Projects and Rockets

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.




Experimental rocketry [Inhoud] [Top]

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.


The following table provides an overview of the development of NERO Haarlem rockets.
