| Popis: |
A thrust stand capable of measuring the time averaged thrust produced by a PDE was designed and tested. The study quantified the effect of exit nozzles on a valved multi-tube PDE system with three tubes arranged in a close-packed configuration. Three nozzle geometries were considered; straight, converging, and converging-diverging. Numerical simulations were also performed of a single detonation chamber with the same nozzle exit geometries. The test measurements are used to validate the predictions of time-resolved pressure, and the thrust predictions from the limit cycle model of PDE. Comparisons of trends in test measurements and model predictions of pressure-time traces and thrust show good agreement, for all the nozzles considered in the present study. |
