Aerospike nozzles are now-a-days one of the
most emerging topics for research and development work
leading for the futuristic goals of an aerospace industries
and organizations. They are indulging in a class of
elevation balancing nozzle engines. These nozzle engines
are basically constructed for single-stage-to-orbit (SSTO)
as well as foremost engine for space vehicles. These nozzles
are about 75% shorter than the standard nozzle for
similar expansion ratios. Aerodynamic thrust variation
and performances play a key role in estimating forces
along with the injected flow and their characteristics. This
review paper deals with the aerodynamics
characterization, its properties at different conditions in
addition with the performance analysis of the aerospike
nozzle.
