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.

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.

AEHF-6 Launch Marks 500Th Flight of Aerojet Rocketdyne's RL10 Engine
AEHF-6 Launch Marks 500th Flight of Aerojet Rocketdyne’s RL10 Engine March 27, 2020 CAPE CANAVERAL, Fla., March 26, 2020 (GLOBE NEWSWIRE) -- The successful March 26 launch of the U.S. Space Force’s sixth and final Advanced Extremely High Frequency (AEHF) military communications satellite aboard a United Launch Alliance (ULA) Atlas V rocket marked the 500th flight of Aerojet Rocketdyne’s RL10 upper-stage engine. The RL10, which powers the ULA Atlas V Centaur upper stage, is one of several Aerojet Rocketdyne propulsion products supporting the mission. Aerojet Rocketdyne propulsion can be found on both the rocket and the AEHF-6 satellite. Built by Lockheed Martin, the AEHF satellites provide secure, jam-proof communications, including nuclear command and control, to U.S. and allied forces. “This launch marks an important milestone for Aerojet Rocketdyne and for the country,” said Eileen Drake, Aerojet Rocketdyne’s CEO and president. “The RL10 has supported a majority of the nation’s most important national security and scientific missions, including all of the AEHF satellites which provide communication links that are critical to our warfighters.” The Atlas V in the 551 configuration is the most powerful vehicle in the Atlas V family, featuring five Aerojet Rocketdyne AJ-60A solid rocket strap-on motors, each generating 348,500 pounds of thrust. Designed specifically to provide extra lifting power to the Atlas V, the AJ-60A is the world’s largest monolithic solid rocket motor ever flown. The AEHF-6 satellite, meanwhile, is outfitted with three different types of Aerojet Rocketdyne thrusters for attitude control, orbital station keeping and maneuvering.

Materials for Liquid Propulsion Systems
CHAPTER 12 Materials for Liquid Propulsion Systems John A. Halchak Consultant, Los Angeles, California James L. Cannon NASA Marshall Space Flight Center, Huntsville, Alabama Corey Brown Aerojet-Rocketdyne, West Palm Beach, Florida 12.1 Introduction Earth to orbit launch vehicles are propelled by rocket engines and motors, both liquid and solid. This chapter will discuss liquid engines. The heart of a launch vehicle is its engine. The remainder of the vehicle (with the notable exceptions of the payload and guidance system) is an aero structure to support the propellant tanks which provide the fuel and oxidizer to feed the engine or engines. The basic principle behind a rocket engine is straightforward. The engine is a means to convert potential thermochemical energy of one or more propellants into exhaust jet kinetic energy. Fuel and oxidizer are burned in a combustion chamber where they create hot gases under high pressure. These hot gases are allowed to expand through a nozzle. The molecules of hot gas are first constricted by the throat of the nozzle (de-Laval nozzle) which forces them to accelerate; then as the nozzle flares outwards, they expand and further accelerate. It is the mass of the combustion gases times their velocity, reacting against the walls of the combustion chamber and nozzle, which produce thrust according to Newton’s third law: for every action there is an equal and opposite reaction. [1] Solid rocket motors are cheaper to manufacture and offer good values for their cost. Liquid propellant engines offer higher performance, that is, they deliver greater thrust per unit weight of propellant burned.
