Analysis of Causes Damage in Flight Compartment Windows Due to Heating System Failure in Boeing 737-800 Airport Using Weibull Analysis Distribution

An aircraft is a means of transportation used to transport people or cargo from one place to another with a shorter travel time than using land and sea transportation modes. The relatively short travel time and affordable ticket prices make this mode of transportation increasingly desirable by people who want to travel from one place to another with the distance to many days if using land and sea transportation modes.The window on the airplane was installed in order to enable the crew (captain and first officer) to see the conditions outside the aircraft that support the aircraft control process. Windows must be designed as strong and lightweight as the window in the cabin. Windows must withstand the pressure generated by the pressurized cabin. The pressurized cabin is very important for aircraft flying at altitudes of more than 10,000 feet because it will affect the comfort of passengers during the flight. Additional requirements that must be possessed by the windows are that they must be able to provide clear vision to pilots in certain natural conditions such as rain, must be able to be opened so that it can be a way out for the crew during an emergency, and be able to withstand bird strikes so that flight safety and security can reached.From the results of the calculation of the analysis by the method of Weibull Flight Compartment Windows components on Boeing 737-800 aircraft, it is known that the best maintenance effectiveness for Windows Flight Compartment components is gradual degradation with a value (β)> 1,0 (1,305) is a type of wear out (wear out). While the resulting b value is 0.766. In accordance with the provisions that for b = 0,1 (probability 0,1%) is categorized as a serious failure, so special attention needs to be paid to the Flight Compartment Windows component.

The reasons for selecting wooden ships are a variety of time and trip frequency, whereas the reason for selecting ferries is the cost.

Study of Maritime - Road Intermodality in Constanta Port by Evaluating Trips Generation/Attraction Potentials

The changes increasingly accentuated in recent years in the global economy, in the context of globalization, have created an environment in which transport sector must adapt continuously. This adaptation process acts especially at intercontinental level, involving that transport and distribution of goods and raw materials on long distances to be as efficient in terms of duration and costs of transport and, at the same time, with reduced negative implications on the environment. The achievement of transport processes, in equilibrium conditions between demand and supply, in relation to limitations mentioned above, is possible by promoting intermodal transport, which requires a very good connection between continental modes (road and rail transport) and shipping. According to European Commission, about 90% of total import / export trades at the level of European Union are done by maritime transport. This paper aims at identifying potentials of generation / attraction of travels made on road transport at the level of intermodal node represented by seaport of Constanta. These trips generation / attraction potentials may be further used as input data in dimensioning processes of intermodal logistics facilities (handling, storage and internal transport) between road and sea transport modes. In the frame of the study are processed and analyzed data obtained through origin - destination surveys conducted during general traffic census carried out in 2010, on the network of European, national and county roads of Romania. Also, were processed data regarding types and volumes of goods transited through this port in the period 2005-2010, and the types of ships used to load these goods. Statistically analyzing these two types of data, it was revealed that grain represents 34% and petroleum products 57% of all goods (in terms of weight) handled in the seaport of Constanta, and also that the continental transport mode predominantly used to move these categories of goods is road transport. The results of performed analyzes, that describe the current situation regarding the trade flows in the port unit, constitute the starting point in traffic modeling for the purpose of freight transport planning at future time moments. Models for traffic estimation in ports take into account the predictions about economic development in influence area on short, medium and long terms.

고속 및 고효율의 해양 수송수단에 대한 필요성이 점차 증가되면서 위그선(WIG: Wing in Ground effect)이 차세대 수송수단으로 관심이 집중되고 있다. 이러한 고속 해양 수송선의 구조설계 시 수면에 대한 충격하중은 중요하게 고려되어야 할 하중요소 중의 하나이며 착수하중에 의한 동적거동은 손상을 초래하는 중요한 요소이다. 본 연구에서는 위그선 착수 시 수면 충격하중에 대한 수치해석을 통해 선체의 동적거동을 평가하였다. 착수환경에서의 수면충격하중을 ALE (Arbitrary Lagrangian-Eulerian) 유한요소법을 적용하여 해석을 수행하였으며 3차원 쉘요소를 적용한 전기체 모델을 개발하여 위그선의 착수환경에서 선체의 동적거동을 모사하였다. 착수환경은 정상 착수조건과 측풍에 의한 비정상 착수조건 두 가지를 고려하여 해석을 수행하였으며 이러한 착수환경이 위그선 구조의 정적 구조 안정성에 미치는 영향을 평가하였다 Demand for high speed sea transportation modes has been increased dramatically last few decades. The WIG(Wing-in-ground effect) is considered as next generation maritime transportation system. In the structural design of high speed marine vessels, an estimation of water impact loads is essential. The dynamic structural responses of the WIG excited by the water impact loads may bring an important contribution to their damage process. The work presented in this paper is focused on the numerical simulation of the water impact on the WIG craft when it lands. It is aimed to study the structural responses of the WIG craft subjected to the water impact loads. The Arbitrary Lagrangian-Eulerian (ALE) finite element method is used to simulate the water impact of the WIG craft during a landing phase. A full 3D shell element is used to model the WIG craft in carbon composites, and a developed FE model is used to investigate the effect of the water impact loads on the structural responses of the WIG craft. In the analysis, two different landing scenarios are considered and their effects on the structural responses are investigated.
