    The digital simulation of a turbo-charged diesel engine
    (College of Aeronautics, 1969) Shroff, H. D.; Hodgetts, D.
    A mathematical simulation of a six cylinder four stroke water cooled diesel engine is described and then used to study the changes in performance caused by variations of engine paramters and operating conditions. The results are discussed with reference to the mathematical model employed and the physical system. A limited study, to demonstrate the applicability of the simulation, considers the optimisation of a variable geometry system to achieve a performance target.

    Vibrations of the propeller shaft and the rear axle of a passenger car
    (College of Aeronautics, 19) Egbuson, A. K.; Hodgetts, D.; Hodgson, R.
    Digital analysis of the free-free bending vibrations of a propeller shaft and a beam-type rear axle are compared, for different theoretical models, with the results of rig tests. The relative importance of distributed mass, the coupling between the bending and torsional modes and the half shafts of the rear axle are discussed. The relation between the work completed and the programme of work in progress is given briefly at the end of the report.
