The man couldn't answer, so Qin Shuai stepped forward and pointed his tester at him.

A line of words appeared like instructions.

"Extraterrestrial stuff?"

"Back to sir, I picked it up."

"Didn't everyone call me Deputy Sergeant Major, how did I become a sergeant?"

"Back to the deputy sergeant major, I picked it up."

"Hehe, you really look like an alien, or a robot."

Qin Shuai sensed that something was wrong with his ears, there seemed to be a chip on it, maybe it was controlled by this chip.

He deliberately stepped forward and pretended to sort out his military hat, and then touched his ear, and the chip was in Qin Shuai's hand, and he felt a little dizzy.

Qin Shuai asked him to sit down and rest.

Qin Shuai took this recorder and compared it with the recorder just now, it turned out that the two recorders were slightly different, and the functions inside were also different.

This one's machine seems to be more advanced, because he seems to have been semi-controlled, so he is very flexible to manipulate this machine, and it is well hidden, but Qin Shuai can still feel the existence of this thing, and he is also a little surprised.

He pretended to be angry, so he deliberately broke these two things with his hands, and then found that these things could be restored to their original state, as long as they were pressed together, and then turned into a voice recorder, it seemed that this was a magical material, different from the materials on the earth, if these small machine parts on the earth, it would be impossible to restore them in this way.

Qin Shuai had an idea, broke the two machines again, and then put the second half and the first half together, this thing was originally corresponding, but I didn't expect that when they were put together, there was a magical band, and then it was transmitted to the aliens, through Qin Shuai's test device, the external sound, they only heard the sound of squeaking, and after a while, they heard the sound of explosion, it turned out that they were alien energy repulsion, and there was a very magical band, which blew up their eavesdropping device.

And when their eavesdropping device exploded, several other undercover voice recorders also began to explode on their own. Fortunately, the explosion was not strong, but they were all injured.

Therefore, among these non-commissioned officers, all these undercover agents were discovered. Qin Shuai immediately called them all to his side.

They looked at Qin Shuai tremblingly, they couldn't hide it anymore at this moment, because their identities had been exposed, they immediately went to get the equipment on their waists and their pistols, but Qin Shuai suddenly stretched out his legs and feet, and quickly knocked them down one by one.

The non-commissioned officers rushed up, arrested them one after another, tied them up, and sent them to the interrogation room.

At the headquarters of the Union Army, there was an interrogation room, which was dedicated to some undercover agents and prisoners. Qin Shuai didn't let them interrogate these people in a hurry, but temporarily put them under house arrest, in fact, they were quite pitiful, because they were all controlled by chips.

After Qin Shuai took off these chips, they all felt dizzy, so Qin Shuai ordered the kitchen to make them some delicious food, and the non-commissioned officers were very surprised, why Qin Shuai didn't punish them.

But Qin Shuai told them that once they are controlled by the chip, no matter how capable they are, they will probably become like this.

Others said they didn't quite understand, but Qin Chuan knew how terrifying this chip was, and some officers and soldiers in the headquarters of the Federal Army had actually encountered a similar situation, once they were controlled by the chip, they were likely to become alien human robots, looking no different from earthlings, like a non-commissioned officer, but their thinking was all towards aliens.

They looked at the time, at this time they could also give everyone military training, and returned to their conference room, Qin Shuai planned to continue to explain to everyone, some people were hungry and arranged to go to the kitchen to find food, and those who were willing to stay listened to Qin Shuai's new military course.

The military combat aircraft designed by Qin Shuai has many advantages.

As a fighter, the requirements for the flight performance and weapon capabilities of his design will only be higher. Fighters require quite high speed and altitude, which are not available for trainers in general.

Even in order to meet the basic requirements of a medium-performance fighter, the maximum speed needs to be increased to at least about 1.5 times the speed of sound, and the ceiling is correspondingly increased.

To this end, Qin Shuai designed to use the fighter's low-flow ratio afterburner turbofan engine. This also happens to be the engine used by many business aircraft, because of its low fuel consumption and good reliability. Fighter engines pursue ultimate performance, like high-performance sports car engines, and trainer engines pursue reliable and fuel-efficient, like taxi engines. The requirements of the two are different, replacing the former with the latter cannot meet the performance requirements at all, and replacing the latter with the former will lose reliability and fuel consumption.

In his opinion, the economy of the use of fighter engines for training aircraft is another bad news. The maneuverability requirements of the fighter are much higher than those of the trainer, which requires the body to be greatly strengthened, which in turn increases the weight and the resulting economic loss of use.

Qin Chuan was surprised: "...... And that's not even about avionics? ”

Qin Shuai replied: "The trainer does not need too much avionics, as long as it has basic flight instruments and communications. But as a tactical aircraft, a fire control system is necessary and needs to be matched with all the matching weapons. …… Although modern fire control is digital, as long as the hardware is there, the software can be updated at any time, the software has no weight, and the software cost is mainly in development, not in copying. Now that it has been developed, loading or not loading the fire control system has little to no effect on the cost of the software. ”

He also said: "The cost of hardware is related to the output, but also limited, to the cost of research and development and tooling has been negligible, materials, manufacturing and other costs determine the cost of hardware to reduce the space." If the training aircraft is the cost of modern fire control, the cost will definitely not be low......"

Qin Chuan was surprised: "What if you only use simple fire control? ”

Qin Shuai said: "There is only the first on the battlefield, there is no second, and simple fire control is only effective when the enemy is very meaty, but except for countries that simply cannot afford modern fighters, even the training aircraft are responsible for the heavy responsibility, and then the battlefield survivability of the training aircraft is very problematic." But to upgrade the fire control to the point where it can fight a war, the cost has increased significantly...... The high cost of modern fighters is still climbing up little by little under strict cost control. In addition to the fact that everyone is confused, the low cost that the fighter cannot do may not be able to be replaced by a trainer aircraft......"
