Side Vector Control Through Jet Wall Interactions in Segmented Ejector Nozzles.

摘要

It has been suggested that a non-symmetrical supply of secondary air to an ejector nozzle and consequent deflections of the primary jet could be used as a method of side vector control. Experimental support for this scheme has been sought;however,it did not indicate that significant side forces could be achieved. The investigation aimed at the theoretical analysis and experimental verification of side vector forces produced in segmented short-shroud ejectors by controlled admission of secondary air.
