KBR 2020 Proxy Statement
TO OUR FOR MAKING ANYTHING POSSIBLE NOTICE OF ANNUAL MEETING OF STOCKHOLDERS AND PROXY STATEMENT Dear KBR, Inc. Stockholders, As I write this letter to you for our Proxy Statement, the world is in the middle of a global health crisis. The COVID-19 outbreak is an unprecedented event, and although this is a time of significant uncertainty, we are taking actions to support our people, their families and our customers. With operations in China and South Korea we had an early warning of the potential impact of the virus, and this allowed us to plan ahead and stress test our operations for remote working. I am humbled by the amazing efforts of our people around the globe who have pulled together, shared ideas and implemented best practices to continue to provide world-class service for our customers while also protecting their well-being and the health and safety of their colleagues. It is this can-do, people-centric and forward-thinking culture that makes KBR a great company to be part of. It is thus a great honor to share with you this special Proxy Statement, which marks the 100-year anniversary of our company, and to dedicate it to the people who made it possible — our incredible employees. It is remarkable to think of all they have accomplished throughout KBR’s history, beginning in the earliest days, when they worked with teams of wagons and mules to pave rural roads, to today, when they are helping NASA return to the moon and discover life beyond Earth. Over the past 100 years, KBR has grown into an innovative and dynamic global company, and I am proud to be a part of this journey. -
Possibilities of Airframe Structures Cost Saving Through Reducing Number of Fasteners
Possibilities of airframe structures cost saving through reducing number of fasteners RŮŽEK Roman1,a, DOUBRAVA Radek1,b, KRUSE-STRACK Thomas2,c and KOERWIEN Thomas3,d 1Czech Aerospace Research Centre, Strength of Structure Department; Beranových 130, 199 05 Praha - Letňany, Czech Republic 2 Airbus Operations GmbH, Airframe Research & Technology, Kreetslag 10 21129 Hamburg Germany 3 Airbus Defence and Space GmbH, Materials & Processes, Rechliner Str., 85077 Manching, Germany [email protected], [email protected], [email protected], d [email protected] Keywords: Key, Word, Paper, Best conference, Contribution template (maximum of 5) Abstract. Reduction of numbers of mechanical fasteners together with bonding technology application can be one of the possibilities how to decrease costs of the structure. In the paper, results based on fatigue testing of novel design approaches for damage tolerant high load transfer (HLT) joints, as e.g. panel joints, are discussed for carbon fibre reinforced plastics (CFRP) adherents. Fatigue experimental results and numerical simulations of Wide Single Lap Shear (WSLS) specimen are presented for different configurations to proof the crack stopping behaviour of "state of the art" fasteners as reference crack arrestor concept. Introduction One of the main aims of designers is application of cost-effective strategies. The composite structures can lower costs of an airframe significantly, but there are some obstacles to adopt of advanced technologies like adhesive bonding or welding and prevent to use full strength capabilities of these technologies to real structures. Nowadays, there is no fully certified bonded technology applicable to full-scale airframe structure which comply airworthiness regulations from viewpoint of damage tolerance criteria. -

Stearns DATE SUBMITTED: August 2013 COMMITTEE CHAIR: Dr. Kira Abercromby, Assistant Professor Cal Poly Aerospace Engineering Department COMMITTEE MEMBER: Dr. Jordi Puig-Suari, Professor Cal Poly Aerospace Engineering Department COMMITTEE MEMBER: Dr. Kim Shollenberger, Professor Cal Poly Mechanical Engineering Department COMMITTEE MEMBER: Chris Biddy, Vice President of Engineering Stellar Exploration, Inc. iii ABSTRACT Thermal Analysis of a Monopropellant Micropropulsion System for a CubeSat Erin C. Stearns Propulsive capabilities on a CubeSat are the next step in advancement in the Aerospace Industry. This is no longer a quest that is being sought by just university programs, but a challenge that is being taken on by all of the industry due to the low-cost missions that can be accomplished. At this time, all of the proposed micro-thruster systems still require some form of development or testing before being flight- ready. Stellar Exploration, Inc. is developing a monopropellant micropropulsion system designed specifically for CubeSat application. The addition of a thruster to a CubeSat would expand the possibilities of what CubeSat missions are capable of achieving. The development of these miniature systems comes with many challenges. One of the largest challenges that a hot thruster faces is the ability to complete burns for the specified mission without transferring excessive heat into the propulsion tank. -

Now set yourself down in front of the typewriter — and write the damned thing!" In Re John D. Clark by Isaac Asimov I first met John in 1942 when I came to Philadelphia to live. Oh, I had known of him before. Back in 1937, he had published a pair of science fiction shorts, "Minus Planet" and "Space Blister," which had hit me right between the eyes. The first one, in particular, was the earliest science fiction story I know of which dealt with "anti-matter" in realistic fashion. Apparently, John was satisfied with that pair and didn't write any more s.f., kindly leaving room for lesser lights like myself. -
Fatigue Behavior and Damage Tolerant Design of Bonded Joints for Aerospace Application on Fiber Metal Laminates and Composites
29th ICAF Symposium – Nagoya, 7–9 June 2017 Fatigue behavior and damage tolerant design of bonded joints for aerospace application on Fiber Metal Laminates and composites Kruse, Thomas 1, Thomas Körwien², Roman Ruzek³, Robert Hangx1, Calvin Rans1 1 Technical University of Delft, Netherlands 2Airbus Defence and Space, Germany ³VZLU, Czech Republic Abstract: Today, the application of adhesive bonding technology for primary aerospace structures is limited due to the certification regulations. State of the art is the widely used “chicken rivet” as crack arrestor which is limiting the benefits of bonding technology, particularly in composite bonded joints. In this paper results from fatigue testing of novel design approaches for damage tolerant high load transfer (HLT) joints as e.g. Panel Joints or large bonded repairs will be discussed for CFRP and for Fiber Matel Laminates´(FML) adherents. Results from fatigue testing with Wide Single Lapshear (WSLS) specimen will be presented for different configurations to proof the crack stopping behavior of sate of the art fasteners as reference crack arrestor concept. STATE OF THE ART BONDING TECHNOLOGY With the entry into service of the A350XWB a consequent evolution of the usage of CFRP for primary structures within Airbus Group has reached the next milestone. After a long and excellent experience with CFRP in civil and military applications, first applied on secondary structures and since 1983 for the vertical stabilizer as first major primary structural component for civil aircrafts, Airbus Group has now reached the next step in the transition from a metallic to a composite aircraft with the first CFRP fuselage of an Airbus aircraft on A350 XWB. -
Delta Qualification Test of Aerojet Hydrazine
45th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit AIAA 2009-5481 2 - 5 August 2009, Denver, Colorado Delta-Qualification Test of Aerojet 6 and 9 lbf MR-106 Monopropellant Hydrazine Thrusters for Use on the Atlas Centaur Upper Stage During the Lunar Reconnaissance Orbiter (LRO) and Lunar Crater Observation and Sensing Satellite (LCROSS) Missions Jeffrey P. Honse1 Aerojet-General Corporation, Redmond, WA, 98052 Carl T. Bangasser2 United Launch Alliance, Littleton, CO, 80127 Michael J. Wilson3 Aerojet-General Corporation, Redmond, WA, 98052 This paper discusses a Delta-Qualification test of Aerojet’s 6 and 9 lbf monopropellant hydrazine MR-106 thrusters for use on the Atlas Centaur upper stage while operating in an atypical mode and for an extended period of time. This qualification testing was performed in support of the Lunar Reconnaissance Orbiter (LRO) and Lunar Crater Observation and Sensing Satellite (LCROSS) missions. The primary objective of the LCROSS mission is to determine the presence or absence of water ice in a permanently shadowed crater near a lunar polar region. The accomplishment of this objective requires that the Atlas V rocket’s Centaur upper stage perform a LCROSS orbit insertion as well as a fly-by of the moon before the Centaur upper stage crashes into a lunar crater to create a debris plume. The LCROSS satellite will pass through the debris to collect and relay plume constituent data back to Earth. Prior to the LCROSS separation from the Centaur upper stage, the Centaur pneumatic pressurization system will transition from regulated to blow-down mode, which requires that the thrusters operate at a lower propellant feed pressure than had previously been qualified.
