This method was previously applied to a simple rotating machine test rig with basic functions that are common to a rotorcraft. Using the technique proposed in this paper, designers can examine the basic functions, and select appropriate analyses to eliminate or design out the potential failure modes. In turn, the failure modes are then linked to the basic functions that are carried within the components of the aircraft. In this work, this is accomplished by mapping failure modes to certain components, which are described by their functionality. The aircraft design needs to be passed through a general technique to ensure that every potential failure mode is considered, while avoiding spending time on improbable failure modes. The majority of techniques use prior knowledge and experience as well as Failure Modes and Effects as methods to determine potential failure modes of aircraft. Eliminating or reducing performance and safety problems can be achieved with a thorough understanding of potential failure modes in the design that lead to these problems. Performance and safety are the top concerns of high-risk aerospace applications at NASA. In one failure, the cause was determined to be impact during a crash the features of impact fracture were distinguished from overload fractures by direct comparisons of the received specimens with laboratory-generated failures.ĭeriving Function- failure Similarity Information for Failure-free Rotorcraft Component Design Some of these causes could be eliminated in future components by better process control.

In five failures the crack propagation was by fatigue, though in each case the fatigue crack initiated from a different cause. The presence of corrosion products and of chemically attacked or mechanically rubbed areas here hindered precise determination of the cause of crack initiation, which was then indirectly inferred from the scanning electron fractography results. Identification of fracture surface features from fatigue and overload modes was straightforward, though the specimens were not always in a clean, smear-free condition most suitable for failure analysis. The results shows that PCA method is capable to detect the occurrence of a failure at any sensor.įailure analysis of aluminum alloy componentsĪnalysis of six service failures in aluminum alloy components which failed in aerospace applications is reported. The method used is Principal Component Analysis (PCA) to reduce the dimension of the sensor, with the Squarred Prediction Error (SPE) and statistic Hotteling criteria for detecting sensor failure indication. In this research, a sensor failure detection method for FASSIP system is developed, so the indication of sensor failures can be detected early. The accuracy of sensor measurement of FASSIP system is essential, because as the basis for determining the characteristics of a passive cooling system. The FASSIP system (Passive System Simulation Facility) is an installation used to study the characteristics of passive cooling systems at nuclear power plants. Thus researches on passive cooling system for Nuclear Power Plant are performed to improve the safety aspects of nuclear reactors.

In the nuclear reactor accident of Fukushima Daiichi in Japan, the damages of core and pressure vessel were caused by the failure of its active cooling system (diesel generator was inundated by tsunami). Sudarno Juarsa, Mulya Santosa, Kussigit Deswandri Sunaryo, Geni Rina Sensor Failure Detection of FASSIP System using Principal Component Analysis The failures discussed are (1) intergranular stress- corrosion cracking of core spray injection piping in a boiling water reactor, (2) failure of canopy seal welds in adapter tube assemblies in the control rod drive head of a pressurized water reactor, (3) thermal fatigue of a recirculation pump shaft in a boiling water reactor, and (4) failure of pump seal wear rings by nickel leaching in a boiling water reactor.

Analyses of four failed components from nuclear plants are then described to illustrate the kinds of failures seen in serv-ice. The considerations involved in working with and analyzing radioactive compo-nents are reviewed here, and the decontamination of these components is discussed. Analysis of failed nuclear plant componentsĪrgonne National Laboratory has conducted analyses of failed components from nuclear power- gener-ating stations since 1974.
