Philip is also introducing the design features of the M30 transport aircraft to Hitler and his two henchmen, as well as Dai Yulong and Bai Wanrou, Hitler is okay, he has seen the M30 business transport plane yesterday, but it is static, he is also full of interest in the upcoming air show, and Dai Yulong and Bai Wanrou They are the first time to see such a large plane for a flight show, not to mention the excitement in their hearts.

I saw that the four pilots were divided into two groups, and walked to the two M30 business transport planes on the runway, and when they got into the cockpit, they quickly started the engines, and saw that the engines of the two M30 business transport planes began to roar, and the six-bladed propellers also began to accelerate and rotate, and the air around the engines was pushed behind the propellers, making a buzzing sound.

The pilots of both crews waved to the audience through the glass on the side of the cockpit, which drew a chorus of applause from the audience. Soon, under the strong impetus of the engine and propeller, an M30 in front began to slowly glide forward, and an M30 business transport aircraft behind it pulled away, and then began to accelerate and run, the audience was even more excited, because they could immediately see the moment when the plane took off, many spectators have not watched the plane take off so closely, and these two M30 business transport aircraft can be regarded as large planes in this era.

Philip began to introduce to Hitler and others around him: "Our M30 business transport aircraft has a very good ability to take off and land over short distances, it can even take off and land on simple dirt runways, and its take-off and running distance is only more than 300 meters, you can see it immediately." ”

As soon as Philip's voice fell, the first M30 business transport plane had already left the ground with its front wheels raised, and it was about to take off, and then the M30 business transport plane behind it also began to accelerate and run, with a distance of only more than 200 meters before and after, which made the audience very enjoyable! This scene of two-plane take-off is not so easy to see, even Hitler stared intently at the two business M30 transport planes on the runway, and this big man also saw such a business transport plane take off in two planes for the first time.

As soon as the first M30 transport aircraft broke away from the constraints of the ground, it came to a large angle of attack climb, from the ground, the elevation angle of the aircraft was soon close to 70 degrees, and it looked like it was going on a vertical ascent.

"Oh my God, am I dazzled? Why does it look like the M30 is flying vertically? It's incredible! ”

"I didn't expect a transport plane to fly like this! Look, the second M30 transport plane also took off, and it still climbed at the same large angle, which is really exciting! ”

……

The audience did not hesitate to praise the shocking take-off picture of the M30 business transport aircraft with the most beautiful words, and even Juncker and other aircraft design masters had to admit that the aerodynamic design of the M30 business transport aircraft was too successful, and this kind of large-angle climb is not something that ordinary aircraft can do, even if it is a fighter who is good at maneuverability, there is a great risk when doing this kind of flight maneuver, because the flight at a large elevation angle is very easy to make the aircraft enter a stall state. The fact that the pilots of these two M30 business transport aircraft dared to take on such a high-risk subject without a single accident shows that the aerodynamic design of this aircraft is very successful, and the pilots have strong confidence in this kind of aerobatics.

Hitler also exclaimed: "Oh my God, Mr. Philip, your pilots are flying the M30 business transport plane as if it were a fighter jet!" Such a bold flight maneuver is not something that can be easily tried even on a fighter, or you are amazing! ”

Bai Wanrou asked curiously, "Mr. Philip, why is everyone saying that the take-off of these two planes is incredible?" Can you tell us about it? ”

Philip nodded and said, "Yes, the large angle climb of the aircraft is a high-risk flight subject. From the perspective of the aerodynamic principle of the aircraft, the elevation angle of the aircraft is large enough to a certain degree of airflow separation, resulting in greater pressure on the wing than below, and a decrease in the lift coefficient, resulting in a stall. Flying at large elevation angles places high demands on the aerodynamic layout and engines of the aircraft. When this airflow separation develops to a certain extent, the aircraft will shake, and the heavy shake vibration will have a serious impact on the handling and stability of the aircraft, and there will also be loss of control phenomena such as upward tilt, wing shaking, wing downstroke and nose deviation, and even entering tail spin. In aviation terminology, the elevation angle is generally called the angle of attack, also known as the angle of attack, which refers to the angle between the wingchord and the airspeed of the aircraft. At the same airspeed, the greater the angle of attack, the greater the lift, and at the same time, the greater the drag. However, the angle of attack is not always positively correlated with lift, when the angle of attack exceeds the critical value, the upper airflow of the wing appears turbulent, the laminar adhesion layer disappears, the drag increases, and the lift decreases, which will cause a typical large angle of attack stall, and even the aircraft will enter a tailspin. Under normal circumstances, the angle of attack of an aircraft is limited to less than 30 degrees, and in special cases it does not exceed 50 degrees. However, our M30 business transport aircraft benefits from good aerodynamic design and excellent propulsion system, so it can achieve a high angle of attack climb close to 70 degrees in this unloaded state. ”

When Philip finished explaining the knowledge of large-angle climbing to Bai Wanrou and others, the two M30 business transport planes in the air showed off their maneuverability again, causing the audience to exclaim one after another! Seeing that the two M30 business transport planes showed their high angle of attack flight ability to the audience, they turned into a large slope circle, and then entered a level flight state. After the two planes formed a double formation in the air, another flying stunt came that surprised everyone.

The one numbered No. 01 of the two M30 business transport planes, the wing on one side suddenly sank, and then the whole plane flipped one hundred and eighty degrees around the axis of the fuselage, entered the upside-down state, and just under the belly of the No. 02 plane, the two M30 business transport planes came to a belly-to-belly stacked Arhat flight, this scene is really spectacular. Although the distance between the two planes up and down is actually forty or fifty meters, from the ground, it looks as if the bellies of the two planes are close together, and this stunt is even more shocking than when they took off just now! Because from the perspective of perception, the two planes are so close to each other that a slight mistake may collide, and then there will be an accident in which the plane is destroyed and people are killed, and the business transport plane is used to fly upside down, which is not something that ordinary people can imagine, so this flight stunt looks thrilling and exciting, and the audience screams from time to time, and many viewers are so frightened that they reach out and cover their mouths.

Although Hitler was also shocked in his heart, he did not show it, and his emotional control was very strong. The same is true for his two subordinates, but Dai Yulong and Bai Wanrou are different, where have the two of them seen such a flight show, Dai Yulong's eyes widened, and his expression was in disbelief. Bai Wanrou let out a coquettish cry, stretched out her jade hand to cover her mouth, and at the same time moved her gaze to Philip.
