The mysterious g-29n, who is still in the project verification machine stage, still aroused great interest from Long Yun after the report was disclosed.

After all, it is no secret of the RCS value of Mi G-29 fighter in the real world. Depending on the band of the irradiated signal, the typical x-band equivalent radar scattering area is about three square meters.

As a comparison, the n019 radar on the MiG-29 fighter jet has a head-on target detection distance of about 80 kilometers for the three square meters of RCS; and if the data in the project report is true, the rCS of MiG-29n is suppressed to about one square meter at zero point. According to the principle of "the radar detection distance is proportional to the fourth power root of the target RCS", the theoretical detection distance of the n019 radar for MiG-29n will be reduced to about 35 kilometers.

From 80 kilometers to 35 kilometers, at first glance, this invisibility ability seems to be a waste of money.

If it is converted according to this ratio, based on the air condition detection capability of the an/apy-1 radar on the US military's e-3a early warning aircraft, if Mig-29n really realizes RCS of zero point one square meter (although Long Yun is not sure how this is achieved), the detection distance in the S-band will only be reduced from 40 kilometers to about 180 kilometers.

The detection distance of more than 200 kilometers at once seemed very powerful, but the MiG-29 who launched an attack at this distance had to further accelerate the penetration until it was within 50 kilometers of the distance e-3a. During this period, NATO's battlefield command system had full time to react. It mobilized the escort fighter jets near the "Wanglou" to conduct interception. The early warning aircraft itself will also change its position depending on the situation. When the threat increases, it will simply turn around and break away from contact.

So from a theoretical analysis, it seems that the G-29n's radar stealth ability is better than nothing and cannot be used to carry out the arduous task of hunting "Wanglou".

However, for Long Yun now, because he has some research on many problems in radar detection, he is very clear that the so-called "fourth power root" law is just a theory, and the actual situation is much more complicated than the formula. If, just if, the RCS of the low detectability verification machine has reached the level of zero point one square meter as the Design Bureau said, then he can be quite confident that the detection distance of the e-3a "Wanglou" early warning machine for the plug-in g-29n fighter will shrink to about one hundred kilometers, or even lower.

As an improved model based on the current MiG-29 fighter, although I have never seen the real thing, Long Yun thought about it and knew that MiG-29n's radar stealth ability is limited and it is far from being called a true stealth fighter.

But even so, what does it matter?

The detection distance of the early warning aircraft is compressed to 100 kilometers, which is enough for the "hunting" operation.

...

During the journey, he thought about some stealth fighter situations, and bursts of fatigue came, and Long Yun quickly fell asleep.

A little dozing on the Mi-28n helicopter flying at an ultra-low altitude. When he was sleeping, he opened his eyes again. The dim dash panel and straight-lined cockpit partitions in front of him had disappeared. In his hazy sight, he could only see beige seat backs under the dim lights of the cabin.

Oh... this should be on the flight. That is, it's time to end the journey and return to the real world.

Before he knew it, after experiencing another time travel on flight tg615, Long Yun thought of the time when he ended his time travel in a parallel world, he was also on a flying helicopter. He took a few deep breaths in his seat to restore consciousness to his consciousness. On the other hand, he also felt that his recent time travel was becoming more and more casual, or it became easier and easier.

Having said that, where are the flights now?

As he thought, he looked beside him. There was still a dark night sky outside the porthole. He couldn't see the starry sky clearly under the diffuse of light in the cabin. Long Yun raised his hand and yawned. He took out his mobile phone to proofread the time zone, and then confirmed that it was around 2 a.m. Beijing time. According to the display on his mobile phone, Flight tg615 should have approached the India-Pakistan border and will soon land in Karachi. Thinking of the plane taking off from Bangkok when he fell asleep before, Long Yun is not sure when he had traveled through time and when he returned.

Well... Long Yun thought to himself that it would be better if this is the case now.

After all, in that parallel world, the Red Empire's strategic counterattack in the Caucasus had already begun, and it made great progress expected on the first day of "anti-radiation combat". With the situation on the day of the decisive battle as a prelude, he can now temporarily rest assured and continue to move forward on the trajectory of his life in the real world.

Although what awaits him on this trajectory is also the battle in the sky.

Less than half an hour after waking up, the TG615 aircraft wheel drew a burst of blue smoke on the runway and successfully landed in Karachi, Pakistan's largest city.

After the flight stopped, following the guidance of the flight attendant on the plane, Long Yun packed his carry-on luggage and walked across the boarding bridge among the passengers shoulder to shoulder. For the first time, he came to Karachi International Airport, walking quickly in the airport lobby, while looking at the bustling concave eye sockets around him with curiosity. As a passerby who had been temporarily staying on the journey, he had no intention of stopping to enjoy the hazy night view near Karachi Airport. Long Yun walked out of the gate with his travel bag and called a taxi with a black background to go straight to the contact address. When he got off the bus, he gave the driver 20 yuan.

The operating rules of taxis in Karachi are also interesting. The price is uniformly 10 yuan, and only long distances such as airports require extra money.

Although it was still midnight local time, some hotels and restaurants in Karachi City were open 24 hours a day, including the Fasimama Hotel, which Long Yun settled and joined in this time. He registered his identity information in the hotel lobby under the name of personal travel. Long Yun found that the "organization" had booked a room for him. He took the door card and went to the room to wash up briefly, and then forced himself to relax, no matter how he went to sleep.

From Beijing to Baghdad, the total number of hours of time difference cannot be completely ignored. Since the mission is about to be performed immediately after arriving at the destination, Long Yun thinks it is better to solve the time difference problem first.

I turned off the lights and rested in a daze, and I don’t know if I really fell asleep this time.
