In this paper a versatile and easy to use approximate procedure was used for the estimation of mode I stress intensity factors in case multiple surface cracks three dimensional elastic body, subjected remote uniaxial tensile loading. The mentioned method uses known solutions either 2D or 3D configurations containing only one crack, takes into consideration interaction effect between cracks. This procedure, which is based on principle superposition, applied configuration with coplanar...
Aerodynamic drag force breakdown of a typical transport aircraft shows that lift-induced can amount to as much 40% total at cruise conditions and 80-90% the in take-off configuration. One way reducing is by using wing-tip devices. By applying several types winglets, which are already used on commercial airplanes, we study their influence performance. Numerical investigation five configurations winglets described preliminary indications aerodynamic performance provided. Moreover, advanced...
Abstract The importance of full-scale testing in the development process for composite laminated materials helicopter blades is discussed and illustrated by means two examples drawn from Aeronautical Department, Faculty Mechanical Engineering’s experience use composites a wide variety structural applications. Laboratory fatigue conducted at Department on all flight-critical dynamic components order to determine adequacy. In this paper, analyses behavior main rotor blade light multipurpose...
The tests of the standard models serve to confirm overall accuracy and repeatability measurements in every single wind-tunnel facility confidence results obtained. intention authors this paper is present, with exemplary test results, a methodology for certification verification reliability T-38 Military Technical Institute's trisonic wind tunnel on basis check testing together small number repeat-run sets prior customer's tests. Wind-tunnel data uncertainty considered form few presumably...
The establishment of exact two-dimensional flow conditions in wind tunnels is a very difficult problem. This has been evident for all types and scales. In this paper, the principal factors that influence accuracy tunnel test results are analyzed. influences Reynolds number, Mach number wall interference with reference to solid blockage (blockage wake) as well side-wall boundary layer control Interesting brought light regarding effects model versus facility subsonic transonic flow.
The requirements for the accuracy of measurements in a wind tunnel test become more and severe while complexity increases. In an environment reduced time available increasing costs, it is important that accurate calibrations verifications all components measurement chain facility are established, maintained statistically controlled through prolonged periods time. paper presents efforts undertaken to establish maintain system control quality T-35 4.4 m × 3.2 low-speed Military Technical...
Recent experience has shown that test results of standard wind tunnel models under off-design conditions could be a useful aid in preparations some nonstandard tests. However, reference data for such do not exist, or they are scarce. Therefore, transonic tests the HB-2 were executed VTI T-38 as supplement to supersonic same design-intent conditions, which available. New conducted so envelopes partially overlapped with those from available data. Good agreements references confirmed ranges, it...
Unmanned air vehicles (UAVs) with vertical take-off and landing (VTOL) capabilities, equipped rotors, have been gaining popularity in recent years for their numerous applications. Through joint efforts, engineers researchers try to make these novel aircraft more maneuverable reliable, but also lighter, efficient quieter. This paper presents the optimization of one vital parts, composite engine mount, based on genetic algorithm (GA) combined defined finite element (FE) parameterized model....

In this paper, the experimental results of structural vibratory testing for light multipurpose helicopter main rotor blade composite laminated materials are presented. The aim was to define basic aeroelastic properties blade. This included determination natural oscillation modes and frequency structure in oscillations, as well defining damping. measurement performed three different full scale models with types cores blade: Rohacell 71 polyurethane foam, Nomex aramid honeycomb phenolic...
