前不久,美国太空总署埃姆斯研究中心内不时传出雷鸣股的轰响。这是工程师们在进行一种新型火箭发动机的点火试验。这种火箭发动机的新奇之处,在于它所使用的燃料是一种硬质石蜡。这些石蜡将成为世界上最廉价、最安全、最环保的火箭燃料。石蜡是一种饱和烃。不同的是,戊烷分子含有5个碳原子,而硬度较大的石蜡分子中则含有25至30个碳原子,作为火箭燃料的石蜡虽然与生日蛋糕上的蜡烛颇为接近,但并不过错全相同。它包含少许炭黑,还加入了一些其他的添加
Not long ago, from time to time, the NASA Ames Research Center reported the thunderous ring of thunder. This is an ignition test conducted by engineers on a new type of rocket engine. The novelty of this rocket engine is that the fuel it uses is a hard paraffin. These paraffins will become the cheapest, safest and most environmentally friendly rocket fuel in the world. Paraffin is a saturated hydrocarbon. The difference is that the pentane molecule contains five carbon atoms, while the harder paraffin molecule contains 25 to 30 carbon atoms. The paraffin wax used as rocket fuel is quite similar to the candle on the birthday cake, but it is not wrong. All the same. It contains a little carbon black and also adds some other additions
