Examples in Context

  1. A newly developed helicopter rotor aeroacoustics code and newly obtained unsteady surface pressure data on the blade of a model helicopter rotor are used to predict rotor blade vortex interaction noise.
  2. Prediction of rotor blade vortex interaction noise using 3 D unsteady surface pressure
  3. Theoretical study on the blade - vortex interaction noise of helicopter rotor
  4. The results shows : the scale of top blade clearance is closely relative to the strength of leakage flow and distribution of tail trace position in passage, the leakage flow and passage vortex interaction has seriously affected the flow field distribution of inner passage.
  5. Wall flow patterns on the blade surface and hub surface are found out. The complex vortex system structure, such as horseshoe vortex, passage vortex, corner vortex and trailing vortex, and the interaction with shock wave system are researched.
