March 2020 – The Right Mix of T&E Infrastructure
To accomplish our jobs as Test and Evaluation (T&E) professionals, we need the right mix of infrastructure to support our mission. As our systems evolve and become increasingly complex, the “right mix” of infrastructure must also evolve to keep pace. This issue contains a variety of articles that reflect the diverse infrastructure needs of the T&E community.
In this issue, we are experimenting with a few new types of articles. We have included an historical perspectives article and two short technical articles.
In our historical perspectives article, Christian Gelzer reflects on the longest flight in the X-15. In the first technical short article, Joseph Crossin discusses developing the next generation of radars that will leverage emerging technologies such as 5G wireless networks. In the next technical short article, Guenever Aldrich and Tomasz Wojtaszek discuss the need for collaboration to achieve spectrum sharing. I enjoyed reading these contributions and welcome your feedback on these new article ideas. Our technical articles reflect a wide range of T&E infrastructure needs.
Brian Mork, Col USAF (Ret), Ph.D. from the Air Force Research Lab authored an article on a “Three Dimensional Cyber Risk Model.” He highlights that we need to move beyond two-dimensional risk assessments when an intelligent adversary is involved. He shows how thinking in three dimensions can provide better decision making for design engineers, program managers, and red teams that devise cyber combat theories.
In the next article, Huat Ng and Wayne Devereux from KBR highlight the importance of Live Virtual and Constructive (LVC) environments in test design. Noting the recent and substantial advances in models and simulations made possible by advances in information technology and visualization, they highlight that now is an ideal time to incorporate more models and simulations in test design. They highlight that these methods can model more complex environments than available on operational test ranges and inform conditions for operational testing. Finally, they provide a decision flow chart for leveraging LVC in test design. An electricaloptical/infrared sensor case study reinforces their ideas.
MAJ Kurt Klingensmith and Jon Alt, Ph.D. from the Research and Analysis Center in Monterey contributed an article on “A Systems Architecting and Engineering Approach to Creating Enterprise Data Strategy.” This article highlights how data curation is a critical element of test infrastructure. They provide overall architecture and examples of functional decomposition for various stages of data management to guide the reader to an enterprise data strategy. Themes they highlight that should resonate with ITEA readers are that data is an enterprise asset, leveraging it requires an educated workforce, and that data strategies address people, processes, and technologies.
In the article, “Homeland Security Test & Evaluation Infrastructure: It’s Time to Add to the Mix,” Wayne Dumais, Deputy Director for the Office of Test and Evaluation at the Department of Homeland Security (DHS), highlights the broad range of DHS missions and the corresponding infrastructure needs. He advocates for a consortium approach to developing T&E infrastructure for homeland security missions including the DoD, academia, and industry. One of the many interesting challenges Wayne highlights is the construction of tunnels for T&E purposes. He ponders how one constructs these tunnels so that they meet safety standards, but also reflect the operational mission.
In the article, “Directed Energy Wind Tunnels,” the authors reinforce the need for leveraging modeling and simulation as part of an integrated test program. This article reinforces the themes in the article on LVC for testing. It shows the advantage of using a combination of computational fluid dynamic simulations, wind tunnel testing, and flight test. Their work is motivated by the important role that directed energy will play in future US Air Force aircraft. They highlight that these results should provide a rational for incorporating models, simulations, and ground test into integrated test and evaluation strategies for future programs of record.
In the final article, Bryan S. Kelly, Lt. Col. USAF, highlights the need for automated regression testing for aircraft implementing agile software development. An issue that many of us face is the growing complexity of software on all platforms. Kelly highlights the importance of software quality through historical examples.
He provides a case study for the F-16 Center Display Unit. He advocates for broad Air Force adoption of automated regression testing noting that the current manual test methods are not responsive to the Air Force’s adoption of agile software development.
Enjoy the issue!
