Abstract : The objective of this program was to obtain parametric type data on advanced lightweight containment systems. These data were used to generate design methods and procedures necessary for the successful development of such systems. The methods thus developed were then demonstrated through the design of a lightweight containment system for a CF6 size engine. The containment concept evaluated consisted basically of a lightweight structural sandwich shell wrapped with dry Kevlar cloth. The initial testing was directed towards the determination of the amount of Kevlar required to result in threshold containment for a specific Set of test conditions. A relationship was then developed between the thickness required and the energy of the released blade so that the data could be used to design for conditions other than those tested. The remainder of the testing was directed towards the evaluation of a number of variations in the basic concept. Using the data from these tests, a lightweight containment design was made for a typical large turbofan engine. Based on this design, a weight saving in the range of 20% to 25% over current containment systems was projected.
