Opis:
This article presents a model of a rope, which is an example of a rope used when a glider takes off by means of towing with the use of an aerial winch, winding the rope attached to the glider. The finite element method used in MESH software was used for the model. This method allows us to take into account not only bending flexibility but also longitudinal flexibility. Such an approach to the subject of simulation allows for obtaining results relatively quickly while maintaining an appropriate level of accuracy. This allows for further exploration of the phenomena occurring in the glider towing process. The construction of a fast algorithm enables its implementation in the glider towing process control systems. The aim of this article is to present numerical analyzes of commonly used tow ropes. This paper presents the results of the analysis of the synthetic rope commonly used in gliding, comparing the obtained results with the classic steel rope.

Opis:
Flight training is occupied by many hours of theoretical and practical training. Polish universities offer the possibility of conducting the aforementioned training as part of academic training. A young aviation student, implementing himself in this process, takes on the burden of academic training and aviation training. The aviation environment is sensitive to safety issues. These include the occurrence of incidents, events, and aviation accidents. This issue arises directly from the possibility of endangering the health and lives of bystanders as well as aviation personnel and the damage or destruction of aviation equipment. In addition, there are issues related to the immobilization of airports, aviation organizations, excess repairs, or cases settled in court. Despite all the above, it should be mentioned that air transport is described as the safest means of transportation where – although incidents, events, or high-profile crashes are occasionally recorded. It is desirable for personnel to remain as focused as possible during aviation tasks. The multitude of tasks carried out by aviation students, combined with the burden of academic study, can carry a significant impact on maintaining concentration, lowering perception, or at least meticulousness. These topics correlate closely with the human factor. As a research problem, the submitted work was adopted to determine the impact of academic teaching load on the safety of aviation activities performed, in the context of aviation training provided at universities. The research included aviation mechanics and aircraft crews within its scope.

Opis:
Flight safety, which characterizes the aviation industry, is an important element that contributes to increasing the trust of customers and passengers. The aforementioned factor closely corresponds to the reliability of aircraft and their individual components, including power units. Over one hundred years of development of aviation techniques has led aviation to the currently observed level of safety and reliability. Aviation techniques should be understood as technologies as well as local and global regulations affecting individual branches of the industry. Guidelines No. 9 of the President of Polish Civil Authority of August 29, 2016 on the inter-repair periods of piston engines, indicate the possibility of waiving the requirements related to the performance of major repairs, and a number of conditions must be met. One of the requirements set out in the Guidelines is performing a spectrographic analysis of engine oil in order to estimate the rate of wear of individual engine parts (ULC, 2016). The main goal of this study was to recognize whether regular analysis of engine oil may affect the assessment of the technical condition of aircraft piston engines based on the example of ROTAX 912S, thus affecting or not influencing the maintenance intervals. The engines referred to in the research were produced in the amount of about 2,000 units. Thus, these engines gained popularity as power units for airplanes, helicopters, and gyroplanes. With the increasing number of ROTAX units introduced into service, research into the technical condition becomes more important due to their percentage share in the market.
