Project overview:
Solid rocket motor built to power Latin cup challenge rocket.
Project specifications and design:
Aluminum 6061-T6 casing for lightweighting
EPDM rubber used for ablative liner
Design impulse 3200Ns
KNO3 used and oxidizer and Sorbitol used as fuel in 65:35 ratio
Double O-rings as well as silicone sealant used to prevent gas leakage
Test stand integrated with data acuisition system, loadcell and remote ignition system
Bulkhead or motor designed to integrate with the bulhead of the rocket via an eyebolt
Internal-Ballistics Simulation
Internal-Ballistics Simulation
Extensive internal ballistics and chemical equilibrium analysis were performed
Compressible flow simulation of gasses in the nozzle
Compressible flow simulation of gasses in the nozzle
Simulations were used to validate our compressible flow calculations, In house Python code was also developed to speed up calculations and for iterative design process
FEM simulation on motor bulkhead
FEM simulation on motor bulkhead
FEM simulations used to validate our hand calculations of the structural bulkheads and bolts used.
A good design is designed not to fail, a great design is chosen how to fail. We had structured our Factors Of Saftey of our design elements for the nozzle fail first in case of over-pressurization of the chamber. As failure of the casing or bulkheads yields to be more catastrophic
