Experimental results obtained from cascades and one stage compressor performance tests before and after erosion were used to test a fault model to represent erosion. This model was implemented on a stage stacking program developed to demonstrate the effect of erosion in a multistage compressor. The effect of the individual stage erosion on the overall compressor performance is also demonstrated.

Abstract This article proposes a method for optimally approximating real values with rational numbers. Such requirements arise in the design of various types of gear sets, where integer numbers of gear teeth force individual stage ratios to assume rational values. The kinematic design of an 18-speed gearbox, taken from the literature, is analyzed and solved using the proposed method. The method, called sequential exhaustion, sequentially considers each stage of the gearbox design, exhaustively examining each stage. Examination of 94 solutions leads to a pareto-optimal set containing 11 solutions. Further, although the layout of the gearbox is predefined for the kinematic design problem, certain solutions of the problem exhibit “non-reducing” gear pairs, revealing previously unforeseen changes in the gearbox layout.

SummaryA method of calculation is developed to compute the overall performance of a multi-stage axial compressor, from a knowledge of the individual stage characteristics, by a “stacking” technique. Compressor models are designed and their overall performance calculated. These results are compared to show, qualitatively, the effect of alterations in design and stage performance on overall performance and to find how compressors should be designed for optimum performance.

The authors report their experience in the treatment of the "critical ischemia" in 8 patients with arterial occlusion of the lower limbs in endarteritis obliterans. All patients were treated by thickening of the tibia using the Ilizarov apparatus for distraction osteosynthesis. In all cases the operative treatment ensured lowering of the amputation level, forming of the functional stump and long-lasting remission of the illness.

Research objective was the estimation of combination distraction osteosynthesis with bone plastic in treatment of children with congenital lower limb discrepancy. Results of surgical treatment of 26 children (17 girl and 9 boys) with congenital lower limb-length discrepancy are analyzed. The method consists in creation of superfluous osteogenesis in the field of prospective lengthening. The control group included 10 patients with whom lengthening was carried out by typical way. Results: at the analysis of roentgenograms faster formation of a new bone has been revealed in basic group (on the average for 7,8 days faster on each centimetre of lengthening). Combination of distraction osteosynthesis and combined bone plastics shortened the treatment period by accelerating new bone regeneration during distraction osteogenesis of the children with congenital low limb-length discrepancy.
