Compound aerospike nozzles were designed and tested as part of an ongoing
experimental study to determine the feasibility of thrust vectoring an aerospike
nozzle with the addition of a secondary port. Earlier phases of the study have
indicated that a compound aerospike nozzle could provide sufficient thrust
vectoring. The addition of a hole-type secondary port was found to provide
effective thrust vectoring.
Experiments were carried out to determine the effects of secondary port size,
secondary port inlet geometry and compound aerospike nozzle chamber
pressure. Results show good predictability, axisymmetric flow, and emphasize
the importance of a radius on secondary port inlet geometry.
