I became a witch, but I started the industrial revolution

With the advancement of electrification, the alliance has gradually begun to try to apply various forces, and magnetic force accounts for the largest proportion of research in the detailed classification.

However, the maglev train is still too advanced for the alliance, and the progress before this was very mediocre.

It was not until the magic research field began to catch up with the progress that the maglev project team made a 180-degree turn and quickly completed the theoretical breakthroughs and actual on-site operation experiments.

The problems encountered by maglev trains before can be classified into three categories: the testing and use of magnetic fields, the absolute temperature control of low-temperature superconductors, and the power supply inside the train.

These three problems are interrelated. For example, in the testing of magnetic field, the manufacturing cost of ordinary electromagnets is very low, but they encounter great obstacles when applied to the train field.

It is well known that the stronger the magnetic force of a magnet, the greater the lift and propulsion, thus achieving a higher speed and levitation.

However, ordinary electromagnets cannot increase the current value to the limit. Due to the thermal eddy current effect, the greater the current value, the higher the temperature of the electromagnet will be, and the magnetic force will quickly decay and weaken. In order to maintain its magnetic strength and magnetic force, it is necessary to increase the energy supply while cooling it down.

To do this, we have to replace it with another type of superconducting magnet. Superconducting magnets are divided into high-temperature superconducting and low-temperature superconducting. This train uses low-temperature superconductors.

When the conductor material reaches below the critical low temperature, it suddenly produces a huge current with zero resistance. That is to say, as long as you pass current through it once, the superconducting coil under zero resistance will circulate this current forever without any energy loss, and the current flowing inside the superconducting coil is far greater than that of ordinary permanent magnets.

In Medea's previous life, in order to keep the superconducting coils under the maglev train in a zero-resistance ultra-low temperature state, a cooling system must be provided, such as a liquid helium refrigeration system.

Liquid oxygen takes away the temperature of the superconductor as it passes through the outer shell of the superconductor. In fact, the superconductor itself no longer needs energy replenishment after the current is injected, but the cooling device used to maintain its ultra-low temperature wastes a lot of electricity.

In addition, a group of superconducting coils must be installed at each side, and the increased weight due to the multiple layers requires a stronger magnetic force to balance, which turns into a difficult problem of adding noodles when there is too much water and adding water when there is too much noodles, making it almost uneconomical.

At the same time, in order to provide magnetic levitation force, inverted figure-8 coils must be densely installed on the track to provide levitation magnetic force for the train. This is another electricity-eating monster.

But these problems do not exist in the magic world. The low temperature required for the low-temperature superconducting state can be maintained normally through magic inscriptions. At the same time, the matrix energy crystal's small size, high energy density, and easy replacement also beat the liquid helium refrigeration system.

The space left after canceling the liquid helium refrigeration is used to install a composite anti-gravity device. The energy supply group is uniformly provided by energy crystals. Combined with the propulsion system composed of ordinary magnets in the track and the anti-gravity inscription array, the anti-gravity train has gone from a drawing to reality.

In experimental tests, the anti-gravity train ran at a maximum speed of 798 kilometers per hour at maximum power, which is truly a close-to-the-ground flight.

However, this speed does not have much practical significance. After it is officially put into operation, the speed will be maintained at around 500 kilometers per hour, and it must be a superconducting dedicated lane.

After all, the manual dispatching center is basically useless at speeds above 500 kilometers per hour. The time from feedback to the train driver receiving the message is enough for the train to crash three or four times. It will be possible to open up operating speeds above 500 kilometers per hour only after subsequent computer systems are reformed on a large scale.

But 500 kilometers is also a disruptive speed. The maximum speed of existing alliance trains is still around 250 kilometers, and the technological gap between laboratory products and products in use is at least three generations.

At present, several special economic zones within the alliance have the need to build anti-gravity superconducting trains. The speed of 500 kilometers per hour can allow each special economic zone to form a three-hour or even one-hour circular economic radiation circle.

In the future, intercontinental routes will be built by constructing vacuum tracks with elevated columns. It is not impossible for anti-gravity superconducting trains to run at subsonic or even supersonic speeds by eliminating air resistance.

However, although this thing looks awesome, it is actually just for foreigners to see. Technology export is impossible. The Central Train Factory of the Union flexed its muscles, and its main export product was another intercontinental wide-gauge double-decker heavy-duty train.

Some officials within the alliance proposed a plan to build at least 3-5 ultra-long-distance train trunk lines with a total length of kilometers on the main continent in the future to directly connect the allied countries on the main continent.

Their idea was that airships were too slow, their large size in the air affected their safety, airplanes had limited range and carrying capacity, and sea transportation could not penetrate deep into the interior of the continent. After all the calculations, trains were the most cost-effective, so they came up with this century-long plan.

With a 2200mm wheelbase and wide-body tracks, the train can be very large. The train height will be around seven meters, the length of the passenger double-decker carriage will be about 420m, and the freight carriage will be extended to about one kilometer, with a maximum speed of over 200 kilometers per hour.

However, this technology is somewhat far-fetched and was refuted by technical experts at the meeting.

This plan is basically impossible. Not only is there the issue of whether or not all countries agree, but even if everyone agrees, building such a long span on the main continent is a big problem in itself.

How to construct? Where do the materials come from? Where does the labor come from? Moreover, the track that can bear the weight of a seven-meter-high double-decker carriage has very strict requirements on steel.

Even if it is really repaired, who will do the daily maintenance and patrol? If someone steals a section of the long railway line, it will be fun to watch. There must be thousands of passengers in the carriages of more than 400 meters. As long as a major accident occurs and causes panic among the people, the entire track operation will be in trouble.

The total investment in this plan is an astronomical figure. If the money cannot be recovered, the loss will be enough to cause several countries to collapse instantly, and the alliance itself may not be able to bear it.

But now that the entire continent is in ruins, it seems that this plan can actually be implemented with some outrageous modifications.

First of all, as various construction plans are subcontracted out, a large number of infrastructure personnel and companies will be spread across most of the continent, and the materials needed for infrastructure also meet the requirements of railway construction. It is theoretically feasible for each region to undertake a part of the construction with them as chain nodes.

However, a super railway network of 10,000 kilometers is still unrealistic, but it is indeed possible to build a zigzag, fragmented construction with each city as a station and connect it into a railway network as a whole.

Similar to an intercontinental logistics train, its 2200mm track gauge allows it to easily carry more resources. It can also be directly called up and used in wartime to provide strong support for the rapid deployment of the alliance's mobile forces.

Coupled with the supporting intercontinental unlimited speed highways, I can't say the whole continent, but the countries within the Seven Alliance are indeed connected to a certain extent on land by rail and road, further reducing the time loss in the transportation of materials.

However, apart from this, the standard track gauge in mainland China will still adopt the standard of 1435 mm. 1435 is sufficient to meet the needs in most cases, and it also significantly reduces the engineering difficulty of cutting mountains, drilling tunnels and building bridges in complex terrain.

The transportation expo in the state of Sivia was just a small episode. In order to minimize the dissatisfaction among representatives of various ethnic groups regarding the alliance's intervention in distribution, the military also held a military exhibition.

At the exhibition, Holy Dragon-class multiple rocket launchers, various heavy armors, tanks and fighter planes were all pulled out for everyone to see and calm down. In addition to these old friends that everyone has seen once or twice, jet fighters that have never been officially equipped in the army also made their debut at the exhibition, and a small test flight show was also held at the base.

As soon as everyone arrived at the airport runway, they were amazed and looked at the fighter jets on display. The design was completely different from that of existing fighter jets, and its minimalist appearance even made everyone who saw it doubt how it could fly.

The crowd and the representatives had the same reason to be amazed. Even they were seeing this thing for the first time, although it had been about ten years since the first generation of jet fighters were manufactured.

The black-skinned girl Aisha, in girl form, walked slowly into the runway amid the astonished gazes of the crowd, completely ignoring the piercing eyes of the crowd outside. It was also the first time that the representatives of various races deeply experienced the boldness and openness within the alliance.

The most advanced technology and a foreign woman appear in the same picture. This scene is really a challenge to the hearts of the old-fashioned people.

But within the alliance, Elsa is the best at flying.

There's no way. Not everyone in this high-risk job like a test pilot can crash a plane dozens of times without getting hurt.

Most of the valuable data in the Alliance aircraft is operated by Elsa. Her demigod body can withstand all kinds of suicidal activities and fly beyond the maximum limit that the machine can withstand.

These data will be fed back to the flight school, and every pilot who graduates will know the maximum carrying capacity of his or her vehicle in reality, apart from the theoretical data, and at what value it will disintegrate and collapse. All these data were obtained from Elsa's fall.

Chapter 347 Technical Bottom Picking

Aisha ignored the gazes of the people outside the field, high-fived the two ground crew members standing under the nose of the plane guarding the boarding stairs, and then began to walk around the plane for self-inspection.

The bright gray delta-wing fuselage has semicircular double air inlets located at the wing connection. The fuselage is an all-metal semi-monocoque structure. The main frame is milled and processed, the secondary spars and airtight partitions are spot welded, and the rest are connected with titanium alloy countersunk rivets or bolts and sealed.

The landing gear main journal, engine fireproof wall plate and some important components are made of titanium alloy. Except for the necessary components, lightweight alloy components are used as much as possible.

F1 fighter (trial production model)

Length/Height/Wingspan: 16.2m/8.6m/4.5m.

Power system: LM-50 afterburning turbojet engine, maximum thrust 50 kN, afterburner thrust 95 kN.

Empty weight is 5400 kg, maximum take-off weight is 16200 kg, maximum flight speed is 2.4 Mach, and range is 4400 km.

Weapon configuration: None.

Several mechanics were chatting not far away, watching Elsa inspect the machine by herself.

They had already adjusted the fighter plane to its optimal state long before Elsa came. As the pilot of the plane, Elsa repeated the check herself both as a procedure and to be responsible for herself.

After completing the inspection, Elsa quickly walked to the nose of the plane, took down the anti-gravity flight suit hanging under the nose and put it on.

This flight suit is not only fireproof and waterproof, but also lined with rubber airbags in the abdomen, legs and buttocks. When the pilot performs maneuvers at high altitudes, the airbags will automatically pressurize and tighten to ensure that the pilot's brain has adequate blood supply.

At the same time, it also serves to fix the internal organs so that they will not be displaced and cause discomfort due to high-overload maneuvers, and effectively alleviate the gray vision and black vision conditions caused by overload maneuvers, allowing pilots to stay awake at all times.

Theoretically, this anti-gravity suit can allow the pilot to withstand an additional 10G of overload based on his physical fitness.

After completing her personal preparations, Elsa strode forward to board the plane, saluted and high-fived the staff guarding the boarding gate, and climbed up the stairs into the aircraft cabin.

After sitting in the cockpit, Elsa put on the communication earphones, stretched out her right hand and hooked the orange button on the screen in front of her right leg to start the main power supply, and the surrounding instrument lights lit up red in turn for detection.

Pull the handbrake, open the fuel valve, left and right fuel boost pumps, start the oil pump, and the inscription energy supply device in turn, then open the switch cover hidden by the thin sheet and press the button. After 2 seconds, the fuselage shakes and the engine starts, and the aircraft engine begins to make a buzzing sound.

After waiting for the engine speed to reach 11%, Aisha pushed the accelerator on the left leg side to the idle position, quickly turned the buttons on the left side in sequence, started the inertial navigation system, turned on the pitot tube heating and emergency hydraulic pump, and turned on the radar to standby.

Finally, turn on the anti-collision lights, navigation lights and formation lights in turn, adjust the radio to the tower receiving channel, turn on the head-up display in front, turn on the radar altimeter below the display, and unlock the attitude display.

Elsa, who was chewing gum, breathed a sigh of relief. She thought about how overwhelmed she was when she first saw those densely packed buttons in front of her. Not only did she have to remember the positions and nouns, she also had to be familiar with the meaning behind each button.

She swore that all the books she had read in her life were not as thick as that pilot's manual...

However...when she knew everything by heart, she could complete all the preparations calmly and smoothly every time, and then a sense of pleasure would slowly surge from the bottom of her heart.

After pressing the last button, the canopy slowly dropped and closed, automatically sealing and pressurizing. Elsa began to wear a pilot helmet. The engine's power output continued to increase in automatic warm-up mode, and the engine speed increased.

The previous buzzing sound continued to expand and gradually turned into a howl. The harsh sound made the crowd watching the scene feel a little uncomfortable, but they were reluctant to take a step back.

After all, this is a rare opportunity to observe the Alliance's new equipment up close, so it would be helpful to take a closer look and then go back and ask my craftsmen to try to make one.

After putting on the helmet and checking that the oxygen supply was normal, Elsa called the ground crew guarding the surrounding to remove the wheel chocks and turn on the front wheel steering paddles. After the ground crew took the wheel chocks and walked sideways to give her a prompt, she released the brake and pushed the accelerator.

The entire fighter plane shook slightly and began to move slowly towards the runway.

As Elsa pushed the throttle to the bottom, a dazzling red light suddenly burst out from the tail nozzle of the fighter jet, and the entire fighter jet slid at full speed. Less than 300 meters away, the aircraft lifted its head and left the ground, and then Elsa retracted the landing gear.

As Elsa pressed the afterburner button, the inscription array near the air intake was activated, and the magic elements floating around were immediately transformed into high-speed gas and sprayed into the air duct. The air duct nozzle at the tail end of the air intake duct sprayed fuel to cause secondary combustion of the high-temperature air.

With the afterburner turned on, the power source once again burst out with nearly twice the kinetic energy of the engine itself under the combined work of magic and afterburner, allowing the fighter to fly 10 meters close to the ground less than 100 meters above the ground, then raise its head in the air, sprinting straight into the air at 90 degrees.

A standard and demanding 90-degree dry onion pulling made the audience exclaim in surprise. Then, after climbing to the highest point, Elsa controlled the fighter plane to do a backflip, turned around and sprinted downwards.

After just these three actions, several Alliance pilots who were watching the fun were moved to tears. The three mechanics who were chatting before also felt their legs go weak, and the chat was completely gone.

Elsa treated the plane like a bomb and was extremely rude.

Afterburner for takeoff, pulling up onions on dry land, and accelerating sprint with a backflip in the air after a rapid climb all put forward stringent requirements on the aircraft's overload resistance, the aircraft's fuselage structure, the engine's power, and the stability of power output.

Just the first round of the silky little combo of afterburner flying, backflip and sprint in the air, if the fighter plane itself is not strong enough or not properly maintained, even if the most drastic structural cracking of the fuselage does not occur, there is a probability that the engine will fail and stop in the air or even stall directly.

Which mechanic wouldn't be scared and have some psychological problems when seeing this? No matter how confident you are in your skills and concentration, you have to constantly review your own maintenance process in your mind when you see the driver going through such troubles, and think about whether you have made any mistakes.

...

After a brief warm-up, Elsa used the potential energy of the dive to turn into level flight and performed a transition maneuver, allowing the audience watching the performance below to clearly see the belly of the fighter plane.

As the first cutscene was completed, Elsa turned around again and stepped on the accelerator to speed up, doing a forward 360-degree spin, then a reverse 360-degree spin and then a forward 360-degree spin, completing the death roll maneuver.

Then it turned on the engine afterburner and quickly passed through the venue, rolled 360 degrees at the end of the audience seats, and then turned at a large angle to face the venue. It once again turned on the engine in the air, and a red light burst out from the tail nozzle of the engine as it passed through the venue at a high speed, followed by a small radius turn.

These actions may seem simple, but they place extremely high demands on the fuselage structure of the fighter when flying at high speed in the air, and Elsa has to bear a load of about 8-10G all the time during the process of such turning maneuvers.

After turning the corner, a high-angle vertical climb and a backflip maneuver were completed smoothly, followed by the final slow approach in the air.

The fuselage of the fighter plane was tilted upwards by 30 degrees, and the engine output thrust at a 30-degree angle, allowing the fuselage to move horizontally and slowly fly over the crowd. From the front of the nose, it looked like a cobra raising its head in an attacking posture.

This maneuver not only tests the pilot, but is also an extremely severe test for the engine, requiring it to provide strong power support while maintaining stable output power.

After about thirty minutes of aerial performance, Elsa slowly landed the fighter jet on the airport runway. As Elsa, wearing a pilot's helmet, climbed down the plane along the ladder, the surroundings once again burst into loud applause and cheers.

However, the expressions of the representatives of various countries were not very good. This kind of aircraft was really a bit incomprehensible. They didn't know whether a similar effect could be achieved through magic.

Engine: "This is fucking bloody!"

The new jet fighters are basically useless in actual combat. Up to now, the Alliance is still invincible in the air battlefield, and it is not even a turn for jet fighters to take action.

Jet fighters are faster and more powerful, but the Alliance’s missile technology has not kept up with development and has yet to demonstrate much actual combat effectiveness.

The embarrassing thing is that it has no corresponding opponent of the same level. Using jet fighters to attack ordinary propeller planes is like using an anti-aircraft gun to kill a mosquito. It is both costly and inefficient.

To put it bluntly, the first-generation air-to-air missile fired in the exercise alone is enough to buy three of the alliance's active fighter jets. If it relies solely on machine gun output, it would be better to build a few more propeller fighters.

According to the alliance's prediction, the application of propeller fighter technology is expected to remain in the leading position in the next 20 years. The development of jet fighters has been maintained, which is more for the exploration of cutting-edge technology and technological reserves.
