寻找宇宙的奥秘,探索广阔而神秘的外太空,发现外星生物是人类自古以来的梦想。而真正为人类迈向太空提供科学方法的是俄罗斯科学家齐奥尔科夫斯基。他指出,采用喷气发动机的多级火箭,是实现航空航天的唯一有效的方法。宇宙穿梭机、星际飞船、导弹等都是以火箭为动力,火箭的原理实质上就是动量守恒定律。火箭的内部装有燃料和氧化剂,它们经过输送泵进入燃料室,燃烧生成的炽热气体向后喷射,获得向后的动量,按动量守恒定律,火箭获得向前的动量。燃料持续燃
Looking for the mysteries of the universe, to explore vast and mysterious outer space, found that alien life is the dream of mankind since ancient times. The real scientific way for mankind to go to space is the Russian scientist Qi Autarchski. He pointed out that the use of multi-stage rockets jet engine is the only effective way to achieve aerospace. Space shuttle, spacecraft, missiles and other rockets are powered by rocket theory is essentially the law of conservation of momentum. The rocket’s interior is filled with fuel and oxidant, and they pass through the pump into the fuel chamber. The hot gas generated by the combustion is injected backwards for backward momentum. The rocket gains forward momentum, according to the law of conservation of momentum. Fuel continues to burn
