Since 1959 NERO members design, build and
launch rockets. On this and the many subsequent linked pages you'll find information about some of the many NERO
rockets. From the first documented rocket the H1 up to the recent H10, that will compete for the European
altitude record. |

Three types of amateur rocketry exists: |
|
|
Model rocketry: small lightweight rockets that are
mostly exact scale models of their big brothers. Small engines are used and the rockets are mostly made of
lightweight - non metal - materials. |
|
High power rocketry: large rockets, but the use of
metals is restricted to the motor casing and small parts. Often a rocket kit is used, and the motors need to be
bought from designated suppliers. A strict certification system is used for buying motors and launching rockets. |
|
Experimental rocketry: the "no restrictions" class of rocket building. Rockets are build out
of metal (aluminium) and the motors are developed from scratch. NERO builds experimental rockets and on these
pages we'll show our rocket motors.

|
The NERO has member groups for experimental
rocketry and modelrocketry. |

Our present-day rockets are sounding rockets, built to provide
insight into the dynamical behaviour of the rockets during flight. These rockets are therefore equipped with
measure and control systems which collect flight data and control the flight itself respectively. In order to
recover the rockets without sustaining damage, 1 or 2 stage parachute systems are used.
NERO uses a numbering scheme for its rockets. For instance every NERO Haarlem
rocket is designated with the letter H (for Haarlem), followed by a number. For each (planned) flight of the
rocket, a subsequent letter is added. The first flight of the H6 is called H6a, the second H6b and so on.
On the linked pages below you will find links to pages providing a lot of
information about some of the rockets which have been built and launched by NERO during the last decade. Around
20 web pages are given containing general overviews of the sub-systems used in the rockets as well as extensive
reports on their respective flights, including what went right and what wrong.
The H1 to H4 rockets were small experimental rockets. Very little can be found
about these rockets in the NERO archives.
This is different for the more recent rockets. An increasing amount of data is available for these rockets and
the following pages will show this.
The H10 and H11 are specially developed to break the European altitude record.
