8.1.8 Flow Rig
The Flow Rig is a test system, used by the EPL for the performance testing of components intended for use within a chemical propulsion system. The objective of the Flow Rig is to measure the pressure drop of water passing through a test component installed within the testing section of the Flow Rig and at a later date, water hammer effects.
The Flow Rig requires that pressures, temperatures and mass flow of the working fluid are measured in order to determine the performance of a test component.
The working fluid used for the Flow Rig is distilled water. The pressure drop characteristics of the water are measured throughout the system. This allows a good approximation to be made of the characteristics that would be expected when using other fluids by comparing the thermodynamic properties of both the water and the working fluid intended for use.
Test procedures have been written for pressure drop tests, and the first test campaign has been done. But an evaluation still needs to be done, to achieve full commissioning.
The user manual can be found in RD12.
A picture of the installation is given in Figure 11.

8.7 Data Acquisition Systems
The EPL signal acquisition systems are built around National Instruments systems.
The EPL has seven DAQ which consist of at least a PXI-1052 chassis, an embedded controller and an optional ADC card (usually PXI-6220 or 6221). Two other DAQs are dedicated to CORONA, FEEP, Gigant and SPF feedback/diagnostic systems. These systems are listed below (Table 12).
These systems can be equipped with a wide variety of acquisition/conditioning cards listed in Table 12.
