Reliable measurements of the air velocity flowing around the wings of the aircraft and the altitude at which the aircraft is located are necessary for controlling the unmanned aircraft. Due to the need to use automatic flight stabilization processes, unmanned aircraft require a minimal delay in the measuring path. For correct measurement of these quantities, a system based on two measuring lines using backflow tubes was built. This article describes the effects of a research project carried out by the Student Scientific Group of Electronics at the Rzeszów University of Technology, who were seeking a reliable and quick solution with increased accuracy.

Nowadays, we spend most of our time inside buildings. Thus, ensuring adequate thermal comfort is an important issue. The paper discusses the issue of thermal comfort assessment in the intelligent low energy building “Energis” of Kielce University of Technology (Poland). The tests conducted in a selected lecture theater focused on collecting anonymous questionnaires containing thermal sensation and air quality votes of the respondents as well as performing measurements of indoor air parameters (air and globe temperatures, relative humidity, air velocity and CO2 concentration). Based on the obtained data a comparison has been done between the actual sensation votes of the volunteers and the calculation results performed with the Fanger thermal comfort model. Two indices have been considered in the paper: PMV (Predicted Mean Vote) and PPD (Predicted Percentage Dissatisfied). A modification of the model has also been proposed, which considers the impact of the carbon dioxide concentration on thermal comfort.

The article describes the vibration measurement technology used in experimental investigation of light aircraft and some series of exemplary results obtained during the prototyping process. The aim of investigations presented herein was to determine the resonant frequencies and natural modes of an aircraft or its selected structural components. Ground vibration testing is an essential dynamic structural test necessary to carry out before the aircraft certification. This test should be performed on the aircraft example which is predicted to be tested in flight. The measuring system used for ground vibration testing in the Institute of Aviation Technology of the Military University of Technology consists of a multi-channel LMS SCADAS analyzer, a set of piezoelectric accelerometers, two vibration exciters equipped with impedance heads and a computer with the Test.Lab Software. The aim of the article was to present the methodology of performing ground vibration testing tests. Having applied the equipment to measure an airplane or its airframe component, key vibration characteristics corresponding to specific resonant points can be determined. Not only completed aircraft can be tested but also its isolated fragments (wings, stabilizers, tail units) or just empty airframe. Testing separately supported components allows examining their aeroelastic properties at early stage of prototyping. Ground vibration testing technology applied in various stages of the prototyping process was demonstrated in four peculiar research cases. The testing examples presented herein were the following: the isolated strut-braced wing of a light reconnaissance airplane, the light drone imitating an aerial target for some on-ground anti-aircraft artillery sets, the empty airframe of a very light jet and the miniature UAV. Some exemplary results obtained from testing these objects were presented. At the end, some observations and conclusions were noted in the context of usefulness of conducted researches.

This study explores the utility of a transdisciplinary research project framework for improving sustainability awareness levels within a University of Technology. The quest to make contributions to the attainment of society’s sustainability aspirations has seen universities transforming into living ‘real world’ laboratories. Yet, low levels of sustainability awareness among different stakeholders pose a challenge towards institutional transformation. A transdisciplinary research project is proposed as a panacea. Adopting a narrative analysis research design, this study reports on the reflections of different stakeholders concerning the utility of the project and its underpinning framework for the creation of requisite knowledge for efficient building energy management (BEM) and building management (BM) systems -an integral aspect of the research project- directly engenders improved levels of sustainability literacy. Preliminary findings from these reflections indicate the utility of the framework for improving sustainability awareness among stakeholders: academia, support and management staff. Subsequent studies will further reiterate this finding whilst providing a robust methodology for executing similar projects in identical contexts. This paper’s originality lies in the use of transdisciplinary research projects to improve sustainability awareness levels across university environments within South Africa

There are different phases in which attempts can be made to prevent an emergency situation from happening or to fight its consequences when it does occur. These phases describe all activities that are aimed at increasing safety and can be represented schematically. This representation is called the safety chain. This paper looks at the phases of the safety chain where human behavior in evacuation can be influenced to mitigate the outcomes of an occurring emergency situation. A literature research has been done and the problems with human behavior are identified. Possibilities for further research are given, as well as the contours of a research project that will be carried out by the end of this year at Delft University of Technology.

Eli Ltd. and Tallinn University of Technology (TUT) Department of Mechatronics are currently performing studies in order to develop a mini-class universal purpose unmanned aircraft [1,2]. The paper focuses on strength calculations and weight vs. strength optimization of the fuselage of this developed UAV system. To develop a strong but lightweight UAV fuselage, advanced computer modeling and finite element structure analysis are used as virtual prototyping tools for the optimization of the fuselage at early design stage and through the production period to improve the design [3]. Design optimization is applied to minimize the maximum stresses within the fuselage, subject to strain constraint in conjunction with both geometry and choice of appropriate fibre orientations and stacking sequence as design variables and also material parameters. The fuselage for the UAV plane was designed and manufactured using E-Glass/Epoxy and High modulus (HM) carbon/Epoxy composites. In this paper ANSYS software has been successfully applied to minimize the weight of the fuselage and increase the UAV fuselage strength. The results show how the fuselage design could be improved with the help of finite element method analysis and provide guidelines for the structure and material design for the composite based UAV SWAN fuselage.

Considering the exponential growth of drone technology and its expected economic effect [1], the Hungarian Government called on the industrial and academic sectors for an innovative cooperation in the field of intelligent autonomous mobility. The tender was launched by the Institute of Transport Sciences Non-profit Ltd. (ITS) last December, and among the winners was the joint tender of the Mould Tech Systems Ltd., the Budapest University of Technology and Economics and the University of Public Service (UPS). The common research is focusing on the implementation of a special Vertical Take-Off and Landing Unmanned Aircraft System (VTOL UAS)-based meteorological support system which is to measure the lower parts of the atmosphere within the planetary boundary layer (PBL). The researchers of UPS are examining the legal issues of operational conditions, flight authorization, flight safety aspects concerning the identification of potential dangers, and the airworthiness issues and will formulate their recommendations. In this paper the authors introduce the numbers of issues that have to be solved in favour of the safe and legal VTOL UAS operation.
