| Abstract: | The present subject matter discloses a ventilated cowl device (302) for increasing the thrust of an aerospike nozzle (102). The ventilated cowl device (302) comprises a cylindrical surface having cross section same as the aerospike nozzle cowl end (110) cross section. The ventilated cowl device (302) further comprises a series of ventilation holes (306) drilled at an equal pitch from one another on the cylindrical surface, where the interaction between the aerospike nozzle jet and freestream flow result in the generation of shocks from the ventilation holes (306) that increase the thrust of the aerospike nozzle (102). |
