  西安4月24日电(记者张一辰)北京时间4月24日17时17分,长征二号F遥二十运载火箭托举着载有陈冬、陈中瑞、王杰3名航天员的神舟二十号载人飞船,在酒泉卫星发射中心点火发射奔赴“天宫”。约10分钟后,飞船与火箭成功分离,进入预定轨道。

  此次发射神舟二十号载人飞船的长征二号F遥二十运载火箭,其芯一级、芯二级以及助推器所使用的发动机均由中国航天科技集团六院(下称:航天科技六院)研制。该院为长征二号F遥二十运载火箭与神舟二十号载人飞船研制交付了共58台主推进及姿轨控发动机,以及热控分系统和生命保障系统泵阀等关键设备,这些设备如同飞船的“心脏”与“动脉”,为飞船提供源源不断的动力,确保其在浩瀚宇宙中能够按照预定轨道飞行、完成各项复杂任务。

  据了解,为了确保“神二十”发射任务的圆满成功,航天科技六院积极进行技术创新,通过采用新型耐高温、高强度材料,提升发动机关键部件的使用寿命;通过先进的燃烧组织方式和控制技术,有效提高了发动机燃烧的稳定性,进一步提升了发动机的性能和可靠性。

  航天科技六院表示,随着中国载人航天工程向载人登月等目标迈进,该院将持续加大技术创新投入,不断提升液体火箭发动机技术水平,为中国航天事业的发展提供更加强劲、可靠的动力支持。(完) 你看起来很好亲小说全文免费阅读:搞笑瞬间引发热议,网友们纷纷分享的欢乐时刻!的相关文章 大妈为年轻10岁做媚眼后哗哗流泪的相关文章
