"Well, it wasn't far away by the time we called, so there we were. Pen Fun Pavilion www.biquge.info"

Lin Mo smiled and nodded, stretched out his hand to scratch Qi Fei's white and tender nose, and he turned his gaze to the wind tunnel pipeline in operation, a beam of pure white smoke was directly following the wind and accurately scaled down the A-10 "Warthog" attack aircraft model.

He didn't expect Qi Fei to choose this aerodynamic shape as a replica attack aircraft.

"See, it's no longer a propeller engine, it's a semi-jet engine!"

Qi Fei pointed to the rear of the main wing of the fuselage, which was being tested by the high-speed air flow in the wind tunnel, next to the two barrel-like objects in front of the tail.

"Jet engines, is there a solution to the fuel source?"

Lin Mo looked at the two semi-jet engines curiously, the jet engine and the propeller engine belong to a completely different power field, even if there are ready-made technical reference materials, but such a large generation span, it is by no means easy.

Although the propeller engine is easy to maintain and reliable, it has congenital technical defects, even if the electric drive technology is used, even if the output power is large, it is difficult to make the speed of the aircraft close to the speed of sound, and even the edge of subsonic speed cannot be touched.

"Jet technology is nothing more than the principle of air thermal expansion to produce thrust, we start directly from the essence, the front half is no different from the jet engine, high-speed turbofan intake, the middle is the air thermal expansion chamber, you can use resistance wire heating and spell array to jointly heat up the air, resulting in expansion and thrust. ”

Qi Fei took out a tablet from his spatial alchemy memory, connected it to the ubiquitous WiFi environment in the Dragoon Magic Industrial Zone, and quickly called up a design analysis drawing.

Lin Mo looked at it and was happy.

What kind of semi-jet engine is this, and it's clearly a large electric hair dryer.

To put it professionally, it is a ducted turbofan engine, which is quite suitable with electric drive, and it is also an electric tiger, with the same output power. If there is no increase in air heating design, I am afraid that the cost-effectiveness ratio will be very worrying, and the performance is still not much better.

When I was on Earth, in the secret booklet passed down by Professor Yan, my teacher in the field of aeronautical design, before his death, this belonged to the evil design that was difficult to get into the hall of elegance, and it was okay to get one or two verification machines as technical reserves, but it was impossible to install them in the active sequence.

Maybe even Qi Fei himself doesn't know, but the most used field of ducted engines is model toys. If a physical prototype is really made to scale, supersonic is not a thought at all, and at best it is a big toy.

Compared to the original A-10 "Warthog", this knock-off can only be called a White Rock old sow, which has nothing to show for itself, but does not really match the performance.

"What are you laughing at? Am I not good at designing?"

Qi Fei saw Lin Mo's strange expression on his face, and immediately became angry, the information for building the aircraft was all provided by him, and he just copied it with a little imagination.

To be wrong. It's also the fault of this dead wood.

"Well, I can only say that I am barely able to do it!

Lin Mo didn't deliberately pat himself on the back, but gave a pertinent evaluation.

The main tactical objective of the attack aircraft is to provide ground support at low altitudes in depth, that is, to attack and jump large. It is also known as a strong attack aircraft, and at the same time has a certain ability to protect itself in air combat, and often becomes the controller of local battles on the battlefield, and a series of unreasonable killing moves are released. Punching the master to death is definitely a fear for everyone, and any enemy who tries to rely on the city wall for defense will reap the consequences.

Despite the use of ducted turbofan engines. For the sake of twin engines, the consumption of magic crystals is definitely more than double that of the "Rising Dragon", and the flight speed may barely be able to compete with the Flying Dragon, but the long hanging with the diameter configuration of the single is the highlight, which can be loaded with enough ammunition to make up for the weakness of the insufficient attack power of the "Rising Dragon" propeller fighter.

If the Tessie light-wing ship is against this attack aircraft, it is obvious that most of the time it will be hit to its knees in minutes, and it will be beaten all over the ground looking for teeth.

"Really?"

Qi Fei wrinkled her nose, with suspicion in her eyes, she was not a three-year-old child, and she was allowed to be played with.

"It's more real than real gold, and it's guaranteed to be 28k. ”

Lin Mo hurriedly nodded vigorously.

"It's nonsense again, the highest gold is only 24k, where does it come from 28k?"

Qi Fei punched the word Wing Chun and punched Lin Mo's chest.

This wood can't even tell a lie, it's really infuriating!

"Really? hahaha!

This hit the muzzle of the gun! Lin Mo touched the back of his head in embarrassment.

The time spent on Earth is too short, the memory fusion is not comprehensive, and most of the time is tinkering with the forward-swept deformer-wing fighter, or fighting and killing, and there is still a lot of lack of common sense in life.

"Where's the stuff, take it out!"

Qi Fei stopped joking with Lin Mo, his face straightened, and he stretched out his hand to the dragon knight.

"What?"

Lin Mo was stunned.

Qi Fei hated the iron and said with hatred: "The new materials you brought back!"

The front foot is still talking, why did the back foot forget?

This is to the girl to death!

"Ugh!~ I almost forgot. ”

Lin Mo hurriedly slipped out of the alchemy storage on his right wrist with two broad-bladed swords and a battle helmet.

Smack!~ Qi Fei snapped his fingers.

"Meridian!"

"In!"

A burly man in armor walked over from the corner of the wind tunnel laboratory, and at the same time slammed his chest hard at Lin Mo respectfully.

"Lord Morin!"

Ziwu, the head of the security group, is a follower of Lin Mo, but he is left behind to lead the security team and protect Qi Fei from Dragoon Magic Industries.

This northern man is a first-order powerhouse, with a thunder light heavy prison axe, his strength should not be underestimated, and he is loyal, and he has always been trusted by Lin Mo and Qi Fei and other sisters.

"Let's go to the shooting range and practice first!"

Qi Fei has always been vigorous and resolute, and he does it when he thinks of it, perhaps it is because of this personal charm that the execution and efficiency of Dragoon Magic Industry are incomparable to any workshop and shop in the outside world.

"Yes!

Ziwu bent down, took two broad-edged thick swords, and shook them slightly.

"Go ahead! Send the technical analysis report to my email before you get off work!"

Zifi gestured to the mages and alchemists who were working in the wind tunnel laboratory.

"Guaranteed to reach your mailbox by 7 p.m.!"

The project leader made an OK gesture, an action that was popular among alchemists.

"Let's go!"

Qi Fei hugged Lin Mo's arm with a smile, half hanging on him like a koala.

The dragon knight had no choice but to let this girl rely on her, and directly dragged her out of the wind tunnel laboratory.

The head of the security regiment, Ziwu, was expressionless, completely ignoring the intimate scene of a man and a woman in front of him.

The Dragoon Magic Industrial Special Weapon Training Ground, a 100-meter-thick, 50-meter-high triple rammed earth wall encloses this sandy land with an area of nearly 10,000 square meters.

Whether it is cold weapons, firearms, or ground assault drills for constructing combat aircraft, they are usually conducted in secret here.

At least three days a week, the walls can be heard with various sounds of banging and banging, as well as rising black or white smoke, and sometimes yellow smoke.

In a way, the significance of this trial ground is not much different from the 51st area of the old beautiful broom, many things are not enough for outsiders, and the rammed earth wall blessed by magic is both protection and isolation.

Click!~

A sword mark as deep as an inch appeared on the dark steel pillar that one person was hugging.

"Good sword!"

It's just that it took fifty percent of his strength, Ziwu glanced at the broad-bladed thick sword in his hand, and couldn't help but give a thumbs up.

The sharpness of the blade was something he hadn't expected, and it was able to leave such deep marks on the surface of the steel.

"Change the helmet and use the long sword to slash first!"

Qi Fei was very satisfied with the results of several cold weapon tests, and she changed to another test subject, the purple battle helmet in Lin Mo's hand.

Don't look at the weight of the first hand, it is not heavy, but the strength of this battle helmet far exceeds Qi Fei and Ziwu's imagination.

Rumble!~

A mushroom cloud of 100 kilograms of standard explosives rises, and the shock wave carries the sand particles as if it were a sandstorm.

"Isn't that bad?"

Qi Fei rushed forward with a breath filter mask, and quickly found the broad-bladed sword and helmet that had been thrown away from the center of the explosion, and the dark steel chains used to bind them had been blown off, and the two things were still intact, and there was not even a single obvious abrasion mark on the surface.

"It's scary!"

The broad-bladed sword and battle helmet that Qi Fei brought back made Ziwu look dumbfounded.

So that it won't be damaged?

He couldn't help but peek at Lin Mo, how did the enemy wearing this invincible armor and holding this divine weapon be killed by Lord Morin?!

"No need to try!" Lin Mo shook his head, and then said: "The full power launch of any caliber of the electromagnetic orbital rifle has not been able to penetrate this armor, and the spell attack is also ineffective, to be precise, it should be both physical and demonic!"

"It's great, and if it can be used to build the outer skin armor of the aircraft, the performance of the aircraft will be taken to the next level. ”

Qi Fei looked at the three trophies brought back by Lin Mo with bright eyes, and began to fantasize that the legendary "flying tank" was about to be born in his own hands, and the fragile nature of the aircraft was reconstructed, which was definitely a great creation that could go down in history.

It is conceivable that if these "flying tanks" cannot defeat their opponents, will they not be able to hit their opponents? Their incomparably hard wings can even slash them to death, and they are simply cold weapons in the age of firearms.
