Abstract: An annular aerospike nozzle for a vehicle, such as an upper stage rocket. is disclosed. The annular aerospike nozzle includes a centerbody and a plurality of thrust chambers spaced around the centerbody. Each thrust chamber has a throat and a nozzle portion extending aft of the throat. The nozzle portion has an exit dimension Dexit at an aft end. Each thrust chamber is spaced away from adjacent thrust chambers by a spacing distance Dspace, such that Dspace≥M*Dexit, where M≥1.
