Data reduction system for the XR-3 Captured Air Bubble testcraft.
datareductionsys00dabb.pdf (4.264Mb)Abstract
A fast, accurate and portable data reduction system
was developed for the XR-3 Captured Air Bubble testcraft
being evaluated at the Naval Postgraduate School, Monterey,
California. The system consists of four units. A magnetic
tape recorder is used for data play back. A signal conditioner
unit with a built-in analog-to-digital converter was
developed and is used to filter, amplify, sum and further
prepare the data for transmission to either a strip chart
recorder or a digital X-Y plotter through a Monroe 1880
calculator.
Preliminary use of curve fitting techniques are discussed;
.calculator programming and the various problems
and solutions encountered in the development of the system
are described.
