Even though there is a vacuum environment on Roselle and no shock wave, the earthquake caused by the explosion and the flying debris caused heavy damage to the buildings around the laboratory. Even the clones died, more than twenty of them. Not only that, the modular nuclear fission reactor was also completely destroyed, and the nuclear fuel inside was blown away, causing the radiation in the surrounding areas to increase to a terrifying level. Li Qingsong felt a little helpless. He had expected that the first test would be unlikely to succeed, but he had not expected it to fail so completely. "It exploded directly... What went wrong? The strength of the magnetic field should be sufficient, it shouldn't have exploded..." Li Qingsong thought in his mind and immediately organized clones to collect the wreckage, conduct technical analysis, and quickly repair the buildings on site. All the rocks, building materials, debris, etc. that were contaminated by the nuclear power were taken away, and a new layer of floor was laid, and the problem of nuclear contamination was solved. Anyway, there is no atmosphere on Roselle, so there is no need to worry about nuclear pollutants spreading through the atmosphere. On Earth, if an experiment killed more than twenty people and even caused serious nuclear pollution, it would undoubtedly be an earth-shattering event, and the entire project might even be shelved because of it.
But for Li Qingsong, twenty or so clones didn’t matter. This failure did not affect the research of the entire project at all. In fact, not far from here, the second experiment is still underway. After collecting the wreckage and analyzing it, Li Qingsong finally confirmed that the cause of the explosion was not the insufficient strength of the magnetic field constraint, but the excessive pressure that exceeded expectations. The reason for the excessive pressure is that the heating rate of the nuclear fission reactor is not well controlled. The plasmas were heated to too high a temperature and the restraint was not strong enough, so they spread like explosives with their extremely high internal energy, and the huge shock wave directly destroyed the entire facility. "That's a problem." Li Qingsong thought silently: "Maybe we need to add a temperature control device." While this problem was being solved, another experimental base once again experienced an earth-shattering explosion. Failed again. "What went wrong this time? Hmm... the magnetic restraint device is unstable? No, we need to continue adjusting it." Still unable to control the high temperature and high pressure plasma, they turned into bombs again and directly blew up their hiding place. If you want to get higher thrust, you have to control higher energy. And things with higher energy, if they are controlled well, can produce stable output and contribute far more efficiency than before. If it's not controlled well, it will be a bomb that can destroy everything. Fortunately, this is on the surface of Luoshen. If a spacecraft's engine exploded in space, it would be a disaster. Li Qingsong was not discouraged and continued to repeat the repair process and then started the experiment again. For a moment, the various experimental bases on Luoshen Star were like conducting weapons tests, with explosions occurring one after another. Often a base would be repaired and then blown up again within a few days. It would be repaired again, and then blown up again not long after it was repaired. This kind of research method is intolerable in the human world. But it is undeniable that this kind of research method, regardless of cost and input, which exposes all shortcomings through practice, has the highest efficiency. So, after being exploded more than a hundred times, Li Qingsong's newly made secondary pressurization thruster finally stopped exploding.
In order to solve the explosion problem, Li Qingsong summarized, optimized and improved more than 10,000 details during the continuous explosions, comprehensively improved the material performance, improved the stability of the device, and even overhauled the overall structure three times. But, although they no longer exploded, they still did not work properly. Various inexplicable shutdowns, vibrations, voltage instability, overloads, and overheating problems occurred one after another, leaving Li Qingsong overwhelmed. There is no other way. When the enemy comes, we will fight him with our soldiers. When the water comes, we will block it with earth. Often, an engine would inexplicably stop after just a few minutes of operation, and then a group of clones would rush in, dismantle it directly, carefully check every component and every structure, determine the type of fault, and reassemble it after solving the problem. Then, not long after running, it would stop again, and then be checked again, and so on. Moreover, Li Qingsong built not one but 100 such testing sites! 100 testing machines were running and shutting down day and night, and 100 research teams were on duty day and night, not daring to slack off at all. Under such circumstances, three years passed slowly. Laboratory 67. In the vacuum test field, bright blue flames continuously spewed out from the huge nozzle. The even larger engine module, which is composed of three sets of equipment: a fission reactor, a chemical engine, and a secondary pressurization device, has numerous pipes and lines extending from it. One of the lines was connected to a monitor on which some numbers kept jumping. One of them is time. At this moment, it has been moving up little by little from 0:00:00 to 23:58:55. Another number shows its propulsion power. The propulsion power keeps changing, and a curve is drawn. This curve has very little fluctuation and is close to a straight line. When the time finally reached 24:00:00, the slight shaking of the earth slowly disappeared, and the bright blue flame also gradually disappeared. It stopped advancing smoothly. Looking at the extremely stable propulsion power curve in front of him - its stability means that the propulsion output of the secondary pressurization thruster is always stable, Li Qingsong's heart is filled with joy. Three years! After three years of hard work day and night and all-out research, we have finally built the first secondary pressurization engine that can work stably for 24 hours! At this stage, although it is still not mature, it has at least met the qualifications for the next stage, large-scale practical application testing. "Then let's build a batch of cargo ships powered by secondary pressurized engines to carry out cargo flights from Enemy Star to Rosen Star! What hidden dangers and defects this engine has will be exposed as long as the total propulsion time is long enough. " Li Qingsong was too lazy to test, optimize, and adjust them bit by bit like in the human world, until the risks were reduced to the lowest before putting them on the market. Again, actual application is the best way to test an engine. As for the hidden dangers... What hidden dangers? Isn't it just a spaceship? I can blow it up. I can build it!
