At an altitude of 10,000 meters, in fact, the problem is not too big for turbojet engines. It's just that for the simulation machine, some improvements must be made in two aspects.

One is the signal problem, the original simulation machine's range of activity is about 1,000 to 3,000 meters high, and the transmission distance is also based on this, and the transmission power of the video and control signal must be increased at an altitude of 10,000 meters.

The second is the engine intake efficiency, in order to obtain sufficient air intake, it is necessary to add a two-pole moving vane and a static vane compressor in front of the small turbojet engine, so that the air pressure is increased by one to two times before entering the combustion chamber compared with the original small turbojet engine.

With these two improvements, the original simulation machine can be enlarged in equal proportions, loaded with more fuel and equipped with a small turbojet engine with a larger diameter, and the simulation machine can fly to an altitude of 10,000 meters.

Hu Wenhai first took a turn in front of this somewhat weird simulation machine, and nodded with satisfaction - just kidding, a group of sixth, seventh, and eighth level old workers made a move, will there be a problem with the things made?

The reason why this simulation machine is a little weird is because there is a big gap in the middle of its fuselage, and it seems that it is preparing to lift something.

Coincidentally, next to this immersive machine, there was an obviously half-finished thing.

And from the appearance, if the semi-finished product is completed, it can be clearly put into the gap in the belly of the simulation machine.

This semi-finished product has an olive-shaped shape, and the opening at the top is still empty, as if there is some equipment waiting to be installed.

The middle of the olive has a slitted window, and a pair of triangular gliders are tucked in.

At the tail of the olive, there are four trapezoidal tails.

That's right, as long as a person with a little common sense has an olive-shaped semi-finished product, there will be a "winged bomb" in his head

impressions.

And this bomb, which seems to have wings, has a tail like a baby's umbilical cord, dragging a long wire to connect to the simulation machine next to it.

Oh, actually, it can't be called a simulation machine now.

Because the real simulation aircraft is designed to simulate the real aircraft, but obviously this simulation aircraft does not have the object of simulation, but according to its power system, the aerodynamic shape of the aircraft is redesigned.

It has a wingspan of two to three meters, a rounded and slender fuselage, a double tail and lower ventral fins.

The camera, which was originally placed in the cockpit, has been moved to the top of the head of the aircraft, and it no longer needs to be blocked from half the view.

Twin-engine small jet engine, air intakes are set to the back of the aircraft.

This is due to the fact that the take-off environment of the UAV battlefield is complex, and even sometimes it is necessary to follow the troops, and the air intake on the back of the aircraft can reduce the possibility of taking off and inhaling foreign bodies, and because the UAV basically does not need to do too drastic maneuvers, it will not lead to the occurrence of insufficient air intake in high maneuvering actions.

Yes, after this series of modifications, the so-called immersive machine has long been out of character.

Or it can be said that now Hu Wenhai's model aircraft can finally barely call a drone.

Without mentioning any gossip, after Hu Wenhai made sure that the carrier aircraft completely met his requirements, he beckoned the three people from Baishi over, pointed to the half-finished aircraft bomb and said: "Director Bai, let's load the receiver into this aircraft bomb next, and then conduct ground tests first." ”

"Bombs?"

Baishi has at least a half-finished aerial bomb more than half a meter long, and his face is embarrassed: "Mr. Hu, our receiver is not prepared for bombing, so we are afraid of fixing ......."

"Hehe, you don't have to worry about that. ”

Hu Wenhai didn't care, patted the bullet body, and said with a smile: "This thing is an empty shell, and the space inside is very large." You remember, space optimization and weapon design are not our job, we don't make weapons, you know?"

"Uh, you know......"

Baishi's head was full of mush, and he understood it in his mouth, but he didn't understand what Hu Wenhai meant at all.

You're going to put the laser receiver on the bomb, and you're a liar if you don't produce weapons!

Hu Wenhai himself didn't find his thinking difficult to understand, after all, he didn't want to be China's Lockheed or Northrop.

It is one thing to supply military enterprises, it is another thing to supply the army directly.

You didn't see the future generations of Huawei, you didn't do anything, a Chinese spy's hat was buttoned up, and he was directly swept away by the Americans?

If Comrade Xiaohu still wants to do business all over the world in the future, then it is best to dress himself up as a harmless little white rabbit for human animals.

As for whether the white rabbit eats carrots or meat...... Oh, hehehehehe.

Regardless of whether Bai Shi understands it or not, under Hu Wenhai's command, he also has to do his job well first.

Fortunately, when this aerial bomb was being manufactured, it obviously took into account the need to install a seeker, and intentionally or unintentionally left a lot of convenient and fixed internal interfaces.

Shiraishi took two scientific research dogs with him, and showed the spirit of fooling if he could.

If there is a fixed joint, use it, and if you don't have it, you can even simply glue it.

The CCD protection lens at the front end of the bomb is fixed to the bomb body with glass glue...... In this way, with the spirit of having the conditions to go up and not having the conditions to create the conditions, in the end, they really stuffed a set of laser receivers into this missile body.

The three of Baishi were busy here, and Hu Wenhai was not idle.

He's operating from the studio next to him - yes, this thing is always evolving.

At the beginning, it could only be placed in the 501 factory office conference room, but later after the volume was reduced and the function was improved, it was placed in the open air.

Now, a small cabin has been built next to the runway, which is completely customized for drones, rather than deliberately imitating the real machine.

Hu Wenhai pulled out a wire socket from the operation shed, then held an Apple Macintosh computer, squatted next to the runway and began to tap the keyboard in the cold wind.

The print interface behind this Macintosh computer is connected to a 64-pin PC104 bus.

On the bus slot, a number of belts are connected to an industrial control single-chip microcomputer inside the bomb.

As Hu Wenhai kept tapping the keyboard, the four tails at the tail of the bullet body began to swing constantly.

Needless to say, the laser scattering positioning of the entire laser guide head is done by him, and the natural interface program must also be completed by him.

Now his job is to convert the operand jù fed back by the infrared guidance head into the guidance law of this aerial bomb.

The so-called guidance law means that if I want to shift the angle of my projectile body by 10 degrees to the right, how should I adjust my rudder surface?

How much time to adjust?

Since the aerodynamic conditions of each flying object are different, the guidance laws are not exactly the same.

If you really want to study the problem of this guidance law, it is no problem to brush up a hundred and ten papers on a bomb type or drone model.

Of course, Hu Wenhai did not have the time for the United States to make such specific calculations and tests, but fortunately, the operation of this missile did not depend on its own guidance law.

The purpose of studying the guidance law is to exhaustively study the guidance accuracy of a kind of aerodynamics and face various unexpected situations.

And now he just has to do a test, of course, there are not so many special cases to consider.

So as long as the bomb can be operated according to the ideal number in clear conditions without wind.

As for the operation effect required by the guide head is not achieved, then another operation command is issued.

If the guidance head asks the projectile to be offset by 10 degrees to the right, and the projectile is only offset by 3 degrees to the right, then another command is issued to offset by 7 degrees.

This time it may be offset by 5 degrees again, so then issue another command to offset by 2 degrees.

If the guidance law is insufficient, let's guide the head to make up for it.

Anyway, it's a test bomb, so you don't have to worry too much about these details.

The wind blew like a knife in the winter in the northeast, and Hu Wenhai was stunned to squat next to the runway and watch the Macintosh computer for more than an hour, before connecting the guidance head and the control system of the missile body.

This is not the end, with his order, Shiraishi turned on the power of the laser target designator in his hand, and a 1.06 micron near-infrared short-wave beam pointed at a fence far away at the end of the runway without being visible to the human eye.

Immediately afterwards, I didn't see any movement from Hu Wenhai, and the tail of the bomb, which had already installed the guide head, actually swayed at an angle by itself!

With Hu Wenhai's command, Baishi operated the laser target designator, constantly moving the invisible laser on the wall.

And the body of this aerial bomb is also swinging its tail like a marionette with this laser.

"Oh, good guy, it's really moving!"

Hao Mingshan asked himself if he was not a person who had never seen the world, he had been an old military worker all his life, and he had never seen such a magical technology!

"Is this thing not going to be able to be instructed?

"Hahaha, Bai Quanyi, your old boy also has a time to show timidity? This is called laser guidance, foreign high-tech!"

Hu Shiwu laughed when he heard this, but he seized an opportunity to laugh at his old fellow.

"Qi—"

Bai Quanyi pursed his lips and muttered sourly: "Virtue!"

Hey, Bai Quanyi moved his steps and moved away from Hu Shiwu, not like this old man - isn't there a genius grandson, what's the big deal, I will let my son have another one when I go back!

I heard that there is a real yàn in the army now, and the indicator of a second child is happening...... Hu Shiwu's arrogance did not detract from the nature of this group of old men, they unanimously gathered around Hu Wenhai and the aerial bombs, and they were amazed by the magical scene of Buddhism.

As a group of veteran military workers, they have gradually tasted the unusualness behind this technology.

Think about the year when the US planes dropped bombs on the US planes to resist US aggression and aid Korea, cutting the entire hill down a few meters, but our soldiers could still survive tenaciously and continue to fight.

But if there is such a weapon, and people throw bombs directly into the tunnels of the volunteers, how can this battle be fought.

Hey, wait, it looks like there's an apprentice of the Volunteer Army fighting with us right now.

The thoughts of this group of old people suddenly drifted to the southern Xinjiang of the motherland, where there are a group of Annan tyrants who don't know whether they are alive or dead.
