Design and Analysis of Annular Aerospike Nozzle using CFD

Anthony Michael Bothe, Ohio Northern University

Abstract

A brief introduction to the Lockheed Martin X-33 project and Rocketdyne’s XRS-2200 project is presented as well as key advantages of aerospike nozzles over conventional bell nozzles. This article details the design, preliminary analysis, and evaluation of an annular aerospike plug nozzle using the simple approximate method for plug contour design. Plug nozzle contours were developed and computational fluid dynamics analyses performed. Conclusions are drawn from the data which promote understanding of the concepts of aerospike propulsion as well as present new ideas for aerospike research.
