Amateur rocket
As amateur rocketry refers missiles in amateur or semi-professional area that is not certain criteria such as model rockets or high-power rocket subject. This includes, for example, the use of non-breakable, heavy components as well as standardized motors that are not produced in series.
Definition of terms
The term amateur rocket building developed in the United States in the 1950s , where space euphoria caused young people to develop their own rockets. Since serious accidents occurred again and again, the safe model rocket construction was developed as an alternative.
The specifications for model rockets are laid down in NFPA Code 1122, those for high-power rockets in NFPA Code 1127, which in turn form the basis of the safety code for model or high-power rockets. There are no relevant regulations or a code for amateur rockets, so corresponding non-professional rockets that do not come under the terms model or high-power rockets are called amateur rockets.
A sub-form of amateur rockets are experimental rockets , in which all components including the motor are developed and built in-house. Commercially available motors can also be used for amateur rockets.
Regulations and Security
In contrast to model and HPR missiles, the construction and flight of amateur rockets is not standardized according to a code and must be done with the utmost care to avoid accidents. The legal requirements must be observed, so amateur rocket flight is usually only possible with certain permits from local authorities.
Records
The largest amateur rocket to date is a 1:10 model of the Saturn V with 8 times 13 kNs + 77 kNs propulsion, which was launched in the USA in 2009 and reached a height of over 1.3 km.
The largest European amateur rocket is the HEROS 3 rocket, which flew on November 8, 2016 on the European Space and Sounding Rocket Range at an altitude of 32.3 km. HEROS 3 has been developed and built by the Hybrid Engine Development (HyEnD) student team at the University of Stuttgart since 2012. HEROS 3 is a hybrid rocket that is powered by nitrous oxide and paraffin .
