Wang Bin and sun Lao first came to the laboratory for the research and development of pulse detonation engine. At the same time, this technology is also the research and development focus of Tiangong technology in terms of new technology.


    After all, compared with ion engine and atomic engine, it is easiest to realize this technology with the current material technology of Tiangong technology.


    Moreover, when Tiangong technology develops a real manned aircraft, it is necessary to start the research and development of aerospace aircraft, and the research and development of aerospace aircraft must use engines that can be used both in the atmosphere and in space. Pulse detonation engine is definitely the best choice for Tiangong technology at present.


    Of course, they can also choose other aspects of engine R & D work, such as variable cycle ramjet, but these engines have complex technology and high technical difficulty, and have very high requirements for processing equipment. The most important thing is that in terms of safety, they are far inferior to pulse detonation power generation, as well as the requirements for materials, It is not lower than that of pulse detonation engine.


    Therefore, now that they have made great achievements in pulse detonation engine, it is not necessary for them to re develop variable cycle ramjet. In this regard, the government has also been developing and achieved good results. If Wang Bin and their Tiangong technology re develop, it will undoubtedly waste funds and scientific research resources.


    You know, with the official approval of the deep space star chain plan of Wang Bin and Tiangong technology, the funds and scientific research resources that Wang Bin and Tiangong technology will invest in the future are very huge, a little waste, which is a great damage to Tiangong technology.


    As Wang Bin, sun Lao and others came to the laboratory, the first thing to see was that there were many pulse detonation engines in the laboratory.


    The diameter of these engines is generally small. The largest diameter of the smallest engine is only less than 50 mm, while the nozzle of the engine is smaller, only less than 20 mm. At the same time, the self weight of this engine is only a few kilograms.


    However, although the diameter and weight of this engine are small, the length of this engine is not short, with an overall length of more than one meter. At the same time, although the nozzle of this engine is also small, its thrust is not small, reaching hundreds of kilograms. It can be said that this engine also has certain practicability, especially when used in small Aerospace unmanned aerial vehicles, Even more so.


    After all, when the ramjet is used in the atmosphere, when the speed reaches Mach 2.2 or above, its fuel consumption will be much less than that of engines of the same level. As for the universe, its fuel consumption is several levels less than that of rocket engines of the same level.


    In addition, there are many types of pulse detonation engines in the whole laboratory. These engines are not the same in size and shape, ranging from large to small. However, the largest of them has a maximum diameter of no more than 1200 mm, and the nozzle diameter is no more than 500 millimeters.


    At the same time, among these pulse detonation engines, the thrust and specific impulse are also large and small. The thrust ranges from hundreds of kilograms to several tons. In terms of specific impulse, there are about ten times that of ordinary aviation engines, and there are also engines that reach more than ten times that of ordinary aviation engines.


    Of course, in addition to these successfully developed engines, there are more failed products in the whole laboratory. After all, even with good materials, it is impossible to develop a pulse detonation engine with excellent performance at one time.


    However, fortunately, with the increase of R & D time for pulse detonation engine, R & D personnel have a more in-depth grasp of various data of pulse detonation engine, and the success rate of its R & D has greatly increased. Until now, they have rarely failed and the engine can not work.


    These engines, except for a few engines, are considered to be truly successful in research and development, such as the five ton pulse detonation engine that has just been successfully developed.


    Other engines, seen by these people in the laboratory, are actually just experimental products.


    "Mr. Wang! Mr. Sun!" just after Wang Bin and them entered the laboratory, the person in charge of the laboratory immediately came up to greet them.


    Wang Bin is very familiar with the person in charge of the new rocket engine laboratory. After all, he is the person in charge of the laboratory, but he appointed it himself. Without the person in charge of the new rocket engine laboratory, it is Jia Jie who was transferred from the mechanical laboratory.


    Although it is said that when he was just transferred to the laboratory, Jia Jie and the people in the laboratory had a very big gap in various professional knowledge.


    But now after such a long time of study, Jia Jie has made great progress in all kinds of professional knowledge. At the same time, he is also good in KM laboratory.


    "Jia Jie! Mr. Sun and I came to see how the project in your laboratory is going," said Wang Bin.


    "Mr. Wang! Don''t worry! The project in the laboratory is progressing very smoothly. We can definitely develop a usable pulse detonation engine within the planned time," Jia Jie said.


    Of course, Wang Bin or sun Lao is very familiar with the R & D projects in the laboratory. After all, these R & D tasks are determined by Wang Bin and sun Lao.


    Now, the ongoing project of pulse detonation engine laboratory is based on their previous research and development results, and the engine with greater thrust, especially in terms of static thrust.


    After all, the previous five ton static thrust was still too small, so Wang Bin and sun Lao decided to carry out the research and development of an engine with a static thrust of more than 10 tons in the laboratory after discussion.


    Although it is really difficult for Jia Jie''s laboratory to directly double the thrust, both Wang Bin and sun Lao believe that with the previous successful experience, Jia Jie and others can definitely develop the engine they require.


    Subsequently, Wang Bin and sun Lao came to the ion laboratory. However, after arriving at the laboratory, Wang Bin and sun Lao didn''t stay too long. Although the ion rocket engine of Tiangong technology, even in the whole world, is already the most advanced ion engine, this is already the limit that Tiangong technology can do at present.


    And this began to be based on the superconducting material technology of Tiangong science and technology. Without superconducting materials, the thrust of ion engine can never reach such a large level, or even the same level as that of other countries.


    At the same time, because the ion engine needs a lot of power in the working process, and the spacecraft is doomed not to carry a lot of power, and the little power generated by the solar panel is not enough for the high-power operation of the ion engine, so if you want to improve the thrust of the ion engine, you should start from the aspect of energy.


    However, the battery of Tiangong technology is already the most advanced in the world, so even if the ion engine continues to break through dozens or even hundreds of thousands of cattle, the spacecraft simply does not have enough power to provide its work.


    After all, it is impossible for spacecraft to carry a large number of superconducting batteries to provide power.
