As with the veteran RS-25, the RL10 has been continually upgraded over the years, alongside evaluations into its replacement, such as the effort seen in 2011 when an upgraded turbopump underwent a Preliminary Design Review (PDR) as part of the Next Generation Engine (NGE) project for the US Air Force, of which ULA rockets provide a major role.

(Part rebalancing) Mass reduced from 4 to 2.5, thrust increased from 135 to 220. Initial release (with LV-909 title and description). In the early 2000s, NASA contracted with Pratt & Whitney Rocketdyne to develop It performs very poorly in atmospheric conditions but it excels at vacuum operation. ... That's what this study will figure out, is it worthwhile to build an RL10 replacement?

In 2012 NASA joined with the US Air Force (USAF) to study next-generation upper stage propulsion, formalizing the agencies' joint interests in a new upper stage engine to replace the Aerojet Rocketdyne RL10. Using the printed copper alloy, instead of the more complex assemblage of braised stainless steel tubes, allows for the introduction of desirable attributes into the design.
Centaur ably delivered Cygnus into the correct 230km orbit and into its correct RAAN (Right Ascension of the Ascending Node), which ultimately classed the mission as a success. The intended role of this engine is as a power plant for large-diameter, upper stages of rockets for landings, orbital insertions, and transfers. For Aerojet Rocketdyne, this was the 455th RL10 engine to fly in space. What are the odds that Jeff Bezos' Blue Origin will fly people aboard New Shepard this year?

Aerojet Rocketdyne’s RL10 family of engines has been a key component of more than 475 flights and has been the upper stage engine of choice on NASA’s missions to every planet in the Solar System. The RL10 – which is used in various forms with Atlas’ Centaur Upper Stage (RL10A-3) and Delta IV’s Upper Stage (RL10B-2)- has a history back to the Saturn I’s S-IV Stage. The RL10 was originally developed as a throttleable engine for the USAF Lunex lunar lander, finally putting this capability to use twenty years later in the DC-X VTOL vehicle. * Different versions of the engine use different propellant combinations. The RL10C-X will increase the use of additive manufacturing and introduce other advanced technologies to improve the quality, reliability, affordability and performance.

Northrop Grumman Innovation Systems selected the RL10 … [citation needed], As of 2016, Aerojet Rocketdyne was working toward incorporating additive manufacturing into the RL10 construction process. the Common Extensible Cryogenic Engine (CECE) demonstrator. “Our trade studies have concluded that about 95 percent of the components that make up an RL10 could ultimately be built using additive manufacturing technology,” Aerojet Rocketdyne’s Nicholas Mulé told SpaceNews. How might this impact the larger spaceflight industry? Using 3-D printing, Aerojet Rocketdyne plans to reduce the time to manufacture the chamber from several months down to less than 30 days. This involves using precisely-aimed lasers to melt a powdered copper alloy, which effectively “prints” the part according to a detailed, digitized blueprint. This, combined with the hydrogen fuel, leads to very high specific impulses (Isp) in the range of 373 to 470 s (3.66–4.61 km/s) in a vacuum. “That’s just very powerful in itself.”. While some terms of the agreement remain confidential, it includes a long-term commitment by ULA to use RL10 engines on the company’s current Centaur and next-generation Centaur upper stages for future ULA procurements, as well as a joint commitment to invest in next-generation engine development. DARMA has been testing its engine at a test facility run by Frontier Astronautics in Chugwater, Wyo. [14] In 2007, its operability (with some "chugging") was demonstrated at 11:1 throttle ratios. DARMA is marketing it for $3 million apiece, which company officials say is almost 13 times lower than the $38 million cost for an RL-10 rocket used in the second stages of United Launch Alliance’s Atlas V and Delta IV boosters. Modern versions produce up to 110 kN (24,729 lbf) of thrust per engine in vacuum. An RL10 is on display at the Museum of Life and Science in Durham, NC, This page was last edited on 12 October 2020, at 01:21.
