A modeFRONTIER case study about the optimization of the windshield structure

DEMA SpA must assess the capabilities of a methodology for the smart analysis of the windshield structural behavior by using a FE (Finite Element) model integrated with modeFRONTIER for a new Canadian business jet. The methodology would be able to automatically change the thickness of the Global Finite Element Mode (GFEM) shell elements, run the new numerical analysis and finally obtain a configuration with a minimum mass target, but at the same time able to stay within a well-established threshold stress. 

Blade fir tree design by genetic algorithm method

This work design an automatic process governed by modeFrontier to optimize the fir tree shape using  an adimensional parametrical model in MSC/Patran. The process run automatically different engine like Matlab for preliminary calculation, Patran and Nastran for detailed calculation. The process produce optimized solutions in compliance with all the design criteria.
 

Analysis of buckling and structural optimization of low-pressure turbine casing for a civil airplane engine

The principal aim of this work is the optimization of the casing geometry in order to reduce the structural weight, increasing the resistance to the buckling collapse. We will use the FEM model choosing opportunely some geometric parameters, to define the design--space of possible geometric cross-section shapes. We operate the optimization under the worst load case chosen between the estimated work conditions.

Investigation into optimised composite scarf repairs with practical constraints

Composite materials are widely used in the aerospace industry for their high specific properties and are now being used in structurally critical components, whereby total failure of the component would lead to catastrophic failure of the aircraft. 

Auxiliary Power Unit Compartment Design Optimization

In this paper a design process of auxiliary power unit (APU) compartment is presented. APU is an additional engine, used in air-vehicles development, which provides power to start the main engines, runs accessories while the engines are shut down and provides electrical and hydraulic power (depending on the design) before engine start (pre-flight tests, cabin ventilation, etc.).

Strength Improvement to Composite T-Joints under Bending through Bio-inspired Design

This paper shows that a bio-inspired design methodology is an effective method to strengthen composite T-joints under bending loading, whose ply angles were tailored using an optimisation program mimicking the evolutionary process of adaptive growth.
