Unmanned Aerial Vehicles are extensively exploited for diverse applications importantly surveillance, defence and military, photography. Development of unmanned amphibious vehicle with integrating features of hovercraft principles and multirotor to navigate along and above the water surface, land surface and flying in the air is challenging demand. This article presents conceptual design of amphibious vehicle for the payload capacity of 7 kg with an endurance of 20 minutes and provision for mounting water sampler to collect water samples in remote water bodies. Structural strength characteristics of each part of the amphibious vehicle and integrity of same are analysed by Finite Element Analysis. FEA results indicated that the designed amphibious vehicle structure is well within the stress limit and minimal displacement is obtained. Based on structural analysis materials for various parts of the amphibious vehicle are determined and integrated structure is analysed.

Standard samples of metal powders of various chemical composition were made for mechanical tests by selective laser melting. The paper describes an increase in strength characteristics of all samples made by melting comparing with similar parameters of monolithic samples of identical chemical composition. It is established that ultrafine-grained structure and condensation of nanoparticles could be cosidered factors of strength increase.

Structural Powder

Durability and reliability of machines and mechanisms depends on the structural strength of the products from which they are made. The main requirement for any product is trouble-free operation under the conditions of the established operational period. This determines the requirements for structural materials, the main of which are technological, operational and economic. The production of sintered powder products ensures the lowest energy consumption and the lowest waste. The introduction of carbon into powder materials significantly increases the strength characteristics of the product.

The quality of hoof horn is related to 3 factors: architecture of the Stratum corneum (number of tubules and inter-tubular space), cellular factors (type of keratinization, orientation of keratin fibres) and inter-cellular factors (amount and chemical composition of the inter-cellular substance (Pellman et al., 1993). Kempson and Logue (1993) related poor hoof horn quality at 1 month before calving to the occurrence of moderate to severe solar haemorrhage at 10 to 20 weeks after calving. The objective of this experiment was to develop the use of texture analysis as a method to measure the structural strength of hoof sole tissue and assess the influence of sample width and bruising on structural strength.

Waste Particles

Polymer composites containing filler of waste dust from power production were studied. Waste particles were mechanically treated at room temperature for 30 minutes and the influence of mechanical activation on particles size distribution, chemical composition, and shape was established. Composites’ strength characteristics (bending, compressive and impact strength) were tested depending on the amount of waste dust in the composite. The optimal results were achieved at waste concentrations up to 10 wt. %.
