Pronk, Z. (author), Prins, J.J.M. (author)The purpose of this document is to identify applications for the European Real-time Operations Simulator, EuroSim. First, the document provides an overview of the functional capabilities of the EuroSim. An executive summary of the EuroSim tool is given dealing with what it is, its current status, and what it will become. A list of possible...report 1996

van den Assem, D. (author), Kramer, A.J. (author)This document contains the description of the assessment of configuration concepts for an optically induced fluorescence detector, to be used on a miniaturized Capillary Electrophoresis (CE) instrument. The assessment is concluded with the selection of a concept for further instrument design and breadboarding. The selected concept consists of...report 1996

Khatwa, R. (author), Roelen, A.L.C. (author)This investigation focused on the identification and analyses of factors that are potentially associated with fatal Controlled Flight Into Terrain (CFIT) accidents involving commercial operators. Central to the objectives was an attempt to highlight differences between CFIT accidents of air taxi, regional and major carriers. The research focused...report 1996

de Jonge, J.B. (author), Bartelds, G. (author)The problems of Ageing Aircraft are worldwide. Hence, actions to overcome or prevent these problems should be taken in international collaboration. The Federal Aviation Administration FAA and the Netherlands Civil Aviation Department RLD have signed a Memorandum of Cooperation in the area of structural integrity, with specific reference to...report 1991

Pinches, C.L. (author), Kuijpers, E.A. (author), Spaan, F. (author)Microgravity experiments operated using telescience concepts face certain constraints. The effect of these constraints on the focusing task are identified. Four types of focusing strategy, which provide a natural means of focusing in the presence of these constraints, are described. Three specific strategies are implemented as part of the...report 1991

Hounjet, M.H.L. (author)A method is presented for the generation of 0-type grids about transverse cross-sections of transport type aircraft. The method combines a hyperbolic grid generation scheme with source terms obtained with a boundary element method in such a way that 0-type grids around fairly complex shapes with concavities can be generated easily. The...report 1990

Pike, J. (author)The combustion of multi-tube propellant grains is represented either by the Corner form function or an exact parallel burning layer expression. The exact expression predicts significantly different burning characteristics near the end of the burn to that of the Corner form function. When used in a typical gun firing calculation, the exact...report 1990

Prins, J.J.M. (author), Dieleman, P. (author), van Woerkom, P.T.L.M. (author)The Hermes manipulation system (HERA) is a sophisticated space manipulator system, which has to perform tasks ranging from berthing to tool operation in various operational modes from fully automatic to purely manual. Development and qualification of such a space-based manipulator must be supported by computer simulation facilities. The HERA...report 1989

Vreeburg, J.P.B. (author)In order to generate constructive discussion on the use of the Space Station for scientific purposes, a possible realisation of operations management is presented. The realisation is chosen to deal with the two main user concerns viz. realtime experiment control and priority allocation in experiment scheduling. From Spacelab it is known that the...report 1989

Sevenhuijsen, P.J. (author)For the measurement of in-plane deformations and of out-of-plane deformations different grid methods are available. Digital image measurement systems provide a new future for grid methods: they considerably improve speed and accuracy. The paper discusses basic features, practical solutions and future possibilities.report 1989

Visser, F.B. (author)In the future Columbus in-space facility, the communication between the crew and the various system elements will mainly take place via the so called Crew Workstation (CWS). The CWS hardware will comprise a versatile set of I/O devices which enable the clear and unequivocal presentation of information to, and the easy issue of commands by crew...report 1988

Fennell, P.J. (author), Harris, J.R. (author), Muir, H.C. (author)Five hundred passengers participated in an investigation into their knowledge of the pre-flight briefing and the safety card information. Although general knowledge was good (78%), a tendency was observed for passengers to overestimate their ability to recall some aspects of the pre-flight briefing and safety card. Males had a higher score on...report 1988

Hounjet, M.H.L. (author)A description is given of the method CAR88 for the calculation of steady and time-linearized unsteady subsonic and supersonic flow about complex 2-D and 3-D configurations. The method belongs to the category of the socalled panel methods. Results of applications in supersonic flow are shown which have been made to a 2-D oscillating flat plate, a...report 1988

Wanhill, R.J.H. (author), Schra, L. (author)The economic life of airframes is largely determined by widespread initiation and growth of fatigue cracks at low stress intensities. Any factor reducing the low stress intensity fatigue damage rate could, if controllable, increase the structural durability. One such factor is corrosion fatigue crack arrest. Corrosion product build-up within a...report 1988
