This book was released on 2018-08-20 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The requirement for long-term, reliable operation of aerospace mechanisms has, with a few exceptions, pushed the state of the art in tribology. Space mission life requirements in the early 1960s were generally 6 months to a year. The proposed U.S. space station schedule to be launched in the 1990s must be continuously usable for 10 to 20 years. Liquid lubrication systems are generally used for mission life requirements longer than a year. Although most spacecraft or satellites have reached their required lifetimes without a lubrication-related failure, the application of liquid lubricants in the space environment presents unique challenges. The state of the art of liquid lubrication in space as well as the problems and their solutions are reviewed. Zaretsky, Erwin V. Glenn Research Center RTOP 505-63-1B...

Download or read book Evaluation of an In-Situ, Liquid Lubrication System for Space Mechanisms Using a Vacuum Spiral Orbit Tribometer written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2018-09-27 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many moving mechanical assemblies (MMAs) for space applications rely on a small, initial charge of lubricant for the entire mission lifetime, often in excess of five years. In many cases, the premature failure of a lubricated component can result in mission failure. If lubricant could be resupplied to the contact in-situ, the life of the MMA could be extended. A vacuum spiral orbit tribometer (SOT) was modified to accept a device to supply re-lubrication during testing. It was successfully demonstrated that a liquid lubricant (Pennzane (Registered Trademark)/Nye 2001A) could be evaporated into a contact during operation, lowering the friction coefficient and therefore extending the life of the system.

This book was released on 2018-10-28 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Future spacecraft must be designated to operate for very long time periods in space. For example, a target goal for the Space Station is 30 years of operation. Although the actual life may be significantly less than this optimistic goal, the life will certainly be a critical issue in design. The bearings on primary components such as the alpha and beta joints must obviously be designed and lubricated with the objective of optimum performance life. In addition to these joints, there will be numerous other tribological (rubbing or rolling) interfaced that will be required to function for the life of the spacecraft. A major key to adequate performance of tribological interface is proper lubrication. Lubricants can be divided into two basic classes: solid films and liquids. Both types have been used extensively in space applications. Both have advantages and disadvantages that must be carefully considered in their selection. The purpose here is to summarize selection criteria for liquid and solid lubricants applied to long-life spacecraft. Kannel, J. W. and Lowry, J. A. and Dufrane, K. F. Unspecified Center NAS8-36655...

This book was released on 2011-04-14 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Chemistry and Technology of Lubricants" describes the chemistry and technology of base oils, additives and applications of liquid lubricants. This Third Edition reflects how the chemistry and technology of lubricants has developed since the First Edition was published in 1992. The acceleration of performance development in the past 35 years has been as significant as in the previous century: Refinery processes have become more precise in defining the physical and chemical properties of higher quality mineral base oils. New and existing additives have improved performance through enhanced understanding of their action. Specification and testing of lubricants has become more focused and rigorous. "Chemistry and Technology of Lubricants" is directed principally at those working in the lubricants industry as well as individuals working within academia seeking a chemist's viewpoint of lubrication. It is also of value to engineers and technologists requiring a more fundamental understanding of the subject.

This book was released on 2019 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Lubricants are substances used for reducing friction wear tear and energy losses between two moving bodies. For space applications, normal lubricants cannot be used as they cannot survive the harsh and demanding conditions of space. Multiple Alkylated Cyclopentanes (MACs) have been utilized as space lubricants in recent times with tremendous results. NASA uses the MACs for their missions in space, in particular 1,3,4- tri-(2-octyldodecyl) cyclopentane sold by Nye Lubricants under the name of Pennzane[sup TM]. In this research, an effort has been made to identify appropriate potential models for simulating Pennzane molecules and to develop MD simulation codes to construct realistic model systems comprising Pennzane thin films sandwiched between two [alpha]- alumina surfaces. The results from the MD simulations show that, unlike symmetric molecules that can be induced by nanoscopic confinement to form layered configurations, the highly branched Pennzane possesses sufficient structural asymmetry and complexity to resist the layering tendency. Surface interactions are found to bend segments of the proximal branches into non-trans conformations that lie parallel to the surfaces. The resultant strong interactions appear to function as an anchor that promotes the branches in a crowded environment to stand more straight up. The realistic model system of an important liquid lubricant developed in this work can serve as a key to open many research directions and possibilities, including the effects of inorganic lubricant additives such as graphene and organic lubricant additives such as tri-(2-octyldodecyl) phosphate to be investigated by rigorous MD modeling and simulation studies"--Abstract, page iii.
