The time-averaged thrust of an incompressible fully pulsed jet containing a period of no flow between pulses is studied experimentally as a function of pulsing duty cycle SrL and the ratio of the ejected slug length (per pulse) to the jet diameter L/D. The parameter ranges investigated were 2 <– L/D <– 6 and 0.1 <– SrL <– 0.98. Significant thrust augmentation by pulsing was observed over the entire parameter range tested, both in terms of thrust compared to an equivalent steady jet with… CONTINUE READING
