New Robust DESIgn Guideline for Imperfection Sensitive COmposite Launcher Structures

Objetivo

"European Space industry demand for lighter and cheaper launcher transport systems. The proposed project DESICOS contributes to these aims by a new design approach for imperfection sensitive composite launcher structures, exploiting the worst imperfection idea efficiently: the Single Perturbation Load Approach. Currently, imperfection sensitive shell structures prone to buckling are designed according the NASA SP 8007 guideline using the conservative lower bound curve. The guideline dates from 1968, and the structural behaviour of composite material is not considered appropriately, in particular since the imperfection sensitivity of shells made from such materials depends on the lay-up design. The buckling loads of CFRP structures may vary by a factor of about 3 just by changing the lay-up. This is not considered in the NASA SP 8007, which allows designing only so called ""black metal"" structures. Here is a high need for a new precise and fast design approach for imperfection sensitive composite structures which allows significant reduction of structural weight and design cost. For most relevant architectures of cylindrical and conical launcher structures (monolithic, sandwich, isogrid - without and with holes) DESICOS will investigate a combined methodology from the Single Perturbation Load approach and a specific stochastic approach which guarantees an effective and robust design. A recent investigation demonstrated, that an axially loaded unstiffened cylinder, which is disturbed by a large enough single perturbation load, is leading directly to the design buckling load 45% higher compared with the respective NASA SP 8007 design. All results will be summarized in a handbook for the design of imperfection sensitive composite structures. The potential will be demonstrated within different industrially driven use cases."
