In the military domain, these developments have emphasised the need for flight instrumentation and ground control systems capable of supporting system test and training activities in operationally representative and wholly safe conditions at the ranges. This paper presents the main achievements of the PISQ Laser Test and Evaluation Range (PILASTER) research and development program. In particular, after a brief description of the PILASTER system requirements, the mathematical models and the hardware/software developed for system performance evaluation and eye-safety analysis are presented, including the novel techniques introduced for accurate measurement of laser energy and geometric characteristics in various weather conditions and operational scenarios (pointing accuracy, total energy, spot spreading, etc.). Additionally, the PILASTER subsystems hardware and software architectures are introduced, followed by a brief overview of the laboratory, ground and flight test activities performed for the PILASTER formal verification and acceptance.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132328141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The question that in fact arises in the preparation of preventive maintenance program is if it is possible to satisfy the reliability requirements compatible with the economic and safety needs of the user. The answers can only be given following a correct heuristic method. Experimental data, resulting from repetitive measurements, should only serve to build simulation models that can predict what the future will hold and then as subsequent control measurements to confirm the above-mentioned model. This is particularly useful in the planned maintenance schedule, in which you get to answer the question: \"how often\"? Fit mathematical models allow to calculate, with precision and accuracy, the convenient time at which to intervene. To do this, it is therefore necessary to understand the mechanisms that dominate the evolution of the processes (prognostics) that may lead to failures. We present two examples of applications: one concerning a railway structure and the other relative to an aircraft structure.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"245 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131239624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unsteady surface pressures were measured to understand if this information could be used to resolve for turbulence-induced perturbations and furthermore utilize this information in a turbulence mitigation system. Although pressure tapping the majority of the chord is inevitability impractical for MAV application, it was discovered that a point local Coefficient of Pressure (Cp) held high correlation to the chord-wise Cp integration and allowed for a linear relationship to be formed between the two variables. The defined relationship provided a 95% confidence for angles of attack below stall and can be used to estimate the integrated cord-wise pressure coefficient at a particular span wise location. The relationship between a single pressure tap and the integrated Cp of that chord-wise section was valid for each two different span-wise locations with similar defining equations. As one pressure tap can be used to adequately estimate the integrated Cp on a chord-wise wing section, a limited amount of pressure taps across the wings span can approximate the pressure distribution across the span and approximate flight perturbations. This paper focusses on the implementation of unsteady pressure measurement and autopilot control logics for turbulence detection and mitigation.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114768496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
