Abstract

The aeroacoustic characteristics of an over-expanded annular aerospike nozzle have been studied. The overall sound pressure levels of the aerospike nozzle are compared with the levels obtained from a convergent divergent nozzle for a given pressure ratio of 2.57 for the over-expanded condition. It is observed that the over-expanded annular aerospike nozzle generates screech tones at this NPR and in general shows higher OASPL levels than the over-expanded convergent-divergent nozzle at peak radiation direction.
