Sandia National Laboratories - Albuquerque, NM
As the responsible agent for the nation's nuclear weapon stockpile, Sandia National Laboratories' (SNL) Environments Engineering Group maintains the Department of Energy (DOE)/Department of Defense (DOD) Environmental Data Bank. This data bank contains information on identification and quantification of environments the weapons are expected to withstand.
The data bank contains information on specific environments encountered during normal conditions such as transportation, handling, and storage abnormal conditions such as fire, lightning and impact and environmental conditions such as chemical, humidity and pressure. The bulk of this information is stored on physical media such as paper and microfiche and is susceptible to deterioration. Computer storage has only recently become an economical option for data to be placed, stored, and maintained electronically through a program called SPEEDI II. When the data is available on-line, it allows for improved alternatives such as test selection. Actual test data and test reports can also be included.
Other related efforts maintained by the Environments Engineering Group include the LUGSAN II. LUGSAN II is an aircraft compatibility environments analysis package which can perform lug and sway brace analysis calculations for the designer. The designer may input various aircraft, rack designs, maneuvers and hardware, and the system will perform rigid-body analysis to determine the loads to which the weapon will be subjected.
SNL estimates that the program alone has reduced turnaround time on this type of analysis from two weeks to one day. SNL anticipates making this program available to the aircraft manufacturing industry someday.
In addition, the Aging Aircraft Specimen Library Database will be a database to allow a user to point and click on a particular aircraft section for information on all inspection results, Federal Aviation Administration (FAA) regulations pertaining to that part, and any problems associated with that area. SNL maintains that the structure of this database could be directly applicable to other industries such as medicine.
