Document Review Criteria for the “Future of Ground Testing” Working Group
Draft by Dunn, 2/25/15
Note: The focus of this report is ground testing. We will include information on flight testing as it is
included in our reference material. We may need an additional effort to beef up the FT info.

ii. Support to flight testing
iii. Measurement and instrumentation technologies maturation, including teaming to
define needs to measurement developers and producers (again, integrated with CFD
and flight test)
iv. Government and industry development, proprietary versus open source
III. EFD/Ground Testing Technology Gaps and Impediments
a. [Note: This is likely a work product from assessing the first two sections. Included to capture
anything identified in the references.]
IV. Technology Development Plan
a. [Address the gaps]
Additional Considerations
There will be additional info that doesn’t fit into the above categories and we still need to capture that
and then figure out how it fits into our paper. The following is a start at some of this potential info.
V. Internal and External Environments
a. Interdependencies within the RDT&E process and risks associated with potential loss of GT
capabilities
i. Example: Accepting higher risk by not understanding product performance such that
defects appear late in the RDT&E life cycle -- very costly to fix late
b. Facility owner needs and issues
i. Mission requirements and priorities
ii. Condition of facilities
b.
c.
d.
e.
iii. Capability sustainment efficacy (maintenance, investments, skill management,
operations and maintenance processes, budgets and business processes
iv. Improvement and modernization alignment with future market needs
v. Customer focus/service
Producer risk management needs and issues
i. [Definition note: risk management is the definition of hazards, the probability a
hazard will happen, the potential severity/impact when it happens, an initial risk
level assessment, development and application of specific mitigators to a high risk
hazard, and a reassessment of risk with mitigators in place. Process continues until
hazards are well understood and risk levels have been mitigated down to acceptable
levels.]
ii. Always a trade to define GT and CFD requirements to drive risk down for specific
hazards
iii. CFD mostly requires validation (typically via GT or FT)
iv. GT and CFD also used to define some hazards
Economic impacts
i. United States, EU and Great Britain, Japan
ii. Breakouts based on GDP, jobs, net imports/exports
iii. Technology spin-offs, estimate of additional positive impact on GDP
Education impact (STEM support,
Environmental headwinds and support (in addition to cited above, add geopolitical
considerations, overall economic indicators, national and international politics
(regulations/laws, taxation, market support or not, more)
VI. Needs and Capabilities
a. Computational methods
i. Code validation
ii. Interactive development
b. Flight testing investigations
c. In service product anomaly investigations
d. Measurement and instrumentation technologies development
e. Role in RDT&E process, at each stage; percent and relative importance of knowledge
gained at each stage; degree of risk identified and managed at each stage for different
kinds of systems at different levels of maturation
f. Market environment, growing, stagnant/mature, declining, cyclical
i. Low/subsonic speed
ii. Transonic speed
iii. Supersonic speed
iv. Hypersonic speed
