FABRICATION OF PROTOTYPE ROCKET MOTOR CASE BY CRYOGENIC STRETCH-FORMING

Abstract

Progress is reported on an experimental flight weight rocket motor cases of the Sparrow configuration by the cryogenic stretch-forming process. Achievement of B/P dimensions and determination of the suitability of the cryogenic stretch-forming process for production are the specific aims of the program. Techniques are being developed to achieve B/P dimensions in several areas of the Sparrow Motor Case. These areas included dimensional deviations in the contour of the hemispherical segment of the aftclosure and the diameter of the forward thickened ring. Both of these problems have been solved during this report period. Fabrication of the nozzle end ring presented a problem because of material springback during the mechanical stretch by a punch. During this report period, the feasibility of this method of fabrication of heavy rings was demonstrated, although one dimension was not achieved.
