Recent developments Students’ Space Association – Rocketry Group

Amelia 2 rocket

The idea Design methodology Main subsystems

Two-stage test rocket powered by two rocket motors

Both stages equiped with parachute recovery modules

Simple, low-cost rocket testing the possiblity of developing the full scale two-stage sounding rocket

Amelia 2 The idea

Mission profile

Amelia 2 Rocket configuration

I stage rocket motor

II stage rocket motor

Place for an optional larger rocket motor

I stage recovery module

II stage recovery module

Electronics and payload bay

Onboard camera

GPS Tracker

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

First stage: monoque structure

Second stage: stringers and bulkheads

Structure Amelia 2 rocket

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%

Recovery, stage seperation

Parachute recovery for both stages

Pyrogen expulsion

Final remarks

Conclusion What’s next?

Using the knowledge

earned during the

development of the

two-stage Amelia 2

and the simultaneously

developed one stage

CanSat Launcher

Possibilities

What’s next? Future plans

Conclusion

Launching small experiments

Demonstrating the capability to build

reusable staged rockets

Development of advanced solid rocket motor

technology

Cheap low altitude sounding capability

Possibilities
