对可重复使用运载火箭全寿命周期费用的组成进行了分析,建立了可重复使用运载火箭全寿命周期费用模型。基于此分析模型,分析了完全可重复使用运载火箭和一子级可重复使用运载火箭单枚单次发射平均全寿命周期费用随运载火箭发射次数的变化关系。结果表明,随运载火箭枚数与发射次数的增加,可重复使用运载火箭单枚单次发射平均全寿命周期费用显著降低,且当发射次数达到某一定值时,运载火箭单枚单次发射平均全寿命周期费用要低于运载火箭的制造费用;在可重复使用运载火箭全寿命周期费用中,降低操作费用在降低全寿命周期费用中不可忽视。
The composition of the reusable launch vehicle life-cycle cost was analyzed and the life-cycle cost model of the reusable launch vehicle was established. Based on this analytical model, the relationship between the average life-cycle cost of a single single launch of a fully reusable launch vehicle and a single reusable launch vehicle as a function of launching times of the launch vehicle is analyzed. The results show that with the increase of the number of launch vehicles and the number of launches, the average life-cycle cost of a single launch of a reusable launch vehicle significantly decreases. When the number of launches reaches a certain value, the single launch average of the launch vehicle averages Life-cycle costs are lower than those of launch vehicles; reducing operational costs among reusable launch vehicle life-cycle costs can not be ignored in reducing life-cycle costs.
