Hi all
Im new to the Association and have been playing with rockets on and off over the years, just for fun mostly. I am in the midst of designing a rocket to be 3d printed in a flexible plastic. Looking at the attachment does this rocket look flyable?
I wasn't intending to have any extra tubing on the rocket and my purpose in creating it was to make as smaller rocket as i could. I did make a rocket once that was very similar in design and it flew brilliantly, with a short body and long fins, true the body was slightly longer, the fins were longer and it had three fins instead of four but it seems similar enough to me.
I tested the rockets parameters in the nasa rocket modeler simulater and it flew slightly further than a standard rocket design.
The guide tube is 4mm wide in the hole and i thought it might be a bit small if i made it smaller, i do have concerns of the change of flight path due air friction on the guide tube, more than the length of the tube , i usually use drinking straws.
The rocket will be loaded with a small bit of wadding to stop the rockets backfire from burning the inside of the cone or body and will also have a primitive parachute or ribbon to slow the decent.
my main concern is the rocket flipping due to incorrect center of gravity. as of the danger of the first flight i will be launching it at the beach, away from everyone.. also the solid engine heating and fusing to the plastic is a problem. there should be enough of a lip at the top to prevent the engine flying straight out the top of the rocket
Can anyone give me some feedback on this rocket design? and any changes i can make to have it perform better while still keeping the rocket similar to my design
