Watching the flying leopard rush into the blue sky, people were boiling.
The two top test pilots continued to maneuver the Flying Leopard to increase the altitude, and it actually flew at a high angle of attack, which is really bold, you must know that this is still an unshaped fighter.
People couldn't help but sweat for the test pilot, if it was an accident, there was a possibility of accidents, but fortunately, the Flying Leopard fighter did not disappoint people.
Then it performed a maneuver over the blue sky and a maneuver with a steep slope.
However, after all, this is a fighter that is still in test flight, so its performance time is not long, that is, after about ten minutes, it will drop altitude and land.
Just after the flying leopard performance, the next one on the field is the Chinese Air Force Bayi Air Show Team, seven blue and white painted J-7 performance aircraft took off from the runway in turn, and then quickly completed the formation, and then their performance is also amazing, like what five aircraft flower, two planes flying head-to-head, etc., every action is very ornamental, but also very thrilling.
This is the first appearance of the Bayi Air Show Team after the newly redressed, so both media reporters and professional enthusiasts have pointed their long and short shots at them.
Just after the Bayi Air Show Team completed the wonderful performance, the next air show was wonderful, only to see two antique planes, that is, the kind of biplane aircraft during the First World War, taxied onto the runway.
And the most surprising thing is that there are beautiful women in bikinis on the plane, and at this time the professional audience knows that the most thrilling show at the air show is about to begin.
After a while, the beauties will climb out of the cockpit and stand on top of the biplane.
Imagine how bold it must be to dare to go on, not to mention that it is still a beauty.
This is the Breitling Wingwalk Show Team from Europe!
In the eyes of the audience, two antique biplanes slowly flew into the sky, and then two bikini beauties climbed out of both planes, only to see that they boldly climbed to the left and right wings, and then there was a series of ballet movements, sometimes lower waist, sometimes raise legs, sometimes stand up, sometimes take off in the air, and perform parallel to the fuselage to show swallow balance.
Lin Miaoyu was so frightened that she grabbed Shen Huan's arm tightly and screamed: "It's so scary, how can such a performance not be forbidden!"
What if you fall down?
” Shen Huan hurriedly explained: "Punch words, don't worry, they're fine."
Haven't you heard of this acting team?
They are the famous European Breitling wingwalkers.
This is a special kind of performance, which originated in World War I, when an airplane broke down and the fighter plane was in flight, and the pilot had to climb out to repair it, and then it gradually evolved into a performance.
Rest assured, because these biplanes are very slow, they are professionally trained and will not have problems. ” Despite this, the audience screamed from time to time, and when the beauties finished their wonderful performances, the crowd erupted in thunderous applause and cheers.
After the two biplanes landed, the audience had not yet recovered when a huge passenger plane slid towards the runway.
It's a huge plane, with a fuselage length of over sixty meters, as well as a wingspan, and of course the most striking thing about the two huge turbofan engines hanging under its wings.
Such a big plane, just relying on two engines to fly, how amazing is the thrust?
In fact, the huge engine under the wing of the Airbus A330, whether it is the CF6 series produced by General Electric, or the Rolls-Royce Turbulence 700 is a large bypass ratio turbofan engine with a thrust of more than 300 kN, which is the goal that China's aviation industry has always wanted to catch up, and China's aviation industry is indeed too far behind in the field of aero engines.
Not to mention that such a high-thrust turbofan engine, even the turbofan nine used by the flying leopard has not yet been completely localized, and it is still working hard!
Of course, Shen Huan also understands that all this will take time, and China will definitely catch up in another twenty or thirty years, and the future C929 wide-body passenger aircraft will use a domestically produced high-thrust turbofan engine.
The appearance of this Airbus A330 also caused a cheer, such a large passenger plane for a flight show, the visual impact must be quite shocking!
At this time, the pilot on the Airbus A330 also opened the gunhole on the side of the cab and waved to the audience, it seems that they are very confident.
As the two high-thrust turbofan engines under the wings of the A330 passenger plane began to emit a powerful roar, its huge fuselage began to accelerate forward, and the air flow from the powerful engine was also long.
After taxiing for more than 1,000 meters, this large passenger plane also suddenly pulled out onions on dry land, the nose was held high, and under the impetus of two powerful turbofan engines, its huge fuselage actually came to an almost vertical climb!
The visual impact is truly impressive!
Such a large passenger plane can climb vertically like a fighter!
The audience also let out a burst of exclamations.
Lin Miaoyu also said in surprise: "Shen Huan, how is this possible?
Can airliners also climb vertically?
” Shen Huan smiled and said: "This is not a real vertical rise, at most it is more than sixty degrees, it is mainly due to visual errors, which makes people look like a vertical rise."
Theoretically, as long as the thrust-to-weight ratio of the aircraft, that is, the ratio of the maximum thrust of the engine to the weight of the aircraft, is greater than one, the aircraft can climb vertically, so in the air show, we can often see the vertical climb of the fighter, that is because the fighter is no-load and half-fuel, the thrust-to-weight ratio is generally more than one, for example, our flying leopard, the thrust of its two engines adds up to more than 18 tons, and its weight in the semi-oil state is less than 18 tons, so it can be vertical. ” Lin Miaoyu asked: "What about this Airbus?"
” Shen Huan smiled and said: "In the case of normal load of passenger aircraft and transport aircraft, the thrust-to-weight ratio is generally only about 0.2, but the performance aircraft are not loaded, and only a small amount of fuel is added, so the thrust-to-weight ratio will reach about 04, and the two turbofan engines of Airbus A330 under the wing are as turbulent as 700 tons, with a maximum thrust of more than 30 tons, and the two add up to 60 tons, and its empty weight should be a little more than 100 tons, and the thrust-to-weight ratio is also 0.5, so it can climb at an angle of attack of nearly 70 degrees.
From the viewer's point of view, it looks like a vertical climb, but in fact there is a certain angle from the vertical climb.
The real vertical climb, the wing does not produce lift, generally only the thrust of the fighter with a relatively large weight can do, like passenger aircraft and transport aircraft, this action is actually a large angle of attack climb, it still relies on the wing to produce part of the lift, of course, this is also a kind of extreme challenge, if the thrust is not enough to pull hard, the plane will stall and then fall. ”
