Share with friends and circle of friends with wechat scanning QR code < / P > < p > recently, the space company Blue origin of Amazon founder Jeff Bezos used modular transportation tools to install the first stainless steel test tank of project Jarvis on the launch pad complex 36 in Cape Canaveral, Florida. The photos show that the component is strikingly similar to the tank on the SpaceX super heavy rocket booster prototype of Elon Musk's company < p > < / P > < p > Blue origin is rapidly promoting the "Jarvis plan", which aims to develop a fully reusable superior for the "new Glenn" rocket. A spokesman for the company said that the test tank may start a series of tests as soon as next month to determine its strength and capacity to hold pressurized propellant < p > although blue origin has not publicly discussed the details of the plan to build a reusable superior for the new Glen rocket, the source said that the company's primary goal is to reduce the overall launch cost of the new Glen rocket. The upper diameter of this launch vehicle is 7 meters. It has two be-3u engines and is expensive. In order for blue origin to compete with SpaceX's starship launch system, making the new Glen fully reusable is crucial < p > the test tank project is an important part of building a reusable superior, and the other aspect is to select and finalize the design of the second level. Both projects operate in the "senior development project department" of blue origin and are making progress < p > "Jarvis program" includes storage tanks, which aims to rapidly prototype propellant storage tanks to withstand the severe test of multiple launches and re-entry into the atmosphere. Blue origin engineers are studying the use of stainless steel as the material for these tanks, just as SpaceX produces starships and super heavy boosters. Stainless steel is cheaper and can withstand atmospheric heating in the re-entry atmosphere, but its weight is about five times that of composites < p > in order to act quickly and test whether SpaceX's iterative design concept can be emulated, Bezos, the founder of blue origin, authorized the engineers leading the "Jarvis plan" to innovate in an environment free from strict management and paperwork processes. This prompted the rapid development of tank research and development and sent it to the launch pad < p > according to the source, at the same time, another team has been studying three different methods of designing and loading aircraft. One is to install a huge wing at the upper level, so that it looks and functions like a space shuttle, separates from the booster and carries the payload, and then returns to the runway < p > the second method involves the use of an aerospike engine that acts as a heat shield when re entering the earth's atmosphere. This approach has great potential, but it may require the design and construction of new engines, which will be an expensive and time-consuming process < p > the third method is similar to SpaceX's starship concept: use a combination of flap and propulsion combustion to land the vehicle vertically. This seems to be the best of the three options. Blue origin is expected to make a final decision before the end of this year < p > however, regardless of the final design, the propellant tanks of the three designs will be cylindrical, which enables the Jarvis project team to continue its development plan. It is reported that the construction speed of this test tank is much faster than other projects of blue origin, which may verify Bezos's experiment with rapid and iterative development < p > a source said of the motto "gradatim ferociter" (Latin for "step by step, forge ahead") of the origin of blue: "Bezos now wants to put a strong emphasis on" forge ahead "in our motto."（ Small) < / P > < p >
