Without suitable engine support, the institute has opened a big topic for aerial reconnaissance and countermeasures units.
The so-called topic size is re-divided according to the teachings of Teacher Li Xiang and based on the abilities and strengths of the mages.
For example, the weapon series, Python, Cat, Eagle, Caroline rifle, and Heavy Rain cannon are all sub-topics of kinetic weapons, while Styx belongs to the battlefield magic and magic array subject group.
Aerial reconnaissance and countermeasures involve aerodynamics, attitude control, dynamics, etc., and require many teams.
When there are more people, there are more ideas.
Li Xiang has taught a lot of aerodynamics-related courses to the institute, and has even drawn various flying machines based on speed, so that everyone can intuitively understand issues related to air resistance and lift.
Therefore, if you want to build a mechanical flying object, you don’t need to choose a model. Just use a horizontal monoplane. No sweep angle is needed at the beginning. The maximum speed of a straight-shaped wing is slow, and the low-speed lift ratio is large. It will be relatively safer. Once you have a certain Scale pilots then consider increasing speed.
The debate within the research group also started from this point.
"In fact, there is no need to build an airplane. We can directly use magic to take people to the sky, which can also simplify the manufacturing process." A loyal fan of the magic system said this.
The mechanical team also had reasons to retort: "The army is full of Muggles. Even if we use magic to take people to heaven, we still need a magic circuit operating system that can be controlled by Muggles. Is it really that simple?"
Caroline returned to the institute and quickly built a visual system for heavy industry to control machining accuracy. However, that thing could not actually be operated by Muggles in real time. It only showed them the status of the workpiece as a reference for processing.
In order for Muggles to operate magic devices, many problems need to be solved. For example, Muggles may cause magic disorder in the magic circuit at the contact point. This requires a mechanism for transmitting kinetic energy and ensuring that the kinetic energy can output correct operating signals.
Pure machinery will undoubtedly make production difficult, but the threshold for use is low. To swing the wings in a certain direction, you only need a few steel cables to pull the relevant rudder surfaces. The operation relationship of the concentrated parts of the steel cables must be handled well. Single or double lever operation can be achieved.

And it is not truly pure machinery, because the existing engines are not good enough. The radial engine is a new subject that has only been taught in the past few days. It is still far from being realized. It is also unknown whether it can meet the power requirements of flying vehicles. So at this stage It still has to be driven by magic.
Neither group could convince the other, so in the end the dean of the seminary decided that we would work in groups to make prototypes to see the effect, and let the superiors choose, and then we would specialize in one type.
Obviously, the institute's accumulation is far from being able to build a practical aircraft in one step.
The propeller was solved with magic, but other completely unexpected situations occurred.
Mages will instinctively apply enchanting effects such as light feathers, floating, and flying to flying objects. The lighter they are, the easier they will be to fly.
But after making the small model machine, I discovered that it had no lift!
After investigating by blowing smoke, it was found that three spells usually used to assist flight will affect the flow of gas across the surface of the wing.
Flight, for example, causes gases to accelerate across a surface and concentrate in the corresponding direction to provide a thrust to the target.
This thrust is very small. When placed on a human body, it only accounts for about 5% of the human body weight. But when placed on an airplane model, the impact becomes very large because its airflow direction is downward by default!
The team members just learned the magic step by step and didn't even understand which part of the spell was used to control the direction of the air flow, so they had to remove it.
Floating and Qingyu are in a similar situation, each has its own abnormalities, and in the end they can only be removed.
After removing it, the power shaft is required to have greater power, which is another part that it is not good at.
Compared with machinery, magic is not good at producing stable, fixed-point, and directional output shaft power. It's not that it can't, but that it consumes a lot of money.
Take the flying spell as an example. The mage has to pay 0.5 mana hours of mana, which is almost equivalent to the traditional measurement of four minte. It can make a person fly, but it can only fly for a short time. Depending on the individual mana control level, the time ranges from 20 to 20. 100 seconds, but as long as the magic is activated, the cost of maintaining flight will be relatively small. An additional fifteen minutes of flight time will only consume an additional 0.5 mana hours.
In other words, for one spell, the amount of magic close to the lower limit of a fourth-ring mage can keep a person flying for sixteen minutes.
But when placed on a magic device, it is necessary to create a force equivalent to a person's resting weight. Even if it is 600 N, if a person flies, it can be seen as at least 600 N of force against gravity.
To maintain the power of 600 Nm per second, it is 600 watts. According to the magic power, it takes about 50 magic power. This is not the power required for startup but maintenance. That is, the magic power can only be maintained for a little more than one minute per magic hour.
From the perspective of utilization rate, 50 methods driving 600 Nm is actually not bad. The "method" is determined by the minimum Mars energy of the magic circle of the spark trick. It is determined by referring to the force required for a person to scrape a magnesium rod with a knife to generate sparks. Less than 10 Nm, the two systems are completely different, but both are used to do work and the effects can be slightly compared.
What's more serious is that when used in aerodynamics, 600 watts of power cannot make an object weighing a person fly while controlling movement in all directions.
For reference, the Flyer One (made by Lite Brothers in 1903) has a take-off weight of 360 kilograms (empty weight: 274 kilograms), an engine of 12 horsepower (about 8.8 kilowatts), and a flight speed of 3 meters per second.
It can be seen that even in Malaysia (kilowatts are used as a power unit), one horsepower can only drive an object of 40 kilograms to fly. The flight speed is not even as fast as the basic natural wind. If the wind is slightly stronger, it will be over.
As the real No. 1 aircraft, there is no doubt that Flyer One has various flaws. However, looking at the numerical difference, you can imagine that even if it is improved to the extreme, on a fixed wing, 600 watts will not be able to fight other than carrying people. Wind force, after all, is just the minimum force required to withstand a person's weight vertically.
The two are superimposed, and the difference between using the power of the drive shaft and directly using magic to make people go to heaven is more than fifteen times.
From the perspective of magic power, the mechanical team lost a lot first.
Although there has long been a fullerene magic adsorption device to automatically replenish the energy module of the equipment, the production of fullerene is still not an easy task even if it is left to a magician. It cannot be produced like steel. In fact, With regard to the current output, more than half of the products are produced by the military, and the other half must be separately supported for research and production, so large energy-consuming equipment still needs to be considered.
Because the existing enchantment interfered with the aerodynamics of the flying object, it eventually became a big disadvantage, and Dean Xiu also began to lean towards a purely magical solution.
The director's preference is not obvious, but the little differences in cooperation in various aspects accumulate, resulting in that when the magic team prototype can fly, the mechanical team is still tossing around the 1:4 model... Even if it is made at 1:1, it may not be possible. Someone dares to fly.
When His Majesty's decree comes down, everything will be settled.
The single-person flight equipment was also transferred from the experimental model to the official project name, Tornado One.
