After the sudden change in the north, Wang Qi asked Li Xiang to help visit the institute several times. A few months later, he notified the director of the institute to submit a special report to further understand the development progress of "vector generation".
According to this report issued by a special laboratory, the force performance of the "vector generation" on the lander is not particularly good.
The thrust-to-weight ratio of the equipment restored with the original parts is measured to be 10:1, while the thrust-to-weight ratio of the replica is 10.1:1. Based on the information currently available, the maximum thrust-to-weight ratio is estimated to be around 15:1.
The thrust-to-weight ratio is the ratio between thrust and weight, and is divided into two types: the thrust-to-weight ratio of the power part and the thrust-to-weight ratio of the entire machine.
For the thrust-to-weight ratio of the power unit, simply comparing the relationship between the engine thrust and the engine's own weight, the value will appear to be relatively large. The greater the thrust-to-weight ratio, the better the assembly space and upgrade potential of the entire machine.
When the thrust-to-weight ratio of the entire aircraft reaches above 1, it can fly vertically upward without the speed returning to zero. It can achieve excellent flight performance between 1.04 and 1.4, and the diminishing marginal effect will become more and more obvious when it is raised further.
In fact, many aircraft do not need vertical climb capabilities. Depending on the upper limit of flight speed, a thrust-to-weight ratio of 0.8 or even lower is not impossible to fly.
The thrust-to-weight ratio of the "Vector Generation" prototype can reach 10 to 1, which is a pretty good result. In comparison, the Turboprop No. 1, which uses some magic technology, has a thrust-to-weight ratio including propeller weight of only 10 to 1. , the first generation that will later evolve into a turbofan machine will probably not reach this number.
However, it can be seen from this comparison that the performance of vector generation is really not good, and the upper limit is similar to that of a purely mechanical chemical energy jet engine.
Of course, there is no rule that archaeological scientific research must be better than modern equipment. They just have different development lines and have reference significance.
What Wang Qi wants to know is the limits in different directions.
Industrial manufacturing, handicraft manufacturing, and magic tools all have the same performance in terms of size differentiation. They all start from daily-sized tools and then develop towards large and small sizes. Both represent an extreme.
The protective necklaces and bracelets used by nobles without magic are miniaturization of magic circuits. In the hands of individual masters, these things can be made extremely complex, and one piece of jewelry can accommodate many functions.
My own kingdom is limited by the total population, the number of high-end talents, and development time. The path in these two extreme directions is relatively slow. Relatively speaking, the enlargement of mechanical equipment and the miniaturization of magic are slightly better. , indeed it is not extreme enough.
The same goes for the research on "vector generation". The institute has its own theory, which is helpful to miniaturization.
In the past three months, further analysis and experiments have been conducted on the prototype, confirming that the current technology can push the limit of miniaturization, and can reduce the length of the tetrahedron from more than six meters to three meters.
New questions arise.
To put it simply, the shorter the side length of the tetrahedron composed of four components, the worse the conversion efficiency of its magic power and vector force!
Even if energy storage consumption is not considered, the thrust-to-weight ratio will be reduced after miniaturization.
The second trial prototype has a thrust-to-weight ratio of 8 to 1 when the side length is three meters. When the prototype components remain unchanged and the side length is simply expanded to about four meters, the thrust to weight ratio is 8.86 to 1.
It's "around" four meters because that's not an exact value and the device won't work with certain side lengths.
The meaning of "vector generation" is actually a set of magic arrays adapted to large-scale.
But because there cannot be other objects between the four nodes of the magic array, this side length problem is too uncomfortable. The larger it is, the more space is wasted, and space is very precious for things that need to go to the sky.
Even with a side length of three meters, there is too much space for a flying car.
After researching to this point, it is basically certain that it can only be used as a power source for big things like the Flying Fortress.
Wang Qi was given another month's reprieve and began to promote the Flying Fortress plan.
The Flying Fortress is a war vehicle that Wang Qi imagined when he was imagining Little Bear City. Its purpose is to fill the shortcomings of the current air transport capability and deploy heavy fortification-level battle lines at temporary target points as quickly as possible.
It's just that the existing floating and flying energy consumption of this thing is too huge. It takes more than ten days to recharge a round trip with a radius of 400 kilometers. The dispatch rate is very worrying, and it cannot cope with the high-mobility strategy of the demons.
If "Vector Generation" does not appear, the Flying Fortress will also be activated, but it can only be used as emergency border support.
Now that there are new technologies, overseas deployment can be considered. The specific progress will depend on the actual progress of the project to formulate subsequent technical and tactical indicators.
The Flying Fortress development plan has been prepared for a long time, and Wang Qi started to promote it, directly controlling the sacred tree near Huanreservoir West Road to build the first city defense unit.
A city defense unit includes a section of city wall, a battalion-level military camp, an aerial fortress, a supply position, and a dense military area on the inside.
Part of the city wall needs to use the new sacred tree construction model, and artificially add armor plates and fireproof frame layers.
The military camp is not complete in one unit. It takes two units to form a complete facility including vehicle training.
In addition, in order to limit the total size of the troops stationed in Little Bear City, there is also a city defense unit for company-level camps, including the city gate section. There are four versions of the city defense unit alone, which can give Wang Qi a lot of trouble.
Since Wang Qi did not want to distance the army and the people too far from the military-intensive area, it was not just a military-affiliated area. There would also be some low-cost rental houses in it. These rental houses would not be changed until Little Bear City is fully rolled out. Rent for sale.
The most special thing inside is the parking spot of the flying fortress. It can be a simple parking spot, or it can be used as a growth and construction point for the flying fortress. When the fortress is docked, it can be used as an air defense position for the city wall section.
At this stage, the state of the fortress is being consulted by the military department to solicit opinions from all armies, especially the suggestions from heavy equipment defense units such as the 2nd Brigade. It has been updated in two versions, from the early round shape to the current donut shape. .
However, considering the characteristics of "vector generation" power equipment, we may still have to return to the bread shape in the future.
A lot of work has been done before the "Vector Generation" research project. The more difficult part of the preliminary work is not the shape itself, but its deployment bracket.
From the perspective of military operations, placing a heavy fortress on the plain is also a fixed target. Considering that the tactics of the demons will also evolve together, such a deployment point will be very dangerous.
The fortress requires adaptability to mountainous terrain, which places very strict requirements on the lifting structure.
The structure grown by the sacred tree itself cannot meet the needs of adjustment, support strength, and buffering at the same time. Therefore, this set of brackets must be installed afterward. Xincheng Heavy Industry provided the plan and the Locomotive Factory provided early test data.
In order to realize the transformation on the spot, the fortress docking area is a shelf as a whole. When the fortress is parked, heavy trucks with containers can pass underneath it. In the camp mode, the entry and exit of personnel and materials also naturally become under the belly.
But no matter how you prepare, these early actions are just an empty shell. In the fortress plan, the sacred tree part is equivalent to an automatic construction platform, and what grows out is only to provide fixed points for other equipment at the metal level, and even some Some of them will be completely replaced by artificial artifacts in the later stage, and a large amount of work still needs to be completed by research institutions and engineering troops.
Since all aspects have been prepared for a long time, further reports on "vector generation" came out, and Blue Sky Heavy Industry quickly submitted a version of the concept drawing.
The overall layout design of the fortress was completed by a joint team of Xincheng Automobile Factory, Magic Weapons Research Institute, and Blue Sky Heavy Industries. Because the fortress had to fly, Blue Sky Heavy Industries took the lead.
According to this version of the concept map, if the core power device of the "vector generation" can be completed as scheduled, the testing of the first flying fortress can be started within about a year.
