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.
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.

The aerospike engine is a type of rocket engine that maintains its aerodynamic efficiency across a wide range of altitudes. [1] It belongs to the class of altitude compensating nozzle engines. [ 2 ] Aerospike engines were proposed for many single-stage-to-orbit (SSTO) designs.
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 ...
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.
