We&#039;ll carve out relatively closely fitted voids to hold the various components.<br /> <br /> Shape considerations:<br /> * balloon sheds turbulence during ascent; torpedo shape might be best for that<br /> * APRS antenna with a 19&quot; radius ground plane parallel to the ground would reduce signal energy sent upwards<br /> <br /> Michael&#039;s original email:<br /> <br /> Notes on foam:<br /> <br /> *) Probably want XPS (eXtruded PolyStyrene). This is a water proof, dimensionally stable, grain free foam. It tolerates very low temperatures well, and doesn&#039;t burn easily. <br /> It cuts easily and cleanly with a sharp knife. It doesn&#039;t crumble or shed. <br /> <br /> Brand names are &#039;Dow Hi-Load 60&#039; or &#039;Corning Foamular 600&#039;. Foamular 250 should work just fine (the difference in the number is the compression strength). <br /> <br /> It appears that places like Lowes carry it, and it costs ~ $15 for a 2 foot by 8 foot by 2 inch block.<br /> (which is probably enough for about 70 million flights).<br /> <br /> [[Category:SpacebridgeBravoLaunch]]</div>
