AB  - The high level of worthiness of unmanned aerial vehicles (UAV), particularly in everyday life, is something that will be common thing in close future. The design solutions for UAV us subject of constant innovation, focused on the improving structure performances and weight reducing. The use of new materials. like various composites, is necessary during this process to fulfill such demanding structural design requirements. Despite the fact that such kind of composite made UAV structures are subjected to the detailed calculation procedures and experimental verifications in the design phase, the fracture and failure can occur during testing in real operation conditions. The redesign procedure is required in order to overcome the noted issues.This paper describes failure analysis, as well as structural redesign procedure for a beam element of an unconventional UAV. The fracture analysis is based on the numerical calculations of the deformation and stress state of the element, as well as experimental investigation of material characteristics. The developed redesign solution contains modifications in material of the element, as well as the changes in the structure design of the failure zone. The Finite Element Analysis is performed and discussed for both of the element structures: original design and redesign based on the fracture analysis. The conclusions obtained by the comparison of these Finite Element Analyses show the significant structure improvements in the stress concentration zone, achieved by the proposed redesign.

AB  - Many new requirements in the field of experimental mechanics, like testing of metallic materials, emphasize traceability and accuracy of test results as the end goal. These requirements have energy efficiency context too, due to the increase of mass productions of many finished and semi-finished products based on steel metallurgy. Combined, both of the above-noted perspectives impose the need for improvements of some of the existing test methods. This paper describes one such improvement, the developing of the new insert tool for testing of shear strength of the welded fabric, for civil engineering. The developed tool allows repeated testing of welded joints sampled from the welded fabric of different dimensions without tool changes and is generally related with the procedure for the determination of shear strength properties of different sizes of wires used for welded fabric. The construction of the tool insert allows aiming high operation safety and higher accuracy of results, which is described in detail. The paper also presents experimental results and the Finite Element Analysis performed in order to verify the impact of insert tool application on the testing results. The obtained results and conclusion about the possible contributions of the developed insert tool for extensively testing of welded fabric for civil engineering are discussed.

This paper presents a brief overview of uncertainty sources in the laser-Doppler anemometry measurements. Special attention is paid to estimation of laser-Doppler anemometry measuring volume positioning in cylindrical pipe flow due to optical aberrations, caused by the pipe wall curvature. The hypothesis, that in the central part of the pipe (r/R  lt  0.6) exists a small, or negligible pipe wall influence on laser- -Doppler anemometry measuring position, is investigate. The required corrections, for measurements of axial, tangential, and radial velocity components such: shift of measuring volume and its orientation are analyzed and determined for used test rig and for some other pipe geometries.

AB  - Many sources of uncertainties are inherent in LDA practices and must be recognized to obtain good experimental results. Analysis of uncertainty, for tests that include LDA measurements of velocity vectors in wind tunnels or in cylindrical pipe swirl flows is very complex problem. An overview of the most significant uncertainty sources in the LDA measurements is presented. One of the main groups of uncertainty sources is determined by the optical components arrangement. In this paper, special attention is paid to estimation of laser-Doppler anemometry uncertainty of measurement volume positioning in test devices caused by the wind and water tunnel windows thickness, or by the pipe wall curvature (without using refractive index matching). The required corrections, for measurements of velocity components such: shift of measuring volume and its orientation are analyzed and determined for VTI wind and water tunnels and for some very often used geometry of cylindrical pipes in industry. Depending on different experimental conditions, some of these sources of uncertainty may be neglected, but generally, it is necessary to take
into account all of them in all optical methods, as LDA, PDA, PIV and so on.
