Abstract
A method of fabricating a high-altitude balloon. The method includes coextruding at least two adjacent continuous layers of extrudate, extrusion-bonding the layers of extrudate to one another along an edge of the sheets of extrudate to form a seam, and cooling the extrudate.
Claims9
A method of fabricating a high-altitude balloon comprising:
- simultaneously extruding at least two balloon panel extrudate layers and at least one delaminator extrudate layer;
- bonding a first portion of a first one of the balloon panel extrudate layers to a first portion of a second one of the balloon panel extrudate layers,
- whereby a second portion of the first balloon panel extrudate layers can delaminate from a second portion of the second balloon panel extrudate layers to define a balloon envelope cavity upon inflation.
A method of fabricating a high-altitude balloon comprising:
- simultaneously extruding at least three balloon panel extrudate layers with a single extrudate melt curtain;
- and
- bonding a first portion of a first one of the balloon panel extrudate layers to a first portion of a second one of the balloon panel extrudate layers and to a first portion of a third one of the balloon panel extrudate layers,
- whereby a second portion of each of the balloon panel extrudate layers is not permanently bonded to either of the other balloon panel extrudate layers.
