Numerical Investigation of the Effect of Base Bleed on Thrust of a Truncated Aerospike Nozzle in Off-design Conditions

Aerospike nozzles are known to produce more thrust than conventional convergent-divergent nozzles in off-design conditions because of their capability to adapt their boundaries to ambient conditions. However, the central plug of an ideal aerospike nozzle can be very long and heavy, and its sharp end is susceptible to deformation in high...
