“…Another element of the aero structure that was subjected to tests was the vertical stabilizer of the M28 Skytruck plane. The details of the investigations are presented in [11]. In the course of the study, two 3.6 kg gel projectiles were thrown at the element, and their speed was similar to the cruising speed of the plane.…”

The article presents the test results obtained from the “Research methods and systems for the investigation on impact resistance of elements of aero structures and land vehicles aimed at the assessment of passenger safety” R&D project that was jointly executed by the Institute of Aviation, the Institute for Sustainable Technologies – National Research Institute, and the PZL Mielec. The main objective of the project was to perform impact tests of the windscreen and the vertical stabilizer of the PZL M28 Skytruck. The experimental tests were conducted for real objects in full scale. The investigations were carried out using an original 250 mm pneumatic gun. Apart from the impact tests, the project was also focused on numerical simulations of impacts employing the Finite Element Method (test object modelling) and the Smoothed Particle Hydrodynamics methods (the model of the gelatine projectile). The authors compare the results of experimental tests and numerical simulations. They present the differences in the results obtained and analyse the reasons behind these discrepancies, and based on the analysis, they conclude that the main cause for them is the simplified mathematical model describing the behaviour of the material subjected to dynamic loads, which was used in numerical simulations.

“…To this extent, beams are mounted together, and these structures are called frames (Ansell, 2005; Antes et al, 2004; Lin and Ro, 2003; Lin and Wu, 2005; Mead, 2002; Moon and Choi, 2000; Ovunc, 1974; Rafezy et al, 2007). The most recent example of these structures in mechanical engineering can be given as three-dimensional load-carrying systems in aerospace structures that require lightweight and stiffness simultaneously (Kaiser et al, 2017; Wallner et al, 2010; Zbrowski, 2014). As assemblies of multiple beams, frame structures display similar behaviour to the beams but with a more complex nature.…”

This study analytically handles the three-dimensional free vibrations of spatial frames using the initial values method, considering the axial and shear deformations alongside rotary inertias, namely, torsional, in-plane bending and out-of-plane bending. To handle the spatial geometry, the direction cosine matrices are used. Validation is performed with three cases in total, one case available in the literature alongside two numerical examples that are solved analytically and compared to the finite element models. Excellent agreements are found between the analytical results and the results in the literature, as well as those obtained from the finite element models.

Currently, nearly 1.5 M tons of different types of glassware are produced in Poland, and the majority of it is used as packaging in the food, cosmetic, and pharmaceutical industries. The article presents a method for testing impact resistance of glassware, which was developed at the ITeE-PIB. The authors also present a prototype of a device for glassware tests, discuss a test procedure applied in such tests, and show the results of verification tests for which a high-speed digital camera was used to record the impact strength and the propagation of cracks in glassware. The device in question has been successfully implemented in an industrial research laboratory.
