An altitude of 10.3 km was reached, making it the highest verified altitude achieved in Africa by an amateur group. This was an especially notable achievement as the propellant was based on Ammonium Nitrate, as opposed to the more common ammonium perchlorate. All major components used were manufactured in South Africa, including electronics and ...
Model rocketry is a safe and widespread hobby. Individuals such as G. Harry Stine and Vernon Estes helped to ensure this by developing and publishing the NAR Model Rocket Safety Codes [1] [13] [14] and by commercially producing safe, professionally designed and manufactured model rocket motors.
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 ...
A motor with 1 kilogram (2.2 lb) of propellant is a K impulse motor, so model rocketeers can now fly level 2 models without the need for an explosives license, however an RCA is still required. This relaxation in the regulations has made mid and high power rocketry much more accessible in the UK. [citation needed]
The first Mini Sugar Shot rocket, a single-stage dual-pulse design motor prototype of the Extreme Sugar Shot rocket, reached an altitude of 4 kilometres (2.5 mi) before a catastrophic motor malfunction occurred; contact with the second Mini Sugar Shot rocket was lost at an altitude of nearly 6 kilometres (3.7 mi) going in excess of Mach 1. In ...
The zero-length launch system or zero-length take-off system (ZLL, ZLTO, ZEL, ZELL) was a method whereby jet fighters and attack aircraft could be near-vertically launched using rocket motors to rapidly gain speed and altitude. Such rocket boosters were limited to a short-burn duration, being typically solid-fuel and suitable for only a single ...
