Focus of Project RHEA
The main goal of project RHEA is to pave the way for ARIS’ own developed hybrid rocket engine which will then be integrated into ARIS rockets for the Spaceport America Cup from 2021 onwards. To achieve this, the first generation of a hybrid rocket engine will be developed, and a test facility will be set up.
A small team of 9 students is currently defining the project, establishing
the first concepts for the testing infrastructure and the engine as well as
bringing together partners from academia and industry.
DEVELOPMENT OF G1
As a first step, a 500N hybrid rocket engine is developed laying the foundation for future engine developments at ARIS. This engine will be designed, manufactured and tested until the end of 2019.
DEVELOPMENT OF G2
The second generation will be developed by the ETH Focus Project IRIDE, aiming for a thurst of 5000N. Different nozzle types and grain structures will be tested to increase the performance.
To test the engine, project RHEA will set up a test facility with a fluid supply system for the oxidizer as well as a data acquisition and control system to control the valves.
Contains a test bench on which the engine is mounted, and the thrust generated by the engine can be measured.
Stores and transports the oxidizer into the combustion chamber of the engine located in the engine compartment.
Contains all electronic modules to receives the sensor signals and to control the Fluid Supply System and the ignition.

Assembling the system
During June and July, the system was united. First, the shielding plates, which separate the engine and FSS compartment, and the testbench were integrated, followed by the FSS system and cable trays. In parallel, the electronic boxes were assembled.
