10. Aerothermodynamic analyses in ANSYS Fluent –
main body
All elements modeled in CATIA
Loads calculated analitycaly, use of FEM (ANSYS)
Developed computer software:
- solid rocket motor optimization
- interior ballistics simulations
- composite case optimization
Design methodology

11. First stage:
monoque structure
Second stage:
stringers and bulkheads
Structure
Amelia 2 rocket

12. The same rocket motors in both stages
during the first flight (simplicity)
Self-developed technology
- reusable composite solid rocket motors
Ammonium Perchlorate composite propellant
Specific Impulse - 225 s
Rocket motors
For the Amelia 2 rocket
• 0,43 kg of solid rocket propellant
• Composite structure
• Propellant mass fraction > 45%
