The Ausroc 2.5 rocket is fuelled by Liquid Oxygen and Kerosene, and will
have a mass of 350 to 400 kg. The primary objective of the project is :
To launch a rocket with a 10kg payload to an altitude of 20km on a
ballistic trajectory and recover the vehicle intact.
This target altitude represents a higher altitude than has been reached
by any amateur liquid fuelled rocket worldwide, and represents a higher
altitude than has been reached by any prior Australian designed and
fabricated liquid fuelled rocket.
The Ausroc 2.5 rocket represents an intermediate stage between Ausroc II and Ausroc III, and is intended to incorporate as many elements of Ausroc III as possible while retaining a launch vehicle which can be readily designed and fabricated.
For example, the Ausroc 2.5 motor will have the same dimensions and geometry as the Ausroc III motor, but will be ablative rather than regeneratively cooled in order to ease fabrication.
The Ausroc 2.5 rocket has the following specifications :
- Launch Elevation: Between 70 and 80 degrees
- Propellant: Kero/Lox, Mixture ratio 2.4 (Lox/Fuel)
- Thrust at lift-off: 35kN
- Specific Impulse at sea level: 230s
- Combustion Chamber Pressure: 2MPa
- Launch Acceleration: 6-10 g
- Length : 7,230 mm
- Diameter : 305 mm (12")
- Control: 3 or 4 stabiliser fins
- Mass fraction: > 0.5
- Burn time: 10-15 seconds
- Fuel System: Regulated flow tank pressurisation system
- Drag Coefficient: < 0.8
The Ausroc 2.5 will be designed and fabricated in accordance with the ASRI Project Management framework, as a collaboration between ASRI members, students, universities and other interested individuals and organisations.
The Ausroc 2.5 team presently includes :
- Project Manager and Propulsion Team Lead : John August
- System Engineer : Mark Blair
- Recovery Team Lead and Administrator : Belo Ferreira
- Structures Team Lead : Andrew Barton
- Avionics Team Lead : Bernard Davison
We also anticipate contributions from the Swiss Propulsion Laboratory.
