Can *we* administer a shot of oooooowwww, about 120-125psi of Helium gas to the cone?
AFAIK, there is no restriction to any method of adjusting the Cg as long as you preserve stability. So sure, if you want to add weight to the nose cone, go for it.
When you pressurize Helium (or any gas), you increase its density and thereby defeat the intended benefit (of being lighter than air)
Assuming the temperature and volume remain constant, you increase the molecules of Helium in direct proportion to pressure. PV=nRT
At standard temperature and at sea level, dry air has a density of 1.2754 kg/m3 and a pressure of 14.7 psi, Helium = 0.178 kg/m3.
So, if you pump helium to 125 psi you increase its density by a factor of 8.5 (125 psi / 14.7 psi), making it 1.51 kg/m3, or 1.18 times HEAVIER than air.
Because the helium atom is very small, it can easily diffuse through many materials, so that the pressurized volume will deflate quickly.
The method (valve, plug, ...) you use to contain the pressurized Helium will add even more weight (and some drag) to the nose cone as well.
And just to make sure Gus will read this far... Kari Byron is a red-head.
