I've been in this hobby a very short time and have achieved my Level 1 & 2 certifications. Now it's time to start building my level-3 certification rocket. After attaining my Level 3 goal I plan on concentrating on clustering and multi-staging. So I wanted my Level 3 Project to be a scratch built rocket, not a kit. It had to be a simple design capable of Level 3 and still be used with K & L motors. I'm going with simple, "three fins and a nose cone" rocket. I decided to build a simple rocket that would fall into the category of a basic rocket! My simple rocket would have three fins, would use dual deployment, breaking above the booster section to deploy the drogue chute and between the upper payload section and nose cone for the main chute. I decided on a 4" airframe as a size that is easy to work with and would still allow future launches with a wide variety of K and L motors. As a good rule of thumb, I started using a 20:1 length to diameter ratio, yielding an 6'5" rocket, then added an altimeter bay and adjusted the length to accommodate motor, motor tube, baffle system, thus ending up with a 9'6"' rocket. This is still a handy size, while being large enough to handle a full M. So I plan a single motor mount for a 75mm motor (Level-3 certifications cannot be multi-stage or use clustering). The data capture table and various diagrams are referenced in the appropriate sections. Printed versions of all information have also been submitted to the TAP members. The entire airframe will be
built after the modification of my Level 2 "Endeavour" to dual deployment
simulating the design of "Miss Fire" with the dual deployment system and
the recovery system outlined above to make it more reliable. Ejecting the
'chutes' out of the tube, I split the airframe for recovery at the point
where the charges were located above and below the altimeter bay located
in the center of the rocket. This means that the parachutes and rigging
are pushed out of the tube after separation. This rearward and forward
deployment worked very well with my modified Endeavour as planned for "Miss
Fire" design.
