Reliability analysis of the

The main goal in dependability work is to estimate the percentage of units a product that will still be functioning after particular period time. In order able make such statement, it necessary select probability distribution facilitate construction reasonably precise statements type one wishes make. this analysis, number hours between failures has been used as variable for reaching conclusion about aircraft. It was concluded can described log-normal distribution.

The aim of this paper is to analyse the situation aviation and air traffic in European Union present relation between number passengers counties on Old Continent, which will make it possible observe relationship identify causes changes. average growth rate also presented contribution. Such an analysis may be helpful preparing airports for increasing future. A statistical selected aspects enable reveal related transport Europe predictions might visualise expectations following years. In...

In the era of globalization and permanent travel people between far away regions world, air transport is one most important means transport. Today it also secure modes possibilities. Despite this, crucial to continuously improve level safety reduce absolute number accidents their victims. This idea stands at beginning article subject creation same time an attempt further safety. The pilots passengers plays a role during operations. One factors reliability aircraft. main goal in work estimate...

The aim of this paper is to find a trend in air transport behaviour the Czech Republic and Poland, based on data collected between years 2004 2016. choice period for analysis was made because date when both mentioned countries joined European Union availability data. used article provided from Eurostat web page where many revealing statistics are collected. correlations indicators were chosen as method analysis. It observed that number passengers increased up 30% 460%, respectively, Poland....

Hagg & Sankey method assesses the functionality of containment rings, which prevent perforation an aircraft's elements from turbine engine disc fragments after burst. However, assumption was based on studies mechanism destruction ballistic shields made among others ceramics, by small arms bullets. The hard ceramic facing shield blunts projectile and breaks up projectile's core used for armour piercing. As impact result, a conoid finely pulverized dust is formed, absorbing energy in formation...

Structural health monitoring of aircraft is a necessary topic especially with aging fleets. In general, it means tracking the structural integrity and keeping risk not detecting hazardous cracks low. Traditionally fatigue analyses from collected data have been carried out in flight-by-flight basis. However, simultaneous good-quality recordings most relevant flight parameters calculated damage synchronized enable more thorough analysis. Using an adequate collection time stamped parameter...

In most NATO countries, helicopter pilots are prepared in accordance with a modern system of threestage training: selection, basic and advanced. The training the air is performed according to parallelism training. scheduling pilot process based on parallel model, which includes technological relationships between individual exercises, whereby for each exercise, exercises specified, must be done beforehand. purpose this contribution propose multi-criteria mathematical model would enable...

This paper will present a comparison of the two satellite systems: GPS and GLONASS. The data their exploitation be taken into account. Both systems booster stations were specified. research on has been presented. Experimental studies as well statistical analysis collected presented successively in order to identify positive or negative forecasts for development

In the time of globalization and continuous travelling people between different parts world, air transportation is becoming one most important modes transport. Nevertheless, it crucial to continuously improve level safety reduce absolute number accidents their victims. The risk analysis with usage IT system TURAWA, which was developed collect aircraft’s informations, has been discussed in presented article. Calculation based on data sample collected operation process. implementation...

This contribution intends to present procedures for Single Flight Probability of Failure calculations. Described mathematical models were the basis creation original software Aircraft Structural Reliability Assessment (AStRAss), that allows comprehensive reliability calculations point aircraft structure under real operating conditions. The theme paper is sensitivity failure rate input data, such as initial crack size distribution, stress intensity factor, stress, and growth curve.

Abstract Knowledge about loads occurring in the structure during aircraft operation is vital from point of view damage tolerance approach to design. In best-life scenario, such information could be available a network sensors, e.g. strain gauges, installed measure local stresses. However, operational monitoring (OLM) systems are still not widely applied. Instead, what set flight parameters, which by laws inertia and aerodynamics help determine dominant part acting on given element. This...

Abstract Exploitation of aircraft can be associated with risk sustaining air accidents. The reduction is possible as a result an analysis, portraying the most dangerous incidents and undesired events. In this paper reliability based on events that occurred during current exploitation trainers variant PZL-130 Orlik TC-I TC-II was determined. From among all events, ones characterized by greatest likelihood occurrence were selected. probability average time to event calculated. Then, graph...
