HSound radiation from infinite laminated composite shell with periodic rib stiffeningA theory of sound radiation from an infinite cylindrical shell which is stiffened periodically by ribs is given. Both shell and ribs are laminated composites. The shell is modelled by the differential equations of a thin shell theory. The flexible ribs, which exert both forces and moments on the shell's surface, are modelled by thin conical shell finite elements; degrees of freedom other than those at the shell's surface are removed by receptance methods. Excitations are time-harmonic mechanical forces at arbitrary points on the shell's surface and ribs, and acoustic monopoles in the exterior and interior fluids ...

This memorandum presents the results of a series of experiments that measured the decay time histories of a model frigate free to move in the vertical plane, in an attempt to identify where the problems might be occurring. Judgements are made concerning the components in the heave and pitch motions using the terms in the full two dimensional strip theory heave and pitch motion equations to explain the trends shown. The investigation has shown that the sectional damping coefficient appears to be over predicted. This results in a relatively poor prediction of heave decay curves at low speed and over estimates the damping in the pitch decay curves. It appears that the discrepancies seen in the heave and pitch transfer functions could be due to the wave excitation being predicted incorrectly31ocn035507748book19921.00Randell, G.

SHeat Transfer and Aerodynamics of a 3D Design Nozzle Guide Vane Tested in the Pyestock Isentropic Light Piston FacilityIn HP turbines, predictions of the heat transfer to the blade and endwalls is particularly important for an accurate assessment of turbine component life. On the endwalls, there are often complex 3D (secondary) flows present which make predictions of heat transfer particularly difficult, A detailed investigation of this area has been carried out on a fully annular cascade of highly 3D nozzle guide vanes. Measurements were made on the vane and endwalls to determine heat transfer and aerodynamic chacteristics. Testing was conducted in a short duration Isentropic Light Piston test facility, at engine representative Reynolds number, Mach number and gas-to-wall temperature ratio. Interpreted test data are compared with computations obtained at test conditions22ocn059903856art1992King, I.

A3D Pneumatic and 2D Dynamic Probes: Their Development and Subsequent Use in a Transonic FanThree different 3D pneumatic probes have been built and calibrated in detail, along with two dynamic yawmeters and a geometrically identical pneumatic yawmeter. This paper discusses the aerodynamic performance of the probes and compares detailed steady-state flowfield measurements taken with the probes at stator exit in a transonic fan. C148 transonic fan research is supported by the MOD Strategic Research Programme and the Aerospace Division of DTI ...

The main aims of the working party were to review specimens commonly used to generate fatigue and fracture data and to recommend specimens to be used in the future for a wide range of test purposes. This report defines a selected number of laboratory specimens which are recommended for future use in fatigue and fracture testing of metallic materials and joint configurations. It also defines a small group of core specimens which should be preferentially chosen when assessing the fatigue and fracture qualities of a particular material or of a particular structural feature. Guidelines are given on dimensional changes which may be needed for specific requirements. Advice is also given on specimen manufacture and assembly methods81ocn048161900book1994Great BritainDefence Research Agency51ocn028333241book19920.47DMA guide to the DRA : the Defence Research Agency11ocn027956268book19930.47Great BritainMinutes of proceedings on the draft Defence Research Agency Trading Fund Order 199311ocn047623142art20001.00Hepden, ChrisPaying dividends : defence research benefits ITS11ocn034338590book19950.47Great BritainAnnual report and accounts, 1994-9511ocn031069481book19940.47Great BritainAnnual report and accounts, 1993-9411ocn027988967book19930.47Great BritainThe Defence Research Agency Trading Fund Order 199301ocn315973921book1991Great BritainFramework document April 1991Fri Mar 21 15:57:51 EDT 2014batch16944
