Place in “ to wish spark of ” of date of be in harmony to be challenged before the car, very arduous. The task whether successful, depend on the structure of car of spark of ” of date of “ Zhu Rong and structural data, so what material is does for “ Zhu Rong date ” escort the Emperor convoy? Does “ wish date of be in harmony what composite material ” used? In “ black inside 9 minutes of ” , the shooting star is general the touchdown that high speed drops implement, with attrition of Martian aerosphere high speed, land implement exterior temperature lifts quickly, if do not undertake defending effectively, do that Liu Qi is faced with in aerosphere by the danger of burn down. So in the respect that prevent heat, does “ wish date of be in harmony what data ” used? ★ successive fiber increases in density prevents hot composite material: The fluctuation margin that uses in need to keep detector whole figure and structure support position. Action: This data phase compares low density data its intensity is higher, density is 0.9g/cm3 about, give attention to two or morethings be able to bear or endure ablation and carrying capacity. Study a group: What academy of carrier rocket technology belongs to spaceflight material and craft institute. ★ exceeds the ablation that pledges gently to prevent hot coating composite material: Application heats in pneumatic relatively assuasive back overspreads place. Action: Density of material of this graph layer is 0.28g/cm3 left and right sides only, thermal conductance is low to make an appointment with 0.06W/m ﹒ K, its heat up physical function basically to achieve international advanced level, not only heat proof quality is good, also had main effect again to Liu Qi's decreasing. Study a group: What academy of carrier rocket technology belongs to spaceflight material and craft institute. ” of date of “ Zhu Rong bore the weight of multiple task, the equipment that carry is more, still need to endure black of the “ when landing 9 minutes ” test. Quantify a requirement because this is right gently very tall. In addition, martian environment indentation of complex, surface is densely covered, increased more difficulty to land. To ensure “ Zhu Rong date ” is in spark to express success to realize soft landing, used light quantify reach special type composite material. ★ special type sucks high can alloy: Apply at landing orgnaization. Action: This alloy is had outstanding obdurability, light qualitative sex and suck can quality, the concussion when absorbing detector to land can. Study a group: Academy solid physics studies science of material of Hefei of academy of sciences body place. ★ aluminous silicon encloses crust: Application lands at detector the core such as TR component of the system is crucial yuan parts of an apparatus encloses a solution. Action: Safeguard detector lands the safety of systematic circuit, for interior of parts of an apparatus circuit put on the “ of on the safe side to protect garment ” , safeguard detector lands smoothly in Martian safety. Study a group: Hefei emperor amounts to electronic science and technology industrial limited company. ★ high-powered carborundum base enhance aluminium radical composite material: Use at instrument of detector tall nicety. Action: New-style carborundum base enhance aluminium radical weight of composite material component the dimension below limits of tall, rigid good, wide temperature stabilizes light, intensity, the material demand of crucial to some orgnaization when satisfying “ to wish date of be in harmony ” moves for long. Study a group: Metal of Shanghai traffic university base Zhang Di of composite material key laboratory, Ouyang Qiubao teachs a group. Alloy of lithium of ★ new-style magnesium: Use at detector structure. Action: As go up at present light metallic construction material, can realize detector light quantify.
