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. -

IAC-17- D2.4.3 Evaluation of Future Ariane Reusable VTOL Booster stages Etienne Dumonta*, Sven Stapperta, Tobias Eckerb, Jascha Wilkena, Sebastian Karlb, Sven Krummena, Martin Sippela a Department of Space Launcher Systems Analysis (SART), Institute of Space Systems, German Aerospace Center (DLR), Robert Hooke Straße 7, 28359 Bremen, Germany b Department of Spacecraft, Institute of Aerodynamics and Flow Technology, German Aerospace Center (DLR), Bunsenstraße 10, 37073 Gottingen, Germany *[email protected] Abstract Reusability is anticipated to strongly impact the launch service market if sufficient reliability and low refurbishment costs can be achieved. 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. -
Sailing Trans-Atlantic on the USCG Barque Eagle
PassageRite of Sailing Trans-Atlantic On The USCG Barque Eagle odern life is complicated. I needed a car, a bus, a train and a taxi to get to my square-rigger. When no cabs could be had, a young police officer offered me a lift. Musing on my last conveyance in such a vehicle, I thought, My, how a touch of gray can change your circumstances. It was May 6, and I had come to New London, Connecticut, to join the Coast Guard training barque Eagle to sail her to Dublin, Ireland. A snotty, wet Measterly met me at the pier, speaking more of March than May. The spires of New Lon- don and the I-95 bridge jutted from the murk, and a portion of a nuclear submarine was discernible across the Thames River at General Dynamics Electric Boat. It was a day for sitting beside a wood stove, not for going to sea, but here I was, and somehow it seemed altogether fitting for going aboard a sailing ship. The next morning was organized chaos. Cadets lugged sea bags aboard. Human chains passed stores across the gangway and down into the deepest recesses of the ship. Station bills were posted and duties disseminated. I met my shipmates in passing and in passageways. Boatswain Aaron Stapleton instructed me in the use of a climbing harness and then escorted me — and the mayor of New London — up the foremast. By completing this evolution, I was qualified in the future to work aloft. Once stowed for sea, all hands mustered amidships. -

Trade Studies Towards an Australian Indigenous Space Launch System
TRADE STUDIES TOWARDS AN AUSTRALIAN INDIGENOUS SPACE LAUNCH SYSTEM A thesis submitted for the degree of Master of Engineering by Gordon P. Briggs B.Sc. (Hons), M.Sc. (Astron) School of Engineering and Information Technology, University College, University of New South Wales, Australian Defence Force Academy January 2010 Abstract During the project Apollo moon landings of the mid 1970s the United States of America was the pre-eminent space faring nation followed closely by only the USSR. Since that time many other nations have realised the potential of spaceflight not only for immediate financial gain in areas such as communications and earth observation but also in the strategic areas of scientific discovery, industrial development and national prestige. Australia on the other hand has resolutely refused to participate by instituting its own space program. Successive Australian governments have preferred to obtain any required space hardware or services by purchasing off-the-shelf from foreign suppliers. This policy or attitude is a matter of frustration to those sections of the Australian technical community who believe that the nation should be participating in space technology. In particular the provision of an indigenous launch vehicle that would guarantee the nation independent access to the space frontier. It would therefore appear that any launch vehicle development in Australia will be left to non- government organisations to at least define the requirements for such a vehicle and to initiate development of long-lead items for such a project. It is therefore the aim of this thesis to attempt to define some of the requirements for a nascent Australian indigenous launch vehicle system. -

Sailing Course Materials Overview
SAILING COURSE MATERIALS OVERVIEW INTRODUCTION The NCSC has an unusual ownership arrangement -- almost unique in the USA. You sail a boat jointly owned by all members of the club. The club thus has an interest in how you sail. We don't want you to crack up our boats. The club is also concerned about your safety. We have a good reputation as competent, safe sailors. We don't want you to spoil that record. Before we started this training course we had many incidents. Some examples: Ran aground in New Jersey. Stuck in the mud. Another grounding; broke the tiller. Two boats collided under the bridge. One demasted. Boats often stalled in foul current, and had to be towed in. Since we started the course the number of incidents has been significantly reduced. SAILING COURSE ARRANGEMENT This is only an elementary course in sailing. There is much to learn. We give you enough so that you can sail safely near New Castle. Sailing instruction is also provided during the sailing season on Saturdays and Sundays without appointment and in the week by appointment. This instruction is done by skippers who have agreed to be available at these times to instruct any unkeyed member who desires instruction. CHECK-OUT PROCEDURE When you "check-out" we give you a key to the sail house, and you are then free to sail at any time. No reservation is needed. But you must know how to sail before you get that key. We start with a written examination, open book, that you take at home. -
Economic Benefits of Reusable Launch Vehicles for Space Debris Removal
68th International Astronautical Congress (IAC), Adelaide, Australia, 25-29 September 2017. Copyright ©2017 by the International Astronautical Federation (IAF). All rights reserved. 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 -
The Way of the Sea
1 The Way of the Sea Cheney Duvall stared up at the great clouds of soaring sail, though her eyes watered from the sun and salt sting. The Brynn Annalea had found a tail of the northeast trade winds, strong and hot, to wend her fast down Baja and push her easily over the Tropic of Cancer. Her sharp prow knifed the water, the jib with the lucky shark’s fin mounted on it splashing in the wave crests. She was a beautiful thing, fast, sharp-hulled, streamlined, proud. And dangerous. Cheney shouted up at Shiloh, and he was shouting back down at her. Neither of them could possibly hear the other, but both of them kept on. “You idiot! Come down from there this instant! You are going to fall and die!” Cheney shrieked. He made an impatient gesture—Get below, you dumb girl!— which made Cheney’s heart almost stop, for he had let go with one arm to make jabbing “get below” motions to her. Twelve seamen were perched along the bucking, straining yard, feet kicked back against the footrope, bellies pressed against the yard, hands gathering up the heavy canvas. Cheney watched, horrified, as they struggled to roll the great main royal sail around the yard. Finally it was wound as neatly as thread on a spool, and the sailors, with strong and agile movements, passed lengths of rope around sail and yard and made it fast with hitches. One by one they started edging back along the yard, making for the weather shrouds to scamper down. -

Colligo Marine® Lashing Tie Off Instructions
Colligo Marine® Lashing Tie off instructions This image shows a nicely finished off lashing using our CSS71 Line Terminator and CSS61 Chainplate Distributor using 5 mm or 3/16” Dyneema line. You can see the critical hourglass shape that gets tighter as the shroud tension gets tighter. It is very secure but is also allows for easy unlashing. Without the hourglass shape you would need to place the knot at the bottom of the lashing which makes it very painful to lash and unlash. There is a series of individual half hitches that form the attractive spiral configuration of the lashing. This also creates redundant security ensuring that your lashing will not shake out. Tensioning Prior to lashing off please tension the shroud or stay to the desired tension. Tensioning can be achieved in several ways: 1. The best method is to take your boat sailing and adjust the leeward shroud, letting the wind blow the rig to leeward and do the work for you. Tack back and forth in low to moderate winds and keep adjusting the leeward shrouds. Always keep the mast straight and in column. In the end, you want your leeward shrouds to just come loose at your wind reef point, usually about 15-20 knots of wind speed. 2. You can also bring a halyard down and tie it off to your lashing line and use a winch for tensioning. This method will probably mean that you would need to help the lashing line thru all the holes in the line terminators and distributors while at the same time adding tension with the winch. -
