Hypersonic flight
高超声速飞行
The rockets' green glare
火箭的绿色光芒
A new fuel for jets and missiles is on the cards
一种用于飞机和导弹的新型燃料即将问世
The latest buzzword in the world's aerospace skunk works is "hypersonic". Speed and surprise have always been essential to warfare, and what better way to wrong-foot an enemy than by arriving unexpectedly on his doorstep in the form of an aircraft or missile travelling at Mach 5
世界航空臭鼬工厂的最新流行词是“高超音速”
In that context, a notice posted at the beginning of the year by America's navy, soliciting proposals for a new research project, is intriguing. The project's objective is to "determine a form of boron or a boron-based chemical pathway that leads to implementation of boron in energetic compounds, especially fuels (solid and liquid)". The navy's engineers, it seems, are trying to revive an idea that might make hypersonic flight easier to achieve, but which was tested and then abandoned more than half a century ago. They hope to spice up aviation and rocket fuel with a long-neglected element.
在这样的背景下,今年年初美国海军发布的征求新研究项目建议的公告耐人寻味
Boron, atomic number five on the periodic table, is chemically a "metalloid"— meaning that it inhabits the debatable marcher lands between the empires of the metals proper, on the table's left-hand side, and the non-metals, on its right. Compounds of boron feature in washing powders and cleaning products ("borax"), antiseptics and water softeners, and also as additives in fibreglass, but such roles are humdrum. Boron does, though, burn like billy-o, generating a bright, green flame and releasing about 40% more energy per kilogram than conventional aviation fuel.
元素周期表上原子序数为5的硼,在化学上属于“类金属”——也就是说,它处在金属帝国(在元素周期表的左边)和非金属帝国(在元素周期表的右边)之间的争议地带
In light of this, and of reports by spies of green flames emerging from the exhaust of an experimental Soviet rocket, America's air force experimented in the 1950s with stuff nicknamed zip fuel, which was laced with compounds of boron called boranes. The project was abandoned in 1959, for two good reasons. First, boranes proved extremely dangerous. They are toxic, meaning those working with them need special gas masks. They also ignite spontaneously in air, and may even explode. At least eight people involved in the zip-fuel project died in borane-related accidents.
鉴于此,还有间谍们的报告,他们发现苏联实验性火箭的排气口冒出了绿色的火焰,美国空军在20世纪50年代试验了一种叫做拉链燃料(高型能的飞机燃料)的东西,这种燃料含有硼烷的化合物
