Wanhill, R.J.H. (author)The requirements and problems of high temperature materials in gas turbines are reviewed, with specific reference to turbine discs, blades, vanes and combustion cans. The mechanical and environmental property requirements of these components are discussed, followed by an overview of the types of materials used. Lastly, there is a summary of the...report 1975

van der Vooren, J. (author), Sanderse, A. (author)A uniaxial flat front--"theory is presented for a gas loaded variable conductance heat pipe. The theory takes into account the inertial effects of the moving vapour, which can grow large under certain circumstances, but neglects the axial heat conduction of the wall and wick. A limited number of numerical examples indicates excellent agreement...report 1980

Mom, A.J.A. (author)This paper consists of two parts. In the first part, concerning operational conditions in gas turbines, the following topics are covered: - the magnitude of temperatures, temperature profiles, and stresses in various components - transient temperature conditions, occuring as a result of e.g. throttle setting changes and affecting thermal fatigue...report 1981

Delil, A.A.M. (author)Radiation heat transfer is a non-negligible physical process in an open-cycle magnetohydrodymic generator. It constitutes an important part of the energy conservation law, one of the fundamental equations describing the behaviour of the MHD combustion gas in the generator. Radiation heat transfer is modelled following the generally accepted...report 1983

van Leeuwen, H.P. (author)The concept of fugacity is explained. Application of compressibility and fugacity data in hydrogen embrittlement calculations is discussed. Equations of state are reviewed. Compressibility factors and fugacity coefficients are calculated. A best estimate is proposed.report 1983

Delil, A.A.M. (author)A uniaxial model for the transient performance of gas-loaded variable conductance heat pipes is being developed, partly under contract with the Netherlands Agency for Aerospace Programs NIVR. The model has to be easily implementable in existing spacecraft thermal analyzer computer programs. So far, a steady-state version of the model is...report 1984

Prins, J.J.M. (author)The testing of Spacecraft Attitude and Orbit Control Subsystems is described from the early design up to in-flight, inclusive. Main topics dealt with are: description of three generic AOCS test classes, model philosophy, standardization, subsystem static test methods, subsystem dynamic test methods, generic test equipment and test facilities....report 1984

Maccagno, T.M. (author)SiaN4 and SiC based advanced ceramics that have been produced by hot isostatic pressing (HIP'ing) have good potential to be used as hot section components in gas turbine aero engines. This report provides background for an NAE-SML investigation of this potential. The report begins with a general overview of the many fabrication methods that have...report 1989

Kolkman, H.J. (author)Deposits are regularly removed from compressor blades and vanes of installed jet engines and gas turbines by compressor washing. Hereby a compressor cleaner is sprayed into the compressor while operating at reduced or normal r.p.m. Recently developed compressor cleaners are claimed to be ecologically sound. In addition, many new compressor...report 1991
