The 8321 is a sixteen-pin chip, and having four outputs is not much. Pen, fun, pavilion www. biquge。 But for Ding Chen now, it is not easy to figure out what these four pins do.

Stepper motors are controlled by electrical impulses and require fairly precise means of control. This is simply not possible by manually lowering the pins.

This also means that if Ding Chen finds out that he has made a mistake, he will not even be able to recover it as it was.

So Ding Chen hesitated for a moment, turned his head to look at Ding Chen, and asked, "What are the other three outputs for?" ”

"It's a vector engine." Ding Chen said coldly: "What do you think? ”

Ding Chen sighed and raised the tool knife in resignation, "It seems that we can only gamble on luck." ”

"We had a lot of luck." Ding Chen was still in the mood to tell jokes at this time, "At least we are still flying in the sky." ”

Although Ding Chen was in a very bad mood, he still couldn't help but glance at him, "Your comfort is really reassuring." Then he poked the tool knife folded into a V-shaped tool into the chip pins and immediately lifted it up.

The operating voltage on this chip does not exceed five volts, so the operation of Ding Chen does not bring any visual effect. Then the two of them felt that the shuttle in them seemed to vibrate, and their bodies involuntarily leaned to the side.

The two of them glanced at each other, and Ding Chen frowned and said, "Posture adjustment." ”

"We're turning left." Ding Chen also judged.

"Great." Ding Chen said: "We need a high level. ”

"Use the fifth kick." Ding Chen said: "This one is closer. ”

Seeing that Ding Chen was about to recover the direction of the vector nozzle, Ding Chen suddenly said, "Wait a minute." ”

He looked at Ding Chen and said, "If we turn back, maybe it's not a bad idea." ”

Ding Chen understood in seconds and felt that he was right. So instead of trying to resume the operation just now, I changed the output and continued to lower the level.

This time, he didn't feel any change in the flight attitude of the shuttle, and he couldn't help but feel apprehensive. The two of them waited in silence for a while, and Ding Chen frowned and said, "I didn't expect our luck to be so good. ”

"You can press it again, this time for a little longer." Ding Chen suggested: "Reduce the speed to a minimum. ”

Ding Chen nodded. Slowing down in the sky isn't necessarily a good idea, but sustained acceleration consumes a lot of fuel, and now they need time to think about what to do.

He lowered the pin again, this time for a little longer than before. So both of them felt the shuttle vibrate slightly, and then the body tremor caused by the constant acceleration just now disappeared.

Both nervous men laughed, and it was clear that they had succeeded. Ding Chen listened to the noise of the ramjet engine sideways, frowned and said, "Is this sound normal?" ”

"I'm an electrical engineer." Ding Chen said, "How can you expect me to be able to hear if this thing is normal? ”

Ding Chen raised his eyebrows, and was about to remind Ding Chen that his voice was too loud, but he suddenly realized that it was not Ding Chen's voice that became louder, but the noise around him disappeared.

He was taken aback and immediately turned his head to look in the direction of the engine in the tail of the shuttle. Ding Chen had already realized the same thing at this time, and almost turned his head with him, and then the two of them were sure of the same thing - the engine stopped working.

For a vehicle that is still in the sky, losing power can almost be equated with disaster. So Ding Chen immediately turned his head to look at the electrical control box next to him, but found that the two relays were still in the closed position, obviously not because of the control system.

He turned his head to look at Ding Chen and asked hopelessly, "Do you know what happened?" ”

"I guess." Ding Chen said slowly: "We have no fuel. ”

That's a reasonable guess. Although the shuttle plane that Ding Chen and the others took was relatively luxurious, it was not luxurious enough to prepare for an intercontinental trip. After flying at maximum thrust for so long from the start of takeoff, it is clear that the fuel carried should also run out.

When the two men emerged from the baggage compartment, they were warmly welcomed by the others. Everyone already felt that the shuttle was slowing down, so it was natural to think that it was the credit of Ding Chen and the others, and when they saw the two people coming out of the luggage compartment, Ding Chen's sister immediately ran over, hugged her brother, and shouted, "You succeeded." ”

Ding Chen shook his head and did not speak. When the others saw the serious expressions of the two people, they realized that the situation was worse than they had imagined. Leng Yue frowned and asked, "What happened?" ”

"The engine stopped working." Ding Chen said: "It is likely that there is no fuel. ”

"The good news is that we're in level flight, and as the speed drops, we lower the altitude, and when the altitude is right, we get out in the escape pod," he said. ”

It is not only the ramjet engine where the shuttle absorbs aviation technology, but also the safety facilities. According to the standards for the construction of shuttles enforced by the Republic, when the shuttle engine stops working or the shuttle loses control, it must be able to disengage using an emergency escape pod.

Of course, for various shuttles with different standards, the means of disengagement of the escape pod are also different. Like the escape cabin of the shuttle that Ding Chen and others are riding now, it is relatively advanced, and it is actually integrated with the crew cabin, which can be directly separated from the body of the shuttle when needed, saving a lot of escape time.

However, because the shuttle has been modified, the escape pod at the front can no longer be used, so in fact, only the six seats in the tail can really be used as an escape pod.

Since there was nothing left to do, everyone had to pack up their things, find a place to sit on their own, and wait for the forced landing to come.

There were now eight people alive on the shuttle, but the bodyguard who had been shot had little hope of rescuing, so Lee Yun-soon decided to give up on him. Also preparing to give up was the agent who had been subdued by Cold Moon.

In Lee Yunshun's view, they have fallen to this point because of these guys, and there is really no need to sacrifice precious resources to take him to a forced landing.

Ding Chen and the three of them had no opinion on this decision, but Ding Chen's sister strongly opposed it, and the reason was of course very simple, that is, they couldn't see death without help.

The shuttle is still flying slowly at an altitude of 10,000 meters. The aerodynamic layout of the shuttle is fairly stable, and although it loses power, it still glides smoothly through the air and drops off slowly, so everyone has plenty of time to rit around the captive.

Ding Chen didn't seem to want to ruin his sister's three views, so he patiently explained to her the importance of life-saving resources. Ding Chen, who had been rummaging for food in the refrigerator, suddenly interjected and said, "I think I can take him with me." ”

"What did you say?" Ding Chen was stunned for a moment and asked, "Why?" ”

"Because only he knows which direction we're flying." Ding Chen said: "Or do any of you know?" ”

Ding Chen glanced at him and was noncommittal. His sister listened to Ding Chen's words, turned her head to look out the window, and suddenly shouted, "I see the ground." ”

Hearing her words, several people turned their heads to look out the window, and sure enough, they found that the shuttle had passed through the clouds, and now they could even see large areas of vegetation on the ground.

"What's that?" Frost's observation was relatively good, and when he saw a fleeting thing flying in the distance, he immediately pointed it out.

Ding Chen was estimating the current altitude, so he reacted a little slower, and turned his head just in time to see the white trail outside the shuttle. He was shocked in his heart and shouted loudly: "That's a missile, sit down, let's make a forced landing." ”
