Chapter 1047: No matter how difficult

Yun Shi parked quietly on the tarmac of the airport, as if waiting for something, Qin Guan walked up, walked along the passage to the front, and then sat on the flight seat.
The driving of a passenger plane is different from that of a fighter plane.
Chen Rui was flying a fighter jet, and now he was seated in the seat of a passenger plane, next to Qin Guan, and said: "This kind of big plane, if you want to test flight and spin, you must be cautious."
Chen Rui is not afraid of death, but he knows that he can never do it recklessly.
The horse behind always stood and said to everyone: "Yes, of course we know that we can't do it recklessly. If you want to test the tail spin of a passenger plane, it is best to have an anti-tail parachute."
The anti-tail spin umbrella, also known as the tail spin-out umbrella, after the tragedy of the Niu Guo passenger plane appeared that year, they conducted a careful analysis.
After investigation, they found that the aircraft entered a phenomenon called "deep stall" at that time, which was brought about by the high T tail configuration. When the angle of attack of the aircraft reaches a certain level, the horizontal tail fin enters the shelter area of ​​the wing and loses its effect. The original way to recover from the stall spin was to make the aircraft lower its head and accelerate, and the horizontal tail of the aircraft was rendered ineffective, making this phenomenon unsolvable.
So, what should we do in this situation? For mature models, its stall boundaries will be explored by test pilots. When the aircraft approaches these boundaries, the flight control system will remind the pilots, or directly take over the control to prevent the aircraft from stalling.
Therefore, a normal flying aircraft does not have to worry about entering a spin, but the test pilot is here to explore the boundary conditions of the new aircraft.
Therefore, this kind of anti-tail umbrella was invented.
In the tail spin, since the speed of the airplane is relatively slow, the movement of the airplane is mainly based on rotation, and the ability of the airplane to change state is small. However, the airplane needs considerable force to recover from the spin.
After the aircraft is equipped with an "anti-tail spin parachute", when the pilot cannot recover from the tail spin normally, the aircraft can open the "anti-tail spin parachute" through the launch button in the cockpit.
At this time, the "anti-tail parachute" installed on the tail of the aircraft will be taken out by the small rocket. After the "anti-tail parachute" is opened, it will generate a lot of traction, instantly change the air attitude of the aircraft, and directly move the aircraft from the tail. "Pull out" while spinning.
This is the principle of the anti-tail parachute. It is somewhat similar to the airplane's deceleration parachute, but it is more aerodynamically efficient, more robust, and has a particular location.
Without this set of equipment, it would be difficult to transport the ten test spins.
Qin Guan heard Ma's words and asked, "Then, has our anti-tail umbrella been researched out?"
Old Ma shook his head: "Spinning is a difficult subject in the aviation industry. We have done very little research in this area. As for passenger aircraft, we have never done it. Therefore, it is a blank now."
Without the anti-spin umbrella, the tail spin test flight is doomed to be full of risks, which is why they are hesitating and have not had a test flight.
"Well, let us solve it." Qin Guan already had an idea, and went to the weapon material cemetery to find the anti-tail umbrella of this large aircraft.
Yunshi is a copy of Boeing 707, so go to the test flight data of Boeing 707 and find the subject of its tail spin test flight, naturally there will be such a thing.
Although the Boeing 707 is a civil aviation airliner, it has many military aircraft modifications. It should be considered in the weapon data cemetery. If not, there are new transport aircrafts and bombers of the same kind. In short, you can find them. Of it.
Qin Guan made up his mind. In short, no matter how many difficulties there are, he must continue the project.
Moreover, once the transportation is successful, can it be converted into an aerial tanker, can it be sold to the Kingdom of Parth? Or exchange with the plane of the Shabbat?
This thought flashed past, let's talk about the future things, and do the present now.
The information can't be taken out immediately. Let Chen Rui familiarize himself with the operation of Yunshi in the past few days. When he is all familiar with it, the information is also obtained, and the anti-tail umbrella is installed, then the test flight is much easier.
"Our big airplanes are still blank. If there is a flight simulator for big airplanes, it would be great." Chen Rui said suddenly.
Hearing Chen Rui's words, Qin Guan suddenly started. Yes, he simply exchanged another flight simulator. In this way, the subject of stall and spin can also be tested on the flight simulator now!
This greatly reduces the risk. Although there is no transportation data in the flight simulator of the passenger plane, there will definitely be the Boeing 707.
Qin nodded his opinion: "Let our technicians find a way to build this kind of flight simulator for large passenger aircraft!"
After inspecting the passenger plane, the flight test subjects of the J-8-2 and J-11 fighters have also been completed. The two planes flew over one after another, and even one landing seemed to be in competition.
Qin watched it amused, but the research and development of military aircraft must be like this. If it can compete, it will naturally be the best.
After dinner, in the afternoon that day, Air Force Commander General Zhang arrived with a crowd of people.
The Tomcat fighters make the air force even more powerful. The J-11 fighters developed on the basis of the Tomcat fighters are even more valued by the air force. After all, Han is a vast country, relying on the seventy Tomcats. Fighters are far from enough. It can even be said that this batch of Tomcat fighters is just a seed, allowing the country to quickly move in the direction of three generations of fighters. However, if they want to bear fruit, they have to rely on their own efforts.
This is the meaning of J-11.
At the same time, thanks to the contacts of the 6601, such an improvement of their J-8-2 fighters has naturally been sought after by numerous people.
Every once in a while, the senior air force would come here to take a look at the progress of the research and development of these fighters. Now, the test flight is the last step towards success, and it has attracted everyone's attention.
"General Qin, let's meet again." General Zhang said, holding Qin Guan's hand enthusiastically. Qin Guan's contribution to the Air Force is obvious to all.
"General Zhang, I am so happy to see you." Qin Guan said: "I am also proud of the progress of our air force equipment. We have to close the gap with the West on the third-generation aircraft. By the fourth-generation aircraft, we can achieve catch-up and overtake. Up."
At present, the third-generation aircraft in the West have only just been equipped with troops. For example, the Eagle Country’s F-15 is now overcoming the technical shortcomings of the advanced F100 engine and is truly maturing. It can be said that it has caught up.
By the fourth generation of aircraft, it will have to catch up.
Fourth generation machine? Hearing Qin Guan's words, everyone was taken aback.
