Vl Capability

The reason for the need of the boost stage of an engine main fuel pump to have a V/L capability and some detail of the design requirements has been presented in previous discussions. The test set-up used for V/L testing is similar to the example shown in Figure 7. The testing is usually accomplished in two parts. Both parts are run with the maximum fuel RVP expected in service. The first part is to evaluate the V/L performance of the pump at all of the specified emergency conditions and prove all conditions can be met. The second part is an endurance test at high V/L conditions to ensure that no excessive cavitation erosion damage occurs that could limit the performance or life of the pump.
