Wang Qi naturally nodded his head when it came to the relaxation of information about jet engines.
The research on this thing will become more complicated as it goes forward. Blue Sky Heavy Industry wants to consider both the turbofan engine and the turbojet engine at the same time. The difficulty is too high, the time period is too long, and it is not conducive to technology iteration.
Therefore, when Wang Qi asked relevant departments to promote the construction of the aircraft design institute, he issued a notice to guide private forces to gradually move towards the development route of turbofans.
The turbofan has two inner and outer ducts. The outer duct does not ignite and can use the hot and cold mixed airflow to generate some thrust. The amount of wind in the duct can also help control the temperature of the inner duct. The technical line is based on the Turboprop One, and there are basically no particularly big obstacles. The next step is to shrink the front propeller and stuff it into the engine hood, and then optimize the shape and material of the fan blades from generation to generation, and try to increase the fan diameter.
The advantage of the turbofan technology line is that the combustion operating temperature can be controlled to less than a thousand degrees with technological iterations, the material technology requirements are relatively low, and the overall life is long. With the blessing of magic, the full life span can be tens of thousands or even tens of thousands of hours. Hopefully, of course the turbine blades will need to be replaced several times in the meantime.
The disadvantage is that the turbofan is affected by the large fan area and the upper speed limit is not high enough. The larger the fan, the more fuel is saved. At the same time, due to the influence of resistance and the loss of fan blade tip performance, the speed will be reduced. The advantage range of working at an altitude of 8,000 to 10,000 meters is Between 700 and 950 kilometers, magic may be able to make some additional contributions, but the bottleneck of the sound barrier is too powerful for the fan, and no known materials can cope with it.
Turbojet is the only way to achieve supersonic speed. As for the rotating pulse explosion engine behind, I can't even think about it now. I will consider it after flying out of the atmosphere.
The fuel efficiency of this line is very poor compared to fans, and its upper limit of single thrust is not as good as that of fans. In order to make up for the power disadvantage and respond to some emergency air conditions, its operating temperature will be higher, and its lifespan is insignificant compared to fans. , the simple life indicator can be improved by 200 hours in one iteration, which can be called a leap forward, and the overhaul life of 1,000 hours is quite cutting-edge.
Due to various disadvantages, in a period when most of the fuel relied on cross-floating island transportation, there was no need to consider the civilian prospects of the turbojet line, so it could only be developed by Blue Sky Heavy Industry.
This is the situation. It is still early to decentralize part of the Turbojet One technology. At least we have to wait until the next generation turbojet prototype testing stage before considering it.
The development of turbojet, regardless of detailed configuration changes, simply means increasing the number of turbines.
The most basic model given to the students only has a cone-like turbine at the front and rear.
The number of turbines in Turbomachine No. 1, divided by combustion chambers, is five in the front and three in the back.
When it came to the turboprop No. 2 adapted to single-engine reconnaissance aircraft to eliminate wake turbulence, while changing the duct structure, the number of turbines returned to two in the front and one in the back, and the shape of the subsequent turbines was closer to the basic type.
The pre-researched turbojet based on the Turbojet 1 has increased the number of turbines to eight in the front and four in the back. Some results have been achieved, but the expected results at this stage are not satisfactory. It can go supersonic, but it is expected to be only Barely breaking through the speed of sound, the specific value will have to wait until the transonic wind tunnel of Blue Sky Heavy Industry is completed.
In fact, Turbo One still has potential to be tapped, such as lowering the temperature of the combustion chamber to lower the material threshold. However, in order to adapt to the speed of change in the world, it has stopped subsequent development after more than two years of improvements to eliminate most of the sources of faults. , and then wait for the right time to pass it to Xilukou Aircraft Design Institute as the entry point for the fan engine.
The turbojet generation of eight in the front and four in the rear will probably be purchased in a relatively small batch like the Tornado II in the future, providing a reference for the subsequent development of engines and aircraft structures.
The route further down has been decided, with the number of turbines being 12 in the front and 5 in the back, and 17 in the front and 5 in the back.
The focus is on the middle section, and the front 17 or 19 turbines at the back, which have limited help in increasing the speed and thrust limits. They mainly focus on improving the working life and guaranteed performance across speed ranges and different flight environments. Considering the difficulty of research and development, Maybe a few more iterations at intermediate levels.
Of course, the first turbine has not yet been tested. It is hard to say how many years it will take for these things to be put into use in the future.
.
Back in the palace area, Wang Qi was checking the latest reports on the two demon gates and the human camp in Area 45.
We are old acquaintances at the Demon Realm Sect in the Northern District, and we had some discussions with a group of suspected novices earlier.
[In view of the general environment,
At this stage, the ecology of the demons in Area 05 has changed slightly. It is roughly estimated that the previously small number of Goma has accounted for one-third of the observable demons.
Goma has the same skills as Little Devil, but there are two differences. One is that Goma has a higher magic power endurance, and a few individuals can release more powerful fireballs that threaten farther distances. The other is that Goma has higher intelligence and can naturally They form groups that resemble primitive tribes and build earth walls, stone fences, and semi-spherical stone houses.
Their number has increased, forming some large and small primitive villages in Area 05, and they have been able to withstand the attacks of some low-level demons.
The staff judged that there was no need to pay attention to it.
As early as before the floating island transformation started, a round of city building fever broke out in Area 05. At that time, it was dominated by the intermediate demons. The air force was watching and throwing some explosives, and the intermediate demons dispersed and disappeared. Follow-up.
The situation in Goma is different. Their small village is too simple. If it is blown up, it will be rebuilt in two days. In addition, this kind of village cannot bear the functions of trade, information exchange and military gathering of various groups of demons. Therefore, Just leave it alone.
As the proportion of Goma in Area 05 increased, the Air Force found that the ooze-like demons that helped Goma move across the island seemed to have also increased. However, the camouflage of this thing was too good, and it could not be identified in space and time without using skills.
I asked about Camp 301 and the POW camp, and everyone knew them, but no one could name them.
What is known is that the little devils will eat this kind of ooze... Of course, there are very few living things that they do not eat, and they will be specially mentioned, because this thing is a common factor in the conflict between the little devils and Goma. If an area Without the ooze monster, the little devil would not take the initiative to attack Goma, who had certain fire resistance.
Goma seems to be able to use small ooze monsters to make pillows, but it's unclear whether it has other uses.
It is basically certain that the ooze monster and Goma have a certain symbiotic relationship, so Goma will try to protect the ooze monster when he can.
This information is of no use to the kingdom. The problem now is that the ooze monsters have the ability to camouflage, and coupled with the influence of the stinky fish in the air, it is difficult to determine their distribution status.
If there are too many ooze monsters, the Air Force will have no choice but to stare blankly the next time it conducts a large-scale cross-island operation.
South Line Demon Realm Gate - Area 2-11, more than a month after the gate was opened, the group movements of the demons were still not captured. It may be because there are too many ice-crown demons on the floating island.
The activity area of the Ice Crown Ice Demon Center is an area that should not be entered by demons with brains. Their reactions must also be considered in group operations. If they die without even rushing out of the ice demon area, the entire operation will be ruined. It just doesn't make sense.
Therefore, the spread of ice demons on the southern line has actually increased the difficulty of decision-making and actions for the surrounding lords on the demon side.
However, it is still necessary to maintain a certain frequency of reconnaissance to prevent the large-scale spread of demons from affecting the size of the foreign trade market.
The people of the Church of Light in District 45 have not made any big movements recently. It can be basically concluded that they are waiting for the main world gate to open again.
The main world gate missed a cycle and was directly replaced by the second demon world gate. This was probably the result of some method used by the demons.
If this judgment is true and the demons can really occupy the magpie's nest, there is a high probability that the overall war intensity in the penal colony will accelerate.
This is a simple strategic judgment - since the penal colony is a battlefield, whichever side controls it can gain a certain strategic initiative.
However, judging from the situation at Gate 2, the location of the Demon Realm Gate on the Demon Realm side does not seem to be particularly controlled, and there is still uncertainty about the future development of the situation.
