Real Gas Simulations of a Sub-Scale Liquid Rocket Engine
ISBN: 9783639199031 / Angielski / Miękka / 168 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The prediction of transient phenomena
inside liquid rocket engines has not been feasible until now because of the many challenges posed by the operating conditions. Especially, the departure from ideal gas (because of cryogenic injection) is one of the major hurdle for such simulations. In order to begin addressing these issue, a real-gas model has been implemented in a massively parallel flow solver. This solver is capable of performing Large-Eddy Simulations in geometrical ...

The Damage Tolerance of Warp Knit Fabric Polymer Composites
ISBN: 9783639234787 / Miękka / 248 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Multiaxial Warp Knit (MWK) fabrics have brought together the advantages of textile technology: high deposition rates, unlimited shelf-life, low cost and improvement in damage tolerance. The effect of stitching architectures of such fabrics is reported in this work. Three stitch architectures of carbon MWK, in epoxy matrix, were considered. Damage resistance and tolerance testing were carried out on dry and aged samples along with DMTA, FTIR, Raman Spectroscopic analysis. Investigations showed that during low energy impact high stitch density offered more damage resistance, being directly...

ISBN: 9780792392651 / Angielski / Twarda / 285 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Robotic technology offers two potential benefits for future space exploration. One benefit is minimizing the risk that astronauts face. The other benefit is increasing their productivity.
Realizing the benefits of robotic technology in space will require solving several problems which are unique and now becoming active research topics. One of the most important research areas is dynamics, control, motion and planning for space robots by considering the dynamic interaction between the robot and the base (space station, space shuttle, or satellite). Any inefficiency in the planning and... Robotic technology offers two potential benefits for future space exploration. One benefit is minimizing the risk that astronauts face. The other bene...

Influence of Purge Flow on Performance of an End Wall Profiled Turbine
ISBN: 9783838114675 / Angielski / Miękka / 184 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The goal of this study is the investigation of the promising secondary flow control technique of non-axisymmetric end wall profiling in a more engine representative environment. In this work end wall profiling is applied to the first stage of a high work, 1.5 stage, unshrouded turbine. Without purge flow non-axisymmetric end wall profiling has demonstrated a considerable increase of total-to-total efficiency. The two designs increased the total-to-total efficiency by 1% and 0.3% respectively relative to a baseline efficiency of already 91%. The first end wall design having the...

Vibration Analysis of Cracked Composite Aircraft Wing Modeled as Shell
ISBN: 9783639266924 / Angielski / Miękka / 120 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. An analytical model of cracked composite shell is developed to study the characteristics of the natural vibration of composite aircraft wing in relation to crack position and orientations. Also, the analysis incorporates the effect of stacking sequence of the composite lamina and volume fraction of fiber to matrix response to natural vibration. The composite wing is modeled as a shell using ANSYS software. The local flexibility approach based on linear fracture mechanics is used to model the crack and a local compliance matrix at the crack location is derived. Changes in natural frequencies...

Ces patrons peuvent etre formalises a l'aide de langages formels comme AltaRica. Dans notre cas, les motifs correspondent a des abstractions d'architectures concretes et donc requierent une modelisation plus declarative. Les proprietes etudiees etant...

Influence de la R�compense Et de l''�ge Sur La Performance de Pilotage
ISBN: 9786131520792 / Francuski / Miękka / 272 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Dans le cadre de l''activite de pilotage, les contraintes cognitives liees au fonctionnement cerebral demeurent encore peu considerees. Pourtant, lorsqu''elles sont comprises, l''erreur humaine devient un symptome des carences du systeme. Une approche originale et innovante pour traiter l''erreur humaine en aeronautique est d''utiliser les outils et les concepts des neurosciences integratives et de la neuropsychologie. Les travaux de ces disciplines suscitent depuis peu l''interet des facteurs humains et ont donne recemment naissance a un nouveau courant aux Etats-Unis: la neuroergonomie....

Aircraft Structural Safety
ISBN: 9783639193398 / Angielski / Miękka / 308 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Aircraft structural safety is achieved by designing the structures against uncertainty and by taking steps to reduce the uncertainty. Safety factors and knockdown factors are examples of measures used to compensate for uncertainty during the design process. Uncertainty reduction mechanisms (URMs), on the other hand, may be employed during the design process or later on throughout the operational lifetime. Examples of URMs for aircraft structural systems include structural testing, quality control, inspection, health monitoring, maintenance, and improved structural analysis and failure...

Les and Rans Around Bluff Body
ISBN: 9783639276909 / Angielski / Miękka / 116 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book focuses on the use of Large Eddy Simulation (LES) and Reynolds-averaged Navier-Stokes (RANS) to simulate the flow around elliptical bluff body with blunt trailing edge fitted with open base cavity. The main objective of this study is to determine the effects of the cavity on the drag of the body. A secondary but important objective is to demonstrate that LES can provide accurate representation of the flow around this bluff body. Moreover, LES results can complement the available experimental results in order to provide a much better understanding of the flow. The simulations were...
