Opis:: Transport is one of the major and economically most important branches of industry that provides employment opportunities and welfare for population. However, despite beneficial aspects that come together with transport development, it is often associated with potential threat to people's health and lives. It is needless to say that road safety has a great influence on society mobility. Out of all branches of industry, wad transport is considered to be the most dangerous. Such conclusions are drawn on the basis of statistics according to which the greatest numbers of people die in road accidents. Analysing the data gathered in given period, it can be estimated that more 90 per cent of the whole number of fatalities died in road accidents. Constantly increasing amount of incoming automotive vehicles as well as outdated road injrastructure in Poland contributes to the growth of various security threats connected with road transport. Due to the facts mentioned above, it is necessary to introduce important changes that would help to modify present road infrastructure and arrangement so that they are adjusted to continuously expanding transportation demands and needs. Therefore, the following changes shall be paid additional attention: quality ofroad infrastructure. Therefore, particular attention should be paid to the changes that are to be introduced. Such steps of modification aim at road infrastructure quality enhancement, improvement of the highway code, stricter requirements of different means of transport technical condition and changes concerning country transportation policy approach. These ideas are expected to result in increased road safety.

Opis:: As far as the current rules involved in business enterprise operation process are concerned, one of the most significant characteristics is specified by the need of engaging economic criterion in all procedures involved. Thus, it is required to introduce deep and extensive analysis concerning economic aspects ofpassenger transport. First of all, it is essential to specify currently existing demand for passenger transport service and compare it in relation to the supply capabilities offered by a transport enterprise. Business advantages created by the enterprise are also necessary to be considered and analysed. The basis for transport enterprise operation should be provided with order placed by Passenger Transport Executive, subcontracting firm of a chosen line according to valid schedule including both, rush and after-rush hours. In order to avoid any possible difficulties it is very important that the hired company is informed about all factors influencing economic efficiency of the serviced bus line. As a result, subcontractor is enabledto make right decisions and eliminate potential problems. Important processes having a considerable influence on proper functioning and effectiveness of public means of transport are connected with its usage, diagnosing and making it fitness for use. Operation effectiveness aspects that are the most frequently discussed in professional literature is described as relations existing between the profits and the input. It takes form of difference or quotient of the values mentioned above. This paper presents evaluation and analysis method controlling different means of transport operation system effectiveness. Method developed with the aim of analysing and evaluating public means of transport operation effectiveness, provides managerial staff with feedback, which is helpful as far as taking right decisions, is concerned. Making proper choices has a great influence on the process and it bears the responsibility for functioning of the system in terms of reliability and cost efficacy. Certainly, the more professional service is, the more satisfied customers are. Moreover, customer demands are more likely to be met, which means that all involved procedures related with functioning of the system are carried out in the accordance with regulations and reguirements, being currently inforce.

Opis:: Transport telematics systems integrate information technology with telecommunications for their use in various transport systems. Thanks to the use of advanced technical solutions and modern telecommunications and IT systems, it is possible to implement additional innovative services. They can be used to rationalize the process of using and maintaining means of transport. Modern vehicles are equipped with telematic on-board systems. Such solutions combine various electronic devices used in the vehicle. For this purpose, bus solutions are used, thanks to which it is possible to control individual systems and devices. It is also possible to use the transmitted data to detect negative exploitation phenomena during vehicle use (e.g. glazing phenomenon, work in the upper engine rev range with too low coolant temperature, intensive work compressor of the high air pressure system being a symptom of inability of pneumatic systems). This is possible because the data being sent has a specific information resource. Thanks to this, to can be concluded about the loss of the exploitation potential of the vehicle. This approach will be used to rationalize the technical service of the vehicle fleet, with regard to profiling. Using exploitation data, received via a telematic interface from vehicles, it is possible to profile the rolling stock. It consists in distinguishing individual sets of vehicles due to certain reliability and exploitation properties. This approach allows for the specification of the rolling stock exploitation, giving the opportunity to rationalize the use and exploitation. The publication presents the author’s graph of the exploitation process taking into account the profiling of the vehicle fleet. The application of the presented approach will contribute to the improvement of the value of certain vehicle reliability and exploitation indicators.

bullets perforation
Opis:: Hagg and Sankey method assesses the functionality of containment rings, which prevent perforation of an aircraft's elements from turbine engine disc fragments after disc burst. However, the method assumption was based on studies of mechanism of destruction of ballistic shields made of among others ceramics, by small arms bullets. The hard ceramic facing of the ballistic shield blunts the projectile and breaks up the projectile's hard core used for armour piercing. As an impact result, a conoid of finely pulverized ceramic dust is formed, absorbing energy in the formation process. The dust, containing the remnants of the projectile's energy hits the backing, but is now spread over a larger area. With backings made of fibre, energy is absorbed in stretching, breaking and delamination. With backings made of ductile metal, energy is absorbed in elastic deformation. Modification of the method consisted of taking into account the stratification of the ceramic-metal composite and the occurrence of an aircraft stiffened skin, in order to better assess the effectiveness of ballistic shields. The concept of estimating the resistance was based on the described destruction mechanism, where the object of analysis is a metal containment ring with an additional ceramic protective ballistic shield. A comparison of two scenarios- with and without an additional 2 mm aluminum alloy skin was taken into account. For this particular scenario, results were sufficient for both of the two analyzed endurance criteria.

Opis:: The article presents the selected elements affecting reliability and security of the telecommunications networks, which support transport services. In terms of telecommunications security, the selected methods and mechanisms, which allow providing the required level of reliability and availability of the telecommunications networks, in the fault-free operation and emergency modes, were discussed. In the article, attention was paid to the impact of a way of operation and maintenance on security of the telecommunications networks, and also on a correlation between the telecommunications system security and the security culture within the administrative and decision-making bodies. The telecommunications networks used in transport ensure the broadly understood safe provision of data transmission services. Telecommunications networks consist of hardware and software systems, and the data transmission security depends both on hardware and software. It is a set of methods and mechanisms, which provides a high level of the system’s reliability and availability by selecting the appropriate system structure.

Opis:: The safety of transport facilities depends not only on effectiveness of the applied individual safety systems but also on their power supply systems’ proper operation (also including electromagnetic interferences). Therefore, in this paper, the authors analysed the power supply selection for the electronic safety systems applied in transport, taking into account the reliability and exploitation requirements included in the regulations and standards on these systems. The appropriate electricity supply to electric safety systems is the basis of their proper functioning. It means that the power supply, with required parameters for a given device, should be connected to individual electric receivers of electric safety systems. However, only supplying electricity to the device is not equivalent to provision of its operation continuity and the appropriate level of values of the reliability and exploitation indices. Therefore, emergency power supply systems should be used. The authors developed an algorithm of the power supply selection for electronic safety systems, including the categories of power and hazards occurring in the facility. In further considerations, it is planned to carry out further analyses taking into account other types of power supply systems, and the development of a computer programme, which constitutes an exemplification of the obtained deliberations.

Opis:: It can be assumed that at least some of the systems associated with the train traffic operation work in the “mission” mode, i.e. their availability and operational dependability are related to safe “move” of a train through the strictly defined section of the railway line, i.e. systems (devices) must operate reliably during “mission”. In the remaining time, operation of devices does not affect the safe train traffic operation. For example, it is possible to list crossing signalling systems or the GSM-R system, which along with the ETCS 2/3 system, constitutes the ERTMS system. In the article, the GSM-R system operation analysis, in terms of the above-mentioned factors, is presented. In general, it can be assumed that the GSM-R system devices (e.g. BTS base stations) should be efficient within the specific periods, i.e. during the train passing through the relevant section of the railway line. According to the authors’ calculations, it is stated that within longer periods, the selected GSM-R system devices (BTS stations) cannot be fully efficient, i.e. possible failures occurred and removed in these periods will not affect the safe train running.

Opis:: In this article, the conditions to be met by a two- and three dimensional wind tunnel tests in order to ensure their correctness are presented. First of all, they relate to the flow similarity between the real and wind tunnel conditions. This similarity enforces a wind tunnel calibration, a proper design and manufacturing of the tested models, a proper research, as well as processing of obtained test data including the usage of the wind tunnel corrections. In this work, the majority of these conditions were presented but in particular, the influence of the wind tunnel corrections on the tested models aerodynamic characteristics is consider. The two-dimensional airfoil studies and three-dimensional aircraft model balance investigation were performed in two low speed wind tunnels of a different sizes of theirs test section. The wind tunnel tests were performed in two Institute of Aviation low speed wind tunnels, namely in the wind tunnel T-1 (of the 1.5 m diameter test section) and in the wind tunnel T-3 (of the 5 m diameter test section), at the same undisturbed velocity, V∞ = 40 m/s. The comparison of the lift coefficient characteristic obtained in two different wind tunnels using the same two and three-dimensional models and same measurement techniques enabled to discuss the problem of necessity of the wind tunnel corrections usage.

Opis:: This paper presents theoretical basis for evaluation of the transport system operation quality. A general evaluation model was built, and further part of the paper is to consider the theme of damageability of the means of transport, as a reliability feature, constituting one of the most important criterion to evaluate the transport system operation. Based on the analysed references in question as well as on the results of our own research it has been found that the damages to the means of transport, being utilised within the transport systems, are a result of interaction of various forcing factors. Some number of the damages results from natural wear of the means of transport elements, which is a natural phenomenon, while the remaining damages may be caused by an inefficient repair of the previous damage. This leads to so called secondary damages to the repaired element, occurred within a short time interval, which is a proof of inappropriate organization of the repairs, poor training level of the repairing teams, limits related to pre and after repair diagnosis, which directly affects reliability of the means of transport and consequently the operation quality of the transport systems in which they are being operated and maintained. Based on the analysis of the investigation results it has been found that the primary damages are independent on one another and they occur randomly. The secondary damages are dependent, because their occurrence depends on prior occurrence of the primary damage and the effect of its improper repair or improper repair of the next secondary damage.

Opis:: Determination of possible manoeuvres to be performed by the aircraft requires knowledge of its aerodynamic characteristics including, in particular, characteristics of the aircraft at configuration with deflected control surfaces. In this article, the wind tunnel tests results of the model of passenger Tu-154M aircraft manufactured at the scale 1:40 are presented. The model was designed and manufactured by the Military University of Technology based on the Tu154M aircraft geometry obtained by full-scale object scanning. The model mapped all aircraft control surfaces, along with the gaps between these surfaces and the main wing part. During the tests all the model’s control surface like, flaps, ailerons, spoilers, slots, rudder, elevator and tail plane were deflected at the same deflection angles range as they are used in the full scale aircraft. The aerodynamic characteristics of the tested Tu-154M aircraft model were measured by the 6-component internal balance. Based on the obtained measurements the aircraft model aerodynamic coefficients were calculated. In the article the basic aerodynamic characteristics of the tested Tu-154M aircraft model i.e. lift, drag coefficients as well as pitching, yawing and rolling moment coefficients versus model angles of attack and sideslip angles were presented. The tests were performed in the Institute of Aviation low speed wind tunnels T-1 of the 1.5 m diameter test section at the undisturbed velocity, V∞ = 40 m/s

Opis:: This paper presents a framework for the reliability characteristics estimation on the experimental data. The framework consists of the set of failures, the experimental data sources, the set of reliability characteristics, the estimation methods, the estimation goodness tests and the expert system supporting estimation and statistical inference processes. The experimental data was obtained with two main theoretical means: control theory and diagnostics. It has been observed that changes of the functioning condition potential could serve to determine the symptoms of transient (momentary) failures and the changes in the potential of the technical condition to determine the symptoms of parametric faults. Such an information is sufficient to calculate reliability characteristics before dangerous catastrophic failures occur and to calculate reliability characteristics for single object without having to deal with a numerous set of objects. The set of reliability characteristics models consists of the analysed failures combination and distribution functions used in the reliability engineering. The set of estimation methods includes analytical and numerical ones. The proposed expert system supporting estimation and statistical inference processes consists of data base (the experimental data), rule base and inferring machine.

Opis:: This paper presents a development of the known qualitative method for assessment of engine operation, applied to ship main diesel engine as an example. According to this interpretation engine operation can be presented as a physical quantity. In this aspect, based on the selected functional system of the engine, was assessed usefulness of the quantity for description reliability features of the system. To the analysis was applied Poisson's uniform process which made it possible to elaborate a model of run of worsening the considered system's operation taken as a random process of identical independent decreases of energy efficiency within a given time interval. The presented method is a valuable supplement for description reliability features of ship main engine what is important for realization of shipping tasks by sea. Additional advantage is versatility which makes that it can be applied to reliability analysis of any ship device or ship energy subsystem. Classification of the engine serviceability states with taking into account the assessment of its operation in energy-time aspect, schematic diagram of lubricating system of RTA48-TB engine and values of lubricating oil parameters in steady conditions for the engine load, graphical presentation of lubricating oil cooler operation graphical interpretation of the decreasing of oil cooler efficiency are presented in the paper

Opis:: The presented paper concerns with the technical object reliability evaluation based on the parametric and momentary failures during the process of object operating. The real world data observation shows that in the case of high quality technical objects the catastrophic failure events are too rare to the credible evaluation of the object’s reliability. For that reason, the parametric and momentary failures are in the centre of attention in this paper. The set of analysed failures was obtained with the classifiers of the field data provided by the monitoring system (the failure alarms) and the diagnostic system (the functional and technical condition parameters deviation). The changes of the functioning condition potential are used to determine the symptoms of momentary failures and the changes in the potential of the technical condition to determine the symptoms of parametric failures (non-total). The assumed reliability characteristics model has the form R(t) = f(_, Rb(t), Rc(t)), (where: Rb(t) and Rc(t) – the estimators of reliability for parametric and momentary failures, symbol ‘_’ denotes catastrophic failures not covered). For the identification of R (t) as an analytical function, the estimators are computed with the field data. The Weibull distribution function due to its flexibility is often used. Such is the case in this paper. Two parameters a and b known as the scale and the shape parameters are estimated with the computerized procedure realizing least-square method. The presented examples show good fit quality even for small set of data.

Opis:: Testing and reasoning are two main closely related diagnostic activities. Diagnostic testing is realized in Newtonian (short) time while diagnostic reasoning - in (long) Bergsonian time. Both sort of time are used to analyze different kinds of problems in diagnostics and reliability of technical objects. Newtonian and Bersonian time differentiation needs some expert knowledge. In this paper, considerations are based on observation that Newtonian time of diagnostic testing is related to object maintenance (adjustment) and Bergsonian time is related to object is reliability. A significant change of the object’s technical condition (signals or parameters of the state) causes changes of its regulation state (quality indicators change) and the characteristics of reliability. As it is required for the operation and reliability to be always appropriate and permanent, the control should be adjusted to functional needs of the object, and the use should be adapted to the current characteristics of reliability. Therefore, change of the settings of the control device (made during the handling of the object) represents the change of technical condition and state of reliability. It is presumed that, during the operation of a technical object, the selection of the control settings for damaged object is impossible. This fact, when predicted, becomes the basis for the prediction of the object reliability.

Opis:: The quality of the tests results is of paramount importance in the process of assessing conformity, conducted among the others, on the safety of the products use, their functionality or type approval. Ensuring the reliability of the results and their consistency should be an absolute priority in the operation of all appointed for this purpose metrology institutions and organizations, especially those units whose product offered to the customer are goods and services are based on measurements and their results. The essential criterion for assessing the quality of the results is their reliability to the user. One of the major issues that have a significant impact on the reliability of tests results is a form of reporting the results to the client. This paper addresses the key issues related to the presentation of the tests results. Discussed are the risks associated with the presentation of test results. The qualities that the measurement result should have to be reliable to the customer, have been identified. The significance of the accreditation for the validity of the results has been presented. Normative documents containing the requirements for the presentation of research results have been recalled. The information to be contained in a report from an accredited testing laboratory provided to a customer has been specified. The principles of the identification of the document describing the test methods have been discussed. Attention was drawn to the need for placing, in the report, the information about the uncertainty of the measurements. The principles of placing in the test report and the assessment of conformity as well as the opinions and interpretations, have been discussed. The detailed requirements for use, by research laboratories, the accreditation symbols in test reports have been presented
