The report is part of a wide ranging survey of the effects of contamination on airoplane flight control hydraulic subsystems. It analyses the current state of the problem and proposes a method by means of which long term research should be directed to obtain a general solution. It shows how the behaviour of particles in a complete hydraulic system may be represented in terms of a mathematical model based on matrix representations of both particle concentrations and characteristics of the system components. Also reported on are coincidence problems in stream scanning particle size analysis, automatic image analysis as applied to particle size analysis, the stereological representation of particles, the theoretical efficiency of non-isokinetic sampling devices, a new method for representing the efficiency of a filter, and techniques for analysing the composition of particles in a fluid.
