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.
An appalling accident rate [5] led individuals such as G. Harry Stine and Vernon Estes to make model rocketry a safe and widespread hobby by developing and publishing the National Association of Rocketry Model Rocket Safety Code, and by commercially producing safe, professionally designed and manufactured model rocket motors. Model rocketry by ...
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.
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 ...
Jetex 100 - the first Jetex motor Aeromodeller June 1948 Jetex Tailored Skyray kit. The Jetex motor is a miniature solid-fuel rocket motor produced for use as a powerplant for flying model aircraft. Its production led to a number of imitators and, after its discontinuation, successors of similar type.
Cox Models, a former division of Estes Industries of Penrose, Colorado, was a multimillion-dollar hobby company, is one of the hobby industry's oldest companies and is noted for its production of miniature model internal-combustion engines.
Vernon Estes (usually referred to as Vern), born January 4, 1930, is the founder and namesake of Estes Industries, the highly recognized model rocket production company, headquartered in Penrose, Colorado. In 1957, G. Harry Stine and Orville Carlisle founded the first model rocket company, Model Missiles Incorporated, in Denver, Colorado. By ...
