It would offer interesting possibilities, which would also make it a good educational rocket. For example:
By inflating it with helium instead of air so that it would be lighter (I don't think it could be made neutrally buoyant due to the weight of its fins and motor mount [the inflatable hull envelope by itself might be light enough to become so, though]), one might achieve long flight durations even with its lowest-impulse recommended motors, or:
By inflating it with a gas that's heavier than air (xenon would be interesting, but very expensive; carbon dioxide or carbon tetrachloride [CCl4 is only dangerous in large quantities, or in the presence of hot copper or brass] would be good alternatives), it should coast higher because it would then have a greater mass/frontal area ratio. |
