After entering the port, more than 60,000 tons of cargo transported in the spacecraft were slowly transferred to the land of Enemy Star by the dual-purpose spacecraft. Except for a few supplies that Enemy Planet cannot produce on its own, all of these goods are large-scale mining equipment. Equipment specifically designed for collecting uranium ore! As secondary pressurized thrusters gradually mature, the demand for fission fuel will definitely increase greatly in the future. We have to plunder Luoshen Star, and we can't let Dishen Star go either, we have to plunder it too! After the cargo weighing tens of thousands of tons was unloaded, various products produced on Enemy Star that had been transported to the port in advance were moved into the cargo ship. After refueling, the large cargo ship started its voyage again, flying towards Luoshen at a speed several times faster than the other cargo ships. Not long after this cargo ship left, a second cargo ship using secondary pressurization thrusters arrived, unloaded cargo again, refueled, loaded supplies, and set out on the return journey again. Spacecraft came and went, and came and went again. The secondary booster thrusters on the latest equipment were tested again and again in this process. Every time the cargo ships return, Li Qingsong will conduct a comprehensive inspection of them in the space port to confirm whether there are any faults and their working conditions.
Under this model, Li Qingsong once again collected a large amount of information and summarized many detailed improvement plans. This went on for a while, and although these new thrusters had frequent minor failures, there were no major failures. This situation did not make Li Qingsong happy, but instead made him a little worried. He does not think that this first generation of secondary boosters has reached maturity. Li Qingsong is not that arrogant. Why should I rush to put it into use? Isn't it to expose its hidden dangers and defects as much as possible so that you can eliminate them in advance and avoid an outbreak when you carry out a large-scale relocation? As a result, only some minor faults, defects and hidden dangers that are not serious are exposed? Are you testing me with just this little thing? Could it be that... this hidden danger or fault is hidden too deeply and therefore cannot be exposed in a short period of time? Li Qingsong thought about it and simply built 20 more cargo ships of the same model and put them into the round-trip route from Luoshen Star to Dishen Star. If the probability of a certain fault occurring is fixed, in order to make it occur, either the running time is extended or the number of runs is increased. There are dozens of 80,000-ton cargo ships going back and forth continuously - even if there are not so many cargoes at the moment, they have to go back and forth. They will not be left idle. Even if they are carrying basic minerals with no timeliness requirements, they have to be fully loaded and keep sailing. Under such circumstances, a situation that Li Qingsong had been looking forward to for a long time finally occurred. A cargo ship suddenly exploded during the acceleration phase, and the entire spaceship was blown into two pieces! Exploded! The spaceship finally exploded! At this moment, Li Qingsong was excited from the inside out. The deep space salvage fleet, which had been prepared for a long time, set off immediately, loaded with a variety of search and salvage equipment and rushed to the site of the spacecraft explosion.
At the same time, Li Qingsong immediately retrieved the real-time operating data of the spacecraft that had been saved, and began to check it one by one, searching for the possible causes of the failure. After working hard for more than a month, Li Qingsong finally identified a deeply hidden design flaw. Unlike the previous minor faults and hidden dangers, this time the design flaw even involves the entire structure of the engine! In order to solve this hidden danger, Li Qingsong even had to overturn more than 70% of the structure of the first-generation engine during the development of the second-generation engine. The hidden dangers were so serious, the faults were so big, and so much energy was needed to solve them, but Li Qingsong did not feel heavy or worried at all, but was full of joy. “That’s what we want… It seems that increasing the frequency of operation and the number of spacecraft are indeed the best options for exposing defects. "Well... we have to keep running! We have to run even if we have to pull the stones!" While busy with the design and development of the second-generation engine, Li Qingsong was also controlling dozens of heavy cargo ships in space to continue shuttling back and forth. Time passed slowly as Li Qingsong waited. After more than a month, the second more serious fault finally occurred. When a cargo ship was about to start deceleration propulsion at the end of the inertial navigation phase, the thruster malfunctioned and could not be started. According to the current route, this heavy cargo ship weighing more than 80,000 tons will directly hit the planet Luoshen at a speed of tens of kilometers per second! "Okay! Is it really exposed?" While Li Qingsong was controlling the clone on the spaceship to carry out the inspection, he also made second-hand preparations. Several tugboats quickly took off, secured the cargo ship with cables, and slightly deviated its course. In this way, it can pass by Luoshen Star without hitting it. After the imminent crisis was resolved, more clones came into space with more equipment and began to inspect the cargo ship directly in space. After a busy period, Li Qingsong finally discovered that the source of this major failure was actually a small gasket. The gasket was bombarded with high-energy radiation for a long time, and its molecules changed, and its properties also changed unexpectedly. It was originally non-conductive, but it could conduct electricity under certain special circumstances, which caused internal disorder in the engine, leading to malfunction and eventually failure to ignite. This also portends a worse possibility. If this gasket will undergo this change under severe working conditions, what about the rest of the components? "This is another extremely hidden and serious hidden danger. Fortunately, I discovered it in advance. Otherwise, if it erupted when I officially started the migration, then..." Li Qingsong was full of relief. He directly checked the tens of millions of parts that make up a secondary booster thruster and found all the parts that might have failed due to the same reason. Once the hidden danger is found, there is nothing to worry about and you can just solve it. In this way, after two more serious failures occurred in succession, finally, no failures of the same level occurred for a full six months. Li Qingsong then finalized the drawings of the second-generation thrusters and immediately put them into production. This second-generation secondary pressurization thruster not only solves all the hidden dangers and faults of the first generation, but also has a smaller size and mass, and a higher comprehensive fuel utilization rate! The thrusters of the original cargo spacecraft were simply removed and replaced with new ones, and a new round of large-scale testing began again.
After two years of testing, Li Qingsong finally confirmed that this second-generation secondary pressurization thruster is truly stable. Then...it's time to go.
