  • Wake affected boundary layer flows within an embedded stage of a multi-stage axial compressor 
    Lee, D. Y. (2001-06)
    Boundary Layer Flows in turbomachines have been recognised to crucially influence the stability and performance of gas turbine components particularly the compressor since its function is to provide a pressure rise through ...
  • Wake Vortex Modelling and Simulation for Air Vehicles in Close Formation Flight 
    Saban, Deborah (Cranfield University, 2010-01)
    The aim of this research is to develop realistic models of aerodynamic cross-coupling e ects that can be incorporated in real-time or near real-time simulations of Unmanned Aerial Vehicles (UAVs) in close formation flight. ...
  • Wall pressure fluctuations under turbulent boundary layers at subsonic and supersonic speeds 
    Lilley, G. M. (College of Aeronautics, 1963-03)
    The problem of pressure fluctuations at a rigid wall under a turbulent boundary layer has attracted much attention in the past decade. At low Mach numbers the theory is well established from the work of Kraichnan and ...
  • Warehouse model: report no. 1 
    Kay, E. (College of Aeronautics, 1966)
    1.1 The purpose of the research project has been outlined in Appendix 5 of the report to the Research Fellowship Council Meeting on 10th November, 1955. 1.2 In this first report we consider the simplest model of a ...
  • Warehouse model: report no. 2 
    Kay, E. (College of Aeronautics, 1966)
    1.1. Report No. 1 dealt with the simple warehouse model in a static sense. This was sufficient, the only consideration being optimisation of handling, i.e. the problem posed was spatial. The problem becomes a dynamic ...
  • Water flow on accreting ice surfaces 
    Charpin, Jean P. F. (Cranfield University, 2002-09)
    Ice growth may rapidly degrade the aerodynamic performance of an aircraft. It can also severely damage structures such as communication towers or power lines. Subsequently, de-icing and anti-icing systems have been ...
  • Water ingestion effects on gas turbine engine performance 
    Nikolaidis, Theoklis (Cranfield University, 2008-10)
    Although gas turbine engines are designed to use dry air as the working fluid, the great demand over the last decades for air travel at several altitudes and speeds has increased aircraft’s exposure to inclement weather ...
  • Water injection in the normally-aspirated piston engine 
    Goodger, E. M. (College of Aeronautics, 1957-03)
    The injection of water into a spark-ignition piston engine tends to reduce both the power and the tendency to knock. Because of the latter effect the conditions of operation can be made more severe in order to realise ...
  • The wave drag of highly-swept wings: a comparison of linear theory and slender body theory 
    Nonweiler, T. (College of Aeronautics, 1954-10)
    This note comments on the comparison between the answer obtained by linear theory for the wave drag of slender-wings (as interpreted by the limit and that value for the drag obtained by Slender-Body Theory. It is shown ...
  • Wave reflection near a wall 
    Robinson, A. (College of Aeronautics, Cranfield., 1950-05)
    The field of flow due to a shock wave or explanation wave undergoes a considerable modification in the neighbourhood of a rigid wall. It has been suggested that the resulting propagation of the disturbance upstream is ...
  • Weak compression waves in relaxing gases 
    Scott, E. M. (Cranfield University, 1972)
    Studies have been made of the structure of weak compression (shock) waves in relaxing gases. These studies have been primarily concerned with the development of separate theoretical and experimental techniques. These ...
  • Weld toe stress concentrations in multi-planar stiffened tubular KK joints 
    Woghiren, C. O.; Brennan, Feargal P. (Elsevier Science B.V., Amsterdam., 2009-01-31)
    This paper reports a parametric stress analysis of various configurations of rack plate stiffened multi-planar welded KK joints using the finite element method. The KK joint finds application in the leg structure of ...
  • Welding embrittlement of the parent plate outside the visible heat affected zone region 
    Coward, M. D. (College of Aeronautics, 1968-04)
    Enbrittlement of steels outside the visible heat affected zone region due to plastic straining from the weldment and subsequent ageing has been reported by several authors. The problem is reviewed in this Note and ...
  • Welding in aircraft structures 
    Apps, R. L.; Gourd, L. M.; Jubb, J. E. M. (College of Aeronautics, 1966)
    The welding processes relevant to the welding of aircraft materials are briefly reviewed, together with those materials of present or future interest for aircraft structures. The problems of design for welding are also ...
  • WENO schemes on arbitrary mixed-element unstructured meshes in three space dimensions 
    Tsoutsanis, Panagiotis; Titarev, Vladimir A.; Drikakis, Dimitris (Elsevier, 2010-11-23)
    The paper extends weighted essentially non-oscillatory (WENO) methods to three dimensional mixed-element unstructured meshes, comprising tetrahedral, hexahedral, prismatic and pyramidal elements. Numerical results illustrate ...
  • Wet Gas Flow Metering with Pattern Recognition Techniques 
    Jama, Ali Ahmed (2004-04)
    The development of many gas condensate fields and the increasing number of marginal fields whose economics do not support conventional bulky separation and processing facilities means that new wet gas flow metering ...
  • Wheat video experiments 2000 data archive 
    Hobbs, Stephen; Seynat, Cedric (2000)
    Observations of wheat motion in wind were made through the later part of the growing season (June - August) for wheat on Cranfield Airfield in 2000. The data collected include stereo videogrammetric measurements of the ...
  • Where safety culture meets national culture: the how and why of the China Airlines CI-611 accident 
    Li, Wen-Chin; Harris, Don (Ashgate, 2006-12-01)
    There has been a great deal of research regarding the relationship between national culture and aviation safety. Soeters and Boer (2000) suggested that safety was enhanced when national culture was more individualistic in ...
  • Wideband measurement of transistor small signal parameters by time domain spectrometry 
    Young, G. M. (College of Aeronautics, 1969-04)
    Time Domain Spectrometry (TDS) Methods are outlined and their application to measurement of transistor parameters is discussed. Experimental results are presented and the advantages and limitations of TDS methods are ...
