ON A CAUSE OF FAILURE OF HIGH ALTITUDE PLASTIC BALLOONS.

Abstract

In a search for causes of failure of plastic balloons, an experiment which simulates the stresses and temperatures in part of a balloon during launch and ascent was conceived and then tests using a number of balloon films were conducted. The test sample is a cylinder formed by heat sealing two long film strips along the edges. In the test the film cylinder, which is closed at both ends, is preloaded axially at a temperature encountered at launch, after a time interval cooled to -70F, and then pressurized until it bursts. Tests were conducted on samples made of StratoFilm 54 inch layflat tubes, DFD-5500 54 inch layflat tubes and DFD-5500 33 inch layflat tubes. All tested films were 2 mils thick. (Author)
