SRP V

From Dare

SRP V is the fifth launcher of the Small Rocket Program. Together with the SRP IV, SRP VI and SRP VII it will take part in the Scrambled Eggs Competition. The SRP V has been developed by a group of four new DARE members who joined in 2006. The rocket is currently being produced and is scheduled to be finished in May 2007. The launch date and location are still unknown.

Rocket Concept

The rocket hull consists of a PVC tube with a diameter of 110mm. It is a three engine cluster rocket, meaning the rocket is powered by three engines which ignite and burn simultanously. These are 40mm PVC SRP engines with a KNO3/Sorbitol solid fuel, a total impulse of 180 Ns and a burn time of 1 second. The rockets bulkheads are made of MDF (Medium Density Fiberboard), attached with epoxy and steel brackets. The recovery system consists of the PerfectFlite microTimer 2 electronics, a parachute system and pyrocharges. The pyrocharges will seperate the rocket at the parachute compartment, thus deploying the parachute. The nosecone is made out of polystyrene and will contain an egg which needs to be safely returned as part of the competition.
