Progress on our #OmegaRocket! This C600 rocket motor case was recently delivered to our casting pits in Promontory, Utah where we will fill with inert propellant this week. This pathfinder motor will be one of three for the rocket. #NorthropGrumman

OmegA Update! We have successfully completed casting, or filling with propellant, the first live motor segment for our #OmegaRocket. The segment is specifically designed to support the needs of our new intermediate- to heavy-lift rocket. #NorthropGrumman http://bit.ly/2QaO4ej

Thursday we will be firing one of our newly-developed Graphite Epoxy Motors (GEM) 63. These motors will be used to support intermediate- and large-class launch vehicles including @ulalaunch's #AtlasV. Stay tuned for more info! #NorthropGrumman

We're ready! Here's a view of the test site where our #GEM63 motor will be firing off in just one hour. The motor has been in a test bay to keep it cooled to ~40 degrees F, which represents the lower parameters of what we are trying to qualify with this test.

Northrop Grumman to Test First GEM 63 Motor

Northrop Grumman

Опубликовано: 18 сент. 2018 г.

On Thursday, September 20, Northrop Grumman will conduct its first ground test of a 63-inch diameter Graphite Epoxy Motor (GEM 63) in Promontory, Utah. Utilizing advanced technologies, the company developed this new rocket motor for use on the United Launch Alliance (ULA) Atlas V launch vehicle.

Northrop Grumman Successfully Completes First Qualification Test of New Rocket Motor for United Launch Alliance Atlas V

Graphite epoxy motors will help launch rocket beginning in 2019

September 20, 2018

Dulles, Va. – Sept. 20, 2018 – Northrop Grumman Corporation (NYSE: NOC) conducted its first ground test of a 63-inch diameter Graphite Epoxy Motor (GEM 63) today in Promontory, Utah. Utilizing advanced technologies, the company developed this new rocket motor for use on the United Launch Alliance (ULA) Atlas V launch vehicle.

On Sept. 20, 2018, in Promontory, Utah, Northrop Grumman conducted the first ground test of its newly-developed GEM 63 rocket motor that will fly on United Launch Alliance's Atlas V launch vehicle.

Northrop Grumman began developing the motor just three years ago, reaching this static test milestone in rapid time for such a complex drop-in solution to an existing launch vehicle. The team developed the innovative design that tailors motor performance to meet ULA design objectives under a cooperative development program.

"Northrop Grumman has been supplying solid propulsion motors for a variety of launch vehicles since 1964," said Scott Lehr, president, flight systems, Northrop Grumman. "As ULA's largest legacy supplier of solid propulsion, we're pleased that our most recent product has reached this important milestone. The successful completion of this test enables full production to begin."

The GEM 63 motor will be used as a direct replacement of the previous strap-on boosters on ULA's Atlas V rocket beginning in July 2019 with the Space Test Program (STP)-3 mission that will use five boosters. Additional missions will follow, each of which may include up to five solid rocket motors.

The relationship with ULA began in 1964 when Thiokol (a Northrop Grumman predecessor company), in Huntsville, Alabama, provided three CASTOR® I strap-on rocket motors for the Delta D rocket. Several years later, CASTOR IIs flew on the Delta E rocket, and subsequently CASTOR IVs helped launch higher-performing Delta rockets. Also, CASTOR IVAs flew on the Atlas IIAS vehicle from 1993 to 2004, when 120 solid rocket boosters flew on 30 successful Atlas IIAS launches. Prior to the current Delta IV heavy launch vehicle, Northrop Grumman provided the large three-segmented Solid Rocket Motor Upgrade (SRMU) strap-on booster for the Titan IVB rocket. Thirty four SRMUs successfully flew on Titan IV from 1997 to 2005.

Northrop Grumman, then Hercules, began developing the GEM family of strap-on motors in the late 1980s with the GEM 40, 1,003 of which have subsequently flown on 132 successful Delta II launches. The company also developed the GEM 46, 54 of which flew on six successful Delta II-Heavy launches. Northrop Grumman later developed the GEM 60, and to date 62 of these motors have flown on 25 successful Delta IV launches. The company's family of GEM 63 rocket motors builds on this extensive flight history.

Northrop Grumman is also developing a GEM 63XL motor using internal funding for use on ULA's Vulcan Centaur rocket, which will fly with up to six GEM 63XLs per flight. The first GEM 63XL case, which is the longest non-segmented, monolithic case ever manufactured, has already been wound at a new facility in Clearfield, Utah.

Both versions of the GEM 63 family use common materials and processes to maintain a high-reliability, low-cost product. The next GEM 63 motor test, scheduled for November, will satisfy additional requirements for certification by the U.S. Air Force.

Опубликовано: 20 сент. 2018 г.

Our GEM 63 rocket motor fired for approximately 105 seconds September 20 as we completed its first ground test at our Promontory, Utah, test site. The booster, developed for use on the United Launch Alliance Atlas V rocket, will be used as a direct replacement of the previous strap-on boosters beginning in July 2019.

In honor of @MfgDay this Fri, we're celebrating our employees across the country! Here, technicians move a C600 inert aft segment case for #NorthropGrumman's 1st stage motor for the #OmegaRocket into an autoclave to cure the rubber insulation on the inside of the case.
