A Primer on Scientific Test & Analysis Techniques (STAT) - Mark J. Kiemele, Ph.D, Air Academy Associates

(8:00am-12:00pm)

With the increased emphasis that the Department of Defense is placing on the use of scientific principles in the test and evaluation environment, you may have heard of the term STAT (Scientific Test and Analysis Techniques).  This 4-hour tutorial will provide an overview of some of the most important scientific test and analysis techniques that can and should be used in test and evaluation activities.  This session is meant for executives, leaders, managers, and practitioners who need to know what STAT includes and what it can do for their organizations even if they themselves never design a test or evaluate its results.  Design of Experiments (DOE) is most definitely a critical component of STAT, but this session will address other important tools as well.  Methods for prioritizing requirements and translating them into measurable entities will be discussed, along with Measurement System Analysis (MSA).   MSA should answer the question of whether we can trust the data that we are getting from the test.  Transfer functions and their use in prediction and optimization will also be presented.  After this session, leaders, managers, and practitioners will have a high-level understanding of a variety of methods that are implicit in STAT.  No prior statistical prowess is needed to garner some key principles/take-aways from this session.


Dynamic Pressure Measurement Instrumentation - Mr. Joseph (Steve) Carter and Adam Hurst, PhD, PE, Kulite Semiconductor Products, Inc.

(8:00am-12:00pm)

The measurement of unsteady or dynamic pressures is critical for airframe and gas turbine health monitoring, design validation, research and active flight/engine control. Unsteady pressures exist throughout flight regimes and rotating machinery that can lead to phenomena such as rotating stall and surge in the compressor, flow instabilities, low and high cycle fatigue, accelerated component wear, screech and rumble in gas turbine augmentors as well as noise pollution. Proper characterization of wideband pressure levels within ground test and flight is critical so that engineers can be better equipped to mitigate undesirable dynamic pressures in weapons platform development or production.


Introduction to Python with Engineering Applications - Mr. Phillip Rogers, 812 TSS/ENT Edwards AFB

(1:00pm - 5:00pm)

This tutorial is intended for flight test practitioners interested in using Python. Python is a general purpose interpreted programming language. Python emphasizes code readability and reuse. There are many add-on packages that make Python suitable for scientific computing, such as the SciPy packages. Also, Python can be used for “ad hoc” analysis and “what if” explorations.

 Python supports object oriented design, dynamic variable typing, automatic memory management, and has an extensive and comprehensive set of application libraries.

Because Python is interpreted (like MATLAB) it is easily modified and run. This tutorial presents an introduction to Python that covers:

    • Numbers, variables, basic operations
    • Strings, lists, dictionaries, and related Python data structures
    • Modules and functions
    • Python packages: NumPy, MatPlotLib, SciPy, Pandas
    • Reading / writing files

Engineering application of Python presented includes an example of analyzing an aircraft flight maneuver and determining particular data characteristics at certain events.


HD Transport, Timing and Compression - Mr. Paul Hightower, President and CEO, Instrumentation Technology Systems

(8:00am-12:00pm) 

While many of the terms used in digital video are the same, the nature of digital video is quite different from analog video. As a first step in understanding what vertical sync, horizontal sync and resolution means in the digital video world this presentation will compare these terms side by side. This tutorial will describe the commonly used formats and their variations. It will be shown how resolution is 3-dimensional in digital video and that these dimensions are affected by compression in several ways. Timing is another critical measurement in engineering test. In analog video time stamping at frame sync was customarily done at the destination. Time was consistent and delays due to transport were in microseconds. In digital video that may still be true when directly connected, but when transporting HD digital video more than 300 feet, the need to compress may be the only alternative. Compression introduces latencies that may be 70 milliseconds, but could just as easily be 10 seconds. The latency at any point in time varies. Reliable time stamping may only be possible at the source. These issues will be discussed along with possible solutions.


Performance-based Sensor Selection, GI-GO (Garbage In – Garbage Out, OR Good Input – Good Output?)
- Mr. Jon Wilson, Principal Consultant, Jon S. Wilson Consulting, LLC.

(8:00am-5:00pm)

This tutorial is intended for engineers, program managers and technicians who want a better understanding of transducer characteristics and specifications. It is presented from the viewpoint of a user who also has experience marketing transducers, rather than from that of a manufacturer. Participants will learn how to interpret transducer specifications, define necessary performance characteristics for specific applications, and how to select the best transducer for their applications.

The following topics will be addressed in detail:

  • The Ideal Transducer
  • Basic Transducer Mechanisms
  • Transducer Performance Characteristics
  • Transducer Environmental Effects
  • Cabling and Interconnections
  • Signal Conditioning Considerations
  • Participants’ Specific Problems or Instructor’s Case Study


Practical Considerations using Pressure, Force, Acceleration and Torque Instrumentation - Bill Zwolinski, Head, Test and Measurement (Americas), Kistler Instrument Corp 

(8:00am-12:00pm)

This tutorial will l explore the what’s, why’s and how’s related to using Pressure, Force, Acceleration and Torque instrumentation and solve various application problems. The tutorial will cover the concepts of operation and technology review for Piezoelectric (PE), Integrated Electronics Piezoelectric (IEPE), Microelectromechanical Systems (MEMS) and Piezo-resistive (PR)/Strain Gage instrumentation. Practical considerations include the explanation of key performance specifications, selection criteria, installation, cabling and checkout. Several applications will be discussed to illustrate the concepts including military and aerospace. Active demos will be used to highlight various concepts as well as DAQ/signal conditioning.


TENA and JMETC - Overcoming Challenges in Distributed T&E - Gene Hudgins, Wyle 

(1:00pm - 5:00pm)

The Test and Training Enabling Architecture (TENA), along with the Joint Mission Environment Test Capability (JMETC), provides the persistent and robust infrastructure (architecture, network, integration software, tools, reuse repository) and technical expertise to integrate live, virtual, and constructive (LVC) systems for test and evaluation (T&E). The combination of the two reduce T&E time and cost by offering readily-available persistent connectivity, standing network security agreements, and interoperability software for integrating test assets, as well as providing certified test tools for distributed and net-centric testing. This tutorial will inform the audience as to the current impact of TENA and JMETC on the Test, Training, and Evaluation community; and its expected future benefits to the range community and the warfighter.


Troubleshooting Ethernet Data with Wireshark - Mr. Paul Ferrill, ATAC 

(1:00pm - 5:00pm)

The “Troubleshooting Ethernet Data with Wireshark” tutorial will use real-world aircraft data to demonstrate how to use the open source program Wireshark to both view data and troubleshoot problems. The class will include presentation and hands-on usage of Wireshark to look at data as if you were connected to the Ethernet network on an airplane and if you were connected to an IRIG 106 Chapter 10 recorder broadcasting data over UDP. We’ll start out with a brief overview of Ethernet fundamentals and then get right on to using Wireshark.
