Aerojet Rocketdyne和SMC投资发动机技术
中国玻璃纤维复合材料信息网 (cnbxfc.net) 发布日期: 2018-07-06  阅读: 718  字体:  双击鼠标滚屏
 Aerojet Rocketdyne宣布扩大其与空军太空与导弹系统中心(SMC)现有的先进发动机开发协议,以开发上级RL10C-X发动机,并通过生产第一台发动机继续AR1增压发动机开发计划。

RL10C-X代表未来的上级火箭发动机RL10,它已经积累了超过50年的成熟飞行经验。使用先进的3D打印技术与其他现代制造技术相结合,RL10C-X的生产成本将大大降低,同时不会影响当前性能和可靠性或影响运载火箭接口。
 
Aerojet Rocketdyne已经完成了几次使用3D打印构建的组件的热火演示,包括用于RL10C-X的新推力室组件。目前由许多部件构建的发动机的主要部件将需要大量的触摸劳动力来制造和组装,这些部件将被整合到几个3D打印部件中,从而减少交付时间和成本。通过RL10C-X,Aerojet Rocketdyne将能够以更低的成本为客户提供高可靠性,高性能的上级发动机。
 
Aerojet Rocketdyne首席执行官兼总裁Eileen Drake说:“Aerojet Rocketdyne在为该国大部分卓越的运载火箭制造火箭发动机方面拥有丰富的经验,我们将继续使用RL10C-X发动机。” “我们也很高兴能继续开发AR1发动机;这是一个美好的未来。“
 
AR1使用液氧(LOX)/煤油(RP-1)提供超过500,000磅的推力,适用于为当前和未来的中型至重型运载火箭的核心级提供动力。它采用了业界领先的制造技术,包括3D打印,以提高可负担性。
 
“我们目前正在制造我们的第一台完整的AR1发动机,该发动机将在2019年进行热火试验,”德雷克补充道。 “AR1是广泛应用的理想引擎;它为中型到重型的运载火箭提供了合适的推进剂组合,推力水平,尺寸和性能。与RL10C-X上级发动机相结合,AR1将进一步降低发动推进成本,并具有经过飞行验证的公司的计划信心和任务保证。我坚持认为,Aerojet Rocketdyne通过结合先进技术和成熟的开发和生产流程,为运载火箭领域提供最佳的增压和上级推进解决方案。“
 
Aerojet Rocketdyne和空军于2018年6月22日签署了对其现有火箭推进系统其他交易机构协议的修改,以资助此次合作。

Aerojet Rocketdyne announces an expansion of its existing advanced engine development agreement with the Air Force’s Space and Missile Systems Center (SMC) to develop the upper-stage RL10C-X engine and continue the AR1 booster engine development program through production of the first engine.

 

 

Aerojet Rocketdyne and SMC investing in engine technology
The RL10C-X represents the future upper-stage rocket engine, the RL10, which has accumulated more than 50 years of proven flight experience. Using advanced 3D printing technology paired with other modern manufacturing techniques, production costs for the RL10C-X will be greatly reduced without compromising current performance and reliability or impacting the launch vehicle interfaces.

Aerojet Rocketdyne has completed several hot-fire demonstrations of components built using 3D printing, including a new thrust chamber assembly for the RL10C-X. Major components of the engine that are currently built from many parts that require significant touch labor to fabricate and assemble will be consolidated into just a few 3D printed parts, reducing lead-times and costs. With RL10C-X, Aerojet Rocketdyne will be able to continue to offer a highly-reliable, high-performance upper-stage engine at reduced costs to its customers.

“Aerojet Rocketdyne has extensive experience building rocket engines for most of the nation’s preeminent launch vehicles and we will continue that legacy with the RL10C-X engine,” said Eileen Drake, CEO and president of Aerojet Rocketdyne. “We’re also excited to continue development of the AR1 engine; this is an American engine with a bright future.”

The AR1 uses liquid-oxygen (LOX)/kerosene (RP-1) to provide over 500,000 pounds of thrust and is suited to power the core stage of current and future medium- to heavy-lift launch vehicles. It incorporates industry-leading manufacturing technology, including 3-D printing to enhance affordability.

“We are currently manufacturing our first complete AR1 engine that will be ready for hot-fire testing in 2019,” added Drake. “AR1 is an ideal engine for a wide number of applications; it brings together the right propellant combination, thrust level, size and performance for launch vehicles in the medium to heavy class. In combination with the RL10C-X upper-stage engine, the AR1 will further drive down the cost of launch propulsion with the schedule confidence and mission assurance of a flight-proven company. I remain steadfast that Aerojet Rocketdyne offers the best boost and upper stage propulsion solutions across the launch vehicle spectrum by combining advanced technology and proven development and production processes.”

Aerojet Rocketdyne and the Air Force signed a modification to their existing Rocket Propulsion System Other Transactional Authority agreement on June 22, 2018 to fund this collaboration.
