美国宇航局已设计了碳-碳副冀段并计划评定这一技术究竟能否用于国家航天飞机一类的超音速飞行器的控制面,之所以选择新型碳-碳材料用于副冀试验规划是因为它非常适合于诸如必须承受3000℉高温的超音速飞行器的控制面之类的防热结构的制造。现设计的副冀在飞行时不加冷却,利用迎风面和背风面的热幅射,保持其温度低于或等于3000℉。
NASA has designed a carbon-carbon secondary segment and plans to assess whether this technology can be applied to the control plane of supersonic aircraft such as the National Space Shuttle. The reason for choosing a new type of carbon-carbon material for the pilot program Because it is well-suited for the manufacture of heat-resistant structures such as control surfaces for supersonic aircraft that must withstand high temperatures of 3000 ° F. The secondary wing, which is now designed, is not cooled during flight and uses thermal radiation from the windward and leeward surfaces to maintain its temperature below or equal to 3000 ° F.
