German Aerospace Center DLR, Stuttgart
MTT provided for DLR a lab-unit that comes with the extra sensoring, control software and support to run in test and lab facilities.
Context
DLR sought a cost effective test environment for micro gas turbine educational purposes and R&D & application studies.
The Use Case
Save costs by testing at small scale:
- 3 kW electricity, 15 kW thermal
- Low cost, light weight, small size
- Low infrastructure requirements
- Low operating cost (low fuel consumption, low maintenance)
Recuperated micro gas turbine designed for:
- Micro turbine R&D studies
- Turbomachinery optimization
- Cogeneration / CHP concept studies
- Alternative fuel studies
- Novel combustion concept studies
The role of the EnerTwin
LabView program:
- Award winning design
- Code included (optional):
- For adapting schedules
- Monitoring & data logging:
- Performance
- Vibration (optional)
- Control:
- Automatic (start up, load variation etc)
- Manual (turbine speed & power setting)
- Temperature
- Clear overview of thermodynamic process:
- Micro turbine performance
- Thermodynamic cycle
- Gas conditions at engine stations
Includes extensive instrumentation:
- Sensors at all critical process stations
- User-friendly control
- Accurate performance monitoring
- Remote control (optional)
- Code included (for adaptation)
The benefits and conclusions
- Low fuel consumption
