Perform an analysis at system level using FTA and FMECA to assess failure of the IGB. This should consider the reliability at the point of dispatch as well as
in flight.
Discussion of system reliability issues and recommendations for changes to design or maintenance tasks in relation to FTA and FMECA Analysis.
Task 2
Your analysis should now be expanded to include the reliability of the Main gearbox lubrication system. Figure 3 shows a Reliability Block Diagram for Loss of
Oil Pressure. This should be integrated into your analysis for the transmission system. Although the analysis should focus on the IGB and Main Gearboxes,
you should consider the effect of reliability on aircraft safety as a whole. For any critical items, you should suggest possible maintenance actions, either
preventative or corrective, and/or any condition monitoring for dormant faults. You will need to justify your analysis with your own research and good
engineering judgment. However, there is no need to develop any aircraft diagrams.
Also discuss the system reliability issues and recommendations for changes to design or maintenance tasks.
Sample Solution
Fault Tree Analysis (FTA) is a system reliability assessment method which can be used to analyze the failure of the Integrated Guided Bomb (IGB). The analysis involves looking at a series of events and conditions in order to determine how they may have contributed to a particular mishap. This type of analysis allows engineers an improved understanding of which parts, processes, or tasks led up to the failure – allowing them greater insight into potential solutions for preventing similar issues from occurring in future designs.
For instance when considering IGB’s dispatch reliability FTA looks at factors such as environmental elements (temperature/weather), human errors like incorrect readings or mishandling of equipment, mechanical components that may not be functioning correctly etc., – all coming together to form a tree-like diagram containing multiple branches based upon each component or factor involved. By examining this diagram one can identify which points were weak links leading up to an incident; giving engineers insight into where improvements must be made in order for similar events from taking place again.
FMECA (Failure Modes Effects and Criticality Analysis) is another tool that can used help assess reliability issues within systems. Similar FTA it looks at various element & processes related to IGB’s performance both on dispatch as well during flight; however FMECA goes further by including actual effects under consideration– enabling evaluators better understand severity level associated with certain failures as well their likelihood occurrence when analyzing data collected over time. Such information can then be used adjust design parameters accordingly so as increase system robustness while also recommending changes maintenance procedures if necessary.
In conclusion then we can see how both FTA & FMECA are essential tools for assessing system reliability with regards to IGB’s – providing engineers deeper insights into what went wrong along with recommendations regarding any necessary changes needed ensure such issues do not arise again! on vacation, I decided to stay home.” Here the dash emphasizes the sudden and unexpected change of plans which was just mentioned.
