100年前,美国科学家罗伯特·H·戈达德(Robert H.Goddard,1882.10.5-1945.8.10)研发的液体燃料火箭技术,为人类登陆月球铺平了道路,从而开启了太空飞行的时代。作为现代火箭推进之父的戈达德,共获得214项专利(83项专利在他生前获得),其中两项专利非常重要,第一个是液体燃料火箭,第二个是多级火箭。前者可以将一定质量的载荷送入地球轨道,后者在发射后逐级分离以实现质量降低,并抵达更高的高
100 years ago, the liquid fuel rocket technology developed by American scientist Robert H. Goddard (1882.10.5-1945.8.10) paved the way for mankind to land on the moon, thus opening the era of space flight . Goddard, the father of modern rocket propulsion, has won 214 patents (83 patents were granted before his death), two of which are very important, the first of which is a liquid-fuel rocket and the second is a multi-stage rocket. The former can send a certain mass of load into Earth’s orbit, the latter being separated step by step after launch to achieve a reduction in mass and reaching a higher height
