Aerojet Rocketdyne Completes J-2X Testing June 26, 2014 Aerojet Rocketdyne Completes J-2X Testing SACRAMENTO, Calif., June 26, 2014 (GLOBE NEWSWIRE) -- Aerojet Rocketdyne, a GenCorp (NYSE:GY) company, recently completed its final J-2X test series at NASA's Marshall Space Flight Center. Over a period of three years, Aerojet Rocketdyne teams manufactured, assembled and tested four newly developed engine test articles that achieved an accumulated duration of nearly five hours firing time and demonstrated full power operation for twice its designed life service. Delivering 30 percent more thrust and five percent more performance than the J-2 Apollo-era engine, upon which it is based, the J-2X is the highest performing human-rated upper-stage engine to be developed in nearly 40 years. "With J-2X, we were able to drive down the time needed to take a new rocket engine to 100 percent power level in testing, from 651 days to just 29, by integrating modern design, analysis and test practices with decades of experience gained on multiple engine development programs," said Aerojet Rocketdyne President Warren M. Boley, Jr. "That kind of knowledge isn't retained anywhere else in the industry and it demonstrates that we know how to design an engine that will work the first time." The J-2X is a liquid-oxygen/liquid-hydrogen fueled engine that is designed to start at altitude and re-start in space as part of a second or third stage of a large, multi-stage launch vehicle. With its full nozzle extension installed, the J-2X measures more than 15 feet tall and 10 feet in diameter at its base and weighs approximately 5,400 pounds. With a vacuum thrust of 294,000 lbs., the engine is designed to help loft heavy payloads—such as habitats, landers and in-space modules—beyond low-Earth orbit. "We had to modernize the J-2 engine to increase its power level and performance, so we had a good challenge on our hands," said Aerojet Rocketdyne's J-2X Director and Program Manager, Walt Janowski. "No part of this engine went untouched. We looked closely at each part to make sure it met modern standards and human-rated requirements." The completed J-2X testing provides direct benefits to Aerojet Rocketdyne's RS-25 test program, including understanding performance of the test stands and implementing new methods to record and interpret engine performance data. The RS-25 engines also feature a modernized engine controller, successfully demonstrated on J-2X, for controlling start and shutdown valve sequencing and health monitoring control functions. The J-2X engine is one of several options being considered to power the upper stage of NASA's future 130-metric-ton Space Launch System (SLS). The only vehicle with the mass, volume and speed required for human missions beyond low-Earth orbit, SLS will launch crew and cargo to deep space destinations. Capable of accomplishing these missions in fewer launches than any current or planned vehicle, NASA's SLS and Orion spacecraft programs are gearing up for major accomplishments this year. Orion's first flight test on a United Launch Alliance Delta IV Heavy, scheduled for December 2014, will take a human-rated spacecraft farther into space than one has been in 40 years. The mission will travel 15 times farther than the International Space Station and perform two Earth orbits to validate key functions including high velocity re-entry and recovery. Test firings of the RS-25 engine and SLS booster will demonstrate the performance of the vehicle's main propulsion systems, and the opening of the SLS Vertical Assembly Center will support welding of the vehicle's fuel tank - all important steps in preparing for deep space human explorations missions. A propulsion provider for all NASA human spaceflight programs and the Evolved Expendable Launch Vehicles, Aerojet Rocketdyne has delivered reliable propulsion solutions for more than 70 years. No other company has the experience and proven track record required to build these critical national assets. "Aerojet Rocketdyne is a propulsion innovator," said Boley. "We are redefining what the standards are for engine performance and we're ready to meet the propulsion needs of our nation."

  • Materials for Liquid Propulsion Systems

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.

Kennedy Space Center, Florida, United States of America 32899 [email protected]; [email protected]; [email protected] Abstract. The crawler transporter (CT) is the world’s second largest known tracked vehicle, weighing 6 million pounds with a length of 131 feet and a width of 113 feet. The Kennedy Space Center (KSC) has two CTs that were designed and built for the Apollo program in the 1960’s, maintained and retrofitted for use in the Space Shuttle program. As a key element of the Space Shuttle ground systems, the crawler transports the entire 12-million-pound stack comprising the orbiter, the mobile launch platform (MLP), the external tank (ET), and the solid rocket boosters (SRB) from the Vehicle Assembly Building (VAB) to the launch pad. This rollout, constituting a 3.5 to 5.0 mile journey at a top speed of 0.9 miles-per-hour, requires over 8 hours to reach either Launch Complex 39A or B. This activity is only a prelude to the spectacle of sound and fury of the Space Shuttle launch to orbit in less than 10 minutes and traveling at orbital velocities of Mach 24. This paper summarizes preliminary results from the Crawler Transporter Sound Attenuation Study, encompassing test and engineering analysis of significant sound sources to measure and record full frequency spectrum and intensity of the various noise sources and to analyze the potential for noise mitigation.

  • NASA Begins Engine Test Project for Space Launch System Rocket 21 July 2014, by Rachel Kraft
    NASA begins engine test project for space launch system rocket 21 July 2014, by Rachel Kraft shuttle," said Steve Wofford, SLS Liquid Engines Element manager. "This testing will confirm the RS-25 will be successful at powering SLS." Early tests on the engine will collect data on the performance of its new advanced engine controller and other modifications. The controller regulates valves that direct the flow of propellant to the engine, which determines the amount of thrust generated during an engine test, known as a hotfire test. In flight, propellant flow and engine thrust determine the speed and trajectory of a spacecraft. The controller also regulates the engine startup sequence, which is especially important on an engine as sophisticated as the RS-25. Likewise, the controller determines the engine shutdown sequence, ensuring it will proceed properly under RS-25 rocket engine No. 0525 is positioned onto the A-1 both normal and emergency conditions. Test Stand at NASA’s Stennis Space Center in Mississippi in preparation for a series of developmental "Installation of RS-25 engine No. 0525 signals the tests.
