Abstract : The Experimental Research Section of the Aero Structures Division, Aircraft and Crew Systems Technology Department Naval Air Warfare Center, Aircraft Division, Warminster, PA is responsible for structural testing of a variety of different types and sizes of specimens. The purpose of these tests range from characterization of material systems to qualifying substructures for flight certification. Previously, simple tests were done with limited spectrum fatigue capabilities and little or no real time data acquisition capability. More complicated tests were done on the lab's Hewlett-Packard HP-1000 computer. To expand the capability of the laboratory, five Hewlett-Packard HP-9826 desktop computers with HP-6940B multiprogrammers were purchased. These small desktop systems have all the capabilities of the HP-1000 but with a limited data acquisition and storage. Now a variety of tests can be performed on the desktop computers, from small static tests to spectrum fatigue tests, leaving the HP-1000 available for tests that require large data acquisition. It is not possible to generate generic software for use on a variety of test programs since the testing pedometers (loading configuration, data acquisition, fatigue spectrum, etc.) can vary significantly. Instead, software was developed specifically for one program, with the intent to identify test-specific requirements that can be modified for other programs.
