The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...
Estes Industries was founded by Vernon Estes in 1958; in 1961, the company moved to a 77-acre tract of land on the outskirts of Penrose, Colorado. [10] [1] In 1969, Vernon sold the company to the Damon Corporation of Needham, Massachusetts, a company which also purchased a number of other hobby companies including a smaller competitor of Estes, Centuri Engineering of Phoenix, Arizona.

A model rocket is a small rocket designed to reach low altitudes (e.g., 100–500 m (330–1,640 ft) for a 30 g (1.1 oz) model) and be recovered by a variety of means. According to the United States National Association of Rocketry (NAR) 's Safety Code, [ 1 ] model rockets are constructed out of lightweight and non metallic parts.

Liquid rocket fuel. Oxidizer. Pumps carry the fuel and oxidizer. The combustion chamber mixes and burns the two liquids. The hot exhaust is choked at the throat, which, among other things, dictates the amount of thrust produced. Exhaust exits the rocket.
The pulse rocket motor allows the motor to be burned in segments (or pulses) that burn until completion of that segment. The next segment can be ignited on command by either an onboard algorithm or in a pre-planned sequence. All of the segments are contained in a single rocket motor case, as opposed to staged rocket motors. [1]
