Blue Origin Completes Acceptance Testing of BE-3 Engine for New Shepard Suborbital Flight
KENT, Wash. – Blue Origin recently completed acceptance testing of its BE‑3 rocket engine, the first new hydrogen engine to be developed in the United States in more than a decade. The 110,000-lbf BE‑3 will power Blue Origin’s New Shepard suborbital system, and later, will be modified for upper stage applications.
“The BE‑3 has now been fired for more than 30,000 seconds over the course of 450 tests,” said Jeff Bezos, Blue Origin founder. “We test, learn, refine and then test again to push our engines. The Blue Origin team did an outstanding job exploring the corners of what the BE‑3 can do and soon we’ll put it to the ultimate test of flight.”
The BE‑3 can be continuously throttled between 110,000-lbf and 20,000-lbf thrust, a key capability for vertical takeoff and vertical landing vehicles. The testing profile included multiple mission duty cycles, deep throttling and off-nominal test points.
“Liquid hydrogen is challenging, deep throttling is challenging and reusability is challenging,” said Bezos. “This engine has all three. The rewards are highest performance, vertical landing even with a single-engine vehicle and low cost. And, as a future upper stage engine, hydrogen greatly increases payload capabilities.”
The BE‑3 engine was designed and fabricated at Blue Origin’s design, development and production facility in Kent, Wash. Full-engine testing was conducted at the company’s facilities in West Texas, while earlier combustion chamber testing was completed at NASA’s Stennis Space Center in Mississippi.
The BE‑3 is the third generation of Blue Origin-developed engines. The fourth-generation BE‑4 uses liquid oxygen and liquefied natural gas (LNG) to produce 550,000-lbf thrust at sea level. Under development since 2012, the BE‑4 provides the lowest cost and fastest production path to power the nation’s access to space. Selected by United Launch Alliance to serve as the primary propulsion provider for its Next Generation Launch System, Blue Origin is developing the BE‑4 as an integrated part of America’s newest launch vehicle.
Blue Origin, LLC (Blue Origin) is a private company developing vehicles and technologies to enable commercial human space transportation. The company has a long-term vision of greatly increasing the number of people that fly into space through low-cost, highly reliable commercial space transportation.
