| 内容記述 | In the development of the Japanese original booster rocket engine, designated the LE-7, four methods of fabricating the thrust chamber were investigated; the CIP (Cold Isostatic Pressing) forming method, the nickel electroforming method, the diffusion bonding method and the brazed copper powder method. The objective of the present report is to comparare and evaluate these methods from the standpoint of maximum elastic stress on the thrust chamber wall. The slotted thrust chambers to be analyzed were designed according to the LE-7 engine specifications. The pressure and thermal loads on the chamber wall are taken as the boundary conditions in the following analyses. As the first step, for simplicity, axisymmetrical thin shell model analysis was conducted to evaluate the whole stress field of the chamber. Then two dimensional elastic analysis was performed at the throat plane where the maximum stress existed. These analyses proved that, of the four methods, the CIP forming method has the lowest stress fieid. Further analysis showed that the CIP method could be improved by inserting a thermal insulation layer between the CIP closure and the external jacket, thus decreasing the maximum stress on the chamber wall. | |||||||
