Design of a Small Scale Aerospike Nozzle and Associated Testing Infrastructure for Experimental Evaluation of Aerodynamic Thrust Vectoring

A system for cold ow testing of an aerospike nozzle has been developed in an e ort to examine the e ectiveness of aerodynamic thrust vectoring and truncated nozzle base bleed. These tests are designed to produce results that will support the design of a system for hot ow testing of the same technologies. Design of a nozzle suitable for testing with reasonable cold-gas mass ow rates and measurea...

Reacting Nozzle Flow

The two limits, “frozen” and “equilibrium” flow share an important property: both are isentropic flows (if we ignore friction or heat losses). This is because, in the frozen case no chemical change during expansion), there are no rate processes at all occurring, the molecules preserving their identity all the way, while in the equilibrium case, in which reactions do occur, their rate is so high...

Flow Field Characteristics of an Aerospike Nozzle Using Different Turbulence Models

To improve the calculation of the flow properties of an aerospike nozzle, different turbulence models were investigated in this study. The primary shape of the nozzle plug is determined through utilizing an approximate method. The flow field is, then, simulated using the Navier-Stokes equations for compressible flows. The commercial computational fluid dynamics code Fluent is used to simulate t...
