The physical form of a buoyancy-propelled-test-body facility and some preliminary test results are described. The facility is a 26-meter-high, 1.067-meter-diameter standpipe which can be filled with water or other liquid. An axisymmetric body rises by buoyancy and is guided up the center on a taut restraining cable. Sensors for measurement of velocity and displacement are incorporated into the guide cable. The standpipe is also equipped to provide pull-down and release of the test body, initial acceleration, and stopping. The confined space of a standpipe within the laboratory permits controlled use of drag reducing polymer in the test liquid and nucleus removal to reduce cavitation. (Modified author abstract)
