"Give me the front fingers. Hu Wenhai asked people to pull a telephone line over, and waved his hand to let people dial the phone number that went straight to the front finger.

"General Zhang, what is the situation with Uncle Heng now?" asked Hu Wenhai a little anxiously.

There were still two hours before dawn, and Hu Wenhai didn't point in front, so there was no way to know what trouble Heng Jianyun and they were in. Since someone from above has passed the word, it means that there is a possibility that he may intervene.

The military situation is better than the fire situation, Hu Wenhai has no time to delay, and he comes up to the point.

General Zhang's voice on the phone was still so calm, and he said sincerely: "Their situation is not very good, after the missile hit the bridge, we did not consider that the Annan people would enter the mountains and forests in large numbers in order to avoid follow-up bombing. In order to avoid the crowd entering the mountain, now Heng Jianyun and they have deviated from the planned retreat route. For the sake of concealment, the front finger now does not know where they are. ”

"Comrade Xiaohu, you are the designer of this system, we need your advice now, is there a way to help us contact the Heng Jianyun team?"

Hu Wenhai looked at the results on the Macintosh computer brought back from the United States next to the phone again, nodded vigorously and said: "I have no technical problem here, but there is one thing that needs the consent of the state." ”

"You say. ”

Hu Wenhai paused, and then said firmly: "There may be a flying machine entering the territory of Annam. ”

On the phone, General Zhang fell silent. Hu Wenhai is also aware of the difficulty of this demand; on the one hand, military affairs are a continuation of politics, and no matter how difficult it is in the self-defense counterattack against Annan, we have no air force to cross the line. This was both a reluctance to irritate the Soviets in Cam Ranh Bay. Actually, it's not good. It is also the strength of the Chinese Air Force that is too weak.

Now the Chinese Air Force can only get its hands on the J-7 and J-8. But the Vietnamese have MiG-23 and Su-22 in their hands. Although I don't want to admit it, the Chinese Air Force really doesn't have the cards to play now.

But of course, when the F-14 enters China next year, we don't have to be afraid of the MiG-23 anymore, and we even have to take a bad breath in turn.

But at this point in time, whether or not we can use air power to expand the conflict is a matter of determination.

Hu Wenhai hurriedly added: "I know that the war between China and Angola did not start an air war, but my aircraft is not a manned aircraft. It's drones. We entered at a low altitude, the radar echo was small and hidden in the ground echo, and under the cover of night, my plane could at least hold out until dawn. During this time, we can get Uncle Heng's location at any time, and we can even give them some information support!"

"Two hours!" General Zhang was not a hesitant master, and immediately made up his mind: "You must leave the airspace of Annam before dawn!"

"Yes, General Zhang, please rest assured!" Hu Wenhai even cheered in a low voice, quickly hung up the phone, and nodded to Bai Shi, who was already ready next to him.

"Do the last self-test and take off as fast as possible!" Hu Wenhai ordered loudly.

A few technicians who had arrived from ST quickly got busy. This nearly five-meter UAV has completely lost the appearance of a simulated machine, and completely adopts the mature static and stable fuselage design of later UAVs. The large aspect ratio of nearly 12 gives it the advantage of being able to take off at short distances in the field.

The final self-inspection was quickly completed, and with Hu Wenhai's order, the drone quickly slid a short distance on the battlefield runway and easily jumped into the sky.

The sky was dark at night, and the drone was using a knapsack engine, so that the tail flame could not be seen. The only thing that can be relied on for all operations is the instrument.

The truck next to the runway was loaded with the control console of the drone, and Hu Wenhai neatly climbed onto the body of the liberation truck and nodded slightly.

The drone is operated by the most experienced instructor of Xiucheng Aviation School who flies the simulated aircraft, and this kind of operation experience that will go far beyond the visual distance is also a challenge for him.

Even if radio waves can be transmitted at the speed of light, it is still a somewhat "long" process to be transmitted from the drone to the console, and then from the console to the drone.

Operate the drone needs to be well advanced, any action must be executed two seconds in advance, and any action needs to be completed two seconds in advance.

This is already an operational requirement that cannot be done for Hu Wenhai now.

"Turn on the infrared headlights, let's enter at a low altitude, pay attention to the signal strength!"

"Understood!"

Speaking of which, the people who are more familiar with this system are not Hu Wenhai, but the instructor sitting on the operating platform and Bai Shi, who is climbing into the car body.

Hu Wenhai only proposed design drawings and some technical difficulties, and it was Baishi and his optoelectronic laboratory, as well as Hu Wenhai's grandfather, Hu Shiwu, who turned these drawings and technologies into real objects.

Yes, the old man has not been idle in Xiucheng during this time. After the 606 Institute studied the small turbojet of the simulated machine, Hu Wenhai came up with a set of TRI60 design drawings of the French micro turbine company, and finally designed a modified turbojet suitable for UAVs.

This turbojet has completely lost the shadow of the original toy turbojet, but a truly qualified small turbojet engine. By increasing the number of rotors, stator stages and turbines, the fuel consumption and performance of this turbojet engine have been greatly optimized. Although its thrust-to-weight ratio has decreased, its thrust has increased dramatically, and its safety is not the same.

The structure of TRI60 is more complicated, and Hu Wenhai cannot remember it all clearly. But fortunately, isn't there a co-spy Grumman, swearing by the magic of the little blue pill, Hu Wenhai just mentioned it casually, and he didn't even come out with cash.

This small turbojet engine was later developed and was originally widely used in various UAV power, and of course it was quite reliable in terms of performance. For the time being, there is no imitation of it in China, but it is no problem to adapt measures to local conditions.

The final design result was the old man Hu Shiwu himself, which led to the manufacture of this small turbojet.

In addition, this drone also made Hu Wenhai bloody. Not to mention anything else, just the autopilot, mechanical gyroscope, and radio altimetry installed on the plane are specially prepared for large missiles.

These pieces of equipment alone cost more than 100,000 yuan, which is enough to pay half a month's salary to the workers of Xinke Company.

This drone is complete, and it is conservatively estimated that the cost will be about one million yuan. A group of engineers and scientists from the optoelectronic institute responsible for the specific development and assembly have also seen loser children, but it is the first time they have seen such a loser.

An entire set of U.S. industrial products may be bought back for just one component or a subsystem. But you get what you pay for, and this drone is already the most black technology that Hu Wenhai can assemble at present. If you talk about functionality alone, it is no less advanced than many drones in service in the US military.

As the drone moved deeper into the southern border of Annam, the logo of an aircraft has appeared on the digital map of the previous point. This sudden appearance of the logo quickly attracted the attention of everyone in the command room.

Ten minutes after the plane flew, suddenly, a light infantry logo also appeared on the digital map. Everyone knows that at this time, the troops of our army that appeared in the south of the Laoshan front line will not be anyone else, it can only be Heng Jianyun's team.

The appearance of this logo indicates that they have not been eliminated.

In the command room, a burst of exhalation suddenly sounded.

"Quick, contact Heng Jianyun's team!"

……

"Company commander, company commander!" The correspondent Xiao Cheng crept to Heng Jianyun's side, stuffed the microphone in his hand to him, and said a little incredulously: "The front finger has contacted us, and the chief wants to talk to you!"

"Why, isn't there no signal here?" Heng Jianyun took the phone suspiciously and asked strangely.

"Heng Jianyun?"

The voice from the microphone made Heng Jianyun pause subconsciously, and hurriedly replied in a low voice: "Chief, I'm Heng Jianyun!"

"How are you doing now?"

"Report chief, not very good. We don't dare to act rashly, because we don't know where there is a stronghold of the Annamite in the forest!"

"Your current position, you have deviated from the intended retreat route, if you ...... before sunrise"

General Zhang and Heng Jianyun were talking, but a cold voice interjected: "I'm sorry, please allow me to interrupt, we don't have much time!"

"Comrade Xiaohu?"

"Wenhai, why are you here? This is the military line!"

"It's me. Hu Wenhai hurriedly said: "Your call is now transferred through my drone, so I can cut into the line! Please don't discuss the technical details! We don't have much time!"

"Uncle Heng, there is a group of Annam people in the northwest of your team marching along the foot of the mountain, you must change your route as soon as possible. Walk from the mountainside, 2 kilometers to the northeast, where you will cross a river and climb the northern mountains, I can guide you in the sky to avoid the enemy on this road, but there are only two hours, and the drones will retreat before dawn!"

Heng Jianyun didn't think much about why Hu Wenhai was so clear about the people on the road, but intuitively believed his words.

He waved his hand, gathered the whole platoon together, repeated what Hu Wenhai had just said, and then took the lead and climbed up the mountainside without saying a word!

Hu Wenhai sat next to the drone flight console, and in front of him was a 16-inch color TV. A thermal image of a forest area is being displayed on it. Although it is not particularly clear, the heat emitted by human activity is quite noticeable in the frame.

Hu Wenhai clenched his fists tightly, secretly praying that Heng Jianyun would be able to return to Chinese soil safe and sound. (To be continued......)
