A method of analyzing a structural component may include the step of storing one or more of the following on a server: at least one material allowable for a structural component, at least one load case for the structural component, and at least one analysis template having at least one analysis variable. The method may further include the step of providing, using an interface, at least one entry for the analysis variable. The method may further include performing, using a processor-based structural component analyzer, a strength analysis of the structural component using the analysis template and based on the load case and the entry for the analysis variable. The method may further include determining, using the analyzer, a margin of safety of the structural component based on the material allowable.

System and method for structural analysis

Systems for analyzing effects of cargo fire on primary aircraft structure are provided. A particular system includes a processor and a memory accessible to the processor. The memory includes instructions executable by the processor to access a thermal profile of a suppressed fire in a physical model of a cargo compartment of an aircraft. The instructions are also executable to analyze heat transfer resulting from applying the thermal profile of the suppressed fire to a structure of the aircraft surrounding the cargo compartment to determine a predicted temperature reached by one or more parts of the structure surrounding the cargo compartment as a result of the suppressed fire. The instructions are also executable to generate an output including the predicted temperature reached by the one or more parts of the structure surrounding the cargo compartment.

Analysis of effects of cargo fire on primary aircraft structure temperatures

Embodiments provide systems and methods for analyzing effects of cargo fire on primary aircraft structure. A thermal profile of a suppressed fire in a cargo compartment of an aircraft is developed. The thermal profile is applied to a heat transfer model of structure of an aircraft, and structural integrity of the modeled structure is analyzed. The thermal profile may be developed by introducing a fire in a physical model of a cargo compartment instrumented with temperature sensors and determining profiles of temperature versus time. A heat transfer model of aircraft structure is built, boundary conditions are input into the heat transfer model, and the model is run. When analysis of the modeled structure determined structural integrity to be insufficient to satisfy flight certification requirements, structural parameters are modified, the thermal profile is applied to a heat transfer model of the modified structure, and the analysis is repeated.
