Hello fellow rocketeers,
Last summer I returned to model rockets after a 35 year break. At first the interest was kindled by my 10 year old grandson. That interest has grown into a full-on obsession and now I have built and launched over 20 rockets ranging from mini engines to G size rockets.
I am now building an AT G-Force for the sole intent of obtaining my L1 certification. I've built the motor mount/fin can with 15 and 30 minute epoxy so I believe that part of the rocket will withstand either an H128 or H182 thrust and acceleration.
I am conflicted as to whether to have the rocket separate in the middle as designed or have the nose cone deploy alone. I have removed the labyrinth from the end cap at the top of the motor tube and so I won't be using the mesh. I'll be using a 12X12 Nomex blanket for chute protection.
Arguments for each side are:
Nose Cone deploy:
1. I can use my Jolly Logic Chute Deployment device without subjecting it to an excessive amount of heat and contamination from the ejection charge.
2. The nose cone slips into the body tube much easier than the paper to paper of the body tube to coupler fitment. I can adjust the slip much more precisely.
Break in the middle:
1. The ejection charge doesn't need to fill as large of a cavity to make the separation.
2. When the rocket lands it will have its weight split over two pieces and won't hit so hard on the ground.
I would love to hear from those who have used these deployment options - or anything else for that matter and get first-hand information so I can make the right decision.
Any suggestions are greatly appreciated. Thanks in advance.
