Chapter 575: The sight is spectacular


On the lawn of the airport, chairs have been prepared, some heavyweights, and telescopes have been obtained. Now, on the runway in the distance, a Tomcat fighter is preparing for takeoff.
Qin Guan didn't care anymore. Sitting at the back, the flight performance of the Tomcat fighter was very good. With the variable swept wings, it had the powerful performance of the entire airspace.
(The previous ones have always been written directly, and some readers may not be very clear. I will give you a brief explanation here.
In the design of aircraft, there is a contradiction that is not easy to overcome: if you want to increase the flying Mach number, you must choose wings with a large sweep angle and a small aspect ratio to reduce the shock wave resistance of the aircraft. Therefore, tell the flying aircraft For example, look at the Civil Aviation Concorde, its wings and sweep angle are very large.
Although it can meet the needs of high-speed flight, this type of wing has low lift, high induced drag, and low efficiency in the subsonic state. That is to say, the performance of low altitude and low speed will be quite poor. This is why many modern fighter jets will be very uncomfortable when playing peekaboo with ancient propeller aircraft.
From the aerodynamic point of view, to meet the aircraft's requirements for supersonic flight, subsonic cruise, and short moment takeoff and landing at the same time, it is best to make the wings swept back and use different swept angles to adapt to different flights. status.
This is the variable swept wing. After decades of development, a practical variable swept wing aircraft was finally designed.
The inner wing section of the general variable sweep wing is fixed, and the outer wing is connected with the inner wing by a hinge shaft. The outer wing is controlled to rotate back and forth through a hydraulic booster to change the wiping angle of the outer wing section and the span of the entire wing. ratio.
In this way, no matter what the state, there is a suitable angle to achieve the best goal, but at the same time, it also has shortcomings, the structure and control system are complex, and the weight is relatively large.
There is only the Tomcat fighter, which uses electronic computer control to automatically change the angle of the swept wings. Many of the others are manually controlled, and the complexity is even higher. )
Therefore, in the future generations, the variable swept wing will be eliminated because it is too complicated, but the performance improvement it brings is obvious to all, such as now.
At this time, in the cabin, the pilot Charlie Brown was doing various preparations before takeoff seriously. With the help of the ground power vehicle, the two tail engines roared in turn.
"Our Tomcat fighter aircraft, relying on variable swept wings, has a very short take-off and run distance. Everyone is optimistic." Here, besides the representative of Han, Kennel is also making an explanation.
While he was explaining, I saw the smooth-looking fighter plane slowly sliding from the tarmac to the runway. Its tail was hot flames, and its wings were stretched. From this angle Look, when the sun shines on the fighter plane, it shows a unique beauty.
Its beauty is different from that of a blue shark. The curve of the blue shark is very smooth, just like a graceful girl. Every curve is so exciting, and the beauty of the Tomcat is mainly its variable swept wings. When it changes, the action is quite chic.
From here, you can see the side of the aircraft. At this time, the flames on the tail of the Tomcat fighter turned into a hot orange-red, and at the same time, the roar of the engine came.
As long as he heard the sound, Chen Rui would know that the aircraft had already opened up afterburner and was about to take off!
Brown in the cabin released the brake, and at this moment, a violent push came from his back.
The Tomcat fighter, as if being kicked hard by someone, and like an off-string arrow, sprinted towards the front of the runway, just with the naked eye, you can see its rapid acceleration.
"That's not right." Chen Rui muttered in his mouth suddenly.
Of course something is wrong. Chen Rui flew this aircraft on a flight simulator. It is no problem to say that it is the best of the three generations, but it is wrong to say that it accelerates so fast.
Because the engine of this kind of aircraft is not powerful, the thrust-to-weight ratio of the whole aircraft drops to a pitiful 0.7 after being filled with fuel. How can it roll so fast?
In his suspicion, the entire inspection group had already let out a loud exclamation.
The front wheel of that Tomcat fighter has been raised!
Many of the people present had watched previous F-16 flight demonstrations, and were shocked by the speed of F-16. At this time, I didn't expect such a big fighter plane to be so powerful!
Even more powerful than F-16!
The front wheel was off the ground and it continued to roll forward for a few seconds, and the rear wheel followed up. At this time, its entire running distance was at most two hundred meters!
In contrast, look at the fighters of Han, J-7 and J-8. Without a runway of more than one kilometer, they can't fly at all!
What is the use of the running distance?
When the war comes, the airport is definitely the enemy's first target. As long as the taxiing distance is short enough, as long as there is a section of the runway that can be used, the fighter plane can take off!
The short-range take-off capabilities of the three generations of aircraft are quite excellent, but if you can say that you can take off less than 200 meters, this is definitely the only Tomcat. This is the advantage of variable swept wings.
When the wings are deployed, it has excellent take-off and landing performance, which is incomparable to a fixed-wing aircraft. It is the advantage of the variable swept wing brought out of the tyre.
However, if only relying on the variable swept wings to be so powerful, then Qin Guan absolutely didn't believe it.
It seems that they are using the same set of the king of Huyou's kingdom, and um, in a moment, do you want to dismantle them?
While thinking about it, Qin Guan saw the Tomcat fighter spread its wings and began to take off at a high angle of attack.
"It's beautiful, it's so beautiful!" Suddenly, someone in the Air Force sighed continuously.
I've seen the F-16 take off at a high angle of attack before, and the Tomcat fighter takes off at a high angle of attack, which is even more spectacular. It spreads its wings, like a proud goshawk.
Even Qin Guan sighed for this shot, beautiful is beautiful, and he admits that in later generations, he has seen the lofty ambitions countless times, and he was upset because of Tomcat's retirement.
Although it was obtained by cheating, it is really beautiful.
Looking at the expressions of these people, Billworth was excited in his heart. It seemed that the plane had successfully aroused their interest. It seemed that he was one step closer to success.
The next scene will be more exciting, the backward Han Air Force, see the true power of the Tomcat fighter!
Billworth was very excited. If even fifty were sold this time, Grumman would make a fortune.
