Chapter 645

It all happened so fast.

Xiang Jing's little Lu didn't have time to pull it out. At the same time, Xiang Jing didn't plan to pull it out.

Will the other party continue to fight? For example, stand up and shoot at your own vehicle with a submachine gun?

impossible.

If they don't hit, evacuate immediately. This is their code of conduct. Delaying is not good for them.

Although there are many people here, it seems that they can provide opportunities for them, but now they throw a grenade, no one can guess their identity. They have enough opportunities to retreat. For example, these parade crowds have been in chaos.

However, if they continue to entangle, it is almost inevitable that their identity will be exposed. In this way, although the Sabbath is now in turmoil, there is no place for them, and even they will lead to unnecessary diplomatic conflicts.

Therefore, they will certainly leave and will not continue to entangle.

Thanks to Lisa, this girl, a girl who doesn't know where to come from, has such a keen reaction. Moreover, how does she know?

The motorcade was next to each other. Qin Guan's car rushed forward. The grenade had been drilled into the bottom of the car. Now, it was a few meters away from the rear car. The fragments of the grenade hit the car's engine and it burst into flames.

The vehicles behind were stunned. The bodyguards pulled out their guns and aimed forward, but they didn't know who the enemy was.

Qin Guan's car turned smartly and returned to the team.

"Protect President Qin!" suddenly, the bodyguards who came with the state of Han protected the car.

At this time, Lisa released the accelerator and handed over the control of the car to the driver. The driver's hands began to tremble.

Just experienced life and death.

"We have called for support, and more guards will come soon." a person in charge of the Sabbath has changed his face, which is a serious event!

Because of its own internal political reasons, it has led to hostility in the whole western world. Now, it is easy for Han countries to be willing to carry out diplomatic exchanges with Sabbath, but they were attacked on the road just after they came to Sabbath.

What does this mean?

It must be the west, especially the eagle country! The eagle people want to destroy the exchanges between Han and Sabbath. If their diplomats are killed, the relations between the two countries will definitely be overshadowed.

Qin Guan sat in his seat and didn't open it. He looked at Xiang Jing, the scholar and Lisa.

Lisa, how on earth did you know there were grenades below?

Xiang Jing and scholar are experienced and rely on a powerful system. What about Lisa? How did she know?

Even if you have many questions in your heart, you can't ask questions now. Wait until you stay in the hotel at night.

Qin Guan restrained his doubts and waited here.

The head of the Sabbath kept apologizing. Soon, he heard a rumbling voice in the sky.

The ground is unsafe. They sent a helicopter!

Qin Guan looked at the helicopter in the sky. It was drooling.

CH-47, zhinugan.

An ordinary helicopter has a large plate on its head and a small vertical propeller behind it, forming a common helicopter structure.

This kind of helicopter is different.

Its body is in a long strip shape, with two large plates at the front and back, and the one at the back is higher. In terms of scientific name, this is called double rotor tandem structure.

The helicopter can take off and land vertically. The key lies in the rotor. The rotating rotor can generate enough aerodynamic lift through the relative movement with the air, so as to achieve the ability of vertical take-off and landing.

However, while the rotor cuts the air to generate lift, it also generates anti torque to the fuselage. If unchecked, the helicopter will spin in the air and cannot fly normally.

Therefore, an ordinary helicopter adds a vertical tail rotor at the tail to eliminate the counter torque of the rotor by pushing air to the side. Therefore, once an ordinary helicopter is hit by the tail rotor, it will spin and fall.

Now, the CH-47 transport helicopter adopts the front and rear longitudinal arrangement of reverse rotors, also known as tandem twin propellers, which is another idea.

The front and rear rotors of tandem Twin Oars are installed on the top of the protruding "Castle", but the rear "Castle" is higher than the front "Castle", so that the front and rear rotors overlap in the horizontal direction and the total length can be reduced. Since both front and rear rotors generate lift, theoretically, the rotor diameter of tandem twin rotors can be reduced by 30% compared with that of single rotor layout, which further contributes to the overall compactness.

Ordinary helicopters should pay special attention when flying. They are afraid of hanging something on the rotor. The smaller the rotor diameter, the more obvious the advantages.

This kind of helicopter is an excellent medium and heavy helicopter. The maximum take-off weight is an amazing 22 tons, which is definitely an adverse figure.

In Qin Guan's eyes, these equipment may enter the sequence of the Han state.

In addition to the zhinugan, there are two tandem two seater armed helicopters, cobra. Under the short wings on both sides of the helicopter, there are also rocket nests, which can destroy the hidden enemy at any time.

The propeller stirred the air flow and made a whirring sound, coupled with the unique roar of the turboshaft engine, formed a symphony. In this sound, the visitors of the Han country stepped on the zhinugan helicopter.

The cabin is wide, and even small vehicles can be driven directly. Now, this special transport helicopter has side wall seats on both sides.

There is still a spacious passage in the middle. Only the side wall seats on both sides can take 33 fully armed soldiers. If more seats are added in the middle of the cargo hold, more soldiers can be taken.

Now, everyone is sitting on the side seat, wrapped in leather, and it's very comfortable to sit up.

The responsible person's face was apologetic: "for everyone's safety, we mobilized a helicopter and flew directly to the government building. Our president is waiting for you in the government building."

Qin Guan sat in the front. The cargo cabin and cockpit were connected. He looked at the two pilots in front of him with interest, drove the helicopter orderly, pulled up and climbed up.

Unfortunately, he didn't bring Chen Rui here. Chen Rui wants to touch anything that can fly. Even a helicopter has a fundamentally different principle from a jet. Chen Rui will be interested.

Well, in addition to the two pilots in front, there is also a flight engineer here. Just talk to him.

Qin Guan winked at the scholar. The scholar understood and took out a gift.
