_Warheads?_?
If I so happened to attatch a mortar shell (the firework type that fire out of the tubes. Also the icecream looking shells(with the ball on top) not the cylindrical ones) to a model rocket. What would the expected outcome be when launched?
Mind you I have everything set up on the inside with the fuse connected to the engine. So after the engine burns up, the fuse will light, and somewhere between it's apex and the ground it should explode.
I'm just worried though that the top might be too heavy, so when launched it will lean and shoot in a different direction other than up.
I was wondering if the rounded nose of the rocket would make the aerodynamics worse, and if the top is too heavy. Because normally the bottom would be heavier due to the engine but such is not the case. Will it screw up it's flight path completely?
Would it also be a good idea to add fins near the top of the rocket? (currently it only has four on the bottom)
Any advice
It's likely to be unstable since your CG (center of gravity) will be towards the top, and you want it towards the bottom. Also, the mass increas to carry the shell will be a significant detractor to the performance of the rocket itself, unless you have something fairly massive. The fins won't buy you much at the top, you need the drag at the bottom to overcome any instabilities in the thrust vector and torque about the CG.
Basically, this is not a good idea. Most likely, the rocket will fire, it will carreen and spin and most likely crash back on the ground, ultimately lighting off the mortar for a spectacular ground blast - probably catching you or your neighbors house on fire...lol
It's not that it cant work, you just need to build a custom rocket that controls these variables.
