The pulse detonation engine and the plasma engine, two special engines for space, not only have simple structural drawings, but also have various parameters and requirements


    From the performance point of view, it is obvious that they have their own uses


    There are red pens circling around some performance indicators, which requirements and data should be met at least


    These data are very strict with the precision of the processing technology and the quality of the materials, even more stringent than the old american f1119p 100 vector propulsion engine


    Even the domestic f1119p 100 vector propulsion engine can not be mass produced, let alone the higher requirements of the space engine


    This is for the Space shuttle


    Lin Mo quickly began communicating with the left wrist Golden dragon in his mind to search for the right recipe


    Pulse detonation engine (pde) is a new concept engine based on detonation combustion


    At present, it is the only engine concept that can work in two modes


    It can work in both inhaled and rocket modes


    The pressure and temperature of the explosive fuel increase rapidly (the pressure can be up to 100 atmospheres and the temperature can be up to 2000 degrees celsius)


    Therefore, the combustion engine can compress the gas without using the traditional compressors and turbine components, which greatly simplified the structure and greatly reduced the cost


    In addition, because the detonation waves travel very fast, reaching several thousand meters per second, continuous thrust can be produced when the detonation frequency is very high (up to 80100hz)


    If it is used to fly out of the gravity circle, it has a very high cost performance and can climb to a height that even a fighter can''t reach


    The "Aurora" high-altitude high-speed reconnaissance aircraft in the united states uses a pulse detonation engine that can reach the astonishing speed of 7 Maher and can fly recklessly in any country''s airspace to take photos


    The plasma engine is likely to be a special engine for space travel after the pulse detonation engine entered space, using Lorenz force to accelerate charged atoms or ions through the magnetic field


    To reverse drive a spacecraft, the same principle applies to particle accelerators and orbital cannons


    Unlike rocket engines, which consume thousands of tons of propellants in just a few minutes, plasma engines provide relatively little thrust in a given period of time before entering space


    They would be like sailing ships with a downwind, gradually accelerating their flight, accumulating propulsion until they were faster than chemical rockets


    Like the full power, variable specific impulse magnetic plasma engine in Lin Mo''s data, the time to land on mars would be reduced from 250 days to 39 days, more than a month to mars, the solar system can go


    Is it really necessary to start building an interstellar fleet


    Lin Mo stroked his chin


    500 Billion dollars was spent on almost 100 aircraft carriers, enough to ship the Old Mei once and for all


    International space station''s investment cost was more than 100 billion us dollars, and with the current level of technological progress, although the "Mount Bu Zhou" space station was larger, the cost was not necessarily higher


    "Ask him if there is an experimental prototype


    We can take the opportunity to analyze it


    " This information was naturally like a glutton


    It aroused the greed of the Golden dragon, full of lust, after eating and drinking


    The dragon race, which was comparable to a professional miner, had now degenerated into a technology house


    This product is now basically two of the most unshakable supporters


    Anything related to science and technology should be taken home to study


    Any metal that has never been eaten must die with a bite


    "Do you have any test subjects


    " Lin Mo scrutinized the document and looked up at Major general sun


    As an exchange of value principle, Lin Mo could not force the dragon to hand over the alloy formula


    He still took Golden dragon''s idea as his own


    "Look at the test subjects


    This, this is a little difficult


    Wait


    I''ll ask for instructions first


    " Major general sun was in a difficult position


    This level of secrecy was higher, and it was not something that the relevant personnel could not access


    After all, it was impossible to keep Lin Mo here forever to copy the alloy formula


    In order to ensure that the obtained alloy formula met the requirements, he got up and called his superiors


    A moment later, he returned to the sofa and said, "Let''s go


    I''ll show you


    " If it weren''t for Lin Mo''s status as an aviation expert, it wouldn''t have agreed to Lin Mo''s request


    The pilot is the future astronaut, and the aviation expert may also become the future aerospace expert


    It has to be said that Aerospace department has also become a cornerstone of the aviation industry


    A life student put together at least a fourth generation fighter jet


    What he said was enough for the Evil


    God knows how much Lin Mo will grow in the future


    Following Major general sun in the elevator to the fourth floor below the administration building, the seemingly inconspicuous building had a special underground defense structure that seemed to be able to withstand nuclear level eight


    Digging deep and accumulating food, the slogan of the cold war between the east and the west, did not seem to be what many people understood


    It was just a temporary response to the party''s call


    In fact, the real creator of this slogan in modern times was the Aerospace department


    The Chen-pao Island incident on march 2, 1969 triggered a confrontation between the two great powers


    On august 28th of the same year, the washington star newspaper published an eye-catching piece of news, titled "The soviet union wants to carry out a surgical nuclear strike on china


    " The text said: "According to reliable news, the soviet union intends to use medium-range ballistic missiles with nuclear warheads of several million tons of equivalent to carry out surgical nuclear strikes on the important military bases of the country - the Jiuquan and Xichang missile launch bases, the Lop Nor nuclear test base, as well as important industrial cities such as Beijing, Changchun, and Beijing


    " ** He resolutely proposed the policy of "Digging deep, accumulating food, and not seeking hegemony


    " The whole country soon entered the "Preparing for war


    " In the face of war, many enterprises turned to military production, the national economy began to turn to the face of war, a large number of factories turned to the mountain area, the third line with closed traffic, the implementation of "Mountain, scattered, cave" configuration, Beijing and other major cities to dig underground works


    As one of the important bases of Aerospace department in Jiuquan, the 5th Training center directly started the deep excavation project at the beginning of the plan


    Lin Mo followed Major general sun through a long passageway, maybe two kilometers long, maybe five kilometers long, a wide passageway that was almost parallel to four tanks


    It was the same gray cement, with communication cables and power lines hanging on the walls


    Lights that would never go out hung on the top


    I''m afraid that maintaining this underground project also requires considerable investment


    Lin Mo followed Major general sun silently, keeping his mouth shut, staring at the ground under his feet, not looking around, to avoid unnecessary curiosity


    In a place like this, even a cat with 900 lives can still be killed by curiosity


    When Lin Mo passed the security door, he saw soldiers with guns guarding the various nodes, all manual and mechanical operations, there was no possibility of being hacked into by the network


    A large room, about 800 square meters, was extremely empty and could not see a pillar


    The walls were inlaid with honeycomb-like muffled sponge blocks at intervals, so that the sound of walking and talking would not have an unusual echo


    Although I don''t know how deep this place is, it''s not dark or damp at all


    Instead, the temperature is very pleasant


    At the top of more than six meters high, there is a skyhu board made up of led light panels


    "Here we are


    " Major general sun brought Lin Mo into the empty room and stopped


    When he came in, Lin Mo looked at the sign "9d" on the door


    Perhaps there are still many of these rooms, although they are not known for what purpose, just look at the size, used to store soldiers, as a warehouse or as a production workshop, there is no problem


    Such places are also common in the "Dark night" Secret service unit''s underground base


    Usually, this kind of empty place is called a standby area, which means waiting to be used


    Seeing Lin Mo turn around and look around, Major general sun seemed to have guessed Lin Mo''s thoughts and said, "Don''t worry, wait a minute, they are coming over


    The level of confidentiality here is very high


    I don''t have the authority to bring you to the production workshop


    I can only let them bring things out for you to see


    " After a while, two battery-powered vehicles with a wheeled platform slowly drove in from the door where lin mo and Major general sun came in


    Several armed soldiers in digital individual tactical armour blocked the door


    Lin Mo took a look and looked familiar


    Henghai battle defense''s "Dragon guards" enhanced version, which was worn in north america, was more than half the standard version worn by the "Dark night" Henghai battle defense combat squadron


    The Aerospace department couldn''t get Dragon general because the only "Dragon general" experimental tactical armor was currently on Lin Mo


    When the soldiers saw lin mo in "Dragon general" tactical armor, they were stunned


    They had never seen the "Dragon guards" system recognize "Dragon general" automatically


    Almost subconsciously, they thought it was the commander of the underground base


    They saluted lin mo at the same time


    This is due to the difference in the level of tactical armor


    "Dragon general" is obviously more powerful


    "Mmm


    Mmm


    Comrades, it''s been hard


    " Lin Mo waved a Barton military salute and smiled happily


    Major general sun couldn''t help but smile


    This guy really took this place as his own territory


    Several technicians in special one-piece dust-free work clothes jumped out of the car and parked the two wheeled platforms next to Lin Mo and Major general sun


    "V11 pulse detonation engine and vasimr5a5 magnetic plasma engine are delivered and recovered in half an hour


    " A technician sent a folder, even from the production workshop, there was a time limit


    "Thank you


    " Major general sun signed for it, signed it, and winked at Lin Mo


    "Take a look


    "
