two are communicating privately, it will not affect anything.
"I think, it's still a bit hasty, in this regard, we don't have any experience, the test flight institute to engage in the stabilizer, is only the first attempt, now, the stabilizer has not yet gone to the sky, here is the three-axis." Qin Feng said: "I'm a little worried, and it's not just the problem of the plane, we don't have qualified test pilots who can fly fly-by-wire control planes." ”
The test pilot is also very important, the control of this kind of aircraft is completely different from the previous one, in case of a situation, how to react? If a test pilot is inexperienced, it is easy to crash.
These are all Qin Feng's worries.
"Yes, that's why Mr. Gu called you in." General Lin said.
Qin Feng was stunned for a moment, Mr. Gu pulled himself in, there was a purpose, this kind of plane, he planned to let himself fly.
Looking at Qin Feng's appearance, General Lin smiled: "We are also preparing, and at the same time, for the new annihilation project, we plan to organize a group of people to go to the West to formally conduct the training of test pilots, and our test pilot system should also be formally established, which is also what you proposed before." ”
Domestic test pilots, without any system, are to catch strong men from the air force units, and then rely on the spirit of fearlessness to test flights, so that it is okay to start, but after entering the third generation of aircraft, it is necessary to have a systematic study of test pilots, need to go to the West to study, and even organize special training classes for test pilots.
Qin Feng nodded: "I applied to sign up." ”
Qin Feng wanted to go, but General Lin didn't agree, Qin Feng went to training, of course, it couldn't be better, but many domestic projects were waiting for him to fly.
"General Lin, Qin Feng, come, sit here." At this time, the two had already walked into the restaurant, and Mr. Gu over there saw it and immediately beckoned them over.
Qin Feng lowered his head, for fear that his grandfather would teach him a lesson, just like a child who made a mistake, but Mr. Gu obviously didn't have this kind of thought, so he beckoned the two of them over, and said happily: "Your eyes are very sharp, and the question is simply to the point." ”
"Grandpa, I..."
Before Qin Feng finished speaking, he was stopped by Mr. Gu, who handed him a steamed bun, and then said: "Chat while eating, I told you before, seek truth from facts, say whatever you have to say, you did a good job." ”
