|
 | The response of porcine adipose and skeletal muscle tissues to shock compression has been investigated using the plate-impact technique in conjunction with manganin foil pressure gauge diagnostics. This approach has allowed for measurement of the levels of uniaxial stress imparted to both skeletal muscle and rendered adipose tissue by the shock. In addition, the lateral stress component generated within adipose tissue during shock loading has also been investigated. The techniques ... |

|
| The rising importance of acquisition has generated a need to complement this development with a far wider research agenda. Historically, economic and commercial theoretical frameworks have dominated how procurement is conceptualised. While these conceptualisations will remain foundational in terms of measuring outcomes, they offer little by way of understanding the enablers, such as people, that facilitate the achievement of particular outcomes. Recent advances in public procurement practices have been sufficiently ... |

|
| The paper analyzes, from a predominantly UK perspective, the implications for the U.S. of the November 2, 2010, Anglo-French Defence Cooperation Treaty. The current pressures on British and French defence budgets were the primary driving force behind this cooperative effort. London and Paris have made steps toward improving joint efforts in a number of areas with defence acquisition and industrial cooperation being prominent. In the UK, there appears to be ... |

David Moore; Peter Ito; STUART YOUNG; Kevin Burgess; Peter Antill; CRANFIELD UNIV (UNITED KINGDOM)
|
| The research assessed the international impact of the U.S. export control and technology transfer regime, with a focus on the UK experience with the U.S. requirements as they relate to the Joint Strike Fighter (JSF) and the impact on logistical support for the JSF fleet. UK government and industry representatives indicated agreement with the goals of U.S. policy, skepticism regarding the impact of those policies on effective project management, and ... |

|
| The panel discussion will address four critical defence acquisition issues and programmes which illustrate the innovative approaches the United Kingdom is undertaking in this area. All four cases will echo the challenges facing the US and other countries and provide valuable lessons learned in a number of key areas. The first topic is the UK decision to acquire C-17 transports, which provides a good example of the benefits of capability ... |

| Implicit Large Eddy Simulation for Unsteady Turbulent Flows |

9 pages |
| Authors:
Marco Hahn; Dimitris Drikakis; CRANFIELD UNIV (UNITED KINGDOM)
|
| A numerical investigation of high-resolution schemes for solving the compressible Navier-Stokes equations in the context of Implicit Large Eddy Simulation (ILES) is presented. Computations have been performed using a hybrid total variation-diminishing (TVD) scheme. The hybrid TVD scheme combines third-order Godunov-type fluxes with first-order (dissipative) schemes using the flux limiters approach. Results are presented from numerical experiments of turbulent flow past an open cavity. |

| This report results from a contract tasking Cranfield University (RMCS) as follows: The Grantee will investigate various mathematical concepts of detection and characterization of simulated radar signals. As detailed in the technical proposal at least four approaches will be investigated: 1. A varied matched filter and spectral analysis 2. A neural network (NN) approach based on the use of NNs to detect pulse radar. 3. Methods derived from CDMA (code ... |

|
| A preliminary assessment has been made of a combustor in which the reaction is stabilized in a porous, incombustible medium. Its performance at elevated pressures and inlet temperatures has been studied with emissions and stability determined over a wide range of conditions together with the pressure loss and diffusivity of the porous matrix elements from which the combustor is made. The combustor was formed of reticulated porous ceramics, untreated to ... |

| Thermal barrier coating are perceived as an enabling technology to increase the performance of, improve efficiency within, and lower the emissions from modern gas turbines. To fully utilize this capability one has to be able to accurately predict the life of these coatings under conditions relevant to gas turbine service. This paper addresses the failure of TBC systems as a result of erosion and foreign object damage. Laboratory studies under ... |

|
| A new approach to the prediction of crack growth fatigue lives under variable amplitude loading, the K(PR) approach, is described. K(PR) is the minimum stress intensity for crack propagation during a loading cycle and is sensitive to the immediate loading history at the crack tip. Four parameters describe changes in K(PR) as a function of load history. Unlike other models the KPR model has no fitting parameter. The four KPR ... |
