19世纪的欧洲军界不仅见证了康格里夫火箭的兴衰,同样也目睹了几位杰出的发明家将意大利人乔阿内斯·德·丰塔那有关火箭鱼雷的设想付诸实现的努力。严格说来,丰塔那并不是最先提出这种想法的人。早在1410年,简·弗鲁瓦萨尔的编年史就粗略描述过英法百年战争期间出现的一种从发射管发射的军用火箭的设计,不过这只是文字记录。在丰塔那完成于1420年的军用火箭写生集《战争器械之书》中,第一次出现了这种火箭的设计草图。当然,以15世纪时的科技水平而言,这样的设计就像达·芬奇的很多天才设想一样,只是无法实现的梦想。直到18世纪末19世纪初,伴随着工业革命带来的技术飞跃,丰塔那的梦想终于有了实现的可能。
The nineteenth-century European military community not only witnessed the rise and fall of the Congrential Reactor, but also witnessed the efforts of several outstanding inventors to bring the vision of the Italian Qiaoanes de Fontana to bear on torpedo torpedoes . Strictly speaking, Fontana is not the first person to come forward with this idea. As early as 1410, Jane Frevalsall’s chronicle roughly described the design of a military rocket fired from launch tubes during the centennial war of Britain and France, but this was a mere transcription. The first draft of such a rocket appeared in Fontana’s 1420 book of war rocket sketches, Book of War Equipment. Of course, by the technological level of the 15th century, such a design is just like many gifted imaginations of Leonardo da Vinci. It is just an impossible dream. Until the late 18th century and early 19th century, with the technical leap brought by the industrial revolution, the dream of Fontana finally came into being.
