Atlas V Cutaway Poster
ATLAS V Since 2002, Atlas V rockets have delivered vital national security, science and exploration, and commercial missions for customers across the globe including the U.S. Air Force, the National Reconnaissance Oice and NASA. 225 ft The spacecraft is encapsulated in either a 5-m (17.8-ft) or a 4-m (13.8-ft) diameter payload fairing (PLF). The 4-m-diameter PLF is a bisector (two-piece shell) fairing consisting of aluminum skin/stringer construction with vertical split-line longerons. The Atlas V 400 series oers three payload fairing options: the large (LPF, shown at left), the extended (EPF) and the extra extended (XPF). The 5-m PLF is a sandwich composite structure made with a vented aluminum-honeycomb core and graphite-epoxy face sheets. The bisector (two-piece shell) PLF encapsulates both the Centaur upper stage and the spacecraft, which separates using a debris-free pyrotechnic actuating 200 ft system. Payload clearance and vehicle structural stability are enhanced by the all-aluminum forward load reactor (FLR), which centers the PLF around the Centaur upper stage and shares payload shear loading. The Atlas V 500 series oers 1 three payload fairing options: the short (shown at left), medium 18 and long. 1 1 The Centaur upper stage is 3.1 m (10 ft) in diameter and 12.7 m (41.6 ft) long. Its propellant tanks are constructed of pressure-stabilized, corrosion-resistant stainless steel. Centaur is a liquid hydrogen/liquid oxygen-fueled vehicle. It uses a single RL10 engine producing 99.2 kN (22,300 lbf) of thrust. -

Launcherone Success Opens New Space Access Gateway Guy Norris January 22, 2021
1/22/21 7:05 1/6 LauncherOne Success Opens New Space Access Gateway Guy Norris January 22, 2021 With San Nicolas Island far below, LauncherOne headed for polar orbit. Credit: Virgin Orbit Virgin Orbit had barely tweeted news of the successful Jan. 17 space debut of its LauncherOne vehicle on social media when new launch contracts began arriving in the company’s email inbox. A testament to the pent-up market demand for small-satellite launch capability, the speedy reaction to the long-awaited demonstration of the new space-access vehicle paves the way for multiple follow-on Virgin Orbit missions by year-end and a potential doubling of the rate in 2022. First successful privately developed air-launched, liquid-fueled rocket Payloads deployed for NASA’s Venture Class Launch Services program The glitch-free !ight of LauncherOne on its second demonstration test was a critical and much-welcomed milestone for the Long Beach, California-based company. Coming almost nine years a"er the air-launch concept was #rst unveiled by Virgin founder Richard Branson, and six years a"er the start of full-scale development, the !ight followed last May’s #rst demonstration mission, which ended abruptly when the rocket motor shut o$ a"er just 4 sec. 1/22/21 7:05 2/6 A"er an exhaustive analysis and modi#cations to beef up the oxidizer feed line at the heart of the #rst !ight failure, the path to the Launch Demo 2 test was then delayed until January 2021 by the COVID-19 pandemic. With the LauncherOne system now proven, design changes veri#ed and the #rst 10 small satellites placed in orbit, Virgin Orbit is already focusing on the next steps to ramp up its production and launch-cadence capabilities. -
Investigations of Liquid Steel Viscosity and Its Impact As the Initial Parameter on Modeling of the Steel Flow Through the Tundish

Mickiewicza 30, 30-059 Kraków, Poland 2 Department of Metallurgy and Metal Technology, Faculty of Production Engineering and Materials Technology, Cz˛estochowaUniversity of Technology, Al. Armii Krajowej 19, 42-201 Cz˛estochowa,Poland; [email protected] * Correspondence: [email protected] Received: 14 September 2020; Accepted: 5 November 2020; Published: 7 November 2020 Abstract: The paper presents research carried out to experimentally determine the dynamic viscosity of selected iron solutions. A high temperature rheometer with an air bearing was used for the tests, and ANSYS Fluent commercial software was used for numerical simulations. The experimental results obtained are, on average, lower by half than the values of the dynamic viscosity coefficient of liquid steel adopted during fluid flow modeling. Numerical simulations were carried out, taking into account the viscosity standard adopted for most numerical calculations and the average value of the obtained experimental dynamic viscosity of the analyzed iron solutions. Both qualitative and quantitative analysis showed differences in the flow structure of liquid steel in the tundish, in particular in the predicted values and the velocity profile distribution. However, these differences are not significant. In addition, the work analyzed two different rheological models—including one of our own—to describe the dynamic viscosity of liquid steel, so that in the future, the experimental stage could be replaced by calculating the value of the dynamic viscosity coefficient of liquid steel using one equation. -

Liquid Oxygen
Safetygram 6 Liquid oxygen Oxygen is the second largest component of the atmosphere, comprising 20.8% by volume. Liquid oxygen is pale blue and extremely cold. Although nonflammable, oxygen is a strong oxidizer. Oxygen is necessary to support life. Oxygen will react with nearly all organic materials and metals, usually forming an oxide. Materials that burn in air will burn more vigorously in oxygen. Equipment used in oxygen service must meet stringent cleaning requirements, and systems must be constructed of materials that have high ignition temperatures and that are nonreactive with oxygen under the service conditions. Vessels should be manufactured to American Society of Mechanical Engineers (ASME) codes and designed to withstand the process temperatures and pressures. Liquid oxygen is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid oxygen has a boiling point of –297°F (–183°C). Because the temperature difference between the product and the surrounding environment is substantial—even in the winter—keeping liquid oxygen insulated from the surrounding heat is essential. The product also requires special equipment for handling and storage. Oxygen is often stored as a liquid, although it is used primarily as a gas. Liquid storage is less bulky and less costly than the equivalent capacity of high-pressure gaseous storage. A typical storage system consists of a cryogenic storage tank, one or more vaporizers and a pressure control system. The cryogenic tank is constructed, in principle, like a vacuum bottle. There is an inner vessel surrounded by an outer vessel. Between the vessels is an annular space that contains an insulating medium from which all the air has been removed. -
