Improve aircraft fuel efficiency, structural performance, aerodynamics and many other aspects of aircraft design with ESTECO technology, used by major organizations such as Embraer, Leonardo, Gulfstream, EADS and ONERA.

Today’s aerospace and defense industry faces many challenges. Due to the projected growth of air traffic, commercial airplane manufacturers see a strong need to minimize fuel consumption, emissions and noise, in order to satisfy consumer and regulatory constraints.

Since these requirements typically lead to conflicting design objectives across several domains, employing Multidisciplinary Design Optimization (MDO) in the design process is crucial. Military airplane manufacturers on the other hand have an entire different set of challenges to solve, mostly involving aircraft performance, power and thermal management requirements and energy efficiency.

The aerospace industry has traditionally often used conservative design methods with a siloed approach between different disciplines. To meet future challenges however, more innovative technologies are needed, and collaboration will be key, not just among different design departments, but also between OEM and suppliers. ESTECO’s technology is designed to do just that.

Supporting designers in integrating disciplines and balancing multiple, opposing objectives

modeFRONTIER supports design teams in building a multidisciplinary design framework, which allows for design space exploration, optimization (direct and RSM based), trade studies and sensitivity analysis, robust design and reliability, visualization and multi-criteria decision making. ESTECO proprietary algorithms deliver reliable methods for identifying the best solutions possible when dealing with complex multidisciplinary aerospace design problems.

Keeping people, processes and technologies together

VOLTA, the web-based design optimization environment, enables engineers to collaborate on the design of all aircraft components and subsystems at once and speed up the decision-making process. VOLTA - ESTECO solution for enterprise-wide collaboration - helps manage all cross-functional concurrent design steps by integrating multiple modeling formats. Its service-oriented architecture facilitates the execution, sharing and  re-use of the enterprise engineering knowledge. 

Applications of ESTECO technology
in the aerospace industries

modeFRONTIER is used by major companies and institutes in aerospace, such as Embraer, Gulfstream, EADS, and ONERA. Engineers in the field use modeFRONTIER for:

  • wing design and aerodynamics
  • fuselage shape
  • aircraft structural components
  • aeroelastic systems
  • micro-air vehicles
  • acoustic emissions
  • metal sheet thermal forming
  • impact damage prediction
  • turbine blades
  • composite materials
 

Few examples:

This study by Embraer and ITA is intended to present a two step methodology for the structural optimization of a preliminary composite wing based on automatic zone modelling strategy followed by GA iterations.

The main objective of this paper is to study and to propose a methodology in order to obtain an optimized internal wing structure of the UAV aircraft. Such optimization takes into account the static aeroelastic effects of Fluid-Structure Interaction (FSI) through Computation Fluid Dynamics (CFD) techniques coupled with the Finite Element Method (FEM).

This paper describes how the adjoint approach can help the designer to efficiently reduce the flow separation onset at wing–fuselage intersection and to optimise the slat and flap positions of a 3D high-lift configuration. The optimisations were performed within a limited number of flow evaluations, emphasising the benefit of the adjoint approach in aircraft shape design.
