摘要:
The invention relates to the field of rocket engines, and more particularly to a propulsion assembly (10) comprising a first tank (11) for a first liquid propellant, a second tank (12) for a second liquid propellant, a pressurizer device (60) configured to maintain a substantially higher pressure in the second tank (12) than in the first tank (11), and a single-shaft turbopump (30) comprising a turbine (33), a first pump (31), and a second pump (32). The turbine (33) is actuated by expansion of the first propellant after it has passed through a regenerative heat exchanger (44), and in turn it acts via the single rotary shaft (34) of the turbopump (30) to drive said first and second pumps (31, 32) respectively pumping said first and second propellants in order to feed a propulsion chamber (40).
摘要(中):
本发明涉及火箭发动机领域,更具体地涉及一种推进组件(10),其包括用于第一液体推进剂的第一罐(11),用于第二液体推进剂的第二罐(12),加压装置(60) )构造成在第二箱(12)中保持比在第一箱(11)中显着更高的压力,以及单轴涡轮泵(30),其包括涡轮机(33),第一泵(31)和第二泵 泵(32)。 第一推进剂在其通过再生热交换器(44)之后的膨胀致动涡轮(33),并且再次通过涡轮泵(30)的单个旋转轴(34)作用以驱动所述第一推进剂和 分别泵送所述第一和第二推进剂以便馈送推进室(40)的第二泵(31,32)。
