LRI-AAST: L1 and 2 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 |
| Time (GPS Synchronization system) |
1 | N/A | Needed to synchronize all systems. At least 1O H z is required. |
| lnlet Temperature | 4 | Ambient Temperature | To be installed on test cell inlet |
| Test Cell Pressures | 4 | Ambient Pressure | Front/Rear test cell pressure. Probes to be included. |
| Test Cell Temperatures | 4 | Ambient Temperature | Front/Rear test cell temperatures. Probes to be included. |
| Engine Torque (Dyno Test Cell) |
1 | Lb*ft | lnline torquemeter |
| Environment | 1 | Ambient Humidity, Temperature, Pressure |
Weather station to be installed outside test cell. |
| Test Cell lnlet Temperature | 4 | Ambient Temperature |
4 RTDs on test cell inlet |
| Airflow | 1 | Engine lnlet Airflow, Dyno Test Cell | Ref. dyno test cell RFQ and below notes about standard instrumentation. |
