goddard project

its gonna be about 34" when im done

the thing is in the picture those little thrust things out of the engine mount

if i made some of those out of metal (off an unbrella thats gonna be the chute) would they interfear with the rocket flight?

As long as you have them extend parallel to the motor you should be fine. You wouldn't want them assymetrically deflecting the exhaust.

You should go looka the the Goddard rocket at the Udvar-Hazy center.

oh fer sur :D

It actually flew very well. In fact, it flew better than *Goddard's* version. It would fly on A8, B6 and C6 motors, though with C6 it would get a little squirley towards the end of the boost.

The "fuel tubes" were 1/8" wood dowel.

Here is a picture of one that Brian McCarthy designed years ago that was about 2.5 times the size of mine, using BT-5 as the fuel tubes. This one flew about the same as Goddard's original as far as altitude. Both version flew suprizingly straight and had good recovery too.

Goddard's original design was to build a rocket that would use multiple rocket engines; not stages or clusters like we're used to, but loaded into a chamber like bullets in a revolver. He only decided to use liquid fuel after spending many thousands of dollars trying (and failing) to develop his dream. Maybe you'd have better luck, Jim :)

I'd ask you to post plans, but I don't need yet <i>another</i> rocket to work on... :D
