The RL10 is a liquid-fuel cryogenic rocket engine built in the United States by Aerojet Rocketdyne that burns cryogenic liquid hydrogen and liquid oxygen propellants. Modern versions produce up to 110 kN (24,729 lb f) of thrust per engine in vacuum. RL10 versions were produced for the Centaur upper stage of the Atlas V and the DCSS of the Delta IV.

Two RL10 engines power the upper stage of ULA’s new Vulcan Centaur rocket. RL10 engines also help power NASA’s Space Launch System (SLS) rocket, designed to carry astronauts to deep-space destinations aboard the Orion exploration spacecraft. A single RL10 powered the Interim Cryogenic Propulsion Stage on Artemis I, an uncrewed test flight ...

2024年12月31日 · RL10火箭发动机 是美国研制的第一种液氢燃料火箭发动机，其改进版现用于多种运载器， 土星一号 的第二级使用六台， 半人马座上面级 使用一至两台， 德尔塔-4运载火箭 上面级使用一台。 曾有提案将该发动机用于 农神 一号， 农神 一B号， 农神五号 和 航天飞机。 该发动机第一次地面试车是在1959年，成品的第一次飞行是在1963年11月27日。 [1] 在这次飞行中，两台RL10A-3驱动宇宙神火箭的半人马座上面级。 这次飞行是用来检验火箭结构完整性和性能 …

rl10c是一个历史悠久的火箭发动机系列，主要用于半人马座上面级发动机、火神运载火箭、eus上面级等，是rl10系列氢氧发动机的最新型号。 技术参数 版本

2023年9月27日 · A single RL10 engine will provide nearly 25,000 pounds of thrust and serve as the main propulsion for the ICPS that will fly atop the SLS rocket Block 1 in support of each of the first three Artemis missions.

RL-10液体火箭发动机是美国“土星1号”运载火箭的上面级发动机和通用上面级“半人马座上面级”的主发动机。由美国普惠公司（Pratt&Whitney）于1958年～1963年研制。

Four RL10 engines will support the more powerful Exploration Upper Stage that is being developed for future versions of SLS, beginning with Artemis IV. L3Harris is also working to qualify a modern version of the engine known as the RL10C-X that will include major components built using 3D printing technology.

2022年10月15日 · The RL10 is the highest performance upper stage rocket engine in the world. It has provided precisely controlled, reliable power for a wide variety of earth orbital and interplanetary missions. Originally designed as a 15K lb thrust engine for the Atlas Centaur high energy upper stage, the engine has been upgraded numerous times to meet the ...

WEST PALM BEACH, Fla., Nov. 21, 2024 — L3Harris Technologies (NYSE:LHX) has delivered the first RL10 engine that features a 3D-printed copper thrust chamber to United Launch Alliance (ULA). The latest iteration, called the RL10E-1, uses 3D printing to enable a 98% reduction in the number of parts that make up the thrust chamber.
