LRI-AAST: L1 and L2 laboratory DACS systems
| Lab | Equipment |
|---|---|
| L1 - DYNO and CORE test cells L2 - PROP1 and PROP2 test cells |
Data Acquisiton System The test cells are equipped with large DAS that can be grouped together for more channels if necessary |
| Measurement | No | Range | Notes |
|---|---|---|---|
| Fuel Flow* | 2 | 0-800 pph | To be installed on facility piping. From fuel tank to engine FMU. Redundant turbine flowmeters. The flowmeters should be volumetric; the mass calculation must be done in the LF system real time calculation. |
| Fuel Flow* | 2 | 0-2500 pph | To be installed on facility piping. Motive Flow From FMU recirculating. Redundant turbine flowmeters. The flowmeters should be volumetric; the mass calculation must be done in the LF system real time calculation. |
| Fuel Flow* | 1 | 0-1 kg/dm3 | Densimeter on facility piping for gr from volume to mass |
| Fuel Flow* | 1 | 0-800 pph | Coriolis fuel flowmeter to be used for check consistency. |
| Fuel Pressures* | 3 | 0 - 70 psig | From facility tank to FMU and motive flow from FMU to recirculation. |
| Fuel temperature* | 6 | Ambient Temperature | To be installed on facility piping near each flowmeter and before FMU |
