The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters developed in the late 1980s and used since 1990. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant. GEM is produced by Northrop Grumman Space Systems. [1]
The TR-107 was a developmental rocket engine designed in 2002 by Northrop Grumman for the NASA and DoD-funded Space Launch Initiative (SLI). Operating on LOX/RP-1, the engine was throttleable and had a thrust of 4,900 kN (1,100,000 lbf) at a chamber pressure of 17.7 megapascals (177 bar), making it one of the most powerful engines ever constructed.
Castor is a family of solid-fuel rocket stages and boosters built by Thiokol (now Northrop Grumman) and used on a variety of launch vehicles. [1] They were initially developed as the second-stage motor of the Scout rocket .
The Star 48 is the largest of a family of solid rocket motors used by many space propulsion and launch vehicle stages, almost exclusively as an upper stage.It was developed primarily by Thiokol Propulsion and after several mergers, is manufactured by Northrop Grumman’s Space Systems division.
The Federal Trade Commission (FTC) approved the acquisition with conditions on June 5, 2018, and on June 6, 2018, Orbital ATK was renamed Northrop Grumman Innovation Systems. [ 7 ] [ 8 ] With Northrop Grumman's reorganization of its divisions effective January 1, 2020, Northrop Grumman Innovation Systems was split, with most of the sector ...
The first motor is made by Northrop Grumman. This first stage incorporates a solid propellant motor, parts to ensure first-stage ignition, and a thrust vector control (TVC) system. The first-stage section, compared to the Trident C-4, is slightly larger, allowing increased range and a larger payload. In addition to a larger motor, the D-5 uses ...
The Minotaur VI is a five-stage launch vehicle proposed by Northrop Grumman that, as of 2024, has not flown. Minotaur VI is based on the Minotaur IV+, adding a second SR-118 first stage to increase performance. [5] A further enhanced variant, Minotaur VI+, is also proposed for beyond low Earth orbit missions using an added Star 37FM sixth stage ...
The Graphite-Epoxy Motor (GEM) is a solid rocket motor produced by ATK using epoxy composite casing. GEMs are used as boosters for the Delta II , Delta III , and Delta IV launch vehicles . The use of composite materials allows for booster casings several times lighter than the steel casings of the Castor 4 solid rocket motors they replaced. [ 31 ]
