By means of the fountain-convergence analysis method of FRRU (Flow Resistance-Rigidity Uniformity) index defined by the author, evidential comparison analysis study has been made to the relationship between flexible drift of flow performance of WTD (Weight Type Distributor) valves of fuel nozzles of X engine and hot-end failures of X engine. The results show that during the initial period of engine start, because of the relative scarcity of air in the combustor, a convergence characteristic, due to its converging flow property ofmultiple to one, can lead to such hot-end failures as turbine blade fusion break which is characterized byabrupt change, while a fountain characteristic, due to its diffusing flow property ofone tomultiple, cannot result in any hot-end failures.

Simulation Results

This paper optimizes the structure of the poppet valve based on the internal flow. The flow-force on poppet valve in the case of the converging flow is simulated and studied by CFD. Simulation results represent that the traditional formula for computing the flow-force can be used only in the certain range, so the formula is modified based on the simulation result.
