近年来人们对运载火箭下面级动力装置的液体燃料改用烃类燃料产生了极大兴趣.美国NASA兰利研究中心对采用各种液体燃料(H_2+O_2或烃类+O_2)的单级或重复使用运载火箭第一级的特性作了理论分析.一次性使用动力装置的运载火箭示意图如图1所示.
In recent years, great interest has been made in replacing hydrocarbon fuels with liquid fuels in power plants below the launch vehicle.United States NASA Langley Research Center of the United States using a variety of liquid fuels (H 2 O 2 or hydrocarbons + O 2) of the single-stage or The theoretical analysis of the characteristics of the first stage of the launch vehicle is repeated.The schematic diagram of the launch vehicle of the disposable power unit is shown in Fig.1.
