Chapter 155: Air Show
Because the M-53 engine is a single-rotor engine, the thrust-to-weight ratio is not high, so the climbing ability of the Mirage 2000 is not outstanding, the aero engine has always been the industrial peak of the Everest, involving materials, processing, design and other links, the French aviation industry can develop this turbofan engine on its own, has done its best. But this engine also has advantages, high reliability, simple structure, and low maintenance costs.
Therefore, on this flight, Bill also cheated slightly, he only carried fuel for the air show, and there was not a drop of fuel in the huge wing fuel tank, only some fuel in the fuel tank in the fuselage was able to make the chic take-off maneuver just now. Moreover, this is a testing machine, with no other equipment installed, and its own weight is very light.
At an altitude of 1000 meters, Bill leveled the fighter, and the air show officially began.
The Mirage 2000 uses a huge delta wing structure with a very large wing area, resulting in a rather small wing load, even under combat weight conditions, the wing load is only 234 kg/m². Even in the afterlife, it is very small, and its usable lift is relatively large, so it can be very good to circle instantaneously. It has a maximum instantaneous angular speed of 30 degrees per second.
Bill's first performance is the most prominent Mirage 2000 surname can horizontal roll and horizontal figure 8 flight.
"Attention, the plane is coming." The narrator explained next to the delegation.
The people below looked and saw that the plane that had just flown out of sight was flying rapidly from the left.
Bill glanced at the airspeedometer, the speed of 400 knots was just right.
With the rod in his hand, Bill began to expertly push to the right.
Suddenly, the sky began to rotate in view, the horizon on the left disappeared, and the plane began to roll horizontally.
If it was an untrained person, I am afraid that he would already be dizzy at this time, but Bill's brain was extremely clear, he looked at the outline of the earth above his head, which had turned one hundred and eighty degrees, and then saw the horizon on both sides of the wing, and completed a three hundred and sixty degree roll, but he did not give up, and the hand holding the bar did not let go until the plane turned three times and completed three rapid rolls.
Bill then pushes the rod in the opposite direction and starts rolling in the opposite direction again.
The people on the ground were amazed to see the fighter in the sky like a skilled little fish, happily moving forward and rolling at the same time, which was very exciting, and they couldn't help but applaud.
Even Sarah and Prince Waleed, who were mixed in the inspection team, were infected by this wonderful action.
The layman looks at the excitement, the insider looks at the doorway, especially Reyer, who is even more shocked, he never dared to do such a fast roll when flying the MiG-25, otherwise, there is only one result, the steel structure of the MiG-25, will not be able to withstand the huge overload, the air disintegration.
After the roll was completed, the plane had already flown over the delegation.
Bill pushed the lever to the right again and kicked the rudder on the right. This time, the plane made a quick turn to the right, and in just one second, it had achieved the expected angle, and then, in the opposite direction, began to fly inward again.
The expedition group on the ground raised its head and looked at the planes in the sky like a dance, drawing a beautiful figure-of-eight.
It's a pity that it's not a performance machine, if you put on a special smoke canister and pull out the smoke canister when flying, then a beautiful pattern will appear in the air, Zhang Feng thought to himself.
At this moment, Bill in the sky feels that he is completely integrated with this fighter, he likes to fly, he likes the blue sky, and he likes this good horse under his crotch.
After flying the figure-eight and leveling the plane, Bill turned on the afterburner switch again, and then, pulling the longitudinal rod backwards, the fighter flew upwards at a right angle of almost 90 degrees.
This flight startled Zhang Feng, and Reyer and Arslan next to him were already dumbfounded.
Could it be that the M-88 has already come out in advance? The M-53 equipped with the Mirage 2000 is simply not enough to provide a thrust-to-weight ratio of more than 1, which is a prerequisite for being able to climb vertically effortlessly! Only the Mirage 4000, equipped with twin engines, can easily perform this action.
Vertical climbing is a move that Reyer and Arslan want to make in the sky very much, but the bulky MiG-23 piloted by Arslan is not even imaginary.
Later, however, several people saw that as it climbed, its speed began to decrease.
That's pretty much it, otherwise, the Mirage 2000 would be too perverted.
Bill just wanted to perform beautifully, so he turned on the afterburner and climbed to a height of 1,500 meters.
As soon as Bill pushed the lever, the nose of the plane turned down again and began to dive at high speed.
The following action is called stall tailspin and changed!
It is very difficult to get the fly-by-wire fighter to make a stall tailspin maneuver, the computer will control the fighter to avoid entering this dangerous state, and, even if it does, the fly-by-wire system can change it on its own.
The fly-by-wire system has a very advanced place, if the pilot has a space obstacle, I don't know whether he is flying forward or backwards, (this is also the reason for the crash of some fighter jets, such as flying upside down on the sea surface, as a result, the blue sea water as the sky, and then a push rod climbs, pierced into the sea water), and even the pilot has a fainting, as long as the hands and feet leave the pole, the plane will change back to level flight by itself.
"That plane is going to fall!" Suddenly, there was a panic in the crowd.
I saw that the fighter in the sky, while spinning, quickly fell from the sky, yes, definitely fell vertically.
Just now they flew up vertically, and no one was afraid, but now that they have fallen, they are a little afraid.
If the plane had fallen into the crowd, they would have all been buried here.
"Don't be afraid, it's a stunt event called a stall tailspin." The narrator said.
Sure enough, when it was still two hundred meters above the ground, the fighter stopped its madness just now and changed to level flight as if it had been subdued.
"Your Excellency Qusay, our fighter has a good surname, right?" Boileau said with a smile on his face.
Hearing Sarah's translation, Zhang Feng replied: "Very good, the surname can be advanced enough." ”
"In the evening, we will hold a cocktail party at the flight test center, and I hope that friends from the Middle East can participate together." Boileau said: "Mr. Dassault will be there then. ”
Looking at the Mirage 2000 in the sky that was passing through the field at low speed, this was the last action, showing that the Mirage 2000 had outstanding low-speed surname ability, Zhang Feng said: "It's a great honor to meet Mr. Suo. ”
ps: Thank you for the book friend who is too tired to tip!
