The exploration expedition team was first used to explore for primary minerals. Later, its main function became map surveying, and the work of prospecting was not left behind. With the increase in the number of subdivided businesses such as minerals and animal and plant specimen collections, the scale has become larger and larger. Now it has become a staff A team of over a thousand people.
The team's headquarters was transferred to Nanzhen, next to Blue Sky Heavy Industry, so that it can share some security resources and provide Blue Sky Heavy Industry with aircraft development and improvement suggestions through use experience.
Wang Qi and Li Xiang's arrival was notified, but there was no big scene. Only about twenty people came to greet them, and most of them were immediately dispersed, leaving a few leaders to guide them and introduce the situation.
Then the group entered the analysis room.
This is the expedition team's own mineral analysis room, which is divided into a working area and a sample area. Now there is a small model of the ruins in the middle of the sample area.
"Following His Majesty's order, we accelerated the excavation progress and have now opened the gap behind it." The captain pointed at the back of the model with a small stick. "After analyzing the damage here, we believe that the porthole was cracked due to the compression of the ground. expand to form.
The rear compartment of the damaged area has been demolished according to His Majesty's latest order. The internal condition is good. Some modules have been successfully removed and they are temporarily placed in an airtight cabinet. "
Air-tight devices are necessary equipment for mineral research, because some deep objects will undergo surface changes to some extent when exposed to oxygen. Using air-tight devices instead of vacuum or inert gas protection for transfer and storage can relatively reduce additional influencing factors.
"Did you find the engine?" Wang Qi was more concerned about this matter.
The captain shook his head: "No object suspected of being an engine has been found. The power should be a magic variable kinetic energy device. We can't make a conclusion now."
The magic variable kinetic energy device is not a new thing. Its predecessor is the magic lift module used by aircraft. This means that the power of this lander is in the same level range as the "emergency take-off and landing assist device" currently used by our own aircraft, even if it is stronger. Strong to a limited extent.
Of course, the specific results will depend on the conclusion of the device analysis.
Without disturbing the work area of the analysis room, the group went out and moved to another room.
The work here has just stopped, and the sawdust has not completely settled. Take them to the analysis room first, probably to try to use magic to clean it?
In the middle there is an anatomical model of the lander covering an area of more than ten square meters. It looks quite good and has a lifting body structure. Its characteristic is that the longitudinal section of the entire aircraft is more like a wing section, the belly is relatively flat and there is a smooth curve in the north.
As for the specific structure, the top view of the fuselage is roughly in the shape of an isosceles triangle with a vertex angle of 30 degrees.
The advantage of the lifting body is that it has a high lift-to-drag ratio and strong self-stability. It is relatively fuel-efficient when driven by fuel. The disadvantage is that it is difficult to control. The main control surface is too far behind the pot, and it is not flexible enough to turn up, down, left, and right.
Magic power is very effective in solving the problem of lifting body rudder efficiency, and the combination of the two is very appropriate.
There are also many types of lifting bodies. The ruins model shows that its head is relatively rounded, and the blunt-edged acute-angled triangle is a typical spacecraft lifting structure, which can effectively reduce the temperature of the front end.
When the wings stand up, it looks like an object with only double vertical tails. The joint between the wings and body transitions in a smooth arc. There is also a gliding wing on the two standing wings, which is very strange.
Wang Qi didn't know if this combination was easy to use. Intuitively, the joint between the gliding body and the vertical wing surface was not round enough, and the heat would be very serious - assuming it was actually flying through the atmosphere.
In terms of internal volume, the lifting body is also more usable than the traditional ship-like fuselage. For example, the length of the ruins represented by the model is only slightly larger than that of the Manniu, but its widest point can fit ten seats in three aisles, while the Manniu can fit in a single fuselage. There are four aisles.
The damaged part of the ruins is located at the back of the middle section, and the area directly connected to the damaged part is very severely mineralized and petrified. Under such circumstances, Wang Qicai ordered the demolition of the tail section compartment to advance the analysis progress.
The tail section of the on-site model completely restored the layout before disassembly.
"The largest two sets of tanks here contain hydrogen and oxygen. The other equipment is not particularly large. The most likely power plant is this group." The captain said, pointing with a small stick to the same vertical surface evenly There are four things distributed up, down, left and right. "Preliminary inspection found that there is a lack of magic source, and we are investigating it from other components."
Although the ruins are very old, the gas storage conditions can be inferred through the material properties and container shape, and there are not many options left.
Take hydrogen as an example. Hydrogen atoms are extremely small and are prone to tunneling effects. The macroscopic manifestation is that hydrogen will partially dissolve in the steel or even escape directly, and part of it will get stuck in the steel in a molecular form, causing internal stress and causing micro-cracks. It is hydrogen embrittlement and causes permanent damage to the container.
It doesn't matter even if hydrogen embrittlement is not detected, because of the characteristics of hydrogen, completely eliminating hydrogen embrittlement means that the material composition of its container will be completely different from other gas containers, making it easier to detect.
But having said that, a tank that can perfectly store hydrogen can store other gases, but not vice versa. If the containers in the ruins are all of the same model, it will still take some luck to complete the inspection. However, the situation encountered before us showed that the "alien" did not have such high technical capabilities.
Wang Qi nodded: "Thank you for your hard work. Next time, we can slow down a little, let everyone pay attention to rest, and restore their technical ideas as comprehensively as possible before considering entering the front cabin."
"yes!"
After Wang Qi came back, he advanced the progress through orders. There was only one thing he wanted to know - whether it could fly out of the atmosphere.
This question can now basically be answered with certainty.
First, its outer elements are mainly tungsten and niobium. Among them, niobium has a small thermal neutron cross-section and has excellent high-temperature stability. The melting point of tungsten is the highest among others.
The second is that this rounded and smooth appearance and its internal compartment structure are a bit far away from the needs of flying in the atmosphere. The blunt-edged acute-angled triangular shape performs poorly in both the sonic and subsonic speeds. Only superb Only with the speed of sound can you show your strength.
The third is the tank in the tail cabin. These tanks are not needed for normal atmospheric flight, but it is different when placed in outer space. Hydrogen and oxygen can be stored separately and can be used for reverse electrolysis reactions to generate stable electricity and synthesize water resources at the same time. Probability itself is a link in the water cycle system.
In addition, sampling of the outer wall has now been completed, confirming that its structural safety is much greater than the requirements for atmospheric applications. However, this is not particularly strong evidence, because it is not yet known when it existed, and what the atmospheric environment of the exile is like. For the time being, we can only Consider side evidence.
The conclusion cannot be said to be flawless. For example, the gliding body on the vertical wings of the lander is very strange.
The gliding body is shaped like a boomerang. Like a glider, it has a very good lift-to-drag ratio at low speeds. A normal aircraft has a gliding body on its vertical tail, which is the horizontal tail.
However, the overall appearance of the relic lander is closer to that of a spacecraft. It enters the atmosphere at dozens of times the speed of sound, so carrying this thing is a burden.
When a lifting body spacecraft enters the atmosphere, it should fly with its belly facing the direction of momentum to maximize the use of the resistance of the thin air in the upper layer to slow down. Otherwise, it will reach a certain height more than ten times the speed of sound, and the results will be catastrophic.
There is a gliding body at the rear and upper part, which will automatically lower the nose of the aircraft when it enters the atmosphere. While decelerating, the aircraft will not be heated evenly.
Of course, Wang Qi is just talking on paper at this time. On the one hand, he has not determined whether it has a magical aerodynamic solution. In addition, whether this shape is good or not, he has to build a hypersonic wind tunnel to try it out.
... We haven't even touched the edge of supersonic aircraft yet. There are no wind tunnels with 1 to 3 times the speed of sound. It is a bit far away to consider experimental equipment with 20 times the speed of sound.
