High-power rockets are defined as rockets flown using commercially available motors ranging from H to O class. In the U.S., the NFPA1122 standard dictates guidelines for model rocketry, while NFPA1127 is specific to high-power rockets. In most U.S. states NFPA1122 has been adopted as part of the legal code. A smaller number of states use NFPA1127.
It supports all aspects of safe consumer sport rocket flying, from small model rockets with youth groups to very large high-power rockets flown by adult hobbyists. [4] The NAR is a recognized national authority for performance and reliability certification of consumer rocket motors and for the certification of high-power rocket fliers in the U.S.
Gordon Mandell of the M.I.T. Model Rocket Society designed a model-rocket engine powered monocopter, which he named "turbocopter," and published the design concept in his column "Wayward Wind" in Model Rocketry Magazine in 1969. A later version of this was researched at MIT in 1980. [19]
The largest vendors of high-power rocket motors in the world are Cesaroni Technology Inc. and RCS Rocket Motor Components, Inc. The very first model rocket motor certified was by Model Missiles Inc. (Orville Carslile). Circa 1958. The very first high-power rocket motor certified was by U.S. Rockets (Jerry Irvine). Circa 1985.
Gates is an avid member of the high-power rocketry community, frequently flying large model rockets in California and Nevada. To facilitate his hobby, Gates started a side company, Gates Brothers Rocketry, with his brother, Erik Gates.
This is a competition between chapters designed to challenge students in high-power rocketry. [12] The goal of the competition is to launch a rocket, designed and built by the chapter members, to an altitude of 10,000 feet above sea-level. This competition has now successfully been running since 2011. The winner of the 2012 competition was ...
SHREWSBURY — Shrewsbury High School students will head to Plains, Virginia, this month to compete in the American Rocketry Challenge. It is the world's largest rocket contest and has around ...
A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere.
