This civilization is very strong, but the technology tree is a bit crooked.

Chapter 38 This plan is too modern

beep!

Command center, accompanied by a long beep.

Because of the distance, the ground-based radar, which was blind like a man, has all detected the Black Hawk's signal at this moment.

The clarity of the signal is like a big black eagle driving a Longbo lens and aiming at the direction of the radar!
Obviously, the damage to the engine has undermined the stealth design of the Black Hawk.

At the same time, the side wall of the combustion chamber is pierced, and the infrared signal released by the high-temperature fire makes the big black eagle a signal torch point in the sky.

"This is the Wildlife Conservation Center, call the No. 4 protection formation, what happened?"

The person in charge of the command looked at the exponentially decreasing speed of the big black eagle, and hastily turned on the microphone to ask about the nearest No. 4 protection formation.

"The No. 4 protection formation received, through optical instruments, found that the Black Hawk scramjet engine is damaged, lost thrust and is gliding and descending. We are maintaining electronic suppression to prevent the enemy base from activating the Black Hawk self-destruct command!"

"Find out the cause of the Black Hawk's damage, and determine the trajectory, height, speed, angle and other parameters of the Black Hawk's gliding descent."

"Received by Protection Formation No. 4."

Waited less than 1 minutes.

A lot of data is passed back.

The command center analyzes these data immediately.

Soon, the falling track of a Black Hawk appeared on the big screen.

For a supersonic aircraft like the Black Hawk, the performance of the aerodynamic layout is needless to say.

Even without engine thrust, it's impossible to crash in a straight line.

Instead, it slides down like a kite with a gliding trajectory.

"Report, according to calculations.

The Black Hawk glides and falls in a parabolic curve, and the final landing point is close to the border sea area.

Longitude and latitude 24 north latitude 118 east longitude enters the sea at an angle of 18.8°, and the speed is 247.7 kilometers per hour.

If the angle is too large and the speed is too large, the crash of the fuselage will completely crash. "

"Report, the No. 4 protection formation found a small UAV with a wingspan of two meters, which is orbiting the Black Hawk for supersonic endurance. It is suspected to be related to the damage of the Black Hawk engine"

Two-meter small drone?
It can also cruise at supersonic speeds.
The person in charge froze for a moment, then remembered the source of the Black Hawk intelligence.

"No. 4, the tail flame of this drone, is the number of Mach rings very dense, and the nozzle of the engine has a protruding cone?"

"Report, no Mach rings, no vent cones, no protruding cones were observed.

The nozzles of the opponent's engine were similar in structure to those of ordinary fighter planes, but what they emitted was an azure blue glow.

Also, except for the nozzles of the engine.

Under the fuselage, on the left and right, and even on the back of the fuselage, there are glows spraying, just like a hedgehog. "

blue glow?

Like a hedgehog?
what drone is this
The person in charge thought for a while: "Send a public code communication, say hello to the other party, and see if you can communicate with the other party."

"Got it, I'm sending a public coded communication, fuck Cao Cao!"

"What's the situation on the 4th, is there anything abnormal?"

Hearing the shocked shouts in the communication, the person in charge hurriedly asked.

"Report, this UAV suddenly rushed towards the target, and made an air-synchronous docking with the target!

After the docking was completed, it touched the target's rudder and turned the target's direction. At the same time, it lifted the target's nose with the help of the aerodynamic effect generated by the approach! "

"Report, Blackhawk's descent attitude changed.

After recalculating the trajectory, the falling trajectory of the Black Hawk changed from a gliding parabolic curve to a smooth descending curve.

The final point of impact was deflected 89 kilometers to the west and 36 kilometers to the north, far from the boundary in the inland sea area.

The angle of entry into the sea is 7.3° and the speed is 102 kilometers per hour.

The angle is gentle, the speed is average, and the impact of the fall is buffered by sea water, so most of the complete fuselage can be preserved.”

"hiss!"

The person in charge took a deep breath and hastily ordered: "Contact the nearby navy, seal off the target crash area, and bring back the fallen big black eagle as soon as possible."

"Yes!"

The entire command center suddenly became busy.

The person in charge also took out the confidential phone and reported the current situation.

While waiting for the call to be connected, watching the black eagle's falling trajectory that suddenly became flat on the big screen, my heart was full of shock.

What kind of fairy is behind this drone!
"It's done."

Penghai Seaside Park.

Looking at the descending trajectory of the black eagle, Chen Yi calculated in his heart, with a look of satisfaction in his eyes.

He believes in being a responsible developing country.

The country will definitely be responsible for the black eagle that was smashed by ordinary people throwing objects from high altitude.

It was salvaged and carefully repaired and perfected, carefully studied and repaired, and then sent back.

Make sure that the friendly relationship between the two countries will not be destroyed because of this trivial matter.

"It's almost back to lunch, and the battery is less than 3 percent."

"This ultra-high-sonic speed machine consumes a lot of battery life."

Hovering in the air for a while, Chen Yi checked the remaining power, raised the nose, and aimed in the direction of Penghai City.

Calculating in my mind, the drone began to accelerate.

When accelerating to subsonic speed, Chen Yi turned off the ion thrusters, and relied on the drone's good aerodynamic layout to glide to Penghai.

Battery life is insufficient.

If you want to return home, you can only fly by gliding.

After half an hour.

The UAV intermittently ignited and assisted several times, gliding hundreds of kilometers, and came to the sky above the park.

Chen Yi restarted the ion thruster, and with the last bit of electrical energy, he successfully landed the drone nearby.

Carry the unmanned aerial vehicle, which has almost exhausted its propellant, discarded most of its batteries, and weighs less than 20 kilograms, back to the vehicle.

Chen Yi drove away from the park, ready to go back to eat and catch up on a good night's sleep.

buzzing.
As soon as he left the park, the cell phone next to the armrest box rang.

One doesn't show a number.

A very special phone at first sight.

"Hello, who is it?"

Chen Yi parked the car on the side of the road and connected the phone.

"Xiao Chen, that drone just now belongs to you, right?"

Professor Zhang's voice rang from the other end of the phone.

Although the words were inquiries, the tone was full of affirmation.

"Professor, which plane are you talking about?"

"Causes Black Hawk engine damage, using plasma-propelled drones."

"Oh, you said this, it's mine."

Chen Yi answered honestly: "The newly-made rechargeable drone.

I just took a test flight to collect data, and some of the batteries are exhausted.

In order to reduce the load, I dropped the battery at high altitude.

It's just that I didn't expect that the big black eagle turned on the scram mode, which consumed a lot of energy. When I was hungry, I sucked it and ate two batteries near it.

I also did this unintentionally. I accidentally fed the big black eagle. You should not hold me accountable. "

"."

On the other side of the phone, Professor Zhang's face twitched.

Why this tone and description.

So flat.

We deliberately ambushed, four flight formations.

In the end, he still sighed in hope of winning, and watched the other party rush away.

You "unintentionally" fed it, but you directly fell into the soul of the big black eagle.

Taking a few deep breaths, Professor Zhang resisted the urge to beat Chen Yi up, and affirmed Chen Yi's contribution in a serious tone.

"Don't worry, you will not be held accountable. You have done a good job this time, and you have made great contributions."

"Oh, that puts my mind at ease."

"This Black Eagle, if you have time, come and study together?"

"This..." Chen Yi suddenly became interested: "Can I participate too?"

This is the 18-meter Black Hawk, the famous SR-72, one of the world's top large drones.

As a drone enthusiast, I am naturally interested in researching such drones.

Among other things, some of the Black Hawk's fuselage structure and shape layout are a great inspiration for him to manufacture and research large-scale drones in the future.

The stealth design of the fuselage is even more inspiring for Chen Yi to design the stealth function of his own drone.

"If you, the falcon catcher, can't do it, then nobody can."

Professor Zhang smiled, and asked again: "By the way, how did you realize the use of ion propulsion in the atmosphere?"

"It's simple, it's just a matter of thinking.

I have improved the engine structure, combining the characteristics of turbofan ducting and ram, and then using electric field acceleration instead of combustion boost acceleration.

The fuselage and engine are designed to be lightweight, and the whole body is made of carbon fiber.

Finally, with a battery with higher energy density, the drone can fly.

But this plan, I don't think you can use it. "

Chen Yi didn't hide anything, and expressed his design ideas openly.

Professor Zhang imagined it and admitted what Chen Yi said.

They really can't use this plan.

The price/performance ratio is too low.

Simply understand, Chen Yi's plan is still a propulsion mode of ducting and stamping.

It's just that the combustion compressed air is replaced by ion electric propulsion, and combined with the light and lightweight design of the whole body carbon fiber, the thrust-to-weight ratio of the engine is improved.

Such a solution looks very advanced, very delicate, and very handsome to use.

But for this advanced refinement and handsomeness.

However, the afterburner explosive performance of the engine was sacrificed, and the high temperature resistance performance of modern combat aircraft was sacrificed.

Of course, the most important thing is to sacrifice endurance and continuous combat capability.

Modern combat aircraft, when engaged in protracted air combat.

The aerial refueling plane can wait on the side and cover refueling at any time.

Performing long-endurance missions can also replenish fuel in the air in advance of the air tanker, and the endurance can be easily increased to tens of thousands of kilometers.

But if it is replaced by Chen Yi's rechargeable ion-propelled drone.

The air battle was in full swing, and a teammate suddenly said something.

Who can open the back of my head, oh no, open the back cover of the fuselage, and change the battery for me in the air?
This was not killed by the enemy, and he collapsed first.

"If there is a small reactor, an extended-range power generation system can be added, and the permanent endurance can be improved, this ion-propelled combat aircraft can do a lot.

By virtue of the characteristics of ion thrusters.

Whether it is low-altitude, high-altitude, ultra-high-altitude critical space, or space, cross-planet operations, all can be adapted. "

Professor Zhang thought of another plan, but the next second he denied it.

Stuffing the reactor into the belly of an aircraft and matching it with a range extender system is unrealistic and too modern.
