The H11 Rocket
Contents
1 Design
2 Flights

The purpose of the H11 rocket is to have a easy to fly, cheap to operate rocket. The existing NERO Haarlem rocket architecture, (as used in the H6-H9) was completely revised en updated. Both the H10 and the H11 are build with this architecture, so parts are easily interchangeable.

The H11 is primary build to perform qualification of mechanical and electronic parts for the H10 project. The decision to buld this rocket has been made after de H10 project has started, that's' why the h11 flew before the H10.

Design [Top] [Contents]
The design is a straight-forward design, using the Thrust-18 motor for propulsion, the standard parachute-set and the Von Karman-shaped nosecone. Bottom-up the H11 has following compartments, but its configuration can be changed according to the specific demands for the qualification flight.
  • Thrust-18 motor
  • An electronic compartment with the RDAS and battery for flightcontrol and data acquisition
  • An standard NERO parachute compartment
  • Pay-load, or the parts that has to be qualified
  • Standard nose-cone.
Lugs are used to launch the H11 from the NERO launch rail.

Flights [Top] [Contents]
The first flight of the H11 on May 7, 2004 resulted in a misfire, because the Thrust-18 motor did not ignite. This was solved by a modification to the Thrust motor, and a break membrane was introduced. The second attempt on June 18, 2004 was a success.

The first three flights of the H11 did mainly qualify the Thrust motor as first stage rocket motor. The fourth H11 flight is qualifying the Vubonite nosecone for the altitude project, together with the H10-gyroscopes.
