Vertigo

     Hello.  Just wanted to let everyone know that I am beginning a huge project for the semester.  High powered rockets are fun to build and fly.  The rocket science behind even the simplest of models can be staggering when it comes to optimizing performance, but I wanted a bigger challenge.  What if I could make a rocket that is about 10lbs... with no parachute!!!!
    It's possible! The recovery system is called auto-rotation.  The process of auto-rotation is used by helicopters already to safely land when their engine dies.  The spinning blades provide enough drag to slow the descent velocity to a safe speed.  Theoretically it sounds simple, but implementing this on a rocket is going to be a long process.
    I started with a simple design using a triangular body tube that unfolds into 3 airfoils.  But, after consulting with an expert, decided to go with an 8-blade system that out from a cylindrical body tube.  The motor we are currently considering is a Cesaroni Pro-54 or Pro-38, impulse class J.  This should provide plenty of thrust for our heavy rocket, but not send it to a soaring apogee or transonic speeds.
    As we prototype and design parts for this rocket, I will post them on the blog.  This project will certainly test feline advancement in aeronautics!
