Solving Aviation Fuel Complexities through Hyper Spectral Imaging Presentation Transcript

  • 1. Solving Aviation Fuel Complexities through Hyper Spectral Imaging Optimizing fuel maintenance, eliminating safety hazards and assuring the highest quality 1 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  • 2. HIGHLIGHTS Solving Aviation Fuel Complexities through Hyper Spectral Imaging Contaminants in aviation fuel are a serious safety hazard and undoubtedly one of the biggest concerns for the air transportation industry This paper highlights the safety aspects of aviation fuel and its handling procedures and proposes a solution using hyper spectral imaging to rapidly and accurately detect the presence of contaminants 2 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  • 3. Introduction  Current maintenance procedures required to monitor fuel quality are manual and hence are an operational cost burden for the aircraft operators  Aircraft utilization is affected as they have to be grounded to perform these maintenance procedures; there is also a human element to the integrity of the test results  With increasing fuel costs, airlines and OEMs are looking for ways to optimize the maintenance activities without compromising on safety  There is a growing interest in biofuels and experiments are being done on blended fuels There is exponential growth in air transport and fuel is 33% of operating costs. As a perspective, Shell Aviation re-fuels one aircraft every 12 seconds across 800 airports in over 40 countries for about 7000aircrafts. 3 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  • 4. Aviation Fuel Supply Chain- A brief background Fuel costs comprise of the bulk of the operational costs for an airline. There is a large ecosystem directly or indirectly connected with aviation fuel  Distributors  Aircraft engine manufacturers who perform tests and approve type certification of their engines for a specific fuel  Shipping companies (land and waterways)  Aircraft OEMs  Third party organizations who undertake refueling operations  Airlines  Companies that build refueling vehicles, pipelines, storage systems and filtering units  Standards bodies that frame & publish quality control procedures  Companies that build laboratory instruments for quality control  Government controlled regulatory bodies such as FAA & EASA  The oil companies and their refineries REFINERY FILTER  Airports WATER SEPERATOR INTERMEDIATE STORAGE TANKS MOBILE HYDRANT DISPENSER TRANSPORT 4 AIRPORT AIPORT FUEL HYDRANT © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  • 5. Aviation Fuel Hazards Fuel quality checks are mandated and audited at every stage in distribution. However, despite this, there is a high possibility of contamination. Fuels that deviate from the standard specification can cause serious mishaps Water contamination Solid Particulate Contamination Microbial Contamination  Water can enter the system due to the water separator or filter malfunction and nonconformance in the distribution, storage and re-fueling procedures.  Can be created by corrosion on the inner walls of the aircraft’s fuel tanks (caused by excess water in the fuel).  Excess water promotes the growth of microbes that thrive at the boundary of the fuel – water interface  Solid particulates can block fuel lines, nozzles and filters or result in debris that can damage turbine blades or the engine casing  It results in acids and sludge formation that can corrode metallic parts & destroy the sealing in the aircraft’s fuel feed system  As per standards, the threshold limit for water in aviation fuel is 30ppm 5 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  • 6. Hyper Spectral Imaging – An Introduction A measurement of energy levels in a specific range of spectral bands is termed as the spectral signature of the object at that point The spectral signatures can be used to identify a particular object and elemental composition of a substance by comparing it against a reference.  Spectral information (energy level) is captured for each pixel for a specific range of wavelengths  Typically measured as hundreds of wavelengths spaced nanometers apart  The resulting data is in the form of a data cube as seen here 6 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  • 7. Solution Architecture to Detect Contaminants in Aviation Turbine Fuel The mobile hydrant dispenser is the equipment at the very end of the re-fueling chain, before the fuel enters the aircraft wing. Performing an in-line monitoring of the fuel at the dispenser while re-fueling would be the most effective solution Below is an illustration of a high-level view (representative) of an instrumentation to sample the fuel in-line, while it is being delivered to the aircraft 7 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
  • 8. Conclusion: Real-time Hyper Spectral Image Processing Dispersed water and other contaminants can be addressed by anomaly detection – classification of pixels whose spectral signature differs from the background by a threshold margin  The processing of hyper spectral images involves several stages and requires efficient and fast data acquisition to extract the pixel spectral energy distribution, implementation of signal processing algorithms for classification, matching and anomaly detection as well as computation of the results subject to thresholds, for higher accuracy and reduced probability of false alarms.  Hyper spectral imaging provides a safe mechanism to rapidly and accurately detect the presence of contaminants, while meeting the regulatory norms - thereby preventing accidents, providing longer lifecycle to the aircraft components and reducing the burden of operational cost. 8 © 2013 WIPRO LTD | WWW.WIPRO.COM | CONFIDENTIAL
