Abstract:
The objective of this work is the development of an asymmetric roll formed W nozzle liner for the Polaris A-3 first stage. The process involved in making the parts consists of hot roll forming W plates to 60 degree and then 30 degree included angle truncated cone shapes, followed b hot power spinning the cones to the asymmetrical shape. A unique piece of equipment will make it possible to program the spinning of this eccentric shape this involves an hydraulic tracing mechanism following a template. Development work will be done first with mild steel and then with W. One end of the nozzle will be flanged and the liner cut free from the spun shape. The finished part will be pickled and electropolished. Tooling consists of a forming mandrel, a spinning mandrel, and a revolving tracing template.
