Blue Sky Heavy Industry is a comprehensive organization for R&D and manufacturing of aircraft and engines, and the development process requires close attention to various domestic technological updates to ensure that the expected indicators are timely.

They soon caught their attention when the motors started to be mass-produced. Coupled with the recent technological breakthrough of the institute's magic power conversion module, these guys naturally thought that "motors can also be used as engines."

Compared with internal combustion engines, the advantages of electric motors include: more linear power adjustment, outstanding maximum torque, small vibration, and easier volume power density.

The disadvantage is that it is easy to use when connected to the power grid, but the energy density of the battery is too low and is not suitable for the motor to take advantage of it. When used on an airplane, it is impossible to carry an internal combustion engine to generate electricity.

Therefore, the electric motor-type flight engine must correspond to magical energy.

After Wang Qi read the "Development Direction Expectations", he also felt that something was coming.

Magic power is now free energy that costs no money. It cannot directly create kinetic energy. After converting it into electricity and handing over the work to the motor, the situation will be better.

When the motor is working, the rotor can be regarded as a suspension relative to the stator, which is also the fundamental reason for the high kinetic energy conversion rate of the motor. A sufficiently high conversion rate means that the heat produced with the same power is smaller. An air-cooled internal combustion engine can dissipate 400 kilowatts of heat.

This will become a headache. Motors with up to 600 kilowatts can be placed directly on the ground for use. There is no need to consider the additional heat dissipation caused by wind speed. The size is also more advantageous than internal combustion engines.

Magician-driven aircraft can be regarded as the most feasible alternative to glider aircraft so far.

The magic glider aircraft has many problems whether it is used to transport cargo or passengers. However, because it is the only aircraft that can achieve near-zero operating costs and consume no fuel, it is the most popular aircraft in the era of floating islands.

It's certainly good to have the opportunity to upgrade them now.

The expectations don’t need to be too high. Raising the existing average cargo gliding flight speed from 130 to over 200 will greatly improve the transportation capacity.

Wang Qi checked the motor information of Heavy Industry just to see if the basic technical skills were sufficient.

In addition, we also need to look at the energy density of the manufacturing bureau’s magic energy storage module and whether it can meet the basic cruising range requirements.

If you don't mind iterating, you can get started with one or two hundred kilowatts.

But the mission of Blue Sky Heavy Industry is very important, and the production and development of such motors and engines should not even be left to them.

Wang Qi checked the motor testing of Heavy Industry and then checked the files of Phoenix Power Grid.

There is the largest generator here in the country. A single unit has reached 20 megawatts, which seems to be a lot. However, the evolution speed of steam turbines is faster than that of generators. Recently, in line with the expected increase in electricity consumption brought about by the mass production of motors, a unit was built.

One drags six.

The generator can be said to be the culmination of many years of work by the motor factory, and it can better represent their reliability level than the small motors that have recently begun mass production.

From the perspective of the power requirements and working logic of the aero-engine, the final power-to-weight ratio will be between the generator and the small motor, leaning more toward the generator side.

The total weight of a 20-megawatt generator is 21 tons. If the proportion of the base is reduced a little, the power plant should be able to build a 500-kilowatt, highly stable motor with a total weight of less than 500 kilograms.

In terms of weight, there is no advantage compared with air-cooled radial engines of the same power. It would be great if it could be reduced to about 350 kilograms.

It’s not impossible to do what you have in front of you.

Comparing the fuel system, even if the magic power density cannot be increased too high due to concerns about the safety of the magic module, the total weight of the two systems is almost the same.

According to the expectation of increasing the speed of the glider to 200 to 300 kilometers per hour, the power of 500 kilowatts and the existing propeller design capability can pull a 4 to 5 ton aircraft into the sky without magic. Deducting the weight of the system, it can still make the glider fly.

The existing gliders have been modified to increase their transport capacity.

This increase in transportation capacity can be manifested as transporting more high-density cargo, or it can remain at the original level and only increase the flight speed.

After confirming that the basic capabilities in all aspects were sufficient, Wang Qi first wrote a letter to Blue Sky Heavy Industry, explaining that the things would be made by other factories, and then asked the Ministry of Industry to coordinate.

The process was very fast, and the project planning was completed within half a month.

The new motor and engine will be handed over to Hongshi Speed ​​​​Car Factory for final assembly!

Wang Qi was a little dumbfounded when he saw it and didn't know how he could give it to them.

"Your Majesty, the flying car uses a pulse engine. When it is turned on, everyone is really unable to bear it. It is better to change to a propeller solution. This motor engine comes at the right time." The industrial commissioner explained.

"...can it work? Can't you turn a flying car into a plane?"

"It won't turn into an airplane. We asked engineers from Blue Sky Heavy Industry to do some calculations. The shape of the tail of the flying car can be slightly adjusted so that the propeller can be installed at the back."

"Rear-mounted? Okay."

The purpose of equipping an executive flying car with a pulse jet engine is for escaping when necessary. In comparison, the linear acceleration potential of a rear propeller will be much smaller.

The power utilization rate of rear-mounted propellers is actually higher than that of front-mounted propellers, which is beneficial to increasing speed and reducing fuel consumption.

Existing reconnaissance aircraft do not use it because the take-off and landing attitude when the propeller is rear-mounted is very poor, the landing gear layout is weird, and military aircraft require emergency gliding and landing when all power subsystems fail, and the two are completely incompatible.

There is no such problem when it is placed on a flying car, because the flying car originally only has a single magic power. Once it fails, it will fall down like a weight. Taking off and landing are vertical movements without posture. Putting the propeller in front or behind will not cause the problem.

Is it safer or more dangerous.

In terms of speed, no matter how reliable the propeller is, the maximum speed can only reach around 700 kilometers. It is too difficult to build a propeller as big as the tail fortress of the flying car, and the actual speed will be even lower.

Of course, if it is feasible, you can also use magic solutions to make some compensation.

Wang Qi looked back at the report and found that they had already considered the size of the rear propeller when forming the team, and the motors and engines would be directly divided into two models: A and B.

The tentative target for both models is 300 kilowatts. The difference is only in the engine casing, propeller and transmission. It is mainly to reduce the burden on the development and production work of the motor factory. It is tentatively planned to use a single engine for flying cars and gliders.

The renovation required two units, which was larger than Wang Qi's estimate.

The Flying Car Factory is mainly responsible for production and engine debugging in this project, and has no R&D part.

The subsequent design and optimization of the motor, engine and corresponding propeller, as well as some wind tunnel, test bench, and flight test work, will be sent to the Xilukou Aircraft Design Institute, which can be regarded as the hands-on work before the institute starts the Turboprop One, and the team will be run-in.

The aircraft design institute is more than halfway through its construction and will be put into normal operation when the gate to the devil world closes this time.

Something happened at this time.

About Elena.

After the old lady retired from her post as steward of the inner court, she wandered around the country for a while, and finally chose to settle in the new city. She may have kept a low profile, but she was not targeted by bad guys.

After settling down, Elena started a private nursery. This kind of nursery was run in private houses, and there were only 2 to 10 children at the same time.

The old lady completed her life's journey the day before yesterday, and as required by the local municipal government, she sent the news to Wang Qi's desk with an urgent document.
Chapter completed!
