  • ULA Atlas V Launch to Feature Full Complement of Aerojet Rocketdyne Solid Rocket Boosters
    April 13, 2018 ULA Atlas V Launch to Feature Full Complement of Aerojet Rocketdyne Solid Rocket Boosters SACRAMENTO, Calif., April 13, 2018 (GLOBE NEWSWIRE) -- The upcoming launch of the U.S. Air Force Space Command (AFSPC)-11 satellite aboard a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station, Florida, will benefit from just over 1.74 million pounds of added thrust from five AJ-60A solid rocket boosters supplied by Aerojet Rocketdyne. The mission marks the eighth flight of the Atlas V 551 configuration, the most powerful Atlas V variant that has flown to date. The Atlas V 551 configuration features a 5-meter payload fairing, five AJ-60As and a Centaur upper stage powered by a single Aerojet Rocket RL10C-1 engine. This configuration of the U.S. government workhorse launch vehicle is capable of delivering 8,900 kilograms of payload to geostationary transfer orbit (GTO), and also has been used to send scientific probes to explore Jupiter and Pluto. The Centaur upper stage also uses smaller Aerojet Rocketdyne thrusters for pitch, yaw and roll control, while both stages of the Atlas V employ pressurization vessels built by Aerojet Rocketdyne's ARDÉ subsidiary. "The Atlas V is able to perform a wide variety of missions for both government and commercial customers, and the AJ-60A is a major factor in that versatility," said Aerojet Rocketdyne CEO and President Eileen Drake. "Aerojet Rocketdyne developed the AJ-60A specifically for the Atlas V, delivering the first booster just 42 months after the contract award, which underscores our team's ability to design and deliver large solid rocket motors in support of our nation's strategic goals and efforts to explore our solar system." The flight of the 100th AJ-60A, the largest monolithically wound solid rocket booster ever flown, took place recently as part of a complement of four that helped an Atlas V 541 place the nation's newest weather satellite into GTO.

  • Space Launch System (Sls) Motors
    Propulsion Products Catalog SPACE LAUNCH SYSTEM (SLS) MOTORS For NASA’s Space Launch System (SLS), Northrop Grumman manufactures the five-segment SLS heavy- lift boosters, the booster separation motors (BSM), and the Launch Abort System’s (LAS) launch abort motor and attitude control motor. The SLS five-segment booster is the largest solid rocket motor ever built for flight. The SLS booster shares some design heritage with flight-proven four-segment space shuttle reusable solid rocket motors (RSRM), but generates 20 percent greater average thrust and 24 percent greater total impulse. While space shuttle RSRM production has ended, sustained booster production for SLS helps provide cost savings and access to reliable material sources. Designed to push the spent RSRMs safely away from the space shuttle, Northrop Grumman BSMs were rigorously qualified for human space flight and successfully used on the last fifteen space shuttle missions. These same motors are a critical part of NASA’s SLS. Four BSMs are installed in the forward frustum of each five-segment booster and four are installed in the aft skirt, for a total of 16 BSMs per launch. The launch abort motor is an integral part of NASA’s LAS. The LAS is designed to safely pull the Orion crew module away from the SLS launch vehicle in the event of an emergency on the launch pad or during ascent. Northrop Grumman is on contract to Lockheed Martin to build the abort motor and attitude control motor—Lockheed is the prime contractor for building the Orion Multi-Purpose Crew Vehicle designed for use on NASA’s SLS.

DLR is performing an extensive study on return methods for a reusable booster stage for a future launch vehicle. The present study focuses on the vertical take-off and vertical landing (VTOL) method. First, a restitution of a flight of Falcon 9 is presented in order to assess the accuracy of the tools used. Then, the preliminary designs of different variants of a future Ariane launch vehicle with a reusable VTOL booster stage are described. The proposed launch vehicle is capable of launching a seven ton satellite into a geostationary transfer orbit (GTO) from the European spaceport in Kourou. Different stagings and propellants (LOx/LH2, LOx/LCH4, LOx/LC3H8, subcooled LOx/LCH4) are considered, evaluated and compared. First sizing of a broad range of launcher versions are based on structural index derived from existing stages.

IAC-17-A6.8.5 Economic Benefits of Reusable Launch Vehicles for Space Debris Removal Matthew P. Richardsona*, Dominic W.F. Hardyb a Department of Aeronautics and Astronautics, University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo, Japan 113- 8656, [email protected] b Nova Systems, 53 Ellenborough Street, Ipswich, Queensland, Australia 4305, [email protected] * Corresponding Author Abstract An analysis of cost savings which could be realized on active debris removal missions through the use of reusable launch vehicles has been performed. Launch vehicle price estimates were established for three levels of reusable launch vehicle development, based on varying levels of technological development and market competition. An expendable launch vehicle price estimate was also established as a point of comparison. These price estimates were used to form two separate debris removal mission cost estimates, based on previously-proposed debris removal mission concepts. The results of this analysis indicate that reusable launch vehicles could reduce launch prices to levels between 19.6% and 92.8% cheaper than expendable launch vehicles, depending on the level of RLV maturity. It was also determined that a reusable launch vehicle could be used to realize total active debris removal mission cost savings of between 2.8% (for a partially reusable launch

  • Aerojet Marks 70 Years Serving the Warfighter and Powering Exploration
    March 19, 2012 Aerojet Marks 70 Years Serving the Warfighter and Powering Exploration SACRAMENTO, Calif., March 19, 2012 (GLOBE NEWSWIRE) -- Aerojet, a GenCorp (NYSE:GY) company, announced its 70th anniversary today, marking the March 19, 1942 founding of Aerojet Engineering Corporation by world-renowned aerodynamicist Dr. Theodore von Kármán and five California Institute of Technology colleagues. These rocket pioneers leveraged their ingenuity and shared passion for rocketry to create a company that today has powered some of the nation's most critical defense and exploration missions. Launching as a single-product company, Aerojet manufactured critical Jet Assisted Take Off (JATO) propulsion, which led to increased allied pilot safety by enabling heavily laden aircraft to take off from short runways and carrier decks. Following the allied forces' victory in WWII, Aerojet's production efforts turned to the development of solid rocket propellant motors for the Intercontinental Ballistic Missile (ICBM) Minuteman, as well as solid rocket motors for the two-stage submarine- launched ballistic missile, Polaris. Aerojet also began work on the Titan program. The company ultimately spent the next 50 years producing liquid rocket engines for the entire Titan launcher family: Titan I, Titan II, Titan III and Titan IV. Space Exploration and Defending Freedom With the launch of the space race in the 1960s, Aerojet's propulsion expertise powered the nation's early exploration accomplishments. In 1966, three of every four rockets launched from Cape Canaveral, Fla. were powered by Aerojet propulsion systems. Following the two-man missions of Gemini, Aerojet's Service Propulsion System placed Apollo astronauts in orbit around the moon and brought them home again.
