A Look Inside a Composite Rocket Motor

I don’t normally re-post things found in other rocketry blogs, but the video posted recently in R2K’s High Power Rocketry Blog is just too cool not to share. The video is an animation which illustrates the assembly and function of a typical APCP composite propellant rocket motor as used in many hobby rockets.

Team America Rocketry Challenge

Team America Rocketry Challenge (TARC) is an annual rocketry competition for students in grades 7 through 12. Sponsored primarily by the National Association of Rocketry (NAR) and the Aerospace Industries Association, TARC is designed to encourage students to study math and science and pursue careers in aerospace.

TARC is open to teams from schools or non-profit organizations. Each year’s competition is limited to 750 teams. The teams build and fly rockets designed to meet specific requirements and goals which are different each year. As an example, in 2011, teams had to design, build, and demonstrate a model rocket that carried a raw egg to an altitude as close to 750 feet as possible and stayed airborne for between 40 and 45 seconds using only a single 15-inch diameter parachute as the recovery system.

Each team makes qualifying flights and a score is computed based on how close the rocket meets the contest’s goals. The teams
