Aircraft Fuel System Calibration & Verification Course

Rod Van Dyk (SAWE Fellow, Safran Landing SystemsMomentum 3

Mass Properties Engineers are often requested to either participate in or generate a fuel system calibration and verification process for new aircraft in development or for aircraft whose fuel systems have been modified, since it involves having the aircraft supported on scales. This course gives all the pertinent steps to ensure that this process is completed in a safe, successful, and timely manner.
This four hour class outlines the basic fuel usage process; including how fuel quantities are measured, fuel system calibration techniques, understanding terminology such as usable and unusable fuel, and all aspects of fuel usage that can be determined on the ground. Some hands-on non-fl ammable liquid density measurements representative of fuel density measurements will also be part of the class.

The Hampton Roads Chapter of the Society of Allied Weight Engineers is proud to introduce Ms. Dawn Schaible, Director of Engineering at the NASA Langley Research
Center, as our opening session speaker. Ms. Schaible will share highlights from the center’s past and present while discussing its bright future. Along the way she will share with us her personal experiences in the art and science of systems engineering and its role in mission success.
Langley is entering its second century of innovation and discovery. From biplanes to hypersonics and space exploration, the center has contributed to innumerable
aerospace engineering achievements since its founding as a National Advisory Committee on Aeronautics (NACA) test center in 1917. Today, Langley strives to continue that legacy with ongoing work on such programs as:

  • Space exploration, for robotic and manned missions, architecture and vehicle
    definition
  • Entry descent landing systems to enable robotic and human space exploration missions
  • Future air transportation - environmentally responsible aircraft, urban air transportation, personal air mobility, high speed air systems
  • Understanding our Earth environment as a system, air and space based measurement systems

Speaker: Dawn Schaible, Director of Engineering NASA Langley Research Center, Hampton VA Prior to her current position Ms. Schaible served as NASA’s Deputy Chief Engineer, where she led the implementation of the Chief Engineer’s role in Agency Technical Capability. She was the region’s “Peninsula Engineer of the Year” in 2012, nominated by the Hampton Roads Area Chapter of the International Council on Systems Engineering (INCOSE). She has also been Manager of Systems Engineering for the NASA Engineering and Safety Center (NESC), providing systems engineering expertise to independent safety assessments of critical, high-risk issues. Prior to transferring to Langley in 2005, Ms. Schaible spent 18 years at NASA’s Kennedy Space Center where she held lead engineering positions for the Space Shuttle and International Space Station Programs. She has a M.S. degree in Engineering and Management from MIT, as well as an additional M.S. in Space Systems Operations from the Florida Institute of Technology, and had began her career with a Mechanical Engineering degree from Bradley University.

10:00 Paper 3729 Application of the Basic Parametric Methods

Doug Fisher (Manager, Engineering ACE Team & Weight – Aerostructures COLLINS AEROSPACE)

Abstract

This paper details how the learning contained in SAWE course “Developing Basic Parametric Methods” was applied at Collins Aerospace for estimating nacelle weights of new commercial and business jet aircraft. Collins has decades of experience developing nacelles and a large database of historical weight data, but has not effectively leveraged that data into better weight estimating tools. Learning from this course was applied to develop improved methods of estimating the weight of nacelles for new product proposals. This has allowed us to not only provide better weight estimates but also better understand the limits of our data and estimating methods.

10:30 Paper 3719 Lightship Evolution Diagnostics with In-Service Stability Measurements

Colin MacFarlane and Manuela Bucci (Tymor Marine, Ltd)

Abstract:
Lightship mass and center of gravity are the basis for assessing ship regulatory stability and the maximum payload that the ship can load results from this assessment. Knowing the ship mass and centre of gravity is therefore of utmost importance for both commercial and safety reasons.
It is known that, over time, both these quantity change. At present, changes in the lightship are addressed by five-yearly audits that may lead to an inclining experiment - the traditional way to measure ship mass and centre of gravity. The time gaps are filled with estimates based on weight control which can be shown to be a ‘random walk’ process. This means that, temporarily, undetected worsening of the ship stability might occur.
Draught measurement provides immediate feedback of the accuracy of the estimate of weight change, provided draught sensors are adequately maintained. Evidence of change in the vertical position of the lightship center of gravity is not, however, obvious.
In-service stability measurements, integrated into the vessel’s operational routine, directly estimate the vessel VCG and can diagnose changes in the lightship vertical moment using statistical process control techniques. Changes in the progression of mean values of Deadweight and Lightship vertical moment are used instead of records of weight changes to build a model of ship stability over time with uncertainty on the mean value decreasing with increasing number of measurements. Weight control remains important to characterize the changes and discrepancies from the loading program can be used to identify sensor failures, defective estimates of cargo deadweight and Lightship changes.
This paper briefly reviews conventional techniques (referring to previous Conference papers). It then discusses attempts to perform conventional inclinings at sea and the difficulties in obtaining precision, before setting out the methods of in-service stability assessment, techniques for analysis of the results and finally the control limits that can be used to trigger further investigation. The technology is suitable for autonomous vessels.
