The Rocket Doc
You Lucky Dog
Lucky is a special dog. She was about a year old when she gave birth to her first litter. I have no idea what happened to the pups. She got pretty sick after, but her owner at Ft Bragg, NC had to give her up with his deployment orders. My daughter Jenni and son-in-law, Pfc Curtis Osborne, rescued her and nursed her back to health. She's very affectionate and very lucky.! This rocket is dedicated to her. I think the rocket colors will be just like Lucky, what I think of as inner city camo,

Started February 15, 2012 with a Rocksim design.
I picked a very simple high altitude, high velocity design. The LOC 3.1" airframe is combined with four delta fins for a 45" rocket. The plan was to use something like a CTI I255RL for an target altitude of ~5000ft and velocity just subsonic. The Tragic Little Aerospace GPS transmitter would be placed in the nose cone to try to find the rocket after deployment of the main chute at apogee. Her is the Rocksim profile. The motor tube was Kraft phenolic, 13" with just two centering rings.
Thrust curve with the CTI I255RL making the target parameters.
Here's the 3D view.
February 18-19, 2012
I lightly sanded the airframe and sprayed it with automotive gray filler primer. Here, it has been sanded with 220 grit. The motor mount and fins are shown after sanding. The 12" ruler is there to get a sense of the scale. I haven't decided on a nose cone yet. What's shown is a LOC 3.1". The fins were sanded and primed gray and sanded again. I primed the airframe with Rustoleum 2X white and sanded down to gray primer (220 grit). A final sanding with 400 grit and it will be ready for paint.
Since there's not much space on the aft centering ring for conventional motor retention, my plan is to use a Giant Leap Bell-shaped nozzle retainer for a neat look.
