Opis:: The main purpose of this article is to present the structure of a tactical air force, on the example of the Polish Tactical Air Force, in a form of a technical system. This kind of technical system presents the technical point of view and organizationally bonds currently existing systems, objects (facilities) and components that are included into the Polish Tactical Air Force. The authors consider the Polish Tactical Air Force as the main analyses domain of this article. The model of presented system is mainly focused on operators’ organization and operation system of military aircraft, which are considered as technical objects (facilities) in a tactical air force. At the beginning of this article, the Polish Tactical Air Force is placed in more complex systemic structures. Then, the authors use the systems methodology, systems engineering, technical object-oriented (facility-oriented) approach and the matrix of the Model of Generalized Technical System to describe the Tactical Air Force System and present it via the model of such a system. The following model is based on a tree-shaped scheme divided into five levels of decomposition. The Model of Tactical Air Force System (as the “final product” of authors’ considerations over the selected analyses domain) has a considerable contribution to systems’ development in the Polish Armed Forces. The above-mentioned systems’ development could lead to greater progress in the Polish military as well as in systemic ideas. The implementation of the systems methodology in the design process of a new system, performed in a tactical air force, is an example of technical object systems engineering.

Opis:: In this paper the possibilities of providing fresh water for sailing vessels based on the example of s/v Dar Modziey are presented. Different methods of obtaining fresh water such as rainwater harvesting, replenishing water tanks at harbours, collecting condensed water from air conditioning systems or producing fresh water from seawater by means of desalination equipment were considered. Vacuum vaporizers (heated by fresh water used as a cooling medium of the main propulsion engines) and osmotic desalinators (using the phenomenon of reverse osmosis) were being taken under consideration. Special focus was put on the quality of water obtained; comparing the methods mentioned and pursuing the best solution both in technical and economic terms. The choice of desalinators was preceded by the analysis of quantity and configuration of pumps and membranes that will guarantee optimum performance. Selection of the manufacturer was determined by costs of purchase, costs of operation and the availability of spare parts and consumables. The osmotic desalinator ended up as the final choice of fresh water producing device on s/v Dar Modziey. Excessive water consumption can be satisfied by replenishing supplies at ports. The paper is concluded with comments and suggestions that can be adapted by a ship owner as a solution for the problem of supplying vessels with fresh water.

Opis:: The development of an engine air filter is based on filter performance requirements, vehicle 's operational environment, available space, filter media properties, and production technology. The design process includes analyses of theoretical and empirical models describing filter media performance and aerosol flow in filter housings and through filter elements. Filter media are carefully selected based upon these models and simplified laboratory tests. The filter element design is evaluated in great detail through a series of laboratory and field experiments. The role of the engine air induction system has increased because of recent engine exhaust particulate and evaporative emission regulations. Engine lifetime, engine emission and fuel consumption depend on the air induction system design and its performance. Providing optimized solutions for these requirements dictates filter development trends. This drives the need for smaller, more compact filters and more efficient filter media with higher permeability. The efficiency can be drastically improved by applying a layer of nanofibers to a cellulose or synthetic substrate. The ISO fractional efficiency test method, that in its final stage of development, can clearly show the advantage of nanofiber filter media. This paper discusses air cleaner design including the newest in-line reduced volume air cleaners and the role of nanofiber filter media in engine air filtration.

Opis:: A scheme has been developed to be utilized for solving the interaction between wing aerodynamic loads and the flexibility of wing structures under a quasi static assumption. The interaction is implemented through a link between the nodes of finite element model and the grids of transonic small disturbance model. The particular finite element responses, namely translational displacement vectors (TDV), are utilised for reconstructing the deflected wing surfaces. So in each iteration, the updated surfaces are involved as the parent for regenerating the TSD grids. The criteria of the Euclidean norm is applied for evaluating the convergency of aero-structure interaction. Catia-V5, is fully employed to manage three dimensional geometries for developing the model of wing structures, calculating grids and aerodynamic loads, as well as for reconstructing the updated wing surfaces. Numerous functions and objects of Catia are employed by conducting particular accesses via component object models using Microsoft Visual Basic.Net. A case study is excersized to demonstrate the interaction in transonic speed. The results shown that the scheme is very good in the way performing the interaction in quasi static condition. The utilization of TDV for generating the deflected wing surfaces indicates the capability of high fidelity deformations with respect to the complexity of finite element model

Opis:: This paper presents an overview of the most important requirements and recommendations of international organizations for the area of LNG terminal under construction in Świnoujście. These recommendations should be considered when planning safe traffic and manoeuvring of ships in port approaches to the Port of Świnoujście and to the Outer Port of Świnoujście. The approach area to the new terminal is located on shallow waters. Up to the present moment the fairway, anchorages and seamarks have been used by vessels of smaller size. After the construction of the new port with an LNG terminal it will handle the greatest LNG carriers. To ensure their safe entrance to the port, the fairway should be prepared with sufficient width and depth, with navigational aids. It is also necessary to prepare appropriate emergency anchorages and places where the vessels can return in case further voyage is dangerous. Additionally LNG cargo is very dangerous, because of this there is a compulsory to introduce of the highest safety standards, both in the design of the approach area and the application procedures for ships traffic. In particular, fairways and port canals, Under Keel Allowance, air draft, turning basin, vessel traffic services (VTS), traffic separation schemes (TSS), moving safety zone, and required speed limit are presented in the paper.
