Throcky the high power ballistic rocket

High power rocketry (HPR) means launching rockets that are larger, faster and more powerful than typical model rockets. These rockets that classify as HPR exceed impulse classes above 160 Newton-seconds and require special certifications to fly in the US. Getting certified to fly higher power motors allows me to be able to build larger projects, experiment more, and practice more skills in rocketry. With faster flying rockets stable design becomes important, introducing the opportunity to practice machining, composite work and FEA. When teams of engineers get certified together (like we do with the Lehigh Rocketry Team), we all get to learn and watch each other develop. 

NAR stands for the National Association of Rocketry, and its the main U.S. organization that sets saftey standards, provides insurance, and offers certifications for hugh power rocketry. Levels of certification go from L1 to L3. L1 solid motors are about the size of a plastic water bottle, L2 a baseball bat or large thermos, and L3 like a fire extinguisher or small propane tank and above. Gaining certification is done through a series of flights using higher class motors, and proving you can design, build, and safely recover your system. I currently hold my level 1 certification, and aim to get my level 2 this year.
