Philip smiled: "You don't need to panic, this aerobatic maneuver is just a piece of cake for our pilots and M30 business transport aircraft, there will be more exciting maneuvers in the future, you just wait and see." ”

Bai Wanrou was shocked, took the jade hand away from her mouth, and said: "Mr. Philip, the plane can still fly upside down, this is the first time I have seen it, I have never even heard of it before, what is going on?" ”

Philip smiled: "In order for the plane to fly upside down, two must be met, first of all, the plane can only fly upside down if it has an inverted fuel tank, if the plane can only rely on gravity to transport fuel when flying upside down, the aircraft engine will stop due to lack of fuel and crash." There is a valve in the inverted fuel tank, when the normal flight, there is fuel in the inverted mailbox, which can be used to fly upside down for a short time, and when the aircraft resumes level flight, the valve of the main fuel tank and the inverted fuel tank is opened by using the principle of gravity, and the valve is closed after the fuel enters the inverted mailbox full. The plane can fly upside down again, and so on. The lubricating oil system is controlled by the lubricating oil pump to work, so there is no difference between flying forward and backward. Secondly, the airfoil of the aircraft should be able to produce lift on both sides of the front and back, and either side can generate lift with the support of the flaps, which is enough for inverted flight, otherwise the aircraft will crash due to the loss of lift when flying upside down. Our M30 business transport aircraft uses a pressure fuel delivery device, so it can fly upside down, ordinary transport aircraft cannot, and there is no need to fly upside down in addition to performance. Well, everyone, look, more exciting shows are about to begin! ”

As soon as Philip's words fell, the No. 01 M30 business transport plane in the air in an upside-down state made another amazing flight maneuver! The audience couldn't help but applaud the aerial ballet of the two M30 business transport planes!

I saw that the No. 01 M30 business transport plane suddenly changed its flight status, from flying upside down against the belly of the No. 02 M30 business transport plane, to entering a spiral flight around the longitudinal axis of the No. 02 M30 business transport plane, and it was also very close to the No. 02 M30 business transport plane, only forty or fifty meters. From the ground, I saw that the No. 01 M30 business transport aircraft was like a butterfly wearing flowers, up and down, showing the flight performance of the M30 business transport aircraft to the fullest! Where have the spectators seen such a wonderful air show, the whole square is boiling, and many people let out bursts of boos. Some even whistled to express their praise for the air show!

The reporters of the news media even focused their cameras on the two planes and kept pressing the shutter, for fear of missing the wonderful scene in the sky. Those professionals of aircraft manufacturers can't help but gasp, as the saying goes, the layman looks at the excitement, and the insider looks at the doorway. As professionals, how can these people not see that the performance of the M30 business transport aircraft is too good. Not only is it a cost-effective commercial transport aircraft, but it also reflects how high the level of its design and manufacturing company is, at least so far, except for the Dragon Soul Ordnance-Industrial Complex, no aircraft design and manufacturing company has been able to make such an aircraft.

Juncker muttered while watching the wonderful air show: "It seems that our Junkers company has lost unjustly, and the M30 business transport aircraft is indeed a big cut better than our Ju52/3m transport plane!" ”

Vincent, who was on the side, sneered: "Mr. Juncker, I don't think this M30 business transport plane is anything remarkable. These are just fists and legs. Are these flight maneuvers necessary for a transport aircraft? If the plane flies like this. Can the passengers inside stand it? So it doesn't make any sense at all! ”

Juncker just glanced at Vincent, but didn't say anything, because he didn't bother to say anything to this man. Vincent also seemed to know that he was not very popular, so he pretended to look at the crowd to avoid the awkward atmosphere.

The M30 business transport plane continued to enter the state of two-plane formation level flight, made a detour in the distance and flew back. Then they made an even more amazing move, especially for the female audience, who enjoyed a romantic air show.

I saw a puff of white smoke suddenly coming out of the tail of the two M30 transport planes, and the audience who didn't know the reason was frightened again, including aircraft designers like Juncker, who didn't understand what was going on. However, the professionals are much better than the average viewer, after all, they can also see that it is not a malfunction of the plane, but a device that can release smoke has been specially installed.

The next flight was even more unexpected. The two M30 business transport planes pulled the white smoke, and suddenly separated to the left and right, and they both made a big gradient jump, and then the plane flipped 180 degrees along the longitudinal axis, turning the belly diagonally upward, and the plane diagonally downward, making a somersault flight maneuver. The flight trajectory of the two M30 transport planes in the air was all drawn by the white smoke pulled out of the tail, and the attentive female audience had already seen that the two white smoke had drawn half of their hearts in the air, so they almost guessed the next flight trajectory of the two M30 business transport planes.

Sure enough, after the two M30 business transport planes completed the somersault, they continued to fly along this arc flight trajectory, turning into a pair of planes flying head-to-head cross, although the flight speed is not very fast, but this head-to-head cross flight still looks very thrilling! If there is a slight mistake, there is a possibility that the two planes will collide. Of course, the distance between the two planes in the air is not actually as close as it seems on the ground.

In the exclamation of the audience, two M30 business transport planes whizzed past each other, drawing a big heart shape in the air! After completing this action, the two M30 business transport planes swooped down, and they were about to collide with the ground, and the audience broke out into a burst of exclamations, this scene was too thrilling, and the continuous thrilling actions made the audience, especially the female viewers with poor psychological tolerance, frightened.

Just when the two M30 transport planes dived downward, and the nose of the plane was less than 100 meters above the ground, the plane finally began to prepare to pull up, and the plane drew an arc in the air, and when it reached the lowest point, the two M30 business transport planes were only 30 meters high from the ground, and finally pulled up and jumped into the air again.

Hitler was also fascinated by it, he did not expect that the transport plane could make such a thrilling flight maneuver, the future German Führer also studied airplanes, but today's air show was obviously beyond his imagination, and now he is even more interested in Philip, such talents are not used by him, obviously not Hitler's style.

The two M30 business transport planes finally came to the field at a low altitude and low speed, flying at a low speed of less than 10 meters over the temporary runway, during the flight, the two M30 business transport planes invariably shook their wings up and down to greet the audience. The enthusiasm of the audience is undiminished, and they applaud loudly at these two planes, today's air show is unforgettable for every audience, they are glad in their hearts, they did not miss this defense exhibition, otherwise I don't know how much to regret!

After completing the low-altitude and low-speed passage, the flight show is over, the two M30 business transport planes are aimed at the runway one after the other to land easily, even at this time they do not forget to show off the landing performance of the aircraft, the two M30 business transport aircraft are brakes and anti-propellers are used together, the landing and running distance is shortened to more than 200 meters, once again showing its excellent landing performance.
