中文导读 以马赫数大于5的速度飞行的超高音速飞机在高空飞行时,飞机表面会产生超高温度,这是限制飞机提速的重要原因之一。而日前中英两国科学家团队发现的一种新的耐高温、高韧性的碳化物陶瓷涂层将助力超音速飞机提速。若民用超音速飞机能够实现,全球旅行时间将大幅削减,在数小时内横穿全球不再是个梦。 A new ceramic material could withstand the heat of Mach 5 and above. FRICTION burns. And the friction of the air on something travelling at five times the speed of sound burns hot. The leading edge of such an object can easily reach a temperature of 3,000°C. Inconveniently, that is above the melting point of most materials used by engineers, which makes it hard to design things like wings and nose cones for aircraft intended to achieve hypersonic velo
