为了准确地得到推进剂混合物，专利方案里展示了一个利用3 - D立体平版印刷术打印出燃料的混合动力火箭发动机。
To achieve the right mixture of propellant, the patent presents a hybrid rocket motor that would use 3-d stereolithography to essentially print the fuel.
然而我的理解是，“混合动力”火箭引擎同时使用固体燃料和液态或气态推进剂。
However, from what I gather, "hybrid" rocket engines use both solid and liquid or gas propellants.
鉴于化学燃料火箭浪费太多的推进剂难以实现飞船速度的静变化，电力推进器仅仅使用一小点推进剂就可以做同样的任务。
Whereas chemical rockets waste too much propellant to reach a net change in spacecraft velocity, electric thrusters can do exactly the same mission using just a small fraction of the propellant.
