When the idea of an engine hacks theme was being kicked around at Hack a Day, the subject of rocket engines was one of the first to come up. First up is [Robert Watzlavick], who has been has been building liquid fueled engines for the last decade. As with many of the early rockets that launched man into space, [Robert] uses kerosene and liquid oxygen for fuel. This man knows his stuff.
Engine Hacks: Liquid Fuel Amateur Rocket Roundup
Rocket candy - Wikipedia
Amateur rocketry , sometimes known as experimental rocketry or amateur experimental rocketry , is a hobby in which participants experiment with fuels and make their own rocket motors, launching a wide variety of types and sizes of rockets. Amateur rocketeers have been responsible for significant research into hybrid rocket motors, and have built and flown a variety of solid, liquid, and hybrid propellant motors. Amateur rocketry was an especially popular hobby in the late s and early s following the launch of Sputnik , as described in Homer Hickam 's memoir Rocket Boys. One of the first organizations set up in the US to engage in amateur rocketry was the Pacific Rocket Society established in California in the early s. The group did their research on rockets from a launch site deep in the Mojave Desert.

There is quite a number of propellants used in experimental rocketry and often people will get attached to one type or another and become quite knowledgeable about that propellant. The three most common types of propellants are compressed powder, usually black powder, sugar propellant most commonly sucrose, dextrose and most recently, sorbitol and composite propellant using ammonium nitrate or ammonium perchlorate as the oxidizer and a powdered metal usually aluminum or magnesium as the fuel. There are three well known people who are "experts" in each of these propellants: David Sleeter Teleflite Corporation has a book on black powder motors "Amateur Rocket Motor Construction. Richard Nakka is the sugar rocket specialist and has the most comprehensive experimental rocketry website bar none. In rocketry, the propellant is compressed or cast into large forms just smaller than the motor diameter.
