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.
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.
Model and high-power rockets are designed to be safely recovered and flown repeatedly. The most common recovery methods are parachute and streamer. The parachute is usually blown out by the engine's ejection charge, which pops off the nose cone. The parachute is attached to the nose cone, making it pull the parachute out and make a soft landing.

High-power rocket liftoff. Any model rocket using a single motor greater than 160 Newton-seconds of total impulse, or multiple motors with a total thrust of 320 Newton-seconds, is propelled by a combination of motors having a total of more than 125 grams (4.4 oz) of propellant weight, or weighs more than 1,500 grams (53 ounces) with motors ...
It has similar weight, thrust and duration to Jetex, allowing many old plans for Jetex powered models to be built and flown with the new motors. The Rapier is a single use motor with a cardboard case and a ceramic nozzle, visually closer to a model rocket motor than the original reloadable Jetex.
Two giant rocket motors required to display the retired NASA space shuttle Endeavour as if it's about to blast off arrived Wednesday at a Los Angeles museum, completing their long journey from the ...
The P160C is a solid-fuel rocket engine designed for use as the first stage of the Vega-E and as the boosters of the Ariane 6 Block 2 launch vehicles. The solid rocket motors were developed by Europropulsion, a joint venture of Avio and ArianeGroup, for the European Space Agency. The "C" in the name signifies its "Common" use across these ...
