Advances in Engine Burst Containment and Finite Element Applications to Battle-Damaged Structure
Abstract
Aircraft must be designed to sustain damage arising from the impact of a variety of types of projectiles such as military weapons and debris from engine disintegration. Recognizing the need for the collection and dissemination of information on this topic, the AGARD Structures and Materials Panel has set up a Working Group on the Impact Damage Tolerance of Structures charged with the task of producing a Design Manual. A specialist meeting was held in Ankara, Turkey in September 1975 and the conference proceedings have been published as AGARD-CP-186. Two further papers were presented to a private session of the Working Group in April 1976. The papers by Messrs. Bristow, Davidson and Gerstle reviews some recent research into the application of fragment impact studies to an understanding of engine burst fragment impacts and the initial development of an engine burst containment system. The paper by Dr Huang described a method of analysis of a battle-damaged structure using the NASTRAN structural analysis program supplemented by preprocessors designed to automatically generate input data; a 'patching technique' is then used in the development of a finite element model truly representing a battle-damaged structure.
