In the Life Cycle Management context of complex systems there are a few “families” of products which, due to the aleatory behavior of the development and production processes, present difficulties in the management of the remaining usable life and spare parts approach. One of such “family” is represented by composite materials and products. This article proposes a methodology to improve their support...
Recent developments in the Logistic Engineering field are expanding the range of analysis for Operational Availability (Ao) from purely statistical models to include prognostic models. A necessary step in order to perform prognostic analysis is the study of system's components degradations. The degradation of a component is a case by case study, which characteristics that change significantly even...
Recent developments in the Logistic Engineering field are expanding the range of analysis for Operational Availability (Ao) from purely statistical models to include prognostic models. The prognostic method allows to obtain data on otherwise costly to test failure mechanics, while also providing information on the component degradation physics and their performance alteration. Failure in a system...
Through the concept of the “physics of failure,” this article analyzes a possible extension of the modern Logistic Support Analysis (LSA) databases such as ASD S3000L in order to support a new view of operational availability based on the categorization of stresses obtained by operational scenarios and applicable to FMMEA (Failure Mode Mechanism Effect Analysis). In order to integrate such methodologies...
A methodology to enhance the efficiency of avionic measurements through the support of the ASD S3000L database is proposed. This proposal aims to the integration of an expanded FMEA analysis, supported by the S3000L database structure, with the "in field" avionic measurements. This should lead to the reduction of the times and costs involved into failure identification and resolution and...
A measurement system able to extract the envelop of signals coming from electrical motors has been presented. The system use a tri-axial accelerometer mounted on an electrical motor used on small Unmanned Aerial Vehicles to made a vibrational analysis. The aim of this paper is to show the first part of this system based on the Envelope Analysis that, with the support of a database and a comparison...
