Opis:
Opracowanie powstało w wyniku realizacji badań naukowych w ramach projektu FP7-GALILEO-2011 -GSA-1 SHERPA „Support ad-Hoc to Eastern Region Pre-operational Actions in GNSS" [1]. Podczas implementacji nowych technik i technologii satelitarnych pojawiła się konieczność wykonania safety case, a wraz z nią problem naukowy, w jaki sposób tego dokonać. Przyjęta hipoteza robocza została zweryfikowana teoretycznie i empirycznie, a osiągnięte wyniki badań umożliwiły stworzenie nowego modelu wykonywania analizy ryzyka związanego z implementacją technik i technologii satelitarnych dla potrzeb lotnictwa oraz opracowanie na tej podstawie safety case. Model ten został następnie przyjęty na forum międzynarodowym, podczas warsztatów roboczych w ramach projektu SHERPA (Eurocontrol i GSA). W niniejszym materiale zaprezentowano tylko wybrane zagadnienia dotyczące humans factors, niezbędne w systemie zarządzania bezpieczeństwem (SMS), gdyż stanowią one przedmiot permanentnych, certyfikowanych szkoleń w branży lotniczej. Opracowany model został również pozytywnie zweryfikowany empirycznie i włączony do szkolenia kadry Wojewódzkiego Inspektoratu Transportu Drogowego. Przeprowadzone badania naukowe oraz uzyskane wyniki uprawniają do stwierdzenia, że przy implementacji rozwiązań organizacyjnych, technicznych i prawnych należy sporządzać safety case, stosując prezentowany model. Konieczne jest również uwzględnianie szkoleń omawiających hu-man factorw każdej sferze działalności człowieka jako niezbędnego elementu SMS, szczególnie w procesie zarządzania zasobami ludzkimi.
The present article is based on the findings of scientific research conducted within the FP7-GALILEO-2011-GSA-1 project, acronym SHERPA (Support ad-Hoc to Eastern Region Pre-operational Actions in GNSS"[1]). The implementation of novel techniques and technologies triggered the requirement for preparation of a safety case, while generating a scientific problem of how this should be done. The working hypothesis adopted was verified both theoretically and empirically, while the obtained results allowed the development of a new model for assessing risks related to the implementation of satellite techniques and technologies for the purposes of aviation, upon which the safety case was built. The model was adopted at the international forum during the SHERPA project workshops (Eurocontrol and GSA). This article discusses only issues related to human factors, which are essential for the Safety Management System (SMS) and the subject of permanent certified trainings in the aviation industry. The model was developed which underwent positive empirical verification and became the subject of training offered to the staff of the Voivodeship Inspectorate of Road Transport, for the first time in Poland. Based on scientific research conducted and its results, it can be concluded that the implementation of organizational, technical or legał solutions requires the safety case to be built using the model presented herein. Additionally, human factors training is an indispensable SMS element and it should be applied to every sphere of human activity, particularly those involving human resource management.

Opis:
The article describes the results of experimental research concerning a prototypical hydrodynamic clutch controlled via changes in flow rates of the working fluid. The aim of the research was to collect experimental data to confirm the practical possibility of using such a control method of the hydrodynamic clutch and to compare this with other currently used methods. A change in flow rate of the working fluid was obtained by increasing the distance between rotors. The experimental research was conducted on a test rig built specifically for this purpose. On the basis of the research, the influence of the clutch filling level, the direction of rotation and the temperature of the working fluid on the clutch torque were determined. The experimental research shows that the transferred torque is significantly influenced by the width of the gap between rotors, the rotational speed of the input shaft, the clutch filling degree and the temperature of the working fluid. Thus, these values may be used to control the torque transferred by the hydrodynamic clutch. The temperature of the working fluid is not recommended as a control value due to the fact that it is dependent on the working conditions of the hydrodynamic clutch. On the basis of the test results, it was proven that hydrodynamic clutches controlled by increasing the distance between rotors can be successfully used, for example, in drive systems of wind farms.

Opis:
The article presents experimental and theoretical studies concerning the possibility of using a controlled hydrodynamic clutch in a wind power plant’s drive system. The hydrodynamic clutch is controlled by changing the distance between the hydrodynamic clutch rotors. The control system is supposed to maintain a constant angular velocity of the electric generator shaft. The considered method of control has not been used so far in power plant's drive systems. The advantages of using a controlled hydrodynamic clutch is simple structure, high durability and low weight of the entire drive system. The equations of the mathematical model for the drive system are formulated on the basis of: the balance of torques and the equations of the hydrodynamic clutch with retractable rotors. The equations are based on the one-dimensional flow of the working fluid along the mean line of the stream. The model calculations are conducted numerically. In order to be able to determine the coefficients of the mathematical model, experimental research is conducted on a test bench designed specifically for this purpose. The research determines how the rotation direction and size of the gap between rotors influences the torque transferred by the hydrodynamic clutch, for selected values of the clutch’s filling degree and the working fluid’s temperature. On the basis of the model calculations results it was determined that a hydrodynamic clutch controlled by increasing the distance between rotors may be successfully used in drive systems of wind power plants to maintain a constant angular velocity of the electric generator shaft.

Opis:
The roof support, especially the ŁP yielding steel arch support, is transported and assembled in the face with the use of auxiliary machines. This activity in Polish underground mines causes numerous problems, which until present have not been solved. Currently, transport and assembly are carried out manually, while the roadheader and suspended rail are used only to a small extent. Therefore, the modular installation and transport assembly was developed jointly by FAMA Sp. z o. o. and AGH University of Science and Technology. The solution in question enables performing a number of functions (including transport and assembly of all kinds of support arches), which are not available in currently manufactured equipment. The proposed manipulator solves numerous problems occurring during the installation of the steel arch support in an underground mining excavation and significantly improves the process of drilling galleries. This innovative solution considerably differs from the existing ones, and its greatest advantage is versatility with regard to the cross-section and equipment of the roadway, as well as a wide range of functions. In addition, it can also be used for reloading works. The modular installation and transport assembly together with a platform, a temporary mechanized roof support and a mining machine, make up a mechanizes roadheader complex, which enables continuous mining, loading and installing the permanent support in underground workings.
