Model Forum / General / Rockets / June 2006

I ran across a couple of news clippings from the 1930s laid in the pages of
a book I'm scanning. They both deal with very early American amateur rocket
launches. One make specific reference to "American Interplanetary Society"
and has a wire photo attached. Date is probably about ...

Exactly what does the term convolutely-wound mean? Can you back it up with a

I made some tooling to form the core of my composite propellant grain.  I
went to the local plastic shop to buy release for fiberglass.  I cast the
propellant in the casting tube with the released core tooling in place.
After the propellant cured I tried removing the core tooling.  ...

But doesn't this make the altimeter continuity check useless?  It will
