Space launch and satellite propulsion engineers strive for every little improvement in system performance to increase payload capacity. Aerospike nozzles, with their altitude-adaptive characteristics, can provide such an additional performance gain in comparison with conventional bell nozzles. A key aspect for the successful implementation of this advanced nozzle concept is thrust vector control (TVC). This paper provides insights into the impact of aerodynamic TVC on the nozzle surface and base pressure distribution of a linear aerospike through secondary injection. The results presented are obtained via cold-gas experiments on a linear aerospike nozzle, providing a reference and starting point for further numerical and experimental analyses. View this paper
