Abstract
The present invention provides a pressure vessel having a non-circular axial cross-section, and a method for its construction, which achieves improved reliability, minimum weight, minimum cost, and maximum aerodynamic smoothness. The above characteristics are achieved through the use of honeycomb cores whose thickness varies in accordance with the distribution of bending moments created by the non-circular axial cross-sectional configuration under internal pressure. The present invention also provides a pressure vessel having a non-circular axial cross-section which may be especially designed to meet preestablished design criteria for optimal weight, volume, and strength.
