    Problems related with the optimal contouring of two-dimensional and axisymmetric spike nozzles providing maximum thrust for given dimensions and external pressure are studied. The nozzles Cited by: 7. Annular and linear nozzles, designed to compensate ambient pressure variation, like the Aerospike nozzle. They are under development. We present below the 1D model of gas flow in nozzles. For more realistic design, beyond this simple model, a 2D (or axisymmetric) analysis by the method of characteristics and boundary layer effects File Size: KB.

Command Line. The aerospike engine employs a high-efficiency nozzle, or spike, to direct the flow of high-pressure gas emanating from the thrust cells. The surface of the spike restricts expansion of the gases against the curved inner wall of the rocket, while a cavity at the top of the spike allows a subsonic flow field to recirculate at its base.

Aside from a spate of research in the early s, the concept of the plug nozzle appeared to be nothing more than a footnote in aersopace history.Linear Aerospike: All of the nozzles we have studied thus far have been annular, or circular when viewed from below. Still another variation of the aerospike nozzle is not an annular nozzle at all.

A second approach, pioneered by the Rocketdyne company (now a division of Boeing) in the s, places the combustion chambers in a line along two.
