Beep!
The command center, accompanied by a long blast.
The land-based radars that were originally blind due to the distance were all able to detect the Black Hawk's signal at this moment.
The signal is so clear, it’s like a big black hawk using a Longbo lens and aiming in the direction of the radar!
Apparently, the damage to the engine had destroyed the Black Hawk's stealth design.
At the same time, the side wall of the combustion chamber is penetrated, and the infrared signal released by the high-temperature fire makes the Big Black Eagle a signal torch in the sky.
"This is the Wildlife Protection Center. Call Protection Team 4. What happened?"
The commander in charge looked at the exponentially decreasing speed of the Big Black Hawk, and hurriedly turned on the microphone and asked about the nearest No. 4 protection formation.
"The No. 4 Protection Group received and through optical instruments found that the Black Hawk scramjet engine was damaged, lost thrust and was gliding downwards. We are maintaining electronic suppression to avoid the enemy base from initiating the Black Hawk self-destruct command!"
"Find out the cause of the damage to the Black Hawk and determine the trajectory, height, speed, angle and other parameters of the Black Hawk's gliding descent."
"No. 4 Protection Formation received."
The wait was less than a minute.
A lot of data is passed back.
The command center analyzes these data immediately.
Soon, the falling trajectory of a black hawk appeared on the big screen.
For a hypersonic aircraft like the Black Hawk, the performance of the aerodynamic layout goes without saying.
Even if the engine thrust is lost, it will not crash in a straight line.
Instead, it slid down like a kite in a gliding trajectory.
“Report, based on calculations.
The Black Hawk glided and fell in a parabolic curve, and its final crash point was close to the border waters.
The longitude and latitude are 24 north latitude...118 east longitude...the sea angle is 18.8°, and the speed is 247.7 kilometers per hour.
If the angle is too large and the speed is too high, the fuselage will completely crash if it falls and collides. "
"Report, the No. 4 protection formation discovered a small drone with a wingspan of two meters, flying at supersonic speed around the Black Hawk. It is suspected to be related to the damage to the Black Hawk engine..."
A two-meter small drone?
It can also cruise at supersonic speed...
The person in charge was stunned for a moment, and then remembered the source of the Black Hawk intelligence.
"No. 4, does the tail flame of this drone have a dense number of Mach rings, and does the engine nozzle have a protruding cone?"
"Report, no Mach rings and nozzle cones were observed, and no protruding cones were seen.
The nozzle of the opponent's engine is similar to the engine nozzle of an ordinary combat aircraft, but it emits a blue glow.
Also, except for the engine nozzles.
There are glowing lights under the fuselage, left and right, and even on the back of the fuselage, just like a hedgehog. "
Blue glow?
Like a hedgehog?
What kind of drone is this...
The person in charge thought for a while: "Send a public coded communication, say hello to the other party, and see if we can contact and communicate with the other party."
"Received, sending public coded communication... Damn it, Cao Cao!"
"What's going on on the 4th? Is there anything abnormal?"
Hearing the shocked shouts in the communication, the person in charge hurriedly asked.
"Report, this drone suddenly rushed towards the target and conducted synchronous docking with the target in the air!
After the docking was completed, it touched the target's rudder, turned the target's direction, and at the same time raised the target's nose with the help of the aerodynamic effect generated by the approach! "
"Report, change in Black Hawk's descent attitude.
Recalculating the trajectory, the Black Hawk's fall trajectory changed from a gliding parabola to a smooth descent curve.
The final crash point was deflected 89 kilometers to the west and 36 kilometers to the north, far away from the border and located 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 and the speed is average. With the help of seawater buffering during fall collision, most of the complete fuselage can be preserved..."
"hiss!"
The person in charge took a deep breath and hurriedly ordered: "Contact the nearby navy, seal off the target fall area, and bring back the fallen black eagle as soon as possible."
"yes!"
The entire command center suddenly became busy.
The person in charge also took out a confidential phone number and reported the current situation.
While waiting for the call to be connected, I was filled with shock as I watched the black hawk's falling trajectory suddenly flatten out on the big screen.
What kind of magical figure is behind this drone?
"Done."
Penghai City Seaside Park.
Looking at the Black Hawk's descent trajectory, Chen Yi made some calculations in his mind, with a look of satisfaction in his eyes.
He believes in being a responsible developing country.
If an ordinary citizen like me throws an object from high altitude and destroys the Black Eagle, the country will definitely be responsible for taking care of it.
After salvage, repair and perfect it carefully, study and repair it carefully, and then send it back.
Ensure that the friendly relations between the two countries will not be destroyed because of this trivial matter.
"It's almost time to go back for lunch, and the battery is less than 3%."
"This supersonic speed machine does consume a lot of battery life."
After hovering in the air for a while, Chen Yi checked the remaining battery power, raised the nose of the plane, and aimed in the direction of Penghai City.
Calculating in his mind, the drone began to accelerate.
When accelerating to subsonic speed, Chen Yi turned off the ion thruster and relied on the drone's good aerodynamic layout to glide towards Penghai.
The battery life is insufficient.
If you want to return home, you can only fly by gliding.
More than half an hour later.
The drone intermittently ignited and boosted several times during the process, gliding hundreds of kilometers to the sky above the park.
Chen Yi restarted the ion thruster and successfully landed the drone nearby with the help of the last bit of electrical energy.
He carried the drone, which had almost run out of propellant, threw away most of its battery, and weighed less than 20 kilograms, back to the car.
Chen Yi drove out of the park, planning to go back to eat and get a good night's sleep.
Buzz buzz...
As soon as I left the park, my cell phone rang next to the armrest box.
One shows no number.
A very special phone at first glance.
"Hey, who's there?"
Chen Yi parked the car on the side of the road and answered the phone.
"Xiao Chen, that drone just now belongs to you, right?"
Professor Zhang's voice sounded on the other end of the phone.
Although the words were questions, the tone was full of affirmation.
"Professor, which one are you talking about?"
"Causing damage to the Black Hawk engine, a drone using plasma propulsion."
"Oh, you said this is mine."
Chen Yi answered honestly: "A newly made rechargeable drone.
I just did a test flight to collect data, and part of the battery was drained.
In order to reduce the load, I abandoned the battery at high altitude.
I just didn't expect that the big black hawk turned on the super-fuel stamping mode, which consumed a lot of money. When I was hungry, I sucked it and ate two pieces of the battery near it.
I did this unintentionally and accidentally fed the big black eagle. You shouldn't hold me responsible. "
"..."
On the other side of the phone, Professor Zhang’s face twitched.
Why this tone and description.
So I owe you Bian.
We deliberately ambush, four flight formations.
In the end, I still sighed in hope and watched the opponent fly away.
You "unintentionally" fed it, but you shot it directly into the soul of the big black eagle.
After taking a few deep breaths, Professor Zhang resisted the urge to beat up Chen Yi and affirmed Chen Yi's contribution in a serious tone.
"Don't worry, we won't hold you responsible. You did a good job this time and made a great contribution."
"Oh, that makes me feel relieved."
"This Black Eagle, if you have time, can you come over and study it together?"
"This..." Chen Yi suddenly became interested: "Can I also participate?"
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 studying such drones.
Among other things, some of the Black Hawk's fuselage structure and appearance layout will also be a great inspiration for his future manufacturing and research of large drones.
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 falconer, can't do it, then no one can."
Professor Zhang smiled and turned to ask: "By the way, how did you achieve it, using ion propulsion in the atmosphere?"
“This is simply a question of thinking.
I improved the engine structure, combined the characteristics of the turbofan duct and ram, and then used electric field acceleration instead of combustion boost acceleration.
The fuselage and engine are designed to be lightweight, and the entire body is made of carbon fiber.
Finally, with a battery with higher energy density, the drone can fly.
But I don’t think you can use this solution. "
Chen Yi did not hide anything and expressed his design ideas openly.
Professor Zhang imagined it and agreed with Chen Yi's statement.
They really can't use this plan.
The price/performance ratio is too low.
To simply understand, Chen Yi's plan still uses the duct and stamping propulsion mode.
It's just that ion electric thrusters are used instead of combustion compressed air, and combined with the lightweight design of carbon fiber throughout the fuselage, the thrust-to-weight ratio of the engine is improved.
This kind of solution looks very high-end, very refined, and looks very handsome when used.
But for this high-end sophistication and handsomeness.
But it sacrifices the engine's afterburner burst performance and the high-temperature resistance of modern combat aircraft.
Of course, the most important thing is that it sacrifices endurance and sustained combat capabilities.
Modern combat aircraft for long-lasting air combat.
Aerial tankers can wait aside to cover and refuel at any time.
To perform long-endurance missions, aerial tankers can also replenish fuel in the air in advance, and the endurance can be easily increased to tens of thousands of kilometers.
But what if it were replaced by a rechargeable ion-propulsion drone like Chen Yi.
The air battle was in full swing when a teammate suddenly said something.
Who can open the back of my head, oh no, open the back cover of the fuselage, and change a battery in the air?
Before he was killed by the enemy, he himself collapsed first.
"If we can have a small reactor and add an extended-range power generation system to improve its permanent endurance, this ion-propelled combat aircraft will have great potential.
Relying on the characteristics of ion thrusters.
Whether it is low-altitude, high-altitude, ultra-high-altitude critical space, or space, cross-planetary operations can be adapted to all. "
Professor Zhang thought of another plan, but rejected it the next second.
Putting a reactor into the belly of an aircraft and matching it with a range extension system is unrealistic and too ultra-modern.
