On the grade that enters outer space, each gram weight is very crucial. 6 spacecraft had not flown to new Aliyana even, but development group has issued the rocket with 63 meters tall generation in research. The target is the weight that hopes European spaceflight reduces 2 tons: The weight of the rocket is less, the effective load that it can carry is more. Experts deliver the view to in the class of rocket last stage that will not the plum is developed and be built. It will be become by the design in this century end " of arena of superstratum of black of a " , carbon fiber composite material will replace the metallic structure previously. Researcher says: Every many kilograms effective load can reduce “ emissive cost. ” is in Aliyana 6 second one year is made an appointment with before blasting off, researcher regards European rocket manufacturer as group of A Li Yana (ArianeGroup) not the controller of project of future of Lai plum base leads the " black with very high demand of a technology project of end class " . Whether can this project succeed, want to controlled ability to see 2025. Be as high as 860 tons in view of the gross weight that contains 4 to aid the burden level that pushs a rocket, aliyana 6 end class weight is much still be 2 tons little 2 tons, it is not important to appear at first. However, eventually, only end class and effective load had taken off aerospace. Researcher says: "This arena every become light a kilogram, can increase effective load directly a kilogram. "Since tesla development business and push especially possessory churn with dumping price since international satellite launchs the market, the competition on the road that leads to sky is brutal callosity all the time - looking in European aerospace traveler at least is such. Important is effective load. Had smaller end step, aliyana can carry 13.5 tons 6 numbers and not be 11.5 tons effective load enters the world dormant orbit. Additional effective load is particularly significant to commercial user, come from telegraphic branch for example. Use carbon fiber is not the weight that the metal will come to to reduce basic structure part, make the one part that aviation industry lives daily already. Aerospace engineer also has been handed in with what this kind of material hit for some time. Relevant personnel says: "Use fiber composite material, the freedom of the design is spent very tall, and the join component of need also (like flange or screw) get less much, "He listed a few advantages. However, also a few technologies are challenged - seeking a solution is Phoebus project (the black end class that optimizes highly is archetypal; The " black " here represents black material carbon) key, ESA of European spaceflight bureau entrusts group of A Li Yana to have this project at the beginning of November. Not the level of rocket last stage that Lai Meisheng produces besides engine, still include 3 main parts: The jar of hydrogen of a liquid state and oxygen, and a crust, it is assuming the function of the structure that prop up at the same time. In principle, using carbon fiber to twine hollow body is not an obstacle already. Aerospace company MT Aerospace has relevant experience; Divide other outside, this is located in do not come the subsidiary production aviation of the OHB group of the plum uses carbolic jar, become the Phoebus project partner of group of A Li Yana by right of this one technology. Differ with traditional aviation fuel or olefin, rocket fuel developed business to bring huge challenge to fuel: Liquid state hydrogen is met almost migratory in all material. Rakers explanation says: “ and liquid oxygen has extremely strong aggressiveness, can atttack most surface. Part of these two kinds of fuel also stores fall in extreme temperature: Hydric be in - 253 ℃ , oxygen is in - 198 ℃ . ” falls in such temperature, any material can worsen actually. "Below such temperature, actually material of avery kind of can become very fragile, "Researcher says. Technology and applied material institute are created in Fulaoenhuofu (IFAM) below the help that waits for an orgnaization, aogesibao and do not come the rocket developer of the plum overcame this one challenge successfully apparently. However, researcher does not wish to provide detailed information: "In the final analysis, this is one is used at agglutinate carbon fiber the colophony problem " of the net. Next the test of a few months will show whether this material was achieved up to now the sample place of credit card size made commitment. First, bulk comes to 40 litres " bottle " has been twined and check for 30 litres. Now, the measure that after the staff member that participates in a project is close to step by step, in storage tank the place in building needs. They are accumulating manufacturing diameter to be the experience of 2 meters storage tank at present. Of Phoebus project eventually the target is to produce what a diameter is 3.5 meters to set an example implement. Researcher says: "This is equivalent to the diameter of prospective oxygen canister, receive the diameter that is bordering on hydric canister. "Should demonstrate implement after passing all tests, real challenge just begins. Arrive only in those days, develop Shang Caixi to look at the production industrialization of will hydric canister, the full measure that produces a diameter to be 5.4 meters is hydric coal tub. Spaceflight engineer does not want to throw this level early, this has the background of a deal with concrete matters relating to work: The rocket that all Phoebus component wants to be in the center of German space navigation that is located in Lampoldshausen undertakes comprehensive series checks on testing stand. Researcher explanation says: "Why is this him limitation at the beginning of us namely can be in Aogesibao, do not come between plum and Lanbodehaosen on the part that carries easily. "Fundamental development will be in finished before the bottom 2023. At the appointed time, do not come the experts of the plum also hope to be able to settle issue of the rest pendency. No less than is current 5 end class mixes Aliyana new Aliyana 6 end level is same, remain classical metallic structure, "" of black end class also will assume the weight of effective load, guide its to enter the structure of the rocket. Here, carbon also is the select material makings of stylist. Besides what make by fiber composite material advocate outside bracket, the end level that constitutes by beehive shape structure wraps a layer to will shoulder load. What is the detail of these single elements, and they how interaction, the theme that is the phase of the 2nd project that began 2025. After 3 years, the set production of black end class can begin. "Before this, we can face a lot of challenges for certain, "Researcher believes thoroughly, "But considering advantage, this kind of effort is worthiness absolutely. "
