Abstract
A detailed numerical model to predict the buildup of cylindrical prefo rms in the Osprey process is described. A sensitivity study confirmed the importance of chamber design factors such as the direction of spra y on to the end of the preform, scanning amplitude, and scanning frequ ency with respect to preform rotation. The nature of the scanning moti on was also found to have a profound influence on the shape of the pre form end. (C) 1995 The Institute of Materials.
