It is impossible to jump to turbofans. The turboprops currently in preparation are already monsters, and jumping back will cause big problems.
Wang Qi's biggest headache is undoubtedly that there is no microelectronics industry in the kingdom, which is also determined by its size. Like rocket technology, it is also a large consumer of labor and brain power.
Without an electronic control system, trying to operate a turbofan engine is undoubtedly risking your life.
The characteristic of a turbofan is that it cannot achieve high efficiency at low speeds. Its minimum seaworthy speed is high subsonic, which is the upper limit of the turboprop, which is a little higher.
High speed means that compromises must be made on the airfoil, and the wing sweep angle must be increased, developing towards static instability.
The so-called static instability can be understood by referring to the glider. The glider is a typical statically stable attitude and does not require additional power during flight.
In a statically unstable form, after the engine fails, it will either fall down or fall into a tail spin... and land on its butt.
Of course, like civil aviation, you can control the airfoil to a critical state and fly at high subsonic speeds, but this will increase the requirements for all aspects of the entire aircraft.
Regardless of whether it travels at high subsonic or supersonic speeds, turbofan aircraft without electronic control systems are very deadly. A slight gasp or engine shutdown caused by insufficient air intake in the air may destroy the aircraft and kill people.
There is also no electronic control system, so turboprop aircraft have no such problem.
The upper limit of the speed of this kind of aircraft is not determined by the engine power, but by the propeller tip speed. The shock wave generated by supersonic speed in this part will cause the aerodynamic state to change, causing the traction force produced by the propeller to decrease.
Turbofans also have blades inside, so why are they not afraid of supersonic speeds?
In fact, I am also afraid.
The way turbofans are used is to shorten the blade length and increase the number of blades to stabilize the supersonic airflow. Multiple fans are also used to reduce the pressure of a single fan and allow the gas to accelerate and pressurize step by step.
In short, the turbofan cannot be used now, but if some automatic control problems can be solved through magic, it is not impossible to consider.
After coming out of Blue Sky Heavy Industries, Wang Qi took Li Xiangqi Xiong to the research institute again. They were working on new things again.
...It’s hard to say it’s new, because the thing has actually been around for a long time, but it was just taken out and modified for industrial use.
I'm talking about the strong wind type.
The Tornado Type 1, the Kingdom's first aerial vehicle and the only humanoid vehicle, experienced a very brief semi-service state and was returned before it even reached the battlefield stage.
The mining development on the vertical surface of the floating island requires a construction machine that can fly.
Obviously, this kind of work cannot be completed with mechanical equipment. Even if there are helicopters, let alone no helicopters, they cannot be used for direct construction.
The research institute is a confidential department. Industrial equipment will be produced here, and it will be the fault of two civilian aircraft factories.
The manufacturer went to the aircraft factory. When these two companies saw that they couldn't do it, they asked Blue Sky Heavy Industries for advice. After all, their basic knowledge of aircraft and wooden man production technology came from Blue Sky Heavy Industries.
There was no change of hands, and the institute had a team of academicians to help out at Blue Sky Heavy Industry. When I heard this, I suddenly thought of the blast type 1 that was still gathering dust in the warehouse of the manufacturing bureau.
Then a report was submitted from the research institute, and after approval, the manufacturing bureau was asked to hang an additional "Cliff Machine Tool" brand to produce industrial equipment.
Of course, the premise is that it cannot affect the supply of the military.
Then he used the signboard of "Cliff Machinery" to communicate with the original demander, Hongri Mining.
Hongri Mining is a company located in Junkou City. At the beginning, it mainly helped the predecessor of Rainbow Metal, that is, it did the search, identification and import intermediary work for overseas minerals for Fenggu Nonferrous.
Obviously this was a short-lived business. Later, Hongri Mining took advantage of the opportunity of Blackwater's restructuring and became one of the shareholders of Blackwater Minerals, but the share was not large.
It really started to move after the island became a floating island.
The forces in most areas of the exile are based in the lord city. The ownership of resources outside the city mainly depends on whether the force is strong. If you can invite sixth-ring mages or magic swordsmen, you can think of a bigger resource points.
In the early stages of the Phoenix Kingdom, its power radiated for dozens of kilometers along the railway line, and it could not be controlled even if it was further away.
It has evolved from floating islands and completed the new border deployment, and then it can truly cover a total area of 30,000 square kilometers.
There are some villages here that did not cause trouble before and relied on selling local specialties to make a living. Most of the farmers are required to relocate as a whole, and some are mining. Hongsun Mining took advantage of this east wind to stir up troubles, forming a cooperative enterprise to maintain mining villages outside the city... They are not small towns.
There is a suspicion of bullying outsiders, but Hongri Mining is a mineral intermediary, so it is suitable for this kind of work.
Anyway, after doing cooperative mining for a while, they still felt that it was not enough and wanted to open a new mine.
Normal surface minerals have either been mined out or are occupied by powerful people. Underground mineral exploration not only requires very professional people to do it, but it is also very slow. Waiting for ten or twenty years may not yield good results. The best way is It is to fly directly to the uninhabited area for visual search.
The section of the floating island is an uninhabited land that no one has ever set foot on, and it is so close that it is a godsend.
You don’t need to worry about it. If you take the transportation flights of the Dark Land, Wind Valley, and Pangxun, you can see the different colors on the cross section. Just hire a hot air balloon or a flying mage to take a look, and you will start to wonder. It's itchy.
If there is a need, there must be a plan.
There is a traditional method of cliff mining, which is manual rappelling.
Compared with the current situation, most of the high-value mines that normally require manual rappelling are gold, silver, saltpeter and other high-value mines in dangerous terrain. But since it is a natural terrain, the most severe terrain is the sinkhole type, with limited depth, and most sinkholes do not need to be completely suspended, there will be a certain foothold.
After the floating island grows outward in a circle, the angle between the cliff and the horizontal plane is greater than 90 degrees. If you rappel directly, you will be suspended in mid-air. You have to use a swing to find a way to grab the piton nails on the cliff.
This is still the difficulty of the peaceful mode. Considering that the demons will have flying units flying under the cliff at any time, it is necessary to plan how many lives will be compensated before the artificial abseil begins.
Therefore, the equipment must have protective capabilities. It is best to be able to survive for a while when the ropeway is broken...actually it is required to be able to fly. Even considering that there will be a mine at the mining site, if it falls halfway, it must be able to accurately fall into the mine. .
So it was logical to find an aircraft factory, and then there was an industrial restart of the Guangfeng type.
Li Xiang once helped draw a picture of the storm type, which felt a bit like the Onion Knight.
Probably the institute has established a bit of an aesthetic foundation, and it's much better this time, evolving from the Onion Knight to the Canned Knight.
It was Caroline who came to receive the reception. After she finished the introduction, Wang Qi asked: "You are also responsible for this kind of thing?"
Caroline blushed a little and said: "Actually, I am not responsible. I just received the news that His Majesty and the Queen are coming, and asked me to memorize the relevant documents temporarily."
Wang Qi nodded: "I don't eat people. Whoever is responsible will receive it. Actually, I want to say... maybe the appearance can be changed to be more beautiful."
"ah?"
